Abstract: A liquid extraction cleaner includes a recovery tank mounted to the forward end of a cleaner housing with a suction nozzle and conduit on a front face of the recovery tank connected to an inlet opening in the recovery tank. A vacuum source is connected to the recovery tank through a working conduit integrally formed in the recovery tank, the recovery tank removably received in a cavity on a front portion of the cleaner housing, and including a pivotal connection and latch for securing the tank to the housing. A removable cleaning fluid supply tank is mounted to a rear portion of the cleaner housing, having depressions formed thereon to aid removal, and retained thereon by the seal between the supply tank and the housing. A recharging base for the cleaner has a guide pin and electrical connector for aligning to form an electrical connection with a battery charging circuit.

Abstract: The invention relates to dirt separator module comprising a dirt-separation housing having an inlet and an outlet opening and defining a cyclonic airflow separator, and a suction source fluidly connected with the dirt-separation housing. A separator plate and a cylindrical wall of the dirt-separation housing form a toroidal cyclonic airflow chamber in the dirt-separator for aiding in the separation of dirt from a suction airstream developed by the suction source. The separator plate has an outer diameter smaller than the inner diameter of the cylindrical wall of the dirt-separation housing, creating a gap between the outer edge of the separator plate and the inner wall of the dirt tank. A further embodiment includes dual cyclonic separators fluidly connected through a filter assembly. A further embodiment includes a cyclonic separator in the form of a tangential helical ramp.
