How to Fix / Troubleshooting
Safety first: Turn OFF the main power switch before opening any covers.
- Check ventilation: Ensure vents are not blocked and filters are clean to prevent overheating.
- Inspect battery connection: Remove the battery cover and verify the battery plug is firmly seated in the robot's socket.
- Full recharge: Charge the robot fully and then run a test cleaning to see if the shutdown timing is consistent.
- If shutdowns continue: Replace the battery pack. If the issue persists even with a new battery, the main control board or power switch may be defective and require professional service.
