Possible Causes

Slipping or jammed brush belt, Overloaded motor due to blockage, Shorted wiring, Failing motor windings

How to Fix / Troubleshooting

Critical safety: Turn off and unplug the cleaner immediately if you smell burning or see smoke.

  • Inspect brush area: Check for jammed brushes or a melted belt. Replace the belt and clear obstructions.
  • Check for blockages: Ensure the hose, nozzle, and filters are not blocked, causing motor overload.
  • Look for burnt wiring: With the housing open (unplugged), inspect for discolored or melted wires and connectors. Do not operate the unit until damaged wiring is repaired.

If the smell comes from the motor itself or smoke was present, the motor is likely damaged and should be replaced by a professional.
