ABSTRACT:
A cleaning apparatus for cleaning a surface in which cleaning solution is dispensed to the surface and substantially simultaneously extracted along with the dirt on the surface in a continuous operation is provided. In one aspect of the invention, the cleaning apparatus includes a housing and a recovery tank removably mounted to the housing. A solution tank for supplying a flow of cleaning solution to the surface is removably mounted to the housing. A suction nozzle is secured to the housing and is in fluid communication with the recovery tank. A suction source is in fluid communication with the suction nozzle for generating suction to draw dirt and liquid through the suction nozzle and into the recovery tank. A first latch is operatively connected to the solution tank to releasably latch the solution tank to the housing and a second latch is operatively connected to the recovery tank to releasably latch the recovery tank to said housing, wherein the second latch is in close proximity to the first latch.
