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.
