How to Fix / Troubleshooting

Safety first: Turn off the robot and remove the dustbin and main brush before inspecting.

Step-by-step:

  • Check for blockages: Look into the suction inlet behind the main brush and into the dustbin air outlet. Remove any visible debris.
  • Clean dustbin thoroughly: Empty the bin and wipe internal channels with a dry cloth. Ensure the filter is clean and properly installed.
  • Power cycle: With the bin reinstalled, power the robot on and start a cleaning cycle. Listen for the fan spinning up.

If the fan does not run or the error returns: The suction fan assembly is likely faulty and must be replaced. This requires opening the robot and disconnecting the fan from the main board; consider professional service.
