摘要： A novel carpet extractor is disclosed having a first cleaning liquid conduit that communicates a supply reservoir with a cleaning liquid distributor via a first valve and a second cleaning liquid conduit that communicates the supply reservoir with the liquid distributor via a second valve. The first valve is actuated by a main trigger and the second valve is actuated by a surge button, both of which are conveniently located in the hand grip on the handle of the machine for propelling the machine over a floor surface. A first normal flow of cleaning liquid is obtained for normal cleaning by depressing the trigger and a second greater flow of cleaning liquid is obtained by depressing the button and the trigger simultaneously. A mechanism is preferably included that will open the first valve in the event an operator depresses only the surge button.

摘要： An air/liquid separator is provided in a hollow, preferably transparent, removable lid on a recovery tank of a wet pickup suction cleaner. The lid has a wall therein dividing the lid into an inlet/separating chamber and an exit chamber. Liquid and dirt entrained working air enters the inlet chamber and flows horizontally across the inlet chamber over a plurality of discharge openings passing through the lid bottom plate, such that the stream of dirty liquid and air is redirected downward through the discharge openings into the recovery tank. The plurality of discharge openings in the lid bottom plate are arranged generally progressively along the stream of liquid and air entering and flowing across the inlet chamber. The discharge openings preferably increase in size moving downstream in the inlet chamber, i.e. away from the entry into the inlet chamber. The exit chamber fluidly communicates with the interior of the recovery tank through an exit opening passing through the lid bottom plate. A vacuum is preferably drawn upon the exit chamber by an electric fan for providing the required working air flow through the combined air/liquid separator.

摘要： A vacuum cleaner includes a dirt separation system that has a dirt cup retaining a filter assembly having a screen element, an exit, and a filter element disposed between the screen element and the exit. A nozzle disposed in the dirt cup directs an airstream generally parallel to the surface of the screen element so that particles in the airstream are primarily separated by the screen element and, as the airstream ultimately travels towards the exit in the dirt cup, are secondarily separated by the filter element.
