The Edge-Sweeping Brush can stop spinning if it's jammed with hair or debris, or if it wasn't reinstalled correctly after a cleaning. Let's get it spinning again.
- Flip the robot over. You'll see the yellow Edge-Sweeping Brush on the side.
- Use a small screwdriver to loosen the screw holding the brush in place. Don't remove it completely; just loosen it enough to free the brush.
- Pull the brush straight out of its housing. Remove any hair or string wrapped tightly around the ends or the central axle.
- Clear out any debris from the empty brush socket inside the robot.
- Reinsert the brush, making sure it seats fully into the gear mechanism, and then tighten the screw back down. Don't overtighten.
If that didn't work: The brush itself might be worn out or broken. The Edge-Sweeping Brush has a recommended replacement frequency of every 12 months (or every 6 months if you have a pet). Contact iRobot Customer Care for a genuine replacement part.
Heads up: This brush, along with the Multi-Surface Brushes, should be cleaned once a month (twice a month with a pet) to prevent this kind of jam from happening in the first place.
