A riding floor scrubber (10) is disclosed having a relatively narrow cleaning width for passing through relatively narrow passages such as conventional doorways. The riding floor scrubber (10) includes a recovery tank (16) that is vertically and laterally arranged and removably attached to the back of a clean solution tank (14). The clean solution tank (14) includes spaced parallel side portions (26, 28) and the recovery tank (16) extends between the rear ends of the side portions (26, 28). The recovery tank (16) is secured by first and second brackets (42) that extend into recesses (44) on the clean solution tank (14), with the bottom of the recovery tank (16) including a lip portion (46) resting on a metal plate (20) of a chassis (18), with a battery pack (52) being supported on the plate (20) between the side portions (26, 28) of the clean solution tank (14). The clean solution tank (14) includes a middle portion (29) and a lower portion (24) integrally extending forwardly of the middle portion (29), with the left side portion (26) extending to the same longitudinal extent as the lower portion (24). The clean solution tank (14) is molded into a complex shape to maximize capacity, with the bottom of the clean solution tank (14) being recessed to receive the chassis (18) of a tricycle type to define triangular-shaped volumes (88).
