Eufy noisey

After reading the the tips about the drive end of the roller bar. I went and got the hot glue gun and put a dab of hot glue into the female end housing and immediately inset the male drive end into the square drive. Vola no more noise and a sweet sounding RoboVac 30.
Make sure you don’t put to much glue as it will push out onto the housing and the end of the roller bar which will cause drag and the drive motor will shut downs it will be working to hard.
You then need to dig out the cold glue and put in a smaller amount.
We are going to order a new roller bar but untill it arrives this works great and the noise isn’t causing us to resent our dependable robot LOL.

I am also having a problem with noise with my Eufy Robovac 11. I’m relatively certain that the origin of the noise is the rotating side sweepers, not the central one, and was wondering if there was any advice about how to disassemble these and remove any debris that might be causing the problem. Thanks!

You find excellent videos showing you how to disassemble such a roboVac.
Give it a try.

Outstanding solution! Thanks alot! The noise was driving us nuts to the point of scrapping it. I tried all the other solutions but this was the answer. Duct tape strikes again! :O)

Mine has the same noise. Sent them a video to show them as they requested. Not impressed. this clearly is a design issue and we should not have to buy a new brush, or stick duct tape over the end. I am in the UK and I found their service not great. Had to chase them. I have decided to scrap mine. Waste of money.

You will really give the Robo to the garbage?
There might be many in UK would would like to use it for spare parts.
Too bad I am in DE, the sending cost are too high! :wink:

Hi can anyone please show me with pictures how you used tape to fix the problem or any other solutions as the noise is doing my head in

Also had the same noise problem described, essentially a loud rattling noise emanating from the brush area. On carpet: no noise. Brush removed: no noise. Brush is clean.
Ended up wrapping one layer of masking tape around the square alignment ‘pin’ on the one end of the brush. Reinstalling the brush gave a more positive, solid feel, and no noise. I suspect the masking tape won’t last long, but as a way to isolate the problem I can now look for a more permanent solution. I like the hot glue idea that someone posted. Will try that when the tape fails.

Made an account just to thank you. I was going crazy trying to figure this out. Thanks a lot.

Would you mind showing some pictures of which panels you’re talking about removing? It seems like a very good diagnostic fix.

Our 2+ year old 11s still functions great (amazing runtime, I wish iPhone batteries lasted so long!) but had developed a horrible rattle.
So glad I found this discussion because it was the central rotating brush. Not sure if it being an off-brand replacement (our third one in two years) was the cause but after reading these comments the diagnosis and fix were simple and cheap. I just looped a rubber band tight around the square side of the rotating brush and fit it into the socket and our strong and silent friend is back!
Thanks to everyone who figured this out and shared their fixes!

My mind is blown. I took the brush out and no more clicking, put some tape on (round part), put the brush back and no more clicking. THANK YOU

This is just crazy, I’ve lived with that clicking for 3 months. I’ve done deep cleans and taken sober of the casing off and cleaned. My next step was to really take it apart.

August, 2020 - We own Eufy 15C Max. Had same issue. Called Eufy support. They suggested to remove the long roller (that we clean everyday) and run Eufy without it. If the sound is gone, just replace the brush. (It was gone for us - a new roller FIXED it). Support guy said we typically need to replace the Roller Brush every 6 months. (By the way, if that did not fix it, then he said there is something stuck in the internal motor - I have no idea what fixing that would involve.) Anyway, if you already tried what fixed it for us, then call Eufy support (800 number on back of device) - they were very helpful.

De nada! :smiley:

For my Eufy 11S it was clogged up roller bearing. I took the cap off with pliers and cleaned out an insane amount of hair wrapped up in there (2 dog household). I did pry the bearing out from the roller just a bit.

ja this wheel really should spin freely!

Easy fix for this. Throw it away and buy another brand. I called Eufy for the extremely loud rattle and they offered me a discount on a new vacuum. No Thanks. I’m not going to buy a new vacuum every other year when it fails. It was out of warranty. The plastic piece that holds the roller seems to be the issue. Eufy told me that the engineers would not fix the problem because everyone would want a new vacuum. I started shopping for a Roomba. They’re a lot more expensive but the money saved on constantly buying new vacuums will help. My Eufy doorbell works well so far but it will be hard to recommend any of their products going forward.
