There are three possible reasons for why the side brush is not spinning on your Roomba.

Reasons why Roomba brush is not spinning

1. The Side Brush Module is Jammed.

The first reason could be because the brush module of your robot vacuum is jammed. The brush can get tangled up in things like thread, string, and other long thin materials. These materials are bad for your Roomba’s extractors to pull into or through its extractors because it can break them or decrease suction power.

If this is the case, you will need to reset your Roomba device. With the battery disconnected, reset it by pressing and holding the CLEAN button for three seconds.

2. The Side Brush Module is Not Installed.

The second reason could be because the side brush module is not installed properly or is missing entirely. To check if it is installed properly, there should be one screw holding down the cover that has the brush attached to it. If the brush module is not installed at all or fully, please refer to our guide on how to install the brush here .

3. The Side Brush Motor Is Not Working.

The third reason could be because of a broken side brush motor. If the Roomba brush is spinning slowly or not at all, there is a chance that something has broken inside of it. If this is the case, you will need to replace the side brush motor.

4. Side brush gearbox issues

Issues with the gearbox can make the brush not spinning properly.

The motor shaft will become jammed and the entire Roomba side brush motor will cease to work.
