Possible Causes

Shorted motor windings, Overheated motor driver components, Hair jam in brushroll causing belt slip, Melted wiring insulation

How to Fix / Troubleshooting

Safety first: Immediately switch off the vacuum and remove the battery pack. Do not attempt to restart the unit until it has been inspected.

Steps after overheating event:

  • 1. Inspect brushroll and belt: Remove the floor head cover and check for hair jams or a melted belt. Replace the belt or head if damaged.
  • 2. Smell test: Carefully smell near the motor vents (with battery removed). A strong burnt electrical odor suggests motor or PCB damage.
  • 3. Visual inspection: If comfortable and out of warranty, open the housing and look for burnt components or melted plastic around the motor and PCB.

Do not continue using a vacuum that has produced smoke or a strong burning smell. The motor or control board must be replaced by a qualified technician, and wiring should be checked for safety.
