It has never been so easy, convenient, and quick to get windows and other smooth surfaces sparkling clean. With the vibrating cordless wiper KV 4, dirt on the surface can be removed without the hassle of scrubbing, thanks to electric water dispensing and supporting vibrations. The remaining liquid can then be suctioned off without drips or streaks using the cordless window vacuum WV 2. The KV 4 package includes an additional cleaning cloth, four 20-milliliter bottles of cleaning solution, a charger, and other extras.
