ABSTRACT:
Apparatus (10) is disclosed including an interchangeable brush (88) and either a removable vacuum shoe (38) for soft floor surfaces or removable squeegee and carriage assemblies (56, 68) for hard floor surfaces. A spindle (32) is rotatably mounted in the chassis (18) and includes first and second arms (36, 52). The first arm (36) is attached to a sleeve (34) for removably and pivotally receiving a pivot pin (40) of the vacuum shoe (38). The second arm (52) includes an elongated slot (54) which slideably receives a follower pin (82) of a crank arm (80) of the carriage assembly (68). The spindle (32) is rotated by an integral lever (44) pivotally connected to a linkage (46) having its opposite end pivotally connected to a second, pivotable lever (26). A bracket (20) is pivotable with a handle (16) and abuts with the second lever (26) to support the chassis (18) by the vacuum shoe (38) or the roller (86) of the carriage assembly (68) such that the brush (88) is spaced from the floor surface when the handle (16) is in a transport position. The free end of a screw (30) threadably secured in the chassis (18) abuts with the second lever (26) when the handle (16) is in operating positions to adjust the height of the brush (88) relative to the floor surface.
