  • Patent number: 11653801
    Abstract: A vehicle floor mat vacuum machine includes an elongate open mouth communicating with an interior chamber for passage of a floor mat therethrough and between an upper feed roller and a lower brush roller for contacting a carpet surface of the floor mat. A vacuum source connects to a vacuum manifold to create suction, as the brush roller and suction force work in conjunction to remove sand, dirt and other debris from the floor mat. An electric motor, drive belt and reduction gear assembly rotate the feed roller and brush roller in opposite directions with the brush roller rotating at a significantly higher speed. In one embodiment, the vacuum source is a central vacuum system, wherein a solenoid-controlled valve in the vacuum line extending from the feed roller is opened for a timed sequence during operation of the machine.

  • Patent number: 7653965
    Abstract: A system and method for carpet cleaning for cleaning carpets along longer runs from a central tank and vacuum assembly while using less chemicals. The system and method for carpet cleaning includes a central tank and vacuum assembly, a wand assembly, and a hose assembly. The central tank and vacuum assembly facilitates the routing of clean and waste water and creates vacuum pressure for recapturing water applied to a carpet being cleaned. The wand assembly is designed for applying clean water to a carpet to be cleaned, and for recapturing the water in the form of waste water from the carpet. The hose assembly includes a first end operationally coupled to the central tank and vacuum assembly, and a second end operationally coupled to the wand assembly. The hose assembly is used to conduct water and waste water between the wand assembly and the central tank and vacuum assembly.

  • Patent number: 7597767
    Abstract: A paint gun cleaning apparatus is provided that prevents the collection of overspray on the discharge end of the paint gun. The cleaning apparatus includes a drum that defines an aperture for insertion of at least the discharge end of a paint gun. The apparatus also includes a fin assembly inside of the drum for directing paint and solvent discharged from the paint gun away from the paint gun. A splash cone also helps direct discharge away from the center of the drum, laterally toward the fin assembly. The apparatus also includes a source of suction for drawing material discharged from the paint gun away from the discharge end of the paint gun. By preventing the collection of overspray it is not necessary for an operator to wipe the gun clean.

  • Publication number: 20090113660
    Abstract: An improved pickup or intake hood for use in regenerative air flow road and pavement sweeper vehicles includes at least one side auxiliary plenums and/or at least one side-to-side plenum adjacent the primary air flow compartment. The auxiliary plenums are attached by appropriate ducting into the regenerative air flow so that any fugitive air and or dust flows from the primary air flow compartment are captured in the auxiliary plenums to minimize fugitive air and/or dust flows into the ambient atmosphere. Dust conduits from shrouded gutter brooms enter a manifold box to allow dust-entrained air flows from one or both gutter brooms to enter into the regenerative air flow to capture dust generated by the gutter brooms.

  • Patent number: 6381803
    Abstract: A vacuum cleaner capable of drawing different current levels in vacuum and blower modes is disclosed. The vacuum cleaner comprises at least one electric motor and an impeller disposed in an impeller housing, the impeller driven by the at least one electric motor. A receptacle has an inlet and an orifice in fluid communication with the impeller housing, wherein the impeller creates a low pressure area in the receptacle thereby drawing air into the inlet. An outlet is in air flow communication with the impeller housing, wherein air from the impeller is expelled through the outlet. A switch is associated with the outlet, wherein the switch has a first position in which a first current may be drawn by the at least one motor and a second position in which a second current, less than the first current, may be drawn by the at least one motor. A device is removably attached to the outlet for directing air.
