The water and cleaning solution is suctioned away from the window - without leaving dirty drops or streaks behind. For streak free results, watch our product video. Thanks to its convenient rechargeable battery operation and compact design, the WV1 guarantees maximum flexibility in cleaning all smooth household surfaces, not just windows. No more wasted paper towels, streaks, drips and all the hassles of traditional window cleaning. With the window vacuum, you'll clean like a pro and 3 times quicker.
