Safety first: Immediately switch OFF the vacuum and remove the battery. Do not continue to operate the unit.

Inspect filters and airflow: Check and clean all filters and air paths. However, if smoke or strong burning smell was present, assume internal damage.
Check for melted plastic: Look for discoloration or deformation around the motor vents.
Do not attempt to run again: Running a smoking motor can cause fire or further damage.
