Floor scrubber having interlocking tanks
First Claim
1. A floor washing machine for cleaning a floor comprising:
- a chassis;
an on-board power system supported by said chassis;
at least one wheel powered by said power system and mounted to said chassis for supporting, carrying, and moving said chassis;
at least one brush powered by said power system and attached to said chassis for scrubbing and applying a cleaning solution to the floor;
a one-piece molded main body supported on said chassis and covering said power system, said main body having a central cavity and an integrally formed solution tank for holding the cleaning solution;
a one-piece molded secondary body defining a recovery tank, said secondary body receivable in and supported by said central cavity in an interlocking fashion;
a solution application system for transferring the solution from said solution tank to said at least one brush; and

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.

5. A self-propelled, walk-behind floor scrubber comprising:
-
a frame supported by a powered wheel; a rotatable brush supported on a front portion of said frame and adapted to contact and clean a floor surface; a one-piece molded housing supported on said frame, said one-piece molded housing having an integrally formed solution tank for storing a cleaning solution and a central opening, said one-piece molded housing further defining an interior cavity; a one-piece molded body defining a recovery tank, said one-piece body receivable in and supported by said central opening, said central opening including inwardly extending ledges and said one-piece body including complementary inwardly extending surfaces adapted to interlockingly engage said ledges to form a water-shedding cover about said interior cavity; a solution application system in communication with said brush and said solution tank for supplying the cleaning solution to said brush from said solution tank for application onto the floor; and a suction system in communication with the floor and said recovery tank for transferring spent cleaning solution on the floor to said recovery tank as the floor scrubber moves in the direction of said brush. - View Dependent Claims (6)
