Possible Causes
How to Fix / Troubleshooting
Safety first: Turn off the robot and let it cool for at least 30 minutes in a shaded, ventilated area.
- Check airflow path: Remove and empty the dustbin. Clean all filters thoroughly and ensure they are dry.
- Inspect brushes: Remove the main brush and side brush. Clear all hair and debris from bristles and bearings.
- Check vents: Inspect any exhaust vents on the robot body and clear dust buildup.
- Environmental check: Avoid running the robot in rooms above 35°C (95°F) or in direct sunlight for long periods.
- Test again: After cooling and cleaning, restart the robot. If E12 recurs quickly, the suction or drive motor may be failing and should be inspected by a technician.
Warning: Do not cover the robot with cloths or run it under furniture with very low clearance that blocks vents; this can cause repeated overheating.
