Robot vacuum reports 'Error 8' / voice prompt 'Error 8: Fan error' and stops, suction is weak or absent.

Safety first: Turn off the robot, remove the dustbin, and disconnect from the dock.

• 1. Check and clean the dustbin:
  • Empty the dustbin completely.
  • Clean the dustbin air channels and mesh with a soft brush.
• 2. Inspect the filter:
  • Remove the HEPA/filter from the dustbin.
  • Tap it gently over a trash can to remove dust (or replace if very dirty or wet).
• 3. Check the fan inlet:
  • Look into the cavity where the dustbin sits; this is the fan inlet.
  • Remove any visible debris with tweezers or a vacuum cleaner (do not insert metal tools into the fan).
• 4. Test suction:
  • Reinstall the dustbin and filter.
  • Power on the robot and start a cleaning cycle; listen for the fan spinning.
• 5. If the fan does not spin or makes loud grinding noises:
  • Remove the top cover to access the fan module.
  • Check the fan connector on the mainboard.
  • If the fan is seized or burned, replace the fan motor module.
