How to Fix / Troubleshooting

Safety first: Stop using the vacuum immediately, turn it off, and remove the battery. Do not ignore burning smells.

  • Inspect the main floor brush and mini motorized brush for hair or fibers tightly wrapped around the roller ends. Remove all obstructions.
  • Check for melted plastic around the brush bearings or motor vents.
  • If the smell comes from the main body, do not attempt further use; the main motor or PCB may be overheating.
  • Replace the affected component (e.g., motorized floor head or main body assembly) and have the unit inspected by a qualified technician before further use.
