How to Fix / Troubleshooting

Safety first: Turn off the robot and remove it from the dock. Do not continue using if there is a burning smell.

  • 3. Replace old battery:
    • If the robot is several years old and runtime has decreased, replace the battery pack.
  • 4. Inspect wiring:
    • Look for pinched or damaged wires near the wheels, brushes, and mainboard.
  • 5. If random shutdowns persist:
