Possible Causes

Motor overheating due to blocked airflow, Failing motor windings, Overloaded brushroll motor, Melted wiring insulation near high-current components

How to Fix / Troubleshooting

Safety first: Immediately switch OFF the vacuum, remove the battery, and allow the unit to cool down. Do not continue using it until the cause is identified.

  • 1. Check for blockages: Ensure all filters, the dust bin, wand, and nozzle are clear to prevent motor overload.
  • 2. Inspect brush head: Remove the motorized head and check for a jammed brushroll or melted plastic near the brush motor.
  • 3. Visual inspection inside: Open the main body and look for discolored, melted, or burnt wiring and connectors around the motor and PCB.
  • 4. Smell localization: Carefully smell near the motor, PCB, and brush head (with the battery removed). Identify which component is producing the odor.
  • 5. Replace damaged parts: Any component showing signs of burning (motor, brush head, wiring harness, PCB) should be replaced. Do not attempt to repair burnt insulation or windings.
