Vacuum emits a burning smell or hot plastic odor during or after use.

Safety first: Immediately turn OFF the vacuum, remove the battery, and allow it to cool. Do not continue using it until the cause is found.

Steps to try:

• Inspect brushroll and belt: Remove the nozzle bottom plate. Check for melted belt rubber or scorched plastic around the brushroll. Replace the belt and clear any jams.
• Clean filters and airflow path: Ensure all filters are clean and the air path is unobstructed to reduce motor load.
• Check for discoloration: Open the main body (if comfortable) and inspect the motor and PCB for burnt spots or melted insulation.
• Do not ignore persistent smell: If the burning odor returns quickly after cleaning, discontinue use and replace the motor assembly or seek professional service.
