    Abstract: In one aspect of the invention, a portable floor care system with manually interchangeable AC and DC vacuum motor head assemblies for use in cleaning hard surface flooring may include: a reservoir defining an interior space operable to hold a cleaning liquid; a spigot fluidly connected to the reservoir interior space, the spigot manually adjustable through a range between a fully open position and a fully closed position, whereby when the reservoir contains a cleaning liquid, a user may dispense and regulate the flow of the cleaning liquid from the reservoir through the spigot by manually adjusting the spigot; a vacuum recovery tank; an AC vacuum motor head assembly and a DC vacuum motor head assembly manually and interchangeably fluidly connectable to the vacuum recovery tank; and a DC power supply assembly. In another aspect of the invention, a portable floor care system with manually interchangeable AC and DC vacuum motor head assemblies for use in cleaning hard surface flooring may include a reservoir assembly including: a reservoir defining an interior space operable to hold a cleaning liquid; a wheeled chassis; and a spigot fluidly connected to the reservoir interior space, the spigot manually adjustable through a range between a fully open position and a fully closed position, whereby when the reservoir contains a cleaning liquid, a user may dispense and regulate the flow of the cleaning liquid from the reservoir through the spigot by manually adjusting the spigot. The portable floor care system may further include: a vacuum recovery tank manually and removably positionable on the reservoir assembly; an AC vacuum motor head assembly and a DC vacuum motor head assembly interchangeably manually and removably positionable on the vacuum recovery tank in fluid communication with the vacuum recovery tank; and a DC power supply assembly manually and removably positionable on the reservoir assembly.

    Abstract: A floor working machine includes a body frame (1), an electric drive unit (29), a pad unit including a first pad (21) and a second pad (21) having polishing surfaces (21a) for contacting a floor surface, the first pad and second pad being opposed to each other, and a pad control mechanism (50) for controlling the pad unit by using drive of the electric drive unit. The pad control mechanism (50) controls the first pad (21) and second pad (21) such that the first pad and second pad reciprocate, with the respective polishing surfaces (21a) contacting the floor surface, in a first direction (A) in which the first pad and second pad approach each other and in a second direction (B) in which the first pad and second pad move away from each other. A guiding device (23, 25) guides the first pad and second pad in reciprocating movement such that the first direction and second direction are linear and parallel to the floor surface.

    Abstract: A cleaning device for smooth floor surfaces has a housing having a working chamber and a drive chamber. First and second cleaning rollers are rotatably supported in the working chamber and extend transversely to a working direction of the cleaning device substantially across an entire width of the cleaning device. A drive is arranged in the drive chamber and drives the first and second cleaning rollers about a horizontal axis of rotation. The first and second cleaning rollers are height-adjustably arranged in the housing such that an adjusting device acts on the first and second cleaning rollers and moves them into a working position or into a parking position, respectively. The first and second cleaning rollers have a mantle surface projecting in the working position downwardly past a bottom plate of the housing to act on a floor surface.
