Chosen Solution
UPDATE: thank you for all your responses we determine that it was the side brush motor. Ordered a new side brush motor and No More Squealing! YAY Again, thank you all for your help My 4 year old 880 has starting squealing/screaming while running. I’ve cleaned everything but still scrams. I’m afraid it’s the motor, any suggestions
It’s probably the motor, if you’re an expert, you should take it apart - but for most of the time you should ask the previous owner, or company if they can fix it. Again, what I always say “look it up!”. Looking it up might not work…
I had a squealing noise in my Roomba too. which I could trace down to the gearing of the extractor brushes. The motor was slightly displaced so that the gears didn’t connect properly. I was able to fix this temporarily by adjusting the motor with a piece of plastic. but the gears were worn down already so that I had to replace the extractor housing (including motor and gearing). was not a lot of trouble and is totally doable! I found the housing in the Roomba shop, but it was a hidden link I only found using google… I am not shure what the situation is where you come from but here in Germany this was also the cheapest offer!
