摘要： A cleaning apparatus for cleaning a surface in which cleaning solution is distributed to the surface and substantially simultaneously extracted along with the dirt on the surface in a continuous operation as it moves along the surface is provided. The cleaning apparatus includes a housing and a liquid distribution system operatively associated with the housing. The liquid distribution system includes a fluid source providing a supply of the cleaning solution and a distributor fluidly connected to the fluid source for distributing the cleaning solution to the surface. A liquid recovery system is operatively associated with the housing and includes a suction nozzle and a recovery tank removably mounted to the housing and in fluid communication with the suction nozzle. A suction source is in fluid communication with the suction nozzle for applying suction to draw the cleaning solution and dirt from the surface through the suction nozzle and into the recovery tank. A filter system is provided on the housing and in fluid communication with the recovery tank for filtering the recovered cleaning solution to be reused. The filter system includes a first filter provided on a filter support mounted to the recovery tank for filtering particles from the cleaning solution and dirt, and a second filter fluidly connected between the recovery tank and the distributor for filtering particles from the cleaning solution and dirt of a smaller size than the particles filtered from the first filter.
