How to Fix / Troubleshooting
Safety first: Immediately turn the robot OFF and remove it from the dock. If you see smoke or the smell is strong, unplug the dock and move the robot to a non‑flammable surface.
- 1. Allow to cool: Wait at least 30 minutes before further inspection.
- 2. Clean brushes and filters: Remove hair from the main and side brushes, and clean/replace filters.
- 3. Inspect for melted plastic: Check around the brush ends and motor vents for signs of melting or discoloration.
- 4. Test briefly: Run the robot for a short period while monitoring for smell. If the odor returns quickly, stop use.
- 5. Seek service: A burning smell often indicates motor or wiring damage. Have the robot inspected by an authorized Bosch technician before further use.
