Floor cleaning apparatus
First Claim
1. A floor cleaning apparatus comprising:
- a chassis having a forward end and a rearward end;
a plurality of floor engaging wheels supporting said chassis above a floor, wherein at least one of said floor engaging wheels is rotatably driven to propel said chassis along the floor, and wherein at least one of said ground engaging wheels is steerable by an operator supported by said chassis;
at least one first tank supported by said chassis for holding a cleaning solution;
at least one second tank supported by said chassis for holding recovered cleaning solution;
at least one downwardly directed spray nozzle supported by said chassis proximal said chassis forward end and in fluid communication with said at least one first tank, wherein said at least one spray nozzle sprays cleaning solution from said at least one first tank onto the floor;
at least one ground engaging agitation brush disposed rearwardly of said at least one spray nozzle for agitating the cleaning solution sprayed onto the floor; and
at least one vacuum shoe supported by said chassis rearwardly of said at least one agitation brush, and in fluid communication with said at least one second tank, wherein cleaning solution drawn into said vacuum shoe is deposited into said at least one second tank.

Abstract
A cleaning apparatus having a cleaning system including at least one downwardly directed spray nozzle is supported by the chassis proximal the chassis forward end and in fluid communication with at least one cleaning solution tank. The at least one spray nozzle sprays cleaning solution from the tank onto the floor. At least one ground engaging agitation brush is disposed rearwardly of the at least one spray nozzle for agitating the cleaning solution sprayed onto the floor. At least one vacuum shoe is supported by the chassis rearwardly of the at least one agitation brush, and in fluid communication with the at least one recovery tank, wherein cleaning solution drawn into the vacuum shoe is deposited into the at least one recovery tank. In one embodiment the apparatus is drivable. In another embodiment, the apparatus includes a second cleaning system including a vacuum squeegee.
