  • Publication number: 20210030237
    Abstract: A multi-functional cleaning and floor care system may have: a fresh liquid reservoir; a vacuum assembly including a vacuum recovery tank and a vacuum motor assembly; a wheeled chassis configured to support at least one of the fresh liquid reservoir and the vacuum recovery tank; and a spigot fluidly connected to the fresh liquid reservoir, with the spigot adjustable between a fully open position and a fully closed position. The system also may have: a liquid spreader assembly connected to at least one of the fresh liquid reservoir, the vacuum assembly, and the wheeled chassis, with the liquid spreader assembly including a frame and a spreader pad; and a squeegee head assembly connected to at least one of the fresh liquid reservoir, the vacuum assembly, and the wheeled chassis, with the squeegee head assembly fluidly connectable to the vacuum recovery tank.

  • Publication number: 20140130295
    Abstract: A particular wide-area vacuum/squeegee-head floor cleaning tool, in accordance with the principles of the invention, includes: an elongated frame including a top, a front, a back, a first end, a second end, and a soil uptake opening positioned between the first and second ends; at least one squeegee blade at the front and extending between the first and second ends; at least one squeegee blade at the back and extending between the first and second ends; a first wheel at the first end; a second wheel at the second end; and a third wheel at the soil uptake opening. The first, second, and third wheels are constructed and arranged to support the elongated frame above a floor surface when the squeegee blades at the front and back are in contact with the floor surface in a deflected orientation and vacuum suction is applied to the floor cleaning tool by the vacuum source.
