A cleaning device and methods for cleaning are provided. In one embodiment, the cleaning device includes a head assembly, a body assembly, and a handle assembly. The cleaning device also includes components that enable the cleaning device to operate in dry cleaning modes and wet cleaning modes. Dry cleaning modes can employ a vacuum assembly, including a motor, tubing, and a fluid recovery tank in order to draw in debris and waste into a fluid recovery tank. Wet cleaning modes can further employ a fluid supply tank, a pump, and tubing in order to supply fluid to a brushroll to aid in a cleaning process.

A nozzle for a cleaner has a nozzle housing, and first and second rotation cleaning units arranged on a lower side of the nozzle housing and spaced apart from each other. Each of the first and second rotation cleaning units includes a rotation plate coupled to a mop. The nozzle includes a first driving device having a first driving motor to drive the first rotation cleaning unit and a second driving device having a second driving motor to drive the second rotation cleaning unit. Further, the nozzle has a water tank mounted on the nozzle housing to store water. The nozzle housing includes driving unit covers arranged to surround each of the driving devices. At least one of the driving unit covers includes a first protruding surface, and a second protruding surface positioned higher than the first protruding surface.

A surface cleaning apparatus such as an extractor has a fluid flow path extending from a dirty fluid inlet head to a clean air outlet. The fluid flow path upstream of the separation stage comprises a removable portion.

A nozzle for a cleaner includes a nozzle housing that has a suction flow path that allows air containing dust to flow therethrough. The nozzle also includes a driving device including a driving motor. Further the nozzle includes a rotation cleaning unit including a rotation plate which is connected to the driving device at a lower side of the nozzle housing. The nozzle also includes a mop attached to a lower side of the rotation plate. In addition, the nozzle includes a water tank mounted on an upper side of the nozzle housing and configured to store water. The water tank is separable from the nozzle housing. An upper side wall of the water tank forms an upper surface of the nozzle when the water tank is mounted on the nozzle housing, and a portion of a bottom wall of the water tank is configured to surround the driving device.

A surface cleaning apparatus includes a housing having a base and a partition, a supply tank removably mounted on the housing, and a recovery tank removably mounted on the housing. The tanks can be mounted within voids defined by portions of the housing. Latches can secure the tanks to the housing.

Systems and method for self-cleaning extraction cleaners, including upright or robot extraction cleaner are provided. In one system, a tray can be provided for docking the extraction cleaner during the self-cleaning mode. The tray may include one or more sprayers for spraying a cleaning fluid toward an agitator of the extraction cleaner. In another system, a nozzle flushing manifold mounted on the nozzle assembly of the extraction cleaner includes a plurality of distributor outlets configured to spray cleaning fluid into the suction pathway.

An extraction cleaner includes a portable extractor and a base adapted to be moved to perform a cleaning operation on a floor surface when the portable extractor is operably mounted to the base. The portable extractor includes a recovery tank assembly provided on the housing adjacent to the recovery tank assembly.

A surface cleaning apparatus includes a housing, a fluid delivery system including a supply tank removably mounted on the housing and a fluid distributor, a fluid recovery system having a recovery tank removably mounted on the housing, an extraction nozzle, a motor/fan assembly, and a supply tank receiver provided on the housing for receiving the supply tank and comprising a void at least partially defining a seat for the supply tank.

A nozzle for a cleaner has a nozzle main body including an intake channel to suction air. The nozzle includes first and second rotary cleaning units spaced apart from each other in a lateral direction under the nozzle main body. Each of the first and second rotary cleaning units includes a rotary plate coupled to a dust cloth. The nozzle further includes a first driving device to drive the first rotary cleaning unit and a second driving device to drive the second rotary cleaning unit. The nozzle includes a water tank to store water. Further, the nozzle has a water supply channel to supply water in the water tank to the rotary cleaning units. The nozzle has a water pump and a pump motor to drive the water pump to pump the water to the dust cloth.
