摘要： A cleaning device utilizing the properties of a fluid at atmosphere plus pressure or above atmospheric pressure to effect a cleaning operation. An electric motor on the cleaning device generates a small stream of atmosphere plus fluid such as, but not necessarily limited to, air, which stream of fluid is made to ''''bend'''' within the cleaning device, and reverse the direction of flow of the fluid stream. This design feature accomplishes three objectives: (1) it eliminates the need for the conventional and relatively inefficient vacuum type cleaner; (2) it forces a relatively small volume of fluid to attach itself to the underside of a horizontal surface; and (3) it encourages the relatively small volume fluid stream to entrain within its path substantially large volumes of dust-saturated fluid. Thus, instead of ''''sucking up'''' dirt as conventional cleaning devices of this nature do by means of vacuum or negative pressure, the cleaning device in this invention uses a stream of positive pressure fluid to push the dirt-and-dust-saturated fluid into a suitable receptacle.
