How to Fix / Troubleshooting
Safety: Turn OFF the robot and remove from dock.
- Check battery seating: If accessible, open the battery compartment and ensure the battery connector is firmly plugged in.

- Monitor pattern: Note if restarts occur on heavy carpet or when brushes encounter resistance; if so, reduce load by cleaning brushes.
If random reboots continue on clean floors, the main control board or battery pack may need replacement.
