How to Fix / Troubleshooting
Safety first: Turn OFF the robot and flip it over.
- 1. Remove and inspect main brush: Check the drive end of the brush for rounded or worn plastic. Replace the brush if the coupling is damaged.
- 2. Inspect drive socket: Look inside the robot's brush drive socket for stripped plastic or missing teeth.
- 3. Reseat brush: Reinstall the brush, ensuring the drive end is fully inserted into the socket and the cover is latched securely.
- 4. Test operation: Run the robot and observe whether the brush now spins.
- 5. If the brush still does not spin: The main brush motor module or its clutch/gearbox may be slipping and require replacement.
