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

Safety first: Stop using the vacuum immediately, remove the battery, and allow the unit to cool. Do not continue to run a vacuum that smells of burning.

Steps to try:

• Inspect brush bar: Remove the brush bar and check for jams. A melted or scorched belt smell indicates drive issues.
• Clean filters and airflow: Ensure all filters are clean and the airflow path is clear to reduce motor load.
• Check for visible damage: Look for melted plastic around the floor head or motor vents.
• Do not ignore persistent smell: If the burning smell returns quickly after cleaning, the motor or wiring may be damaged. Discontinue use and replace the main body or floor head as appropriate.
