Why is my Kärcher KM 75/40 W Bp showing poor cleaning performance at edges?

For poor cleaning performance at edges with your Kärcher Floor Machine, try adjusting the side-brush lowering. You may also need to replace the side brush or lower the side brushes. Check the drive belt of the side brush. If the issue persists, contact Kärcher Customer Service.
