DEVICE HAVING DUAL RENEWABLE BLADES FOR TREATING A TARGET SURFACE AND REPLACEABLE CARTRIDGE THEREFOR
Abstract:
A device (20) for treating a target surface, such as occurs when cleaning a window. The device has a squeegee blade or other member to apply pressure to the target surface. A sheet (22) movably covers the blade, to present a fresh covering to the target surface with each use. The fresh surface provides for improved removal of the liquid from, or improved treatment of the liquid on, the target surface. Additionally a sheet may comprise a prewetted substrate (34) to apply the liquid to the target surface. One or both of the sheets may be disposed in a cartridge insertable to and removable from the device.
