Safety first: Remove the battery before opening the filter compartment.

1. Check exhaust filter: Ensure the HEPA or fine dust filter is present, correctly oriented, and fully seated.
2. Inspect filter frame and seals: Look for cracks or gaps in the filter frame and surrounding plastic. Replace if damaged.
3. Use genuine filters: Install only Miele-approved filters designed for your cordless model.
4. Clean surrounding area: Wipe away any dust that has accumulated around the exhaust to monitor for new leakage.
