Possible Causes

Failed suction fan motor, Blocked air path causing overcurrent, Loose fan motor connector, Main PCB fan driver failure

How to Fix / Troubleshooting

Safety first: Turn off the robot and remove it from the dock. Do not run the unit with a burning smell or loud grinding noise.

  • Check for blockages: Remove the dustbin and filter. Inspect the air inlet, cyclone, and exhaust path for clogs (dust clumps, paper, pet hair). Clear any obstructions.
  • Clean or replace filter: If the pre‑filter or HEPA filter is heavily clogged, clean according to the manual or replace with a genuine Samsung filter.
  • Test suction: Reinstall the bin and filters, then start the robot. Listen for the fan motor. If it does not spin or makes harsh noises, stop immediately.
  • Service if needed: A failed fan motor or driver circuit requires internal disassembly and replacement of the suction motor module or main PCB by a technician.
