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

[@Ed-yj8ts]

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.

[@timothyerickson89]

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.

[@StezStixFix]

Thanks Timothy. That's a very good call with the magnet! And always good practice to keep the screws organised. Really appreciate the feedback and kind words. Thank you. 👍

[@arrsventing]

Quick pointer. You can magnetise your screwdrivers by stroking a magnet along its length. The more you do this the more powerful the magnetism.

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.

[@StezStixFix]

Thanks E! Much appreciated 👍

[@scottgriffith1774]

So the tutorial is spot on, even got mine back together and it worked but...... 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....

[@StezStixFix]

Hi Scott. Yeah, it does seem to be quite common, and I'm sure there are people out there that are just 3D printing these cogs and selling them on eBay. In which case, they are not gonna last.

[@vBDKv]

I only run my 11s on hardwood floors, and I've had 2 robots strip their gears. The first after 6 months, the replacement after 4 months. They are trash robot vacuums.

[@smuggridge]

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.

[@StezStixFix]

Glad it helped! Thank you 👍

[@ulfkirsten8017]

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)

Hello, friend, and my motherboard broke on the QUFY RoboVac 35C robot vacuum cleaner. Can you tell me how to find her, please, thank you very much.I just wanted to ask, let's say the board has its own code, do you remember it or do you have it somewhere?

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

Hi Roy. I would imagine that you've lost a tooth or teeth in one of the gears, so it's catching some of the time and slipping the rest. 👍

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.

[@StezStixFix]

Hi Cody! Glad it's working. Yeah, I think you've likely knocked an IR sensor while putting it back together. Probably worth checking it out! Also just make sure they're clean while you're at it. Good luck 👍

[@mick0905]

Pay close attention to 12:43 those are the sensors the Eufy uses to find its way home and its very easy to accidentally fold them under the board rather than seating them into the slots in the bumper.

Hi Steve, since following this video I'm now getting the 2 beep error - "side brush stuck" even though it moves freely. And I also can't get the bumper on properly.

[@tombrizzi8904]

Suggestion - please edit your video and add a step removing the battery from the vaccuum. Even with the power switch on the bottom turned off and unplugging the power button on the cover, there is still power going to the circuit board. In the step to remove the 3 screws to move the circuit board slightly, one of the silver screws landed on the circuit board, sparked and created an electro-magnetic charge holding the screw to the two contacts shorting. Pulled it off quickly, and removed the battery for the rest of the steps, but after replacing the side brush gears and reassembling, my vaccuum just beeps constantly as soon as the main power switch on the bottom of the vaccum is turned on. Most of us DYI's that have had ours long enough to replace the gears are already familar with how easy and quick it is to remove the battery when doing this repair. Time for a new robo-vac.

Nvm got it sorted, the connector had come loose from a sensor ON THE SENSOR SIDE, which made it very difficult to spot, but figured it out after several tries.

[@StezStixFix]

Thanks Yanksguy, sorry about that, it really wasn't deliberate. If I remember rightly, the most important part of that is to get the springs aligned at the front - if they slip under the bumper, then it can be difficult to get it back on. I'd suggest taking your time and trying to align everything up. Once you have the knack, it's usually pretty straightforward. I hope you manage it! Good luck 👍

Nice tutorial. Up until the front bumper install. It definitely is not that easy. Been trying for 45 minutes....

@@StezStixFix Sorry mate. If the 2 springs are pushed in the bumper doesn't spring back. It almost seems as though the tabs are supposed to go together on the top but then it is also to tight. I have been trying for 90 minutes now. There is something missing when you are describing disassembly. Wish I had another go at it when taking it apart. I would definitely pay more attention to how it was together. Now I am out the cost of 2 sets of gears. Love the vacuum so much I am trying a second. Nice video but again it definitely needs more.

I'm not really sure what to say. It's really hard to help you without seeing it, but sounds like something has gone wrong. It can take a few tries, but certainly shouldn't take that long.
