  • Patent number: 8458852
    Abstract: The present invention relates to a system of creating and applying a heated cleaning fluid to a surface. The system includes a housing with a first, a second and a third exhaust gas opening. A first, second, and third heat exchanger are enclosed within the housing. The first and second exchangers are serially arranged, while the third is at an angle relative to the first and second and directly adjacent to the first opening. Super heated exhaust gas flows through first opening and third exchanger. Heated gas flows through the second opening and passes below the third exchanger. Super heated exhaust gas exiting the third exchanger mixes with the heated gas in a mixing chamber of the housing, which is then supplied to the first and second exchangers. Fluid passes through the three exchangers and exits the third exchanger heated. That heated fluid passes to a cleaning wand for application.

  • Publication number: 20120115401
    Abstract: A floor care apparatus is provided that utilizes at least one cylindrical pad to remove a floor finish. More specifically, a cylindrical pad having an abrasive surface is integrated onto a cylindrical scrubber brush or associated core or roller commonly used in the art. The main outwardly-facing surface of the pad contacts the floor to remove a predetermined amount of floor finish wherein generated debris is expelled away from the pad. After finish removal, a new layer of finish is applied to the floor. Thus, the need to remove all finish layers from a flooring surface is alleviated, which saves time and money.

  • Publication number: 20120096671
    Abstract: A floor cleaning device employing a brush assembly is provided. The brush assembly includes a front brush and a rear brush that spin about an axis line generally parallel to the surface being cleaned. The spinning rotation of the brush along with the configuration of the housing help provide an airflow path that sucks debris from the surface being cleaned. The debris is directed to a hopper wherein larger items are captured and smaller items are suctioned into a vacuum bag.

  • Publication number: 20110315787
    Abstract: A pressure washer device is provided that employs an unloader bypass valve that directs a selective amount of fluid via a small diameter bypass line back to a water storage tank. The small amount of fluid allows for the pump to remain working and introduces cooler water into a bypass circuit, thereby allowing the thermal relief valve to be omitted. The diameter of the bypass line is of such a diameter to prevent siphonage of the detergent associated with the pressure washer system into the water storage tank as well.
