Abstract: A mobile floor scrubber sweeper includes operator and engine compartments, clean solution and reclaimed dirty solution tanks, and a clean solution delivery system for applying clean solution to a floor ahead of a pair of counter-rotating cylindrical scrub/sweep brushes. Also included are a debris hopper coupled to a first lift system for moving the debris hopper between an operating position within the scrubber sweeper and an elevated aft position for discharging debris/dirty solution into an external debris container, and a rear squeegee coupled to a second lift system for independently moving the rear squeegee from a lowered, floor engaging, operating position to an elevated non-use position to facilitate squeegee inspection, adjustment, maintenance or replacement, without moving the debris hopper. The hopper and squeegee lift systems operate independently of one another, and the hopper lift system is compatible with standard high, i.e., sixty (60) inch, debris containers.

Abstract: A mobile floor cleaning machine has a clean water system with a reservoir for applying water to a floor during cleaning. The floor cleaning machine includes an ozone source which generates ozone in liquid form and introduces the liquid ozone directly into the circulating water for eliminating pathogens in the circulating water. The ozone is generated continuously and essentially instantaneously by the ozone source and destroys most bacteria, virus, fungus and mold in the circulating water at room temperature, while decaying harmlessly to oxygen within the water and producing fewer by-products than chemical sanitizers and having essentially no environmental impact.

Abstract: In a mobile floor sweeper/scrubber, a closed hydraulic system directs hydraulic fluid, or oil, to power various subsystems, such as the drive, steering, sweeping, scrubbing, etc., subsystems, which results in heating of the hydraulic fluid to an elevated temperature. The heated hydraulic fluid is provided to a heat exchanger, to which is also providing the scrub water for heating the water prior to application to the floor for improved, more efficient cleaning of the floor. This arrangement allows for the use of higher scrub water temperatures without using a dedicated system limited to the generation of higher scrub water temperatures, or without operating the sweeper/scrubber's drive motor at elevated temperatures higher than its specified normal operating temperature. The use of heated or ambient scrub water can be selected as desired by the sweeper/scrubber operator.

Abstract: A method for treating flooring not designed for sanding and having a multi-layer wax finish reduces the frequency of stripping the wax layers down to the flooring and recoating the flooring in carrying out periodic maintenance on the flooring. A mobile floor treating machine includes at least one rotating brush which is driven at a first circular speed x for cleaning the flooring and is driven at a second circular speed y for removing the two uppermost layers of wax, where y?2x. The top remaining wax layer is then cleaned with the brush operating at the original circular speed x. Two layers of wax are then sequentially applied to the top remaining wax layer in replacing the two removed layers of wax on the floor and restoring the flooring to its original finish. The brush may be operated at 800-1500 RPM for burnishing and polishing.

Abstract: A cleaning machine for floors and carpets includes a vacuum pick-up in front of the machine for suctioning loose material and debris off the floor. A microfiber cleaning assembly is mounted beneath the machine for cleaning the floor following the vacuum pick-up. The microfiber cleaning element may be motor driven. A source of solution delivers a controlled amount of solution or water to moisten the microfiber cloth. A vacuum motor provides suction to the forward vacuum pick-up, routes the suctioned air through a filter, and the filtered air is then delivered to an air diffuser to dry any residual moisture behind the microfiber cleaning assembly. The microfiber cleaning assembly may have two offset pads driven by a reciprocating or oscillating drive, or one or two cylindrical rollers for receiving and securing the microfiber fabric in the form of a sleeve.
