How to Fix It
- Flip the robot over and unlock the brush guard.
- Lift the main brush out of its cradle.
- Use the included tool or scissors to cut and pull away all hair from the brush and end caps.
- Remove the colored end cap (twist or pull) and clean debris from the bearing.
- Spin the brush in your hands — it should turn freely with light resistance.
- Wipe out the brush compartment and reinstall the brush, ensuring it locks in place.
- Restart the robot. If the brush still won't spin under power, replace the brush or have the motor serviced.
