HOW TO replace the EUFY Robovac side brush motor gears | Repair kit from eBay | Teardown & Fit

EDIT: People have been asking me for the link to these. The ones I bought are no longer for sale from that seller, but I would suggest doing an eBay search for "eufy sidebrush gear" and you'll see the current ones available. 👍

In this video, I'm going to show you how easy it is to replace the gears in a Eufy Robovac side brush motor. This is useful for when your Robovac makes a clicking or ratcheting noise during operation.

You will need a Philips head screwdriver to take the Robovac apart and a toothpick (or cotton bud/q-tip) to apply the supplied grease.

This kit is suitable for the Robovac 11, 11C, 11S, 15C and 30C.

I found this very simple, but if you have any questions or comments, please detail them down below!

Thanks for watching!

Man! Your video saved me. I struggled getting the last parts back on until you explained that the PC board needed to capture the two sensor. Aha !! Thanks so much.

Very nicely made video. Clear, organized and accurate. I used a weekly pill organizer to temporarily save the 7 distinct screw types used to assemble this portion of my EUFY 11S, and a rare earth magnet stuck on my screwdriver to help extract the screws embedded deep in the plastic body parts.

Eufy has a video for how to replace the motor on their website. It is horrible. This is so much better. It's great to know i can just replace the gears next time.

Really helpful video, and very easy to follow. Mine failed in this way, but Eufy replaced it under the warranty with a refurb unit - that died within the year, but I was able to salvage the parts from it to fix the original! Many thanks.

So the tutorial is spot on, even got mine back together and it worked finding a quality replacement may be the biggest problem. Got mine off an Ebay site everything fit right but by day 2 all the teeth had stripped out. Honestly it worked better when the left side turned 25% of the time now the left side is dead. I think the eufy would be fine for hardwood floors only. They replaced the left side once and so did I so have to believe its a design flaw. Buyer beware....

Excellent video! Found gears from eBay seller, but for only $4US more Amazon had complete motor. Worth it to save some work I think, and still use your video, cheers!

Great video. Really helpful reference as I repaired my side brush this morning. Working again now. Thanks!

[PopVtecZ]

Great tutorial! Mine seems to be making a bit of noise on side more than the other, going to have to order a replacement here soon

Does anyone have a link for buying the part?

[LarryHopper]

Thank you for a very well done video. Is the 25C radically different? I cannot find replacement gears for the 25C.

[JohnSeto]

Thanks for this, I have the exact problem. Time to order the gear kit and try and replace them.Had a problem with the Robovac shutting down mid clean, contacting EUFY all they could offer me was a discount on a new one no repair or spare parts (I assume this will change next year with right to repair) turns out it was the battery, so I bought a 3rd party one from Amazon

I mean. It’s easy-ish. I wouldn’t have known where to start. Nice video!

I have a very cheap cleaner named "ONSON" and it looks 100% like this one. I think I paid €120 for it and it still makes a good job. It seems to be a really good Robovac clone! Can't wait to have a reason to take it apart so I can have an even closer look.
It only has some trouble with the main brush slot... or socket or whatever you wanna call it. The brush has too much space in the "passive" side of the socket that is not directly driven. It also makes a terrible noise but I just wrapped it in some aluminum foil on the end of the shaft and it works like a charm (it grinds away some aluminum... meh)

One of the side brushes stops intermittently! Any suggestions?

[fallg]

Great video - just fixed mine following these steps, thanks!

[kubave]

The MOST important question is not being answered: where did you purchase the replacement gears???

[gwendolynsmith]

Great video! How can I find this repair kit? Could you send the link please?

[jennymarie]

:) Thank you this was good, one question when I replaced the motor now my Eufy it's saying that it can't reverse, what do you think might be the problem now? :(

[codycannaday]

Replacement side brush motor is working perfectly now! However my 30C will no longer dock itself for charging. It take the wrong angle and make a ton of noise while struggling to get on the charging contacts. Any thoughts on what could have gone wrong? Thought It had something to do with the IR lights on the front but being misaligned but can’t be sure. Any help or guidance would be appreciated.
