Possible Causes
Vacuum motor failure, Loose vacuum motor connector, Firmware glitch disabling suction, Burned-out motor driver
How to Fix / Troubleshooting
Safety first: Turn off the robot before inspection.
Steps to resolve:
- Listen for suction: Start a cleaning cycle and listen closely; if you only hear wheels and brushes but no airflow, the vacuum motor is not running.
- Soft reset: Perform a soft reset and test again.
- Check for clogs: Remove the bin and inspect the suction path for blockages that might have stressed the motor.
When to replace parts: If the vacuum motor never runs, the motor assembly or its driver circuit on the main board is likely failed and must be replaced.
