Cordless vacuum’s post-motor exhaust is dusty; fine dust is seen blowing out of the rear vents.

Safety first: Remove the battery before accessing the exhaust filter.

• Remove HEPA filter: Open the exhaust filter cover and remove the HEPA/post-motor filter.
• Inspect filter: Look for tears, holes, or deformation. If damaged, replace immediately.
• Check seating and housing: Ensure the filter sits flat and the cover closes fully. Inspect the housing for cracks that could bypass the filter.
• Replace filter: Install a new Bush-compatible HEPA filter if there is any doubt about the old one’s integrity.
