Abstract: A floor cleaning device includes a base. A cleaning fluid supply tank is carried by the base. A source of pressure communicates with the cleaning fluid supply tank which pressurizes a cleaning fluid held in the cleaning fluid supply tank to an above atmospheric pressure. A fluid delivery system delivers pressurized cleaning fluid from the cleaning fluid supply tank to a surface to be cleaned.

Abstract: An upright vacuum cleaner (A) includes a housing (B) having a suction airstream inlet and a suction airstream outlet. A dirt container (50, 500) is selectively mounted to the housing for receiving and retaining dirt and dust separated from the suction airstream. The suction airstream inlet and the suction airstream outlet are in fluid communication with, respectively, an inlet and an outlet of the dirt container. The dirt container includes a first cyclonic air-flow chamber (66, 508) and a second cyclonic airflow chamber (68, 510), each cyclonic airflow chamber including a longitudinal axis. The second cyclonic airflow chamber is spaced from the first chamber, wherein the first and second chambers are each approximately vertically oriented and are arranged in a parallel relationship. An air manifold (52, 540, 540?) is disposed at a top portion of the dirt container. The air manifold includes an inlet section (54, 536, 565) through which dirty air passes and an outlet section (138, 560, 560?).
