International ClassesA47L 007/00A47L 009/04 A47L 011/18 AbstractA floor scrubbing machine for tile and other hard surface floors has a low enough profile height that it can be operated bodily under furniture or equipment such as, for example, seats in fast food stores. This floor scrubber has three principle functioning components, comprising a tank for cleaning solution and means to apply that solution to the floor, a powered scrub brush to agitate the solution on the floor, and a vacuum pickup squeegee system which dries the floor after scrubbing by removing spent solution from the floor to an on board tank. Floor scrubbers are known which comprise the three above elements, but are too tall to operate under the seats of fast food stores, except with a remote wand attachment which is cumbersome and slow. Other floor scrubbers are known which are low enough to operate bodily in such places but lack a vacuum pickup squeegee system for drying the floor, and leave a hard surface floor unacceptably wet, or require following operations to dry it. The present invention overcomes the shortcomings of these prior art floor scrubbers.Field of SearchWith liquid or other cleaning material application to workManipulatable nozzle with flexible conduit connection to portable power and/or material supply unit, e.g., window washer With liquid and/or deflection type separator With work-contacting carriage or mount, and relatively adjustable nozzle Biased or floating nozzle Rotary work contactor Nozzles Rotary agitator | |
