With the new vibrating battery wiper KV 4 from Kärcher, smooth surfaces such as windows, mirrors, glass tables, tiles, and many more can be cleaned effortlessly. The battery wiper makes cleaning easier through electric water discharge and vibrations generated by the battery-operated motor. Dirt loosens almost on its own when passing over soiled surfaces – tedious scrubbing is a thing of the past. With just two controls, the new cleaning device is intuitive to use. Additionally, it is handy and requires a short preparation time. Once the tank is filled with the included cleaning concentrate and water, the cleaning process can begin. The included cloth for the KV 4 is also washable and thus reusable. After use, any remaining liquid can be best suctioned away with a Kärcher battery window vacuum.
