A wet-dry vacuum device assembly comprises a housing and a motor-fan assembly mounted in the housing. The motor-fan assembly is arranged to generate an air flow along an airflow path between a dirty air inlet and a clean air exhaust. The wet-dry vacuum device comprises a tank positioned along the airflow path and arranged to capture liquid entrained in the dirty air flow. The wet-dry vacuum device further comprises a removable pump accessory mountable to the housing. The removable pump accessory comprises pump and a fluid inlet in fluid communication with the tank and the pump. A fluid outlet is in fluid communication with the pump and connectable to an exterior hose. The pump is arranged to move captured liquid in the tank from the fluid inlet to the fluid outlet.

A portable surface cleaning apparatus for a floor surface includes a main housing assembly adapted to be hand carried by a user, the main housing assembly carrying a fluid delivery system adapted for storing cleaning fluid and delivering the cleaning fluid to the surface to be cleaned, and a fluid recovery system adapted for removing the cleaning fluid and debris from the surface to be cleaned and storing the cleaning fluid and debris that was recovered, the main housing assembly comprising a base housing, a supply tank received on the main housing assembly, a recovery tank received on the main housing assembly separately from the supply tank.

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 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 handheld extraction cleaner includes a unitary body provided with a carry handle, and further provided with a supply tank, a recovery tank, and a suction source, all of which are carried on the unitary body. The various components of the extraction cleaner can be arranged for a balanced weight in hand. The supply and recovery tanks are configured to optimize the usable volume within the tanks, among other functions. A powered cleaning head including a removable brushroll is provided on the unitary body.

A surface cleaning apparatus is provided with a housing including an upright assembly and a base assembly moveably mounted to the upright assembly, the upright assembly forming a stalk, a fluid container provided on the housing, a fluid distributor provided in the base assembly in fluid communication with the fluid container, a working air path through the housing, a recovery container provided on the housing and defining a portion of the working air path, a suction source provided on the housing and defining a portion of the working air path, a suction nozzle provided on the base assembly.

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 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 combination of a floor cleaner and a cleaning tray. At least a portion of a base of the floor cleaner is received by a reservoir of the cleaning tray. The floor cleaner further including an upright portion movable between an inclined use position and an upright storage position. The brushroll is powered by a brushroll motor. The brushroll motor includes a control circuit that controls the brushroll. The control circuit has a first switch that is open when the floor cleaner is in the upright position and closed when the floor cleaner is in the inclined use position. The second switch is in parallel with the first switch. The second switch is opened in response to the portion of the base being removed from the cleaning tray and the second switch is closed when the portion of the base is in the cleaning tray.
