Why is the suction performance inadequate on my Kärcher DS 5500?
- AAlexandra SummersJul 28, 2025
If the suction performance of your Kärcher Vacuum Cleaner is inadequate, several factors could be responsible. Ensure the intermediate filter is correctly inserted and not dirty; clean or replace it if necessary. A dirty HEPA-Plus filter may also be the cause, so replace it if needed. Check for blockages in the accessory or deposits in the suction manifold and remove them. Verify the water container is correctly inserted and the false air slide on the handle is closed.
