A buckle mechanism of a dust collecting barrel of a two-stage dust collector is provided. The buckle mechanism is disposed on the two-stage dust collector, and includes a first retaining seat and a second retaining seat corresponding to one side of the dust collector, and a support unit is disposed on a barrel cover. The first retaining seat is pivotally connected with a linking unit. One end of the linking unit is connected to the support unit. The second retaining seat is pivotally connected with a control unit. The linking unit is driven to actuate through two connecting members. The control unit drives the linking unit to actuate. By the lever principle, the linking unit drives the barrel cover to move up and down so as to assemble and disassemble the dust collecting barrel quickly and conveniently.

An apparatus comprises a body, a first tank, a second tank, a vacuum motor, a fluid pump, and a controller. The body comprises a handle and an accessory connection receptacle comprising a fluid output and an electrical contact. The first tank comprises a first vessel configured to accommodate a fluid. The second tank comprises a second vessel separated from the first vessel. The controller is configured to activate the fluid pump to cause fluid contained in the first tank to be supplied to the fluid output, and to activate the vacuum motor to draw one or more of air, debris, a liquid or a portion of the fluid into the second tank. The accessory connection receptacle is configured to accommodate a correspondingly shaped accessory connector configured to mate with the accessory connection receptacle and be communicatively coupled with the fluid output and with the electrical contact.

A latch mechanism has two pieces that mount in an opening on the lid of a conventional vacuum cleaner. A stationary part is held in place by a hooked end that fits over a pivot edge on the lid, and by a retaining surface that engages a retaining edge on the lid. The other part is a pivoting latch that hooks onto the same pivot edge. In a latched position, an engagement surface on a deflectable arm fits over a latching surface on the stationary part, holding a moving part in position with a latching part beneath a bead on the tank. A tab surface can be used to force the deflectable arm to deflect over the latching part and simultaneously move the latching part clear of the bead.

A vacuum cleaner and carrier assembly includes a vacuum cleaner and a carrier. The vacuum cleaner includes a housing having a suction inlet and an air outlet, an airflow passage that extends from the air inlet to the air outlet, and a suction source disposed within the housing and operable to generate a suction airflow that travels through the air inlet and through the air outlet. The vacuum cleaner also includes a battery that supplies power to the suction source to generate the suction airflow. The carrier includes a main body in which at least a portion of the housing is received and a battery receiving portion configured to receive the battery therein when the battery supplies power to the suction source.

A surface cleaning device including a surface-contacting assembly having a suction opening; a body; a suction source in fluid communication with the suction opening for sucking a fluid mixture of liquid and air from a surface; a rotation assembly mounted on the body for rotation relative to the body, the rotation assembly being rotationally fixed relative to the surface-contacting assembly, a separation chamber in which liquid is separated from the fluid mixture, the separation chamber providing a suction inlet in fluid communication with the suction opening, a suction outlet in fluid communication with the suction source, and a drainage outlet for connection to a receptacle for receiving liquid separated from the fluid mixture; and a receptacle for receiving liquid separated from the fluid mixture via the drainage outlet.

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 surface cleaner that includes an accessory body removably coupled to a base. A nozzle has a first nozzle portion having a first nozzle passageway attached to the base and a second nozzle portion having a second nozzle passageway attached to the accessory body and removable with the accessory body. The first nozzle portion and second nozzle portion are releasably coupled connecting the first and second nozzle passageways along an airpath in fluid communication with a collection container when the accessory body is coupled to the base. The first nozzle passageway forms a suction inlet when the accessory body is coupled to the base and the second nozzle passageway forms the suction inlet in communication with the collection container and the suction source when the accessory body is uncoupled from the base.

A handheld extraction cleaner includes a fluid delivery system and a recovery system including a suction nozzle, a recovery tank, and a suction source. The recovery tank has an auto-close feature that automatically seals an outlet of the tank when the recovery tank is mounted to a tank receiver of the extraction cleaner.

An upright surface cleaning apparatus comprises a surface cleaning head and an upright section. The surface cleaning head has rear wheels having a diameter and a central longitudinal axis extending between the front and rear ends. The upright section is movably mounted to the surface cleaning head between a generally upright position and a rearwardly inclined in use position. The upright section has an air treatment member assembly comprising an air treatment member, a dirt collection region wherein at least a portion of the dirt collection region is exterior to and laterally spaced with respect to the air treatment member and a housing having a suction motor therein. The diameter of the rear wheels is greater than a depth of the portion of the dirt collection region in a direction of the central longitudinal axis.

A self-moving cleaning robot comprises a body and a water tank. The water tank includes a tank body having an air duct and a fan accommodation cavity extending from the bottom of the tank body toward the top of the tank body. An opening end of the fan accommodation cavity faces downwards of the tank body. An air inlet is provided on a side wall of the tank body, and an air outlet is provided at the top of the fan accommodation cavity. The air duct is formed in an inner cavity of the tank body, comprising a second channel formed by side walls of the fan accommodation cavity and corresponding portions of side walls of the tank body, and a first channel located in the inner cavity of the tank body between the air inlet and the fan accommodation cavity.
