Windows, mirror surfaces, glass tables, tiles, and all other smooth surfaces can be effortlessly cleaned with the vibrating cordless wiper KV 4, which includes 2 cleaning cloths, 4 times 20 milliliters of cleaning solution, a charger, and additional extras. Thanks to the electric water discharge combined with vibration, dirt loosens from the surface almost by itself—without the hassle of scrubbing. Two simple controls make the handy cordless wiper intuitive to use. The preparation time is minimal: just fill the tank with the included cleaning concentrate and water, and you're ready to go. The included cleaning cloth for the KV 4 is also washable and thus reusable. After use, any remaining liquid can best be suctioned away with a cordless window vacuum.
