A surface maintenance machine is provided having a maintenance head assembly positioned substantially within an envelope of the machine. The maintenance head assembly has at least one maintenance tool attachable thereto. The machine also includes a tool eject mechanism positioned below an upper surface of the body. The tool eject mechanism can generate a drop force sufficient to overcome the force between the maintenance tool and the maintenance head assembly. The tool eject mechanism can have an eject button extending above the upper surface of the deck. The eject button can be actuable by at least a portion of the upper surface of the body of the machine when the maintenance head assembly is raised toward the upper surface of the body of the machine beyond a transport position into a tool eject position. When actuated, the tool eject mechanism can eject the maintenance tool from the maintenance head assembly

A floor cleaning machine having an intelligent system including a recovery tank sub-assembly, a vacuum fan sub-assembly, a solution tank sub-assembly, wherein the solution tank sub-assembly preferably includes a secondary electrochemical cell, a solution flow sub-assembly, a control console sub-assembly, a frame and wheel sub-assembly and/or a frame and transaxle sub-assembly, a scrub head sub-assembly, a scrub head lift sub-assembly, a squeegee sub-assembly, a solution flow sub-assembly, and an intelligent system associated with at least one of the above-identified sub-assemblies, wherein the intelligent system at least one of selectively gathers, obtains, monitors, stores, records, and analyzes data associated with components of the floor cleaning machine assembly, and at least one of controllably communicates and disseminates such data with at least one of another system and user.

The present invention relates to systems and methods for cleaning materials, such as flooring and upholstery. In some cases, the systems and methods use an electrolytic cell to electrolyze a solution comprising sodium carbonate, sodium bicarbonate, sodium acetate, sodium percarbonate, potassium carbonate, potassium bicarbonate, and/or any other suitable chemical to generate electrolyzed alkaline water and/or electrolyzed oxidizing water. In some cases, the cell comprises a recirculation loop that recirculates anolyte through an anode compartment of the cell. In some cases, the cell further comprises a senor and a processor, where the processor is configured to automatically change an operation of the cell, based on a reading from the sensor. In some cases, a fluid flows past a magnet before entering the cell.

In some additional cases, fluid from the cell is conditioned by being split into multiple conduits that run in proximity to each other. Additional implementations are described.

A surface cleaning apparatus having an upright assembly, a power source, and a coiled electrical cable. The upright assembly including a frame and a telescoping handle at last partially extending from the frame and movable between an extended position and a contracted position. The coiled electrical cable being provided within a portion of the telescoping handle and configured to uncoil or coil when the telescoping handle is moved between the extended position and the contracted position.

A cleaner head for a cleaning appliance including an agitator rotatable about an axis; a housing having a front side, a rear side, and first and second sides which extend between the front side and rear side, said housing further including a floor facing surface. The housing defines a chamber which at least partially surrounds the agitator, the chamber having a dirty air inlet and a dirty air outlet. A wiper device which extends laterally between the first and second sides of the housing and is positioned on or adjacent the floor facing surface. A floor engaging device extends laterally between the first and second sides of the housing and is positioned on or adjacent the floor facing surface. The floor engaging device includes an absorbent portion. The wiper device and the floor engaging device are positioned rearwardly of the dirty air inlet.

A cleaning robot includes a top cover, a bottom cover formed below the top cover and configured to move by external force, a fixed body provided in the bottom cover, a first opening formed in an upper portion of the bottom cover and a first sensor connected to the fixed body and externally exposed between the top cover and the bottom cover through the first opening.

The cleaning robot includes a housing, a brush roller and a suction device. The housing is provided with a mounting chamber. A debris collecting chamber is communicated with the mounting chamber. The brush roller is pivotally mounted in the mounting chamber and at least a part of the brush roller protrudes from the mounting chamber. The housing is further provided with a debris collecting channel, one end of the debris collecting channel is communicated with the debris collecting chamber, the other end of the debris collecting channel penetrates through the rear end of housing, and the housing is further provided with a first door for opening or closing the debris collecting channel.

A surface cleaning apparatus having a housing, a suction nozzle, a suction source, a steam port, a steam supply system, and a flexible seal. The housing having a cleaning foot and an upper housing operably coupled to the cleaning foot. The suction source being fluidly connected to the suction nozzle by a working air conduit. The steam port having an aperture provided in the cleaning foot. The steam supply system having a steam nozzle with at least a portion that projects through the steam port. The flexible seal being provided at least around the steam nozzle.

A high-power slurry vacuum cart is well suited to collect and contain any slurry or wet residue produced through concrete and other surface processing operations. A multi-horsepower propane engine and propane tank are mounted on a mobile frame, along with a suction pump powered by the propane engine. A slurry containment vessel mounted on the frame has an input in communication with a squeegee and an output coupled to the suction pump. The squeegee may be adapted for floor contact to collect slurry for transfer to the slurry containment tank. The suction pump is directly coupled to the propane engine through a universal joint, thereby obviating the use of belts, chains or pulleys. The output of the pump may optionally be used as an air blower for surface drying, or the like, as well as use as an air blower to assist in emptying the slurry containment tank.

A floor polishing machine for concrete includes a frame with an integrated hydraulic fluid tank, a hydraulic drive system, and a hydraulic pump vacuum system. Further, the machine provides a swivel polishing head that provides abutting contact with a floor and includes a floating ring and rubber skirts that seals the polishing head. The machine provides interchangeable wet and dry vacuum systems for collection of the slurry during wet operation and dust during dry operation. A support member inserts into a receiving sleeve for a choice of wet or dry option. A squeegee system attached to the rear of the apparatus collects slurry and operates to send the slurry to a collection tank. The squeegee lifts out of the way during dry operation.
