How to Fix / Troubleshooting

Safety first: Turn OFF the robot and remove it from the dock before opening any covers.

  • Check for movement-triggered shutdown: Gently tap or move the robot while it is running to see if it shuts off, indicating a loose connection.
  • Inspect battery compartment: If user-accessible, open the battery door and ensure the battery pack is firmly seated and its connector is fully inserted.
  • Toggle main switch: Operate the main power switch several times to clear minor oxidation on contacts.
  • Test again: Run a full cleaning cycle and monitor whether the robot still stops unexpectedly.
  • Service if unresolved: If the problem persists, there may be an internal wiring or PCB fault that requires professional diagnosis and repair.
