If your Roomba robot vacuum side brush is not spinning or not spinning as much as it used to, then we have some things for you to try.
It’s not uncommon for your robot vacuum’s side brushes to stop working or not work as well as they used to. The steps in this post will help figure out why they’re not spinning and what you can do to fix the problem.
Roomba’s Side Brush Not Spinning – Fix
The most common reason why your Roomba’s side brushes are not spinning is most often to do with hair or debris getting stuck.
It’s not uncommon for hair and dust to get trapped on the side brush and slowly cause it to not work.
If the brush is still spinning just fine, but it’s not cleaning as well, it could be the brush is worn out. As the brush is used, it will lose some length, which keeps it from cleaning or reaching as far as it used to. Getting a replacement brush* is the fix, and you should replace them every 6 months or as they lose their cleaning ability.
How To Clean Roomba Side Brush
Cleaning the Roomba side brush is super easy, and we’ll show you how below.
1. Remove One Phillips Head Screw
Remove the one Phillips head screw, so you can lift off the side brush as shown in the picture below.
Once the side brush is off, remove any hair or debris that may be stuck to it or under the cap of the side brush.
If the brush is old, now is a good time to replace it with a new one.
2. Remove Bottom Cover
When you have removed the side brush, the next thing you need to do is remove the bottom cover.
The screw locations are located below.
3. Remove Side Brush Motor Module
When you have the bottom cover off, you can now remove the side brush motor module (the blue box). You will need a smaller Phillips head screwdriver to get this out, it’s only two screws.
4. Clean Side Brush Motor Contacts
When you have the blue side brush motor out, you’ll see the contacts on it and the robot vacuum.
I’ve seen these contacts get dirty or corroded and that is what keeps it from working. Using rubbing alcohol and a clean rag, clean these contacts to remove any dirt or corrosion. Note: Remove the battery before cleaning and let the rubbing alcohol dry before using.
Roomba Side Brush Still Not Working?!
If you cleaned the side brush, and it’s still not working, the best thing to do is replace the blue motor module.
You can take it apart, but you need a special screwdriver and most often when you open it there is nothing left to clean, and it’s just a waste. It’s the motor that has gone bad, and buying a new module with a new motor is what you need to do.

Side Brushes Are Not Needed
Your Roomba robot vacuum will work without the side brush.
Some people even like it this way, as they clean either large areas or the brushes fling too many things around.
Though, side brushes are worth it, especially if you want the robot vacuum to clean corners. The side brush also funnels the dirt into the Roomba, so overall, you want to keep it.
