How to Fix / Troubleshooting
Safety first: Immediately turn OFF the robot and remove it from the dock. Do not continue to run it until the cause is found.
Step-by-step:
- Inspect for jams: Check main brush, side brush, and wheels for hair or debris jams. Clear thoroughly.
- Check for melted plastic: Look around motors and brush housing for signs of melted plastic or discoloration.
- Smell components: Carefully smell near the suction outlet and wheel motors (when cool) to localize the odor source.
- Clean filters and vents: Ensure airflow is not blocked by clogged filters or dust buildup.
If the burning smell returns quickly or you see smoke or charring: Stop using the robot and seek professional repair. The affected motor or control board must be replaced.
