Possible Causes

How to Fix / Troubleshooting

Safety first: Immediately turn OFF the vacuum, remove the battery pack, and move the unit to a non-flammable surface. Do not continue using it until the cause is identified.

  • Step 1 – Smell location: Carefully smell near the floorhead, wand, and main body (once cooled) to localize the source.
  • Step 2 – Inspect floorhead: Open the floorhead and check for a melted or deformed belt, or plastic rubbing points. Replace the belt or floorhead if damaged.
  • Step 3 – Check for blockages: Ensure all vents and airways are clear to prevent overheating.
  • Step 4 – Motor/PCB evaluation: If the smell comes from the main body and is electrical (sharp, acrid), the motor or PCB may be failing. Do not reuse the vacuum until these parts are inspected and replaced as needed.

Warning: A persistent burning smell is a serious hazard. Discontinue use and seek professional service.
