Possible Causes

Blocked airflow causing motor overheating, Brush bar jam causing motor strain, Failing motor windings, Foreign object melting inside floorhead

How to Fix / Troubleshooting

Safety first: Immediately switch OFF, remove the battery, and allow the unit to cool. Do not continue using a vacuum that smells of burning.

  • 1. Check for blockages: Inspect and clear the bin, filters, wand, and floorhead.
  • 2. Inspect the brush bar: Remove the brush bar and clear any jams. Check for melted plastic or scorch marks.
  • 3. Smell the motor vents: After cooling, gently smell near the motor vents. A strong electrical burning smell suggests motor damage.

If the burning smell returns quickly after clearing blockages, stop using the vacuum and have the motor or floorhead inspected and replaced as necessary.
