Claim:
A floor treatment apparatus comprising: a chassis having a front and a back and with a lower surface, a front surface adjacent the front, a rear surface adjacent the back, a left surface, and a right surface; a first wheel operably interconnected to the lower surface adjacent to the left surface and located closer to the rear surface than the front surface; a second wheel operably interconnected to the lower surface adjacent the right surface and located closer to the rear surface than the front surface; a horizontal platform located within the chassis and positioned directly above an axis extending between the center of the first wheel and the center of the second wheel, the horizontal platform also being positioned closer to a bottommost edge of the left surface and a bottommost edge of the right surface than an uppermost edge of the left surface and an uppermost edge of the right surface, the horizontal platform includes a throttle, an operator presence switch, which interrupts the throttle when not depressed, and a platform switch, which must be engaged in order for the throttle to be effective; a steering wheel operably interconnected to a third wheel located approximately between the left surface and the right surface that allows the chassis to rotate 360 degrees without substantially moving in other directions; and a power plant interconnected to at least one of the wheels.
