摘要： The invention is a bare floor cleaning appliance provided with a foot pedal for raising and lowering the suction nozzle while simultaneously energizing and de-energizing the independent drive motor powering a horizontal axis rotary agitator. The foot pedal is depressed once to lower the suction nozzle to a position closest to the floor surface and the horizontal rotary agitator is energized to clean the floor surface. Suction from the motor-fan assembly is used to pick up dirt and used cleaning solution. The foot pedal is depressed one more time to raise the suction nozzle from the floor surface and de-energize the horizontal rotary agitator. In this mode, suction from the motor-fan assembly is used to pick up dry objects including dirt. The foot pedal operates the switch for energizing and de-energizing the independent electric motor by rotating a mode indicator operably connected to the foot pedal. Depressing the foot pedal once rotates the mode indicator to a first position which toggles the switch from the off position to the on position. When rotated into this position, an first indicating portion on the mode indicator is rotated underneath a first viewing window formed in the hood of the cleaner foot. Depressing the foot pedal another time rotates the mode indicator to a second position which toggles the switch from the on position to the off position. A second indicating portion on the mode indicator rotates underneath a second viewing window formed in the hood of the foot. At the same time the first indicating portion is rotated out of sight of the first viewing window.
摘要翻译： 本发明是一种裸地清洁器具，其具有用于升高和降低吸嘴的脚踏板，同时为由水平轴旋转搅拌器供电的独立驱动马达通电和断电。 脚踏板被按下一次以将吸嘴降低到最接近地板表面的位置，并且水平旋转搅拌器被通电以清洁地板表面。 用电机风扇组件吸取污垢和使用的清洁溶液。 脚踏板再次被压下以从地板表面升起吸嘴，并使水平旋转搅拌器断电。 在这种模式下，电动机 - 风扇组件的吸力用于拾取包括污垢在内的干燥物体。 脚踏板操作开关，通过旋转可操作地连接到脚踏板的模式指示器来使独立电动机通电和断电。 按住脚踏板一次将模式指示器旋转到第一位置，该位置将开关从关闭位置切换到打开位置。 当旋转到该位置时，模式指示器上的第一指示部分在形成在吸尘器脚的罩中的第一观察窗口的下方旋转。 再次按下脚踏板将模式指示器旋转到第二位置，该位置将开关从打开位置切换到关闭位置。 模式指示器上的第二指示部分在形成在脚的罩中的第二观察窗下方旋转。 同时第一指示部分旋转出第一观察窗的视线。

摘要： A novel upright, hot water carpet cleaning extractor is disclosed. The overall configuration and operation of the extractor is similar to that of a typical upright vacuum cleaner and may be similarly operated in both the forward and reverse direction. The herein taught extractor comprises a base frame including the floor suction nozzle, suction fan, cleaning solution distributor, and a removable combination air/liquid separator and recovery tank. A manipulative push-pull handle is pivotly attached to the base frame having a removable cleaning solution supply tank supported thereon. The herein taught upright extractor is easily stored, self contained, easy to operate and requiring minimal effort by the operator.

摘要： A vacuum cleaner conversion arrangement is disclosed which, particularly, may be advantageously applied to a dirt cup cleaner. In this application, the conversion hose confluently communicates with the dirt cup when the cleaner is in converted condition so that suction air flows from the dirt cup to the motor-fan system of the vacuum cleaner in either of its floor or hose modes of operation. The conversion arrangement generally includes a conversion adapter having a closure means for sealing off its conversion hose and stanchions for conveniently mounting the ends of the same hose when it is not in use. The closure means may take the form of an outer door or an internal flapper valve plate.

摘要： A suction cleaner nozzle has a nozzle body enclosing an agitator chamber, which has an elongated suction inlet opening. An agitator is disposed in the agitator chamber such that the agitator extends partially through the suction inlet opening for agitating a surface to be cleaned. A duct is connected to the nozzle body and located adjacent the agitator chamber. The duct extends parallel to the rotative axis of the agitator. A turbine rotor is rotatably connected to the nozzle body and operatively connected to the agitator

摘要： A gravity feed liquid cleaning solution supply system particularly suitable for use on an upright hot water carpet extractor having a free floating brush assembly is disclosed. The unique system generally comprises a stationary fluid supply manifold positioned above a free floating brush assembly having multiple laterally disposed rotary brushes rotatable about vertical axle shafts suspended from a laterally disposed brush support beam. The support beam includes open top troughs, one above each individual brush, into which liquid cleaning solution cascades from the overhead manifold. From each fluid trough, the cleaning solution is conveyed to the center cup of an associated rotary brush through a conduit integrally molded into the brush support beam. By this unique structure liquid cleaning solution is supplied to the free floating brush assembly without restricting the floating movement of the scrubbing brushes over the surface being cleaned.
