Dust escapes from the vacuum exhaust, causing visible dust clouds.

Safety first: Remove the battery pack before handling filters.

• 1. Check HEPA filter presence: Open the exhaust filter cover and ensure the HEPA filter is installed.
• 2. Inspect filter: Look for tears, holes, or deformation in the filter media and frame. Replace if damaged.
• 3. Check seating: Ensure the filter is fully seated and the cover is properly latched so air cannot bypass the filter.
• 4. Replace with genuine part: Use only a genuine Grundig HEPA filter designed for your model to maintain proper sealing and filtration.
