The invention relates generally to floor surface treatment apparatus, more particularly to such apparatus embodied, for example, in a floor scrubber having a rotary brush or brushes for scrubbing the floor or a rotary pad for waxing and/or polishing the floor.
The invention is in a category similar to that of the coassigned U.S. patent Ser. No. 09/934,146 of William R. Stuchlik filed Aug. 21, 2001, published May 2, 2002 as Publication No. U.S. 2002-0050014-A1, which is incorporated herein by reference. The invention has been developed because of the need becoming recognized for apparatus in which the floor surface treatment unit (e.g. brush, brushes, pad) may be differently positioned, as for variation of its pressure on the floor during operation, for transport of the apparatus, and for facilitating servicing of the floor surface treatment unit.
