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 (1) includes: a main-body housing (2); a suction motor (6), which is housed in the main-body housing and is driven to recover a cleaning liquid from a surface of a cleaning target; a first tank (3), which houses the cleaning liquid to be supplied to the surface of the cleaning target; and a second tank (4), which houses the cleaning liquid recovered from the surface of the cleaning target. One tank of the first tank and the second tank is connected to an upper portion of the main-body housing. The other tank of the first tank and the second tank is connected to a lower portion of the main-body housing and has a lower surface (4A) that opposes a stationary surface on which the surface-cleaning apparatus is disposed.

A surface cleaning apparatus such as an extractor has a liquid delivery system comprising at least one spray nozzle that delivers at least one liquid and an inverted cyclone comprising, when the surface cleaning apparatus is in a floor cleaning orientation, a lower end, a lower end wall, an upper end and an upper end wall, the lower end having a cyclone fluid inlet and a cyclone air outlet and the upper end has a separated element outlet, wherein the cyclone air outlet comprises a treated air outlet conduit and a liquid blocking collar is provided on an outer surface of the treated air outlet conduit below an inlet to the treated fluid outlet conduit. A solid and liquid collection chamber is in communication with the separated element outlet.

Devices for collecting patient excretions utilize existing suction sources and facilitate the cleaning of bedding and/or a patient. Patient excretion collection devices comprise a collection reservoir and a collection wand which are attached to an existing source of suction.

The present disclosure relates to a water tank structure and a vacuum cleaner. The water 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 vacuum cleaner includes a vacuum collection system for sucking up debris from a surface to be cleaned, a fluid delivery system for delivering a cleaning fluid to the surface to be cleaned, and a recovery system for removing spent cleaning fluid and debris from the surface to be cleaned. The fluid delivery and recovery systems can be particularly configured for small area extraction, such as in treating spots and stains on a carpet.

A floor cleaner includes a recovery tank including an inflow path allowing liquid-laden air to enter the recovery tank, an outflow path allowing air to exit the recovery tank; and a chamber for storing liquid. The chamber includes an inlet, a separator that separates liquid from the liquid-laden air, an air outlet, and a float. The float includes a base and a valve with an indicator. The float is moveable between a first position and a second position. In the first position the valve is spaced away from the air outlet and air is allowed to exit the chamber. In the second position the valve is adjacent the outlet and impedes air from exiting the chamber. In the second position the indicator is visible when the chamber is full.

An extractor is provided. The extractor comprises: a base movable along a surface; a handle configured to be gripped by a user to move the base; a nozzle in fluid communication with a suction motor configured to generate a suction airflow through the nozzle; an encoder operable to generate an encoder signal as a first signal based on user-initiated movement of the base along the surface in a forward direction and as a second signal based on movement in a rearward direction; and a controller operatively connected to the encoder and the suction motor, the controller being configured to change a power to the suction motor to a forward power level based on the first signal during operation of the extractor and to a rearward power level based on the second signal during operation of the extractor, wherein the forward power level is less than the rearward power level.

The present invention provides an accessory 20 for use with, and adaptable to be releasably connected to, a vacuum cleaner 1. The accessory 20 comprises a vacuum intake head 21 having a chamber 21a arranged such that when the accessory 20 is connected to the vacuum cleaner 1, the chamber 21a is in fluid communication with the vacuum cleaner 1 and adaptable to receive air and liquid from and around the surface to be cleaned. The accessory 20 further comprises a filtration device 40 adaptable to separate the liquid from the air such that substantially no liquid returns to the vacuum cleaner 1. The accessory 20 can be used with both portable and central vacuum cleaners 1.

A seal assembly for a waste water tank. The seal assembly comprises: a base (2) disposed at a waste water tank (1); a linkage (3) movably disposed at the base (2); a sealing cover (4) connected to the linkage (3) and disposed at a waste water inlet (101) and on a suction opening (102); and a push rod (5) connected to the linkage (3) and used for pushing the linkage (3) to press the sealing cover (4) so as to seal the waste water inlet (101) and the suction opening (102). A bottom end of the push rod (5) is connected to a side wheel component (6) of a floor cleaning machine and the push rod (5) can move up and down along the side wheel component (6).
