How to Fix / Troubleshooting
Safety first: Immediately turn off the robot and remove it from the dock. Do not continue to operate it until the cause is identified.
- Inspect brushes: Remove the main and side brushes. Clear all debris and ensure they rotate freely.
- Check for melted plastic: Look around the brush ends and motor areas for signs of melting or discoloration.
- Smell test: With the robot off, smell near the fan exhaust. If the burning smell is strongest there, the fan motor may be failing.
- Do not reuse until serviced: A persistent burning smell indicates a serious fault. Have the robot inspected and repaired by a qualified technician.
