Please contact me with any problems. Upgraded version with a bigger stronger spur gear. Eufy Robovac 11S 11SMAX 15T 30 30C 15C 12 35C side brush gear replacement. A common issue with these Eufy robovacs is that the gears end up stripping a few teeth which results in improper spinning of the brush motor. You will receive 2 gears which will fix one motor only, the gears are made from a high quality resin which is strong yet less brittle than the originals.
I fixed my own Eufy vac one with one these so thought I'd produce more to help you fix yours. These are completely my own design, and after spending hours on designing them in CAD and dozens of iterations I've hopefully made a set that will last longer than the originals. You'll need to swap both of these cogs as they were designed together and have a helical gear tooth which should make them quieter too. I'll pre-grease them with a bit of silicone grease or spray but you may need a touch more.
