Benefits of technology

[0047] It is another aspect of the present invention to provide a cleaning apparatus that is safe and comfortable to use. More specifically, one embodiment of the present invention includes an operator platform. This platform allows the operator to stand on the device during the treatment operation, thus increasing productivity and lowering the chances of injury or fatigue to the operator. It another embodiment of the present invention, a seat is provided wherein the operator may comfortably sit while completing his or her task. Other safety and comfort features such as rails, pads, and belts, may be provided depending on the needs of the operator.
[0048] It is still another aspect of the present invention to provide a counter balance mechanism that enables the deck used in accordance with embodiments of the present invention to float on an uneven floor/surface with a substantially consistent downward force. In one embodiment, a deck is attached to the chassis of the present invention through a counter balance mechanism that utilizes a unique geometry along with springs to enable the deck to continually adjust itself, thereby obviating the need for an electronic controller or cont...

Embodiment Construction

[0097] Referring now to FIGS. 1-34 an apparatus 2 for cleaning or otherwise treating a floor surface is shown. More specifically, one embodiment of the present invention includes a chassis 8 with a platform 4 that is adapted to support the weight of an operator 6, thus increasing the efficiency of the entire floor treatment operation. In addition, various cleaning or floor treatment components maybe interconnected to the bottom surface 10 of the chassis, such as brushes 12, scrubbers 14, squeegees 16, vacuum shoes, etc.

[0098] The chassis 8 also includes a plurality of wheels 18 operably interconnected to the bottom surface 10 to enable steering and provide stability. It is contemplated that the operator 6 will stand on the platform 4 and steer the apparatus 2 with either a steering wheel 20 or other type of steering mechanism, such as a joy stick 22. Such an embodiment of the present invention enables the floor surface to be cleaned or otherwise treated more efficiently, since the ...
