An accessory tool according to the present invention comprises a recovery tank assembly for removing fluid and dirt from a surface to the cleaned and storing the recovered fluid and dirt. The recovery tank assembly comprises a suction nozzle in fluid communication with a recovery tank. The accessory tool further comprises a fan/turbine assembly including a turbine-driven suction fan for generating suction at the suction nozzle, which draws liquid and air into and through the accessory tool. The turbine-driven suction fan can be magnetically coupled with the turbine. The accessory tool can further comprise a fluid dispensing assembly for storing and distributing fluid to the surface to the cleaned. The fluid dispensing assembly can comprise a turbine-driven fluid pump. The accessory tool can further comprise an agitator assembly that can be moved from a use to a non-use orientation to allow the accessory tool to alternately be used for scrubbing the surface to the cleaned and for extracting fluid from the surface to be cleaned. The recovery tank can further comprise a rotating outlet conduit with an inlet opening that will have an upward orientation when the recovery tank is tilted.
