Unpleasant or burnt smell coming from exhaust air

Safety: Remove the battery. If you smell burning plastic or electrical odor, stop using the vacuum immediately.

• Clean/replace filters: Wash or replace pre-motor and HEPA filters. Odors often accumulate in these components.
• Inspect brushroll and nozzle: Remove any melted plastic, string, or hair that may be rubbing and burning.
• Check for overheating: If the smell is sharp and electrical, the motor may be overheating. Do not continue to run the unit.
• Service if burning persists: A persistent burning smell indicates motor or wiring damage. Have the motor assembly inspected and replaced if necessary.
