Roomba Side Brush Stripped Threads Hack

If the retainer screw in your Roomba side brush module will no longer hold in the small nylon motor shaft because the threads are stripped, here is a simple solution that sidesteps the real issues and allows you to continue to use the motor module as long as it will turn properly.

You rock dave - I just avoided having to buy an entirely new motor module. Thank you!

[@doktorfixit]

Many thanks for the kind words. Fixin' is better than replacin' any day...

The white plastic hexagon piece is shredded on my robot, will it still work if I follow the video or do I need to replace the motor?

[@martyspittler3581]

Glues fail on the nylon gear post plus the screw threads are inadequate.
Dave does nice work-i just used my hand drill and pinned it.

Thanks, Marty, for the kind words. I am truly glad you did that with a hand drill. I probably over-engineer things on occasion.

It baffles me that they made this obvious design mistake, hopefully it's fixed for future models

Hi Chris, Yes, I can think of at least three ways they could have made that side brush better to change out. The cynical view is that they wanted to sell more modules, not just replacement brushes.

Its sad what a terrible design this is. I think I replaced the side brush motor like 8 times now. I wish someone sold one that is brass! Recently I got a new rug and the side brush motor gets stripped on this new rug within one cleaning (the brush goes slightly under the rug). I was about to buy an Eufy vacuum when I came across this video. I did what you said and so far so good (30 minutes in), but we will see how the next week looks. Thanks for the tip I am not very handy, but was able to pull this off just with a drill. The hardest part was finding a paper clip!

[@doktorfixit]

Thanks for feedback. You just proved that you are pretty handy. I posted this video almost 18 months ago and my wife has been changing those brushes ever since. She tells me that "the fix" is still working and will let me know when she needs some more brushes.
