Roomba Brush not Spinning

Why is my Roomba Brush not Spinning?

The Roomba vacuum cleaner is furnished with a sweeping side brush. It is considered an essential tool, as it collects dust and dirt into the robot’s suction channel. So, when the brush stops working effectively, you know you have a problem. Before you learn how to fix Roomba brush not spinning, you need to know why it’s not working in the first place.

In this blog, we’ll discuss the infamous question “Why is my Roomba brush not spinning” along with its troubleshooting tips.

Reasons for the Roomba Brush not Spinning

There are three reasons why the Roomba brush not spinning error may arise. The most common reason for it is the hair and dust build-up underneath the brush, mostly when it’s not frequently cleaned. The reasons are explained thoroughly below:

The brush module is stuck 

One of the most common reasons for the brush not working is that it’s jammed with hair or debris. You are required to clean the brush every once in a while. If you don’t clean it, a lot of dust and dirt will build up under it.

Similarly, grime and filth will collect in the side brush gearbox. The gearbox contains rotating gears within. The motor transfers power to the side brush, which results in its spinning. If the gearbox is filled with dirt and gunk, the gears won’t be able to turn effectively and resulting in the Roomba brush not spinning.

Ungreased Brush Motor

Another justification for the brush not spinning is that the motor is weak. However, this reason isn’t as common but it could happen. But no need to worry! As you can easily replace it!

Impaired parts

The brush could not be spinning because the parts are damaged. To verify this, you can run the Demo on the Roomba and examine if the brush motor is spinning at the right time. If the motor doesn’t turn on, it could be due to the failure of the module.

Although, if you have noticed that the motor is working but the brush doesn’t rotate. Then you need to scan the yellow bit of the brush for any breaks or tears. If there’s any crack on the yellow part of the brush, then this could be the reason preventing it from spinning. If that’s the case, then you need to replace the brush.

These are the reasons for the Roomba brush not spinning.
