Dust or fine powder escapes from the exhaust, leaving a haze or smell in the room.

Safety first: Remove the battery before accessing filters.

• Check dust bin level: Empty the bin if it is more than 2/3 full. Overfilling can force dust past seals.
• Inspect HEPA/post‑motor filter: Remove the filter and check for tears, holes, or deformation. Replace if damaged or heavily soiled.
• Seat filter correctly: Ensure the filter is installed in the correct orientation and fully locked into its housing.
• Inspect housing for cracks: Look for damage around the filter frame that could allow air to bypass.

Persistent dust emission with a new, correctly fitted filter suggests a cracked housing or internal seal failure, which may require replacement of the filter housing or main body shell.
