Abstract:
A liquid extraction cleaning device comprises a main unit, a liquid pump, a flexible hose, and a hand tool. The main unit comprises a vacuum pump. The hand tool comprises a vacuum inlet port, an agitator, a spray nozzle, and a grip portion. The vacuum inlet port of the hand tool is operatively connected to the vacuum pump via the hose passageway in a manner such that the vacuum pump is capable of drawing fluid through the vacuum inlet port and into the hose passageway. The spray nozzle is operatively connected to the liquid pump in a manner such that the liquid pump is capable of forcing liquid out of the spray nozzle.
Abstract:
A portable power and water supply for hard surface or carpet cleaners is disclosed. The portable power and water supply can include a portable platform with a fresh/waste water tank and two or more power connectors that can be coupled to separate power sources. The fresh/waste water tank can have an internal bladder that separates fresh cleaning water from returned waste water. The fresh/waste water tank can facilitate operation of cleaning tools (e.g., hard surface cleaners and/or carpet cleaners) in buildings with limited or widely spaced water supplies, without the need for long hoses. The power connectors can be coupled to wall power to direct power to the cleaning tools.
Abstract:
The invention relates generally to the conditioning of bowling lanes, and, more particularly to an apparatus and method for automatically applying a predetermined pattern of dressing fluid along the transverse and longitudinal dimensions of a bowling lane.
Abstract:
An apparatus and method for cleaning fabrics, floor coverings, and bare floor surfaces utilizing a soil transfer cleaning medium is disclosed. A method of mechanically removing soil from a surface intended to be cleaned includes the steps of successively and repeatedly: wetting a portion of a cleaning medium with a cleaning liquid; extracting any soil and at least some of the cleaning liquid from the previously wetted portion of the cleaning medium; and wiping the surface intended to be cleaned with the portion of the cleaning medium so as to transfer soil from the surface intended to be cleaned to the cleaning medium. Portable and vehicle-based devices may be utilized to practice the method of cleaning.
Abstract:
An indoor/outdoor cleaning system includes a portable pressurized housing for containing cleaning fluids (water, chemicals, and mixtures thereof). Multiple hoses connect the interior of the housing with a cleaning wand. The wand includes a handle, a hollow trunk portion and a cleaning head. The multiple hoses have outlets adjacent the cleaning head for feeding water, cleaning chemicals, or surface treating fluids thereto. The outlets open adjacent a cleaning pad, which pad, which pad is attached to the cleaning head via a mechanism that allows the pad to move either in a linear or sinusoidal (rocking) motion or the combination of both motions thereof. A variety of cleaning pad accessories (brush, sponge, sanding pad, buffing pad, etc.) can be optionally attached to the cleaning pad based on the type of surface to be cleaned or treated. A suction conduit, disposed in the cleaning head, functions to draw used fluids away from the surface for safe disposal thereof.
Abstract:
A floor cleaning machine includes a vacuum pick-up in front of the machine for suctioning loose material and debris off the floor. A micro fiber pad assembly is mounted beneath the machine for cleaning the floor following the vacuum pick-up. The micro fiber pad may be motor driven. A source of solution delivers a controlled amount of solution or water to moisten the micro fiber pad. A vacuum motor provides suction to the forward vacuum pick-up, routes the suctioned air through filter, and the filtered air is then delivered to an air diffuser at the rear of the machine to dry any residual moisture behind the micro fiber pad.
Abstract:
As the cleaning machine travels along the lane from the foul line toward the pin deck area, cleaning liquid is sprayed onto the lane surface in periodic discharges of relatively short duration. A soft, thin web of cloth material immediately behind the spray nozzles is looped under a transverse cushion or backup member and is pressed against the wetted lane surface to spread and meter out the liquid into a thin film that passes beneath the cushion as a bead or shallow pool of the liquid is pushed along ahead of the cushion. The film is subsequently lifted entirely off the lane surface to remove all traces of moisture, oil, and grime by a combination squeegee and vacuum head assembly immediately behind the spreading web assembly. Programmable controls on the machine permit the cleaning functions to be carried out in relation to the position of the machine on the lane.
Abstract:
A hard surface cleaning appliance includes a hood separating an interior space within the hood from an exterior space outside the hood. The hood includes a top wall as well as a solid outer side wall and an inner side wall depending from the top wall. The outer side wall includes a lower edge that is adapted to contact a surface to be cleaned, while the inner side wall includes a lower edge spaced inwardly of the outer wall that is elevated above the surface to be cleaned. A vacuum passage is formed between the inner side wall and the outer side wall, and a vacuum source is fluidly connected to the vacuum passage. A spout within the interior space is fluidly connected to a cleaning liquid source. The appliance may include a vacuum relief passage extending through the hood and thereby fluidly connecting the interior space with the exterior space. A vacuum relief valve can prevent fluids from exiting the interior space through the vacuum relief passage, but allow fluids to enter the interior space through the vacuum relief passage. Also, the outer wall may include a solid outer depending side wall and a solid skirt mounted on a lower edge of the outer depending side wall, the skirt adapted to contact the surface to be cleaned.
