Brush Roll Not Spinning
iRobot Roomba Robot Vacuum
Severity: ModerateWhat Does This Error Mean?
A Roomba brush roll that does not spin is almost always jammed with hair, string, or carpet fibre wrapped around the brush end caps. Remove the brush roll and clean both end caps — this fixes the issue in the vast majority of cases.
Affected Models
- iRobot Roomba 600 series
- iRobot Roomba 700 series
- iRobot Roomba e5
- iRobot Roomba i3
- iRobot Roomba i7
- All brush-roll Roomba models
Common Causes
- Hair, string, or carpet fibre tightly wound around the brush end caps
- Debris jammed between the brush roll and the housing
- Brush roll motor fault
- Brush roll not correctly reinserted after cleaning
- Brush end cap bearings worn out on older units
How to Fix It
-
Remove the brush roll by pressing the release tabs on the brush frame.
On most Roomba models, two yellow tabs release the brush frame. Lift out both the brush roll and the flexible beater brush.
-
Cut and remove all hair and fibres from both yellow end caps using scissors.
Hair wraps tightly around the yellow bearings at each end of the brush roll and locks it in place. Cut along the brush in both directions and pull the hair out. This is the most common fix.
-
Clean the brush housing channel and the contact points with a dry cloth.
Debris in the channel where the brush roll sits can prevent it from spinning freely. Wipe all contact surfaces clean.
-
Reinsert the brush roll so the square peg aligns with the square socket.
The brush roll has a square end that must align with the square drive socket. If inserted incorrectly, it will not spin even though it looks seated.
Frequently Asked Questions
How often should I clean the Roomba brush roll?
Clean the brush roll every 1-2 weeks for normal use, or after every run if you have pets or long-haired occupants. Roomba will display an error or reduce suction before the brush roll fully seizes — do not wait for an error before cleaning.
Can I replace the Roomba brush roll myself?
Yes — Roomba brush rolls are user-replaceable and available from iRobot and third-party suppliers. They typically need replacement every 6-12 months depending on use. The replacement process takes under 5 minutes with no tools required.
