How to Fix / Troubleshooting

Safety first: Stop using the vacuum immediately, remove the battery, and allow the unit to cool. Do not ignore burning smells.

Steps:

  • Check brush bar and belt: Remove the floorhead and inspect the brush bar and belt for melting, discoloration, or jammed debris. Replace damaged parts.
  • Clean filters and airflow: Ensure all filters and air paths are clear to prevent motor overheating.
  • Inspect for scorch marks: Look around the motor vents and floorhead for signs of melting or burn marks.

If the smell persists after cleaning and replacing obvious damaged parts, the main motor or wiring is likely compromised. Do not continue using; seek professional repair or replacement.
