Thanks for the advise but that was 2 years ago! I get where your coming from but I accept it could be out a little but dare say I don't think its more than +/- 5% at worse. But like you say can't know for sure unless I get it certified. Not gonna happen for quick test for measuring round about figures for a home test environment. To me the nominal power it draws vs litres per minute seem to line up with the pressure I measured with the cheap amazon gauge. The 3 all line up pretty close . If 1 of the 3 was off then I could blame a faulty cheap amp/watt meter or the cheap amazon pressure gauge or the bathroom scale. It's a simple test that I did with what I had with no money or sponsors or donations. Happy to send you the gauge if you like, only used it for that 1 off test 2 years ago. Wouldn't surprise me if its internals are corroded by now but if you can verify it at your cost then I'm happy to send it to you if postage is not too expensive!

@@Eye-1-70 appreciated. Thanks for your support

All these manufacturers love to only mention the "max pressure", but the devices are never able to reach that pressure. They should be obligated to mention the "working pressure", but you can only find these in the small prints. The "working pressure" is the realistic pressure. For the Karcher K7: the working pressure is 160 bar (16 mpa) 180 bar (18 mpa) is pure marketing. For the Ava P80: the working pressure is 130 bar (13 mpa) 160 bar (16 mpa) is pure marketing.

Been a while now and probably time I redo my paths and driveway again. But I think when I used to do it would take me around 5 to 6 hours and if I went any faster it would leave lines . With the Karcher K7 paired with the Tracer 7 I think I can happily say its halved that time with a more even result. If I want to get better and faster result then there is nothing really that's electric that can. So in order to go the next step then it has to be petrol powered and thats too noisy and too heavy for my back right now..... oh previous was the Aldi branded one and the top of the line Jet-USA 3500psi which turned out the cheap Aldi was more powerful than the JET Usa. I complained and told them my findings and that they were not as per label. They asked for me to return the unit for testing. Next day no result, instead they reversed my payment immediately and said nothing of their testing results. Basically they did that to shut me up and get the unit from me before I could test like I did the K7. So don't buy a Jet Usa because the claim nominal 2500psi @ 6.8l ..... unless I had a really bad unit it wasn't even close! Anyway that was a long time ago, maybe now they have gotten better

@@SamFerlauto thanks Sam, great info. I hope to upgrade my K2 to a K7 soon

Wow how time flys.... been almost 2 years now. Memory is a little foggy but as said at around the 1 minute mark the MAX rating of any pressure washer should NOT be believed on any pressure washer, it is most likely the pressure of peak intermittent spikes it could possibly handle from time to time! When ever you look at pressure washers you need to get the nominal rating which on this unit is 13MPa (around 1885psi). Think of it like this , lets say your car can rev a maximum of 8000rpm but what happens if you hit that peak for long periods of time? kaboom! just because its rated at 16MPa MAX doesn't mean you should! hope that makes sense. In any case when looking to buy NEVER fixate on the MAX rating (That's the sales mumbo-jumbo to suck you in ) instead look at the lower figure ALWAYS as that should be the nominal running it can handle constantly. So the aim of this video is simple. It is to test the unit for nominal PSI vs kW vs Q as stated on the label . It states nominal rating of 13MPa@2.2kW and at that rating it should pump out 8.2L/min so therefore I conclude that it does that. I get that my test were not lab quality precise but neither are the nozzles, eg: a blue nozzle from amazon vs a quality brand will give you different readings, so in short nothing is perfect. If the power at your house is 240Vac and the power at my house is 230Vac the results will not be the same but nominally it will be close. So in reality, if you try to understand in what I consider "the holy trinity" of nominal PSI/Kw/Q ratings of pressure washers you should be able look at any pressure washer and with the perfect nozzle size be able to achieve those nominal ratings that are stated on the label. Hope that has made it clearer for you.

Hey thanks for commenting and yes your right I didn't weigh the bucket. It was around 750gr. Couple of points though 1. hard to see on the video but a lot of water was splashing out as well so probably lost 200 or so grams there. So I would say around all up your looking at around 7.6lpm at 1850PSI 2. Yes I used a tip that doesn't come with the unit to reach the nominated pressure, amperage and kW rating, but how else can you test the nominal ratings? In a perfect world where I had all the time in the world and I wasn't recoving of a back injury I would probably make a followup video. But no one is paying me to test it and this video was simply to show my quick findings and to get it to close to the nominal ratings. Anyway the unit I have is still going and still doing a decent job. Maybe when it dies I'll buy an Ozito and test that out for you!

Not sure what you mean.

Karcher k2 1250psi @ 4.07lpm K3 1500psi @ 4.4lpm K4 and k5 are the same 1400psi @4.4lpm K7 1600 psi @ approx 6-7lpm

Lol I was obviously bored during covid!

Lol just living the dream. This is exactly how to make stuff unsexy!

Very true.

This is definitely late, but if you choose an karcher professional pressure washer they have brass parts too, and some saw that they have ceramic coated stainless steel

I bought this and replaced everything but the body. It has a better hose, a better gun and brass quick connections.

No but maybe later on today I might need to go buy some cement!. Found my mains water pipe burst under my slab so gonna be one of those days. Spent all morning cutting away the concrete so plumber can do his thing. Hopefully he turns up today!

Hey thank you for your comment hope you enjoyed the review and thankfully the clip stopped before the sheets dropped!

Lol everyone love bunnings! Thanks for the support.

Yeah it's a good little unit. The packing up gets a tedious as the hose n cord wrap around the unit but other than I find the compact size when packed away a bigger advantage

@@SamFerlauto yeah ordered one last night from Supercheap Auto and they will deliver on Friday as they had none in stock!

@@Milele good on you. I'm just bought the T7 T-racer this morning. Putting video together on that hopefully today. So stay tuned

@@SamFerlauto can’t wait to see the video and demonstration!

@@Milele It's done and now up. Enjoy ruclips.net/video/FGUCcLrbvO0/видео.html

Any advice on how to wind up the hose after use. It has a mind of its own.

@@spmck6526 lay it out straight then coil it up , that's what I do, it works fine

I've not tried running without a hose in the past but yes this will be normal as I have just removed my quick connector and can look through it... so there is no valve so therefore when the hose is not connected and the tap is on you will have water coming out of the quick connector.

@@SamFerlauto that's true. I've just look with a flashlight and it doesn't have any valve in there, it's just a clear hole. I was not sure if it has to shoot water from there if the gun is unplugged with the water hose on. I was really worried because I left the k7 in my workshop till now and the temperature was near to 0 degrees celsius. Today a took it home in the boiler room. Sorry for my english. Thanks a lot. Wish you a happy new year and good luck! 🥂

@@calinsandor9518 thank you. Hope you get nice goodies from Santa! Your English is perfect no need to apologise!

Sorry but I have only tested this one. For washing a car a 40degree tip at around 1000psi is ideal from what I have seen from other car detailed video's.

Your welcome. Thanks for the feedback.

I don't understand the question but it connects to the outlet of the stand Juwel Rio pump

Do you think this add attachment helps clear up the Walter better.

Thank you

Hey James. I'm by no means no expert on various pressure washers and haven't used the K7 for a while, but can say that I don't recall a hiss when letting go of the trigger. It could be possible that maybe a valve might be stuck open by either dirt or debree that could have come through the water line or metal debree from the manufacturing process. This could explain less pressure that is allowed to build up and the hiss could be the back flowing pressure bleeding back. If possible you should take it back and get another unit or get Karcher to check it out. So but currently travelling so I can't even confirm if the hissing happens on mine

I looked online for a standard T300 Tracer and it is the standard Karcher attachment so I would say 99.9% yes its the same and should seal and fit correctly

@@SamFerlauto Thank you.

The test was simply to validate the spec sheet. Now that it can supply the correct psi and litres per minute if you play with different nozzle orifices to match. The Turbo lance is really good and it blasts very well but the variable lance is ok cranked up but not as good as a tuned tip with a smaller orifice. Also I did pair it up with a Ryobi patio cleaner which gave me great results and much faster in completing the job BUT was a real pain to find all sorts of attachments to attach it with no leaks. Unfortunately it hasn't stopped raining here almost every weekend since I made the video and not gonna be sunny anytime soon! I want to buy a T7 and do away with all the attachments and see if I can get it to perform like the cheap Ryobi patio cleaner but until I get good weather that ain't happening!

You say they are crappy but I’m not happy with Karacher as my first K7 compact from 12 years ago lasted 10 years and the latest one managed 2 years and died, Karcher will not help or diagnose the problem by calling their support. I used mine very lightly as well, cleaning the car in the sumner maybe every fortnight and 2-3 other times for patio or other things. A repair centre cost is more than half of the price of the machine and that’s before any parts might be needed. I will not be buying any more from them.

@@Pain4yourmind Where are you? In the UK they have a 3 year warranty.

Thank you. They are still growing and varying between 2 to 4cm. Strange how some juststay soooo small while others thrive!

@@SamFerlauto Got eggs arriving tomorrow. bit nervous. ;-/

They are very very tolerant. You'll be fine

Thanks for your support. You won't regret it. The unit is good and so far so good

No sorry I removed because it was a hit n miss for most people to make it work but my new design is foolproof and as long as it prints properly works much much better FINAL 3D PRINTABLE DESIGN DOWNLOAD cults3d.com/en/3d-model/home/juwel-bioflow-filter-aerator-nozzle see the video here for this new model ruclips.net/video/Ji2P_MH4WLQ/видео.html and the final design video here ruclips.net/video/PEV118DwGBk/видео.html
