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 recovery tank for a surface cleaning apparatus such as an extractor is provided. The apparatus comprises a base positionable on the surface to be cleaned and includes a suction nozzle having a suction inlet in fluid communication with a duct and an exhaust outlet. The recovery tank is mountable to the base and has one or more walls and a bottom surface. The recovery tank includes a tank inlet extending through the bottom surface, wherein the tank inlet is positioned adjacent the base and operatively coupled to the duct outlet when the recovery tank is mounted to the base. A tank air outlet extends through the bottom surface, wherein the tank air outlet is positioned adjacent the base and operatively coupled to the exhaust outlet when the recovery tank is mounted to the base. A tank air outlet tube extends into the recovery tank from the tank air outlet.

The present disclosure relates to a wastewater tank structure and cleaning equipment. The wastewater tank structure includes a tank body and a tank cover assembly. The tank body has an accommodation cavity therein, and an end of the tank body is formed with an opening in communication with the accommodation cavity. The tank cover assembly includes a cover body and at least one flow divider, and the cover body is disposed at an end of the tank body proximate to the opening. The flow divider is in communication with the cover body and the accommodation cavity. The flow divider is configured to divide a fluid stream flowing therethrough into a plurality of fluid streams formed into pairs having paired kinetic energies carried thereby and paired opposing flow directions, such that the kinetic energies of the pairs of fluid streams cancel out.

A surface cleaning apparatus includes at least a recovery system for removing the spent cleaning fluid and debris from the surface to be cleaned and storing the spent cleaning fluid and debris. The recovery system is provided with a recovery tank having a removably strainer that is configured to strain large debris and hair out of the recovery tank prior to emptying the recovery tank.

A mist generating system for a cleaning implement is adapted to generate a finely atomized liquid mist for suppressing dust, allergens, and other airborne particulates. The mist generating system can be adapted to fit many cleaning implements such as vacuum cleaners, wet extraction cleaners, floor mops, and dusters to suppress airborne dust and particulates generated during operation and the cleaning process.

An apparatus may include a first layer that includes a plurality of inlets and a surface feature; a second layer, where the surface feature opposes the second layer; an outlet, and a pattern defined on at least one of the first layer and the second layer, where the pattern defines a suction path from each inlet of the plurality of inlets to the outlet.

An extraction cleaner includes a supply tank, a recovery tank, a pump, a suction source, a base configured to support the suction source and the pump, an external hose, and a hose attachment assembly. The hose attachment assembly has a suction conduit extending from a suction inlet connected to the proximal end of the hose to a suction outlet in fluid communication with the recovery tank. The suction conduit is removable from the base with the hose. The hose attachment assembly also has a fluid coupling which is removable with the suction conduit. The fluid coupling extends from a coupling inlet in fluid communication with the pump to a coupling outlet coupled to a supply tube having one or more portions carried within the suction conduit. The proximal end of the hose is at least partially nested adjacent the base when the suction conduit is coupled to the base.

A robot vacuum cleaner includes a main body that moves along a surface, draws in dust from the surface, filters the dust, and discharges air. A water tank is detachably mounted on a lower surface of the main body, and a damp cloth is mounted to the water tank. The water tank stores water in a filling space and supplies water from the filling space through a water supply unit mounted on a lower surface of the water tank to the damp cloth. An air inlet is formed on an upper surface of the water tank. An air inflow member selectively opens the air inlet to allow outside air to flow into the filling space when the main body moves, and closes the air hole when the main body stops moving.

A surface cleaning apparatus such as an extractor has a liquid delivery system, a separator, a collection chamber in communication a the separated element outlet of the separator, and a separated liquid collection container downstream from the collection chamber.

A surface cleaning apparatus includes an upright body and a base adapted for movement across a surface to be cleaned, a fluid delivery system, and a recovery system. The surface cleaning apparatus can be configured to clean multiple surfaces, including hard and soft surfaces, and for different cleaning modes, including wet cleaning, dry vacuum cleaning, and self-cleaning. Methods for self-cleaning a surface cleaning apparatus are also provided.
