How to Fix / Troubleshooting

Safety: Stop using the vacuum immediately, turn it off, and remove the battery. Do not continue operation until the cause is found.

  • Inspect floor head: Remove the brushroll and clear all hair and debris. Check for melted plastic or discoloration.
  • Clean filters and airflow path: Ensure all filters are clean and the wand is not blocked.
  • Smell source: Determine whether the odor comes from the main body or the floor head.

If the smell persists after cleaning, or if you see smoke or melted parts, the motor or wiring is likely damaged and must be replaced by a professional.
