Roomba side brush not spinning after replacement 

Roomba’s side brush is the small circular brush at the left and right of the machine used to sweep dust and debris into the machine’s path so it can be picked up by the main brush. If this brush stops turning, check to make sure it is not clogged with debris. If there is no debris in its path, remove the side brush and test to see if it will spin freely when your Roomba is powered on.

If you replace the side brush and it still doesn’t spin, then you need to check the motor. The motor may be bad or the gear teeth may be stripped. If the gear teeth are stripped, it’s cheaper to just buy a new motor than try to fix it.

First, get an ohmmeter and measure the resistance between the three terminals of the motor. If there is not a short between any of them, then the motor is probably good.

If there is a short between two of them, then you have a bad motor.

The other possibility is that something is jammed in the side brush mechanism and preventing it from turning. Turn off your Roomba and remove the bin and battery. Then remove all four screws holding down the cover on top and lift off the cover. You can then check if anything is jammed in there.


So, I have listed the best possible reasons for the Shark Robot vacuum side brush not spinning along with the solutions. If you are still stuck in the situation then you should contact an expert and get your robot vacuum inspected.
