1. Apparatus for cleaning both hard and soft floor surfaces comprising, in combination:

  • a chassis having a first end and a second end;

    means for movably supporting the first end of the chassis on the floor surface;

    a brush adjacent to the second end of the chassis for engagement with the floor surface;

    a vacuum shoe of a generally rigid construction for extraction of solution from soft floor surfaces;

    means for removably securing the vacuum shoe relative to the chassis adjacent the second end of the chassis;

    a carriage assembly for movably supporting the second end of the chassis on the floor surface;

    means for removably securing the carriage assembly to the chassis adjacent the brush;

    means for moving one of the vacuum shoe and the carriage assembly for supporting the second end of the chassis to change the relative height of the brush from the floor surface, with the chassis being supported on the floor surface by the movably supporting means and one of the vacuum shoe and the carriage assembly when the brush engages the floor surface, with the movably supporting means and the vacuum shoe supporting the chassis when cleaning soft floor surfaces and the movably supporting means and the carriage assembly supporting the chassis when cleaning hard floor surfaces;

    a squeegee assembly for removing solution from hard floor surfaces; and

    means for removably securing the squeegee assembly to the second end of the chassis for engaging the squeegee assembly with the floor surface when the chassis is supported on the floor surface by the movably supporting means and the carriage assembly, with the squeegee assembly providing minimal support to the chassis when the squeegee assembly engages the floor surface and removes solution from the floor surface.
