Possible Causes
How to Fix / Troubleshooting
Safety first: Immediately turn OFF the robot, remove it from the dock, and disconnect the battery if accessible. Do not continue using the robot until the cause is identified.
- 1. Inspect brushes: Remove the main and side brushes and check for jams or melted plastic. Clean thoroughly.
- 2. Check for visible damage: Look for melted plastic, discoloration, or burn marks around the brush motor, fan intake, and connectors.
- 3. Smell test: Carefully smell near the fan outlet and brush motor area (with the robot OFF) to localize the source.
- 4. Do not reuse until repaired: If any component shows signs of overheating, replace the affected motor or wiring harness before using the robot again.
Warning: Burning smells indicate a fire risk. If you cannot quickly identify and correct a simple jam, contact a professional technician or Trifo support.
