I have a Samsung Powerbot R7040 VR1AM7040WG/AA. Recently the machine started making an awful grinding noise when trying to vacuum. I normally keep the brush pretty clean, but I decided to replace the roll brush. Still making the sound.
I took the unit apart and cleaned out all the dog hair on the inside. I also took apart the brush motor and cleaned it out, it was very full.
When I run the unit with a roller brush, it makes an awful noise, I am not so certain the brush is even spinning. When I take the brush out, the noise is mostly gone. I did notice a flat spot on the brush belt - probably 2-3 teeth are no longer there.
Is it safe to assume that I burned out the brush motor?
Can anyone provide me a p/n for the brush motor?
I found a 7010 brush motor on ebay for sale, and it looks to be the same as what I have. Are the 7010 and 7040 motors the same?
