The battery-driven Kobold VG100 window cleaner by Vorwerk combines the standard steps of cleaning a window into one: a microfibre tissue equally wet the pane with water and detergents. At the same time, it removes dirt. With a leveling blade and a strong sucker, the dirty water is directly sucked from the pane. Besides its functionality, the Kobold VG100 convinces with its timeless design and its low weight (995 gram). The washable casing and the removable leveling blade underline its ease of use.
