发明名称 Cleaning appliance
摘要 An appliance is provided which may be utilized to wipe clean a surface. The appliance contains a handle and a frame such as a yoke or otherwise shaped holding unit for a flexible member such as sponge or cellular plastic member or otherwise shaped flexible unit. A sheet-like material such as or filament-reinforced absorbent paper is fed from a roll supply thereof supported by the support for the appliance, around the flexible portion of the appliance and held against a frame or retaining unit. Thus, as each section of the sheet or paper is soiled or used up, a new section thereof may be easily fed across the face of the flexible unit and retained in place.
