Abstract:

A floor scrubber includes a forward cylindrical brush with adjustable down pressure. The cylindrical brush is sprayed uniformly with a controlled amount of water or solution and moves debris forward with a direct propelling action into a collection hopper. A set of three disc brushes is located behind the cylindrical brush, followed by a suction liquid recovery device for suctioning spent solution. A control system allows independent use of the forward cylindrical brush, or the rear disc brush set, or all brushes. A floor-engaging flap having a central opening extends transverse of the machine behind the cylindrical brush to channel water from the cylindrical brush to the disc brush set and then to the suction recovery device.
