Abstract
A self-propelled floor cleaning machine or scrubber of the walk-behind type includes a one-piece molded main body incorporating an integral solution tank. The main body includes a central cavity in which is received a one-piece molded secondary body defining a recovery tank. The main body receives the secondary body in an interlocking fashion such that the entire unit is self-supporting, such that the use of gaskets or sealers between the tanks and other components is eliminated. The main body is supported on a steel frame which also supports the batteries, cables, wheels, brushes, squeegee, and the like (frame components). The main body fits over the frame components and together with the secondary body provides a water shedding cover therefore.
