How to Fix / Troubleshooting
Safety first: Turn OFF the robot and unplug the dock. If you smell burning plastic or see smoke, stop using the robot immediately.
- 1. Deep clean dust path: Empty the dust bin, clean or replace the filter, and wipe the bin with a slightly damp cloth. Let it dry completely.
- 2. Clean brushes: Remove and clean the main and side brushes, removing all hair and debris.
- 3. Check mop pad: On mop models, remove the mop pad and wash it. Do not store the robot with a wet pad attached.
- 4. Inspect for overheating: Run the robot briefly and then feel near the fan and motors. If any area becomes excessively hot or the burnt smell persists, stop use.
- 5. Replace components: Replace a discolored or burnt‑smelling vacuum fan motor assembly or main brush motor. If unsure, consult a technician.
