Unpleasant musty or burning smell from the vacuum exhaust.

Safety first: Remove the battery and allow the vacuum to cool before inspection.

• 1. Clean or replace filters: Remove pre-motor and HEPA filters. Wash if allowed, or replace if heavily soiled or smelly.
• 2. Clean dust bin and cyclone: Empty the bin and wipe with a slightly damp cloth. Allow to dry completely before reassembly.
• 3. Inspect brush bar: Remove hair and fibers that may be rubbing and heating on the brush bar or end caps.
• 4. Check for burning signs: If you see scorch marks or melted plastic near the motor vents, stop using the vacuum and seek service.
