Abstract
Abstract The handle of a window cleaning device has a opening through which a squeeze bottle for water protrudes. A vaporizing chamber is partially embedded in a heat conductive core associated with one or more heating elements and forms at one end a dispensing nozzle continuously open to ambient atmosphere. The squeeze bottle is adapted to dispense cleaning fluid such as water into the vaporizing chamber wherein it is vaporized and subsequently discharged as a high velocity vapor through the nozzle. A wiper blade is attached to the device adjacent the discharge nozzle to strike off the condensed vapor formed on a window or like surface for cleaning purposes.
