This tutorial will cover the teardown and repair of a robot vacuum that is having problems driving straight and sometimes shuts down. I will walk you through the repair of this machine down to repairing the motor that causes the issues.
If your robot vacuum runs into things a lot instead of avoiding them, see this video by Dallen Hansen for a fix:

Just wanted to give you a big thanks for this video.
We have the Ecovacs Deebot N79 (model DN622.11), which as someone else in the comments has said, is internally exactly the same as the one in the video. Our Deebot would basically start running then turn in circles for a few seconds and start bleeping with an error. On testing the wheels, like you show in the video, it was obvious that It one wheel motor wasn't turning properly and was shorting.
Following this video I was able to clean out the carbon from the motor, clean up the commutator and get it working perfectly again. I'm subscribing and bookmarking this video for future reference.
Thanks again!
That's awesome! Thank you for the info and comments. It will surely help out others with different brands.
Wow, without the internet I would be buying a new one. What a time to be alive. Thank you so much!
You are very welcome! Thank you for commenting!
Thank you for your detailed step by step instructions. Appreciate it.
You are welcome! Hope it helped. :)
Great job. With your help got my Eufy 30c back up and running.
Glad I could help
Thank you so much for these detailed instructions. They really helped me out.
You are very welcome!
Thank you! That's exactly what was wrong with my Eufy Robovac 11+ and your video saved me from throwing it in the trash!
Your comment made my day. :) So glad you got your Eufy running again!
@@AlsAutoandAppliance By the way, in case someone comes across this with the same model: this one has a motor with a press-fitted gear made from brass, not plastic. I was not able to remove it, but the good news is that just removing the plastic back gives plenty of clearance to clean the rotor with a metal dental pick, followed by an old toothbrush and a blast of compressed air.
Also, make sure you de-solder and re-solder the condenser's lead that is coming out of the motor and attached to the PCB (someone at Eufy had a "bright" idea of jamming two condensers inside the motor). That was tricky because it's so thin and barely noticeable.
Thank you so much for this video. God bless you 🙏
God bless you too! Hope you are back up and running. :)
Thank you so much for this detailed and hands on video. I almost threw out my robot and this video saved it.
P.s. I have the Ecovacs Deebot N79 and it's exactly the same.
You are welcome and thank you for the info about the Deebot. This will certainly be useful for many folks out there. So glad you were able to rescue yours before going to the landfill. : )
Fantastic. My EUFY Robovac 11c had become excessively noisy and was destined for replacement until I watched your video. Now running quietly and efficiently again. Issue inside the motor housing with some gunk that had worked its way right in there. Thank you
You are welcome! Glad you were able to give your vac a second chance at life!
Thank you for the detailed instructions! The motor being clogged with carbon (or whatever) was definitely my problem. The only thing I struggled with was releasing the tabs for the motor housing. Mine were much smaller than yours but I got them. I had also never taken apart an electric motor so if anyone is looking at this and thinking it is too complicated, it isn't!
You are very welcome! Thank you very much for your words of encouragement to the viewers. The worst that could happen is you break a motor that's already broken and at best you come away from it knowing a little bit more than you did before diving in and trying the repair! :)
Great video, thanks for the in-depth explanation and repair instructions. Prior to watching I was really worried about whether the issue was the motor, control board, or something else, but trying to spin the wheel narrowed it down to the motor short. I'm having the same issue on my Robovac 11S, where the wheel modules are fortunately MUCH easier to remove compared to the Robovac 11 in the video (4 screws and it lifts out, the most annoying part is detaching the ribbon cable). I contacted Eufy to see if they're willing to sell me a motor module, but in case they aren't I noticed that there are 3rd-party replacement parts available in various places online: they simply sell the entire wheel module.
Eufy 12 motors have their own access covers so are much easier to access. A _lot_ of crud came out of the motor once I opened it up. The rotor looked OK otherwise, so I put the cover back on the motor, reassembled, and all was well with the little vac.
Thanks for the great video that saved me bucks!
You are welcome! Good to hear you got yours running again and that there are access covers on your model. :)
Brilliant detailed video thanks. My eufy 30c is not longer going around in circles and I learnt how to clean an electric motor :)
So awesome to hear success stories! Thank you for posting! :)
Thank you for the detailed video. I am going to follow it and try to fix my robot vacuum. It just goes around in circles. The video looks very easy to follow. I hope that I am right.
fantastic video diagnosed my problem in the first 3 min thank you
Glad it helped you out. :)
Fantastic, you rock... thank you so much for sharing this fix.
You are welcome! Thank you for watching. :)
Nice detalied instructions on the breakdown of this unit. I have a Coredy robovac R700 and it is very similar - enough so that I could take it apart from this video. Funny thing is I was getting two codes - the solid light beeps once and the solid light 4 beeps and it was going round in circles. I cleaned out a little dust and hair but I didn't take the gear case off the wheels. Finally decided that if any of the motors were bad that I would have to just recycle the whole unit, but when I put it all back together it worked and no more codes, so I don't know what happened but it's up and running again for who knows how long. Thanks!
Thank you so much for the kind words and telling your story. Great job getting it running again! It doesn't take much hair and debris to cause problems. Also, I've had a pet edition eufy that went in circles and that wound up being an axle becoming separated from it's drive gear. It was intermittent but only happened when on carpet. That fix is a whole other video, which I have not made yet. Good fix and hope you're good to go for a long while. 👍
Thanks so much for the detailed guide!
I was searching the web for a replacement motor without any luck, but it didn't come to my mind to open the faulty one and give it a good clean...
Thanks to you my Robovac runs like on the first day again!
That is awesome! Congrats! :)
It worked for my eufy robotic 30! Thanks for your video!!
Awesome! You're welcome!
Thank you so much, works fine after cleaning!
You are welcome!
Really a great video to follow, thank you!! Cant seem to turn that screwdriver quite as quickly as you yet though!!
Thank you for the compliment! :) Yes, years and years of practice (and maybe some video editing) will get you up to speed screwdriving. ; )
Solid vid! Thanks for sharing
Thank you, and you're welcome! Hope it helped. :)
We have two! this is an amazing fix!
Thank you!
Coming back to say that a month later after fixing the right wheel, the side brush motor has failed on my Eufy.
I followed the same procedure and it's running again!
So that's my second time saying thank you!
And you are quite welcome again! Thank you for coming back. :)
my ecovacs just got this problem. great to have a very thorough tutorial on repairing the motor. I've pried open mine once, pretty much the same layout/construction.. I'll try to repair the wheel 👍👍
Good luck! Please feel free to comment with any questions you might have along the way.
@@AlsAutoandAppliance update! just completed my fix. it's successful 👍👍 so i can confirm, this tutorial is applicable to Ecovacs Deebot U2 Pro, albeit with some minor differences.. thanks mate for the video. 🙏👍
@@Deguile That’s great news! Great job on the fix and thank you for the update! 😃
Thank you very much :)
You're welcome!
Hi! Awesome video I was wondering how to get to the side brush. One side brush is loose...and it makes a weird noise while it's running.
Thanks for the video. My wheel motor stopped working. Before I desoldered it, I tried spraying canned air, WD-40, and DeoxIT D5 contact cleaner in the various holes on the side of the motor. I tapped the motor on my concrete floor to loosen things up inside, waited 10 minutes, and the motor started working again.
NICE! Combo percussive-chemical cleaning repair! Should do a video on that. ;^) Make sure and give us an update on how long your fix works.
Any idea what the cable that connects the wheel assembly to the main board is called? My wheel motor is fine but somehow the motor burned through the cable.
Thank you soo much! I fixed my issue (2 beeps red blinking LED) it turns out one of the bumpers was stuck. It was dirty inside and after a quick dusting it works again!
Awesome news! So glad the video helped! Happy New Year!
Is there another way to avoid disassembling the controller board over the step motor and test if motor run? Because I have the same problem and it the motor makes very little turns (I don't know if exists a problem with the controller) Thanks!
Thanks!
Thank you so much for your contribution! I hope you got your eufy back up and running!
Hey thanks for this. Mine does a similar thing and won’t go forward. I also get two beeps instead of the one you have which apparently is the front bumper. I’ve cleaned everything that can be cleaned without taking it completely appart which I’m now going to use your video to do :)
You might be able to just remove the bumper part to access the bumper switches and get those cleaned up. Sometimes a tiny bit of grease where the switches contact the main body is all that's needed to keep them from sticking. Some folks have removed material from the switches or the body to stop them from sticking. Let us know how it goes!
Do you have a fix for the Slim eufy 11S's under carrier swivel-roller not staying inside but drops out if when picking it up? Thank you so much for the great disassembly video. Much needed!
This is surprising to me. The axle should be snapped in pretty tight. Have you had to remove that wheel before? Is just the wheel coming out or the wheel plus the swivel part? Sorry for the late response.
Hi thank you for the link to your video, i tried this but unfortunately the motor is dead. I have looked online for parts but couldn't find any. Where can i get a motor from or the whole wheel assembly ? thank you
Ugh, so it looks like the brush and vacuum motors are available, but not the drive wheel motor. I just looked at one and there is no number stamped anywhere on the one for the wheel. I'll have to figure out what an equivalent replacement is. Right now, it's looking like it's an RS-365 dc motor. I'll get some measurements and hopefully narrow it down. With that said, all of the motors I've taken apart and cleaned were successfully revived. Did you take your motor apart and clean between the commutators?
what about 'the wheel overload' i have change the wheel and ita doesnt change the error,
Fantastic! I have exactly the same problem on my 30C robot and was trying to find a new motor after watching your video as it could be easier, but just noticed the comments that they are not available.. the robovac 30C has the circuit welded together to the motor, I will have to buy some tools to do it.. any tips? just to be careful? thank you for such a fantastic detailed video!!
Thank you for the compliment! To get the board off of the motor, you will need a soldering iron. They are pretty cheap and there are some good tutorials on soldering/de-soldering tecniques. You will also need a means to remove the solder once heated. This can be done with solder wick (braided copper ribbon that acts as a sponge) or a solder vacuum. I would buy the motors from the manufacturer in china, but the minimum quantity is 1000 pieces and I also would be a little bit worried with the current virus situation going on there. If you do decide to tackle repairing the motor and you get stuck, feel free to comment and myself or other viewers should be able to help. Good luck!
Wow. I think this is what's,wrong w my Goovi FOOC but there's no way I can go thru all of this to fix it. What Brand ( and model, if possible) is the most reliable robovac? I've got to have a robovac, cuz I have so many spine issues, I no longer can run a sweeper--upright, canister, or other. I don't need one that can mop or self empty. Just vacuum. I 'm just going for long term reliability! Please help. A reliable robovac is a must for me. Thx. Very excellent video here. You are an amazing communicator!!!
Thank you so much for the compliments! To answer your question on the recommended robovac...hands-down Roomba. Yes, they are expensive, but they work fantastic and parts are readily available and easy to work on. With that said, I still like eufy brand for affordability and decent reliability. Plus there are youtube vids on how to fix them, lol. :) Hope you are able to heal from your spine issues and thank you for commenting!
Hey--- thx for the reply & good wishes for my spinal health ❤
Hi, Thanks for the video I was able to follow it right through Awesome. I went through the cleanup procedure but unfortunately it didn't pass the battery test. Would love to get me hands on a replacement motor as I think it crazy that we have no support here in Canada. Would you please let me know if you find a motor that could be used and where to get one. I hate to throw out the unit and just buy another one. I'm trying to save our planet :) The company Ecovacs was totally useless and unapologetic about their lack of support. Many thanks again I'm you helped out a lot of people.
You are welcome. Unfortunately the only way to get replacement motors is to order 1000 of them from the manufacturer in China. You will either have to take the motor apart and attempt repair or take a leap of faith on a used one from ebay. :(
Great video, having trouble getting bumper back on. Help!
Sorry you are having troubles. The bumper can be pretty tricky to get aligned properly. The biggest problems I've come across are the bumper springs get bent during disassembly/reassembly, or the top and bottom half of eufy aren't closed together completely due to wires being pinched during reassambly. Take a look at those things and if all looks good, let me know and we'll try to figure out some other cause. Good luck!
Thanks for this helpful video. I am having a hard time putting the bumper back on. Do you have any tips?
The first thing is to make 100% sure the main body halves are closed together all the way. Sometime a wire or two can get pinched between the halves which leaves them so very slightly open. This makes the bumper feel tight after reinstalling. I install the bumper with the vacuum upright. Perfectly center the bumper then hang it off the main body. While holding the bumper in place, flip the vacuum over on its back then install the bottom piece. If you are still having a hard time, also check the bumper spring isn't bent or damaged. This can make installation difficult as well. Please comment back if you get the issue resolved and what you found the issue to be with installing the bumper. Good luck!
@@AlsAutoandAppliance Thank you for the tips. I had to push using strength and for several tries and now it is in place. It was not easy but finally it somehow got in!
I was getting four beeps with constant red light. I tried to clean the motor as explained in the video but the fault was not removed. Not sure if I did right or there is some other trouble shoot I need to address. Need help. Thanks
Hello. Have you seen this video: ruclips.net/video/Mo6kLUyUTKg/видео.html The four beeps can ALSO be caused by faulty corner brushes. If you get your eufy apart, unplug one corner brush motor at a time to see if the fault goes away. Also, if you unplug the brush motor, try to run it, and if it still has four beeps, then the problem is not with that brush. Let me know if you have any more questions.
Hi . Your video on fixing the wheel motor really helped me mix mine. Thank you so much for that. But now I have another problem with my Coredy r500. The main brush at the bottom is not spinning. Any suggestions how to get it fixed. Pls help
Did this happen after fixing the wheel motor or later? It's possible a connector is still unplugged. It could also be a broken or loose gear or belt in the transmission. If you open the bot back up, you should be able to observe the motor to see if it is spinning. If the motor doesn't run at all and it is plugged in, then I would suspect a bad motor. Let us know what you find. Here is a video that shows a brush transmission being checked: ruclips.net/video/Mo6kLUyUTKg/видео.html
@@AlsAutoandAppliance hi. No its not after fixing the wheel. It runs perfectly in mopping mode.
Hi, Thank you for the link. It did help me open up the motor. But the fault was in my transmission . The bearing was not at all moving. Anyways got it fixed. Thank you so much once again. 👍👍👍👍
Had the same issue on my 11s. Luckily I it has 4 screws that keeps the wheel assembly and didn't need to take the robot apart. As for the front window in my case was full of dust on the inside of the bumper that could be easily removed by some compressed air.
Excellent job!
I have the same issue as in the video. I purchased a replacement wheel and motor from eufy. It did not fix the problem, what else could be an issue? The wheel spins fine after using the spin test.
So sorry to hear the new motor didn't fix the issue. There's a chance the circuitry on your main board is damaged. Also, make sure the connector is plugged in securely. There's also a slim chance the new motor is bad. Something you can try is to plug the new and/or old motor into the connection for the side that works. You should be able to start up the vacuum and observe the wheels before it faults out for not detecting movement or the floor. Let us know what you find if you dive into the troubleshooting.
Hi! Do you recommend me to try this with an ecovacs Deebot m80 pro? It has started driving in circles and sending error message on the app "driving wheel malfunction"
Yes! While the construction of each manufacturer varies slightly from one another, they essentially all work in the same way with similar hardware. It's helpful if you take pictures along the way during disassembly to help put it back together when you are done. Better yet, take video and post it on youtube. :)
Thank you so much buddy!! My problem is mine beeps 3 times and shuts down on me! Any ideas?
What is the red light doing? Does it flash or is it steady?
does anyone have a link for replacement parts i need a brush motor
I'm working on getting replacement motors. Unfortunately, there are no substitutes, as these motors were made specifically for eufy. Right now, it's looking like it would be about $25 each. Trying to figure out the logistics of getting the parts here. In the mean-time, the only option is to take the motor apart to get it going.
I have literally the exact same issue with the wheel and brush like you show in this video. Would would say this is a design flaw? I have the 12 and it lasted 14 months until this problem happened. Wondering now if I should get a replacement wheel/motor or just buy a new one? :(
Yes, it is definitely a design flaw. They do sell replacement assemblies at eufy, although they don't advertise the website. I also have seen parts for sale on Amazon, but at a higher price. See this video for info: ruclips.net/video/zsihomMToE8/видео.html
@@AlsAutoandAppliance Thanks for your help and a great video.
I have a side brush that won't stop spinning unless I turn off the power button underneath, would this be a sign of a shorted motor or perhaps a pcb issue?
Once you turn the power switch back on, does it immediately start spinning again or do you have to start a cycle? If it spins no matter what, there could possibly be either a short in the wiring or a transistor on the main board could have failed "on".
@@AlsAutoandAppliance yes as soon as the power switch is on it starts spinning regardless of the status of the machine
@@JBTYpr have you opened up your vacuum yet? Look for wires that might be pinched or worn through. Also check the board around where the motor plugs into to see if there are any burned components. If it’s a bad transistor, there is usually a burned electrical smell associated with it.
@@AlsAutoandAppliance thanks for the help! i will update you when i do open it up
I'm going to try this on my robovac 11+ . Do you know where I can buy a replacement motor?
I'm working on finding out the right replacement motor to install for the wheels. It's looking like a RS-365 type motor. Will need to study the one from eufy to narrow down the exact model.
@@AlsAutoandAppliance Have you had any luck finding the right motor? I'm having exact same issue with my robovac 11+. I will appreciate any info you have.
Do you know why mine keeps bumping into walls as if it was blind? When I just turned it on, it works for like 15 seconds, changing direction before hitting the wall then proceeds to bump into walls again. It's also a Eufy Robovac 11.
You might have to remove the front bumper and clean off the window strip. The outside can get scratched up to the point where it either can't see or it thinks it sees an obstruction. Scratches can be polished out with plastic polish. The inside of the window will get dust accumulated and cause the same problems.
@@AlsAutoandAppliance Thank you for your reply, I have removed the front bumper like you have and there was a lot of dust cleaned off. However, the problem still persists and I have used Meguiar's Plastx for the front, I'm thinking I should buy a new one..
@@yoyosick1234 When it bumps into the wall, does it back up and turn or just keeps pushing on the wall? It's possible the bumper switch isn't working. Also, make sure the bumper connector is plugged in and the bumper moves freely and springs back out after being depressed.
@@AlsAutoandAppliance It bumps into the wall full speed and turns away, but it should be slowing down as it approaches the wall and turns before hitting it. After removing the front bumper, I did properly plug in the bumper connector and it moves freely and springs back. I'm guessing the front bumper is just way too scratched for the IR to detect walls.
My Eufy Robovac 11s us stuck on charging station... If I press start button using remote or on the robot its beeps once and stays there... no movement at all... any guess what could have gone wrong?
Does it do the same thing if not on the charger dock?
@@AlsAutoandAppliance no, if its not on the charging station then its a dead fish. I have uploaded the video here vimeo.com/user101698661/review/353129068/636648f6f9
Guys anyone has any clue of what the issue is... Does it look like a battery issue?
it is fairly easy until 20:15 I can't open the motor, it's very tight. do you have any suggestion? THanks a lot for your video anyway!
I was thinking about trying this myself, but you could remove the tabs using a dremel tool then use solder in place of the missing tabs when reassembling. Super glue could possibly work as well as products like JB Weld.
At 18:20 I paused the video and ordered a left wheel assembly from Amazon. Great video nonetheless.
Hi, I love your video, I did the whole process, and the wheel came back to life. I do have a problem that it is continually working backwards after the repair. The wheels are spinning in same direction but the robot is going backwards. Have I done something wrong when reconnecting the wires? Is that possible as all of them are going in the same connection? Thank you.
Hello, and thank you for visiting! Sorry to hear you are still having issues with your vac. One thing that could happen during this repair is the brush assembly being installed 180 degrees from where it should be. This would have the same effect as soldering the motor back to the feedback board 180 degrees off. Did you repair just one wheel? You can try to unsolder the motor from the board and rotate and re-solder 180 degrees out and see if that remedies anything. Also, make sure there are no broken or pinched wired from the bumper. If you removed the main board, there is a good chance the front sensors got bent when reinstalling the board to the chassis. I know it's a pain, but it would be a good idea to take the robot back apart and just have a look at everything again. Let us know what you find and good luck!
Amazing, thank you for your support, i actualy have made a mistake that I’ve put the motor 180 degrees in wrong place. I’ve took it all out and changed and resolver the board. I did this only on my left wheel. Now when I’ve put it together he doesn’t want to start as he thinks he is off the floor, and I keep on getting the same message, and can’t get it back to life? Have I done something wrong? I’m so confused right now. The only thing that I can think of is that board is maybe solder under the really small angle, but the wheel on it was spinning very well. Thank you for your previous reply and I hope you could help me once again. 🙏
I figured it out, one of the cables that was connected to the board was not fully inside! Someone wrote here, thanks god for Internet, I can’t agree more, thank you for your support, my vacuum is working perfectly now!!!
@@milosmisic8936 That is awesome to hear! Congrats! :) Incidentally, ours decided to end it's career by driving off the end of the stairs and bouncing all the way to the bottom. Now it's faulting for drop sensor. I guess there will be a new video soon, lol.
Random question, could I possibly send mine into you to get fixed?
So sorry for the late reply. What issue are you having with yours?
Hey there, thanks for another excellent tutorial for those of us in Anker's planned obsolescence hell! I love my 3 Robovacs, but something this expensive should last for years, not 13 months. Anyway, I've been toiling away working on 3D printing replacement gears for the side brushes, I've had 3 failed assemblies so far. Finally may have a working version, got it back together and it runs great for two full runs, but it can't find home anymore. It is such a hassle to disassemble again I'm inclined to wait a bit and see how my gears hold up, but does anyone have any ideas for how I might have messed up the homing sensor? I can't find any documentation anywhere (including your videos) that names or locates the home sensor. Maybe I disconnected or pinched something, but it would help to know where to look when I open it up again.
The sensors in the very front are how it locates home. Those sensors are also the ones most prone to getting bent while disassembling and reassembling the board into the body shell. If you remove just the bumper, you should see the sensors in question. Worst case, you won't see them and they are completely bent up under the board. If they are visible, they should be facing straight forward. If they look like they are bent in any direction other than forward, carefully straighten them out. Another thing that can happen is the IR sensor window strip that goes across the bumper can get lots of dust built up on the inside and/or the front side can get scratched up and the vac becomes "blind". You can use a plastic polish to get the scratches out. Hope this helps and let us know how things go.
@@AlsAutoandAppliance Thanks for sharing! I took off the bumper, and don't see any sensors. It was also dirty inside, so I cleaned up and tried again. Still erratic homing behavior. I found another of your videos where I think you showed the sensors (here: i.imgur.com/I2Gsz6N.png ), and I guess I need to do a full teardown again to see if I bent one or both of them out of position, I expect that's the problem. Sure wish a full teardown set of photos with labels existed somewhere, really unhappy with Anker for this bad attitude about support, I updated my Amazon review to reflect this and encourage everyone else to do so, Anker will only respond to pressure on future sales.
@@scottbierly3398 Thank you for that image. Those are definitely the sensors to be looking for. Definitely get it all the way opened up again to verify they are tucked into their pockets. Unfortunately, most tech companies don't want you to be able to fix their things when they break. There is a term you might be familiar with called "engineered failure". Designers purposefully use less robust parts to keep their products from lasting forever. The stuff they make money on is partially the product its self, but largely on replacement consumable parts such as brushes and filters. I think the parts website wasn't supposed to be found, lol. Good luck on giving yours it's sight back. :)
@@AlsAutoandAppliance Well, that did the trick, she effortlessly found the home charger now that I fixed those sensors. I was super non-obvious when I was reassembling. I had done it 3 times before, always easy, but that time nothing would go flush, and I had to use some force (always a bad sign) to make it fit. In doing so, I literally bent both sensors legs 90 degrees so they were nearly blind, I don't know how it could see at all! And yes, once you know they are there, you can see how they tuck into their cavities when done properly, nothing complicated. My bad news is, one of my 3D printed gears failed after just 4 days, the tiny gear broke off of it's base part (the smaller double gear). Sigh. I worked very hard to get Nylon to print new gears within mechanical tolerances to function, but the layers delaminated. I might have to place an order to China to get some in the pipeline for future failures, sadly. Thanks for your help!
@@scottbierly3398 Awesome! Glad you got it figured out! On the gears, have you tried PLA, just for grins? Otherwise, check your locality for a makerspace that has resin 3D printers or a polyjet printer.
So eufy and ECOVAC is the same ?
Several "clone" robot vacuums share many parts. it's hard to say which parts are compatible with which models, though. I only have eufy vacs. It's best to look up parts on ebay and compare yours to what is on there. Sorry not much help. :(
alsautoandappliance the same size same sound same wheels.
This is great! I hit an issue when I reassembled the wheel mount- While the motor works, the gears make a tremendous amount of noise and I can't figure out where it went wrong. Taking a gear out produces no noise when I spin the wheel and when I test the motor with the 9v, there is no noise. When its all together, its hard to push the wheel backwards, but forward is easy (but loud). Any idea where I could have gone wrong?
Check to make sure the gear on the motor is not pushed on too far on the shaft or too far out on the shaft. There should only be a very slight gap between the gear and the motor. I business card should slide in easily. I found that the wheels/brushes being easy to turn one way but not the other is normal. If it is hard to turn in both directions, it's likely a bad motor. Could also clean all the lube off and reapply some light grease. Otherwise, if it runs fine the way it is, it will probably be ok. Hope this helps!
@@AlsAutoandApplianceJust double checked all of it and changing the position helped a tiny bit. However, I agree that its the small gear that attaches directly to the motor spindle thats the issue. I swapped it with the opposite wheel and just like that, no issue! It appears I may have damaged the gear when I removed it. Any idea the measurements on this gear? Going to see if I can locate a replacement of sorts.
I was going to try it but dropped it problem fixed lol
That is what we call in the repair industry "percussive maintenance". This is usually done with a very large hammer. :) Glad you're back up and running!
@@AlsAutoandAppliance lol yes thank you its working like new
Hi! My Eufy Robovac 11 seems to have lost its mind. 🤨 It took a quick turn into disfunctionality. When my wife said it stopped working I took a look at it. At that point it wouldn't respond to the remote control, and it didn't respond to the switch button on the unit itself either. When it set it on the charging stand and switched it on, the light changed from blue to red and back again flashing and beeping at the same time.
I charged the battery directly by plugging the cord into the unit. When fully charged when I turned it on it would only go forward, driven by the brush only as the drive wheels don't move at all. I noticed that when I turned it on when I held it upside down, rocking out left and right would cause functions to change sporadically for a while, but then made no difference whatever. I took it apart and everything looks good, but it is definitely not working. It seems to be a computer problem.
I called the tech support line and they said to "recycle it" and but a replacement unit. After only 18 months I'm not happy about that, and wonder if you have any ideas?
Thanks very much,
Dick Funnell
Tech support is such a misleading title these days. Sorry to hear your eufy is sick. From your description, it sounds like there is something loose inside or there are loose connections. I know you already opened it up to take a look, but did you unplug all of the connectors and plug them back in? Also try to disconnect the battery for a while to then plug everything back in. If it still acts goofy, try unplugging one thing at a time to see if it is a bad sensor or motor causing issues. Did the unit ever get wet by chance?
alsautoandappliance, Thanks very much for the feedback!
No, the machine is never gotten wet. I did disconnect The battery for about half an hour and plugged it back in hoping something would reset but no such luck. I didn’t try it with anything unplugged, although I did try to unplug a couple of the connectors but they were quite tight so I left them as they were. I recently had a bad experience with a tiny connector on the motherboard of my old MacBook Pro, so I was a little bit wary. I did notice in your video that you used a pair of needle nose pliers to get some of the connectors off, so I’ll be a little bolder with this and try again. Sounds like A good idea to disconnect everything and leave it that way, and then plug things in again and see how it goes. Thanks for the tip, I’ll keep you posted when I get a chance to dip into it again. Blessings from Wales!
Hi man I can't do all this shite I'm going 2 give it 2 recical and never buy 1 again
Sorry you were not successful, but hope you were able to learn what goes on inside these things. If you are stuck and want to keep trying, feel free to comment with any questions. There are also a handful of replacement parts available for some models too.
Thanks a lot at first. I am experiencing an issue with the 360 s7 where the main brush is not turning (or very slow for a short time in the beginning). Gearbox is very fine and when I connect the motor directly to the battery it spins like crazy. But when its powered through the robot, it spins very slowly and stops after a short time. The main Brush seems to be veeery similar to the one you have on the eufy. I have gathered some footage of the issue: ruclips.net/video/_vACuYwZ7as/видео.html Maybe you can help
If the motor runs fine when powered directly from the battery, it definitely sounds like a drive circuit issue. Are you powering it through the motor cables or directly to the terminals on the motor? There is usually a motor control board soldered to the motor. Has 360 responded to you if you've reached out to them? I wonder if there could be a sensor malfunction that is causing the robot to slow and stop the brush. That was a good idea to post the video of the issue. Sorry I couldn't be more helpful. :(
@@AlsAutoandAppliance i connected the Battery for a short moment directly to the terminals of the motor. Idon't know what any of the control boards do so i didn't want to accidently fry the electronics by applying direct battery voltage to a circuit board. If you are interested in investigating the issue we can get in touch via another medium than the youtube comment section! :)
360 hasn't responded yet but I've just messaged then this weekend.
anyways thanks a lot so far!
I have Updates: 360 support on Facebook connected me with a Company called amberwiser. they seem to handle some of the logistics for 360... Not really transparent. They've concluded it's a motor issue and decided to send me a new main brush module (with new motor I assume) even after I told them I doubt it's due to the motor and them asking an engineer. Some time after that I got my answer from a 360 email adress (after to many weeks of waiting). They said it's a driver issue and will be sending a new driver board. I have no idea when and what will reach my postbox but I'll keep you posted with the progress. I am upset I can't repair it by myself. Would love to understand the details of the driver board.
@@adressegrandbizarre852 Thank you so much for posting this update. It's great that they are willing to send you parts (hope it's the motor AND board!). If they aren't asking for the old parts back, it would be a good opportunity to do some diagnostic checks on the components. Definitely keep everyone in the loop on your progress!
Finally there is an answer: It really was this the small board. the small circuit board with capacitors, transistors and stuff, that is connected by only two wires (ground and current) to the mainboard and on the other side connects the same two wires to the main brush motor. This piece is replaced and now everything is working.
After all this time I've received the board yesterday, but only the board. It was free of charge though. The Main brush is now spinning. I have no Idea what the board does, but it was obviously broken.
There seem to be also other versions of the board with less electronics as this chinese teardown portrays. zhuanlan.zhihu.com/p/86223111
Unfortunately I couldn't get an explenation after all this time from 360 since I never got in touch with someone who could tell me.
No Idea why it is so complex, but maybe it shuts down the motor if it draws to much current (when it cant spin maybe), or it does some of the carpet detection (and increasing suction) stuff. The latter I can not confirm since I haven't got it working. The robot doesn't increase suction on carpets. Maybe it's just to stupid for that.
Hi, can you help me fix this error: ruclips.net/video/YVSuKv2rXE4/видео.html. I also replaced the fan motor but with no luck. The model is BlitzWolf® BW-VC1.
Sorry to hear you are having issues with your blitzwolf. I don't know if it's the video, but it sounds like there are bad bearings or the vacuum motor rubbing on something. When you say you replaced the fan motor, was that with a new unit or used? Also, did the replacement unit come with the fan installed or did you have to swap it?
