Why is the suction performance too low on my Kärcher BD 70 W Classic Bp?

If the suction performance of your Kärcher Scrubber is too low, try these steps: First, shut down the device and drain the waste water. Clean the seals between the waste water tank and the cover, and replace them if they're leaking. Ensure the suction hose is correctly connected to the waste water tank. Check the fluff filter for dirt and clean it if needed. Clean or replace the suction lips at the suction bar. Make sure the cap on the waste water drain hose is closed. Check the suction bar's adjustment. Inspect the suction hose for blockages and leaks, cleaning or replacing it as necessary, ensuring the white marking aligns with the retaining clip when re-inserting the hose.
