A vacuum cleaner tool having a brush head, a rotatable duct, and a hinge. The rotatable duct is configured to receive a hose or wand and rotates about the hinge relative to the brush head, between a use position and storage position. In a storage position, the rotatable duct extends generally parallel, or in-line with the brush head and, in a use position, the rotatable duct extends generally perpendicular to the brush head. The vacuum cleaner tool may removably attach to the vacuum cleaner via a release on one end of the brush head interacting with a fixed catch on the vacuum cleaner.

A vacuum cleaner is provided. The vacuum cleaner comprising a hand-held device, in which the hand-held device includes: a housing defining an air inlet, an air outlet and an air blowing port therein, the air blowing port being disposed adjacent to the air inlet; a dust cup disposed in the housing and connected with the air inlet; and an electric motor defining a motor chamber, wherein an airflow entering through the air inlet switchably flows out of one of the air outlet and the air blowing port by a switching mechanism after flowing through the dust cup and the electric motor.

There is provided a robot cleaner having an improved dust-collecting capability and an improved suction force and capable of being manufactured in a small size. The robot cleaner includes a main body comprising a fan motor and having a suction port provided in one side thereof; a plurality of cyclone units configured to separate foreign substances in air suctioned through the suction port; and a plurality of suction flow paths connecting the plurality of cyclone units and the suction port.

A suction nozzle for a vacuum cleaner includes a suction chamber; an outlet duct; an underside for engaging a surface to be cleaned; a main suction opening in the underside, which opens into the suction chamber; an auxiliary suction path which opens into the suction chamber; and a bleed path in fluid communication with the outlet duct. The suction nozzle further includes a valve mechanism arranged to open and close the auxiliary suction path and the bleed path, the valve mechanism being movable between a first configuration in which the auxiliary suction path is closed and the bleed path is open, a second configuration in which the auxiliary suction path is open and the bleed path is closed, and a third configuration in which both the auxiliary suction path and the bleed path are closed.

A vacuum appliance capable of picking up both wet and dry material is described, wherein the vacuum appliance includes an impeller configured to induce liquid into the vacuum appliance, a motor configured to turn the impeller, a restrictor assembly to prevent the liquid from being ingested into the motor, and a bypass vent assembly configured to allow sufficient air to reach the motor in order to keep the motor cool while the restrictor is preventing the liquid from being ingested into the motor. The vacuum appliance also includes a drum configured to retain the liquid and an impeller intake between the impeller and the drum. The restrictor may comprise a float configured to rise with a level of the liquid in the drum and prevent the liquid from entering the impeller intake. The bypass vent assembly may be configured to allow airflow to bypass the restrictor and/or the drum.

A cyclone filtration assembly unit is described. The unit is configured to mount in a vacuum cleaner, and includes a housing having a housing inlet for a dirty air stream and a housing outlet for a filtered air stream; one or more cyclone separators mounted in the housing, each of the one or more cyclone separators comprising one or more cyclone separator inlets, at least one dirt outlet, and at least one clean air outlet in fluid communication with the housing outlet; and one or more injector units configured to deliver an airstream of clean air from outside the housing and dirty air from inside the housing to the one or more cyclone separator inlets, the injector unit comprising: a diffuser duct having an inlet end in fluid communication with the housing inlet to introduce dirty air from the housing inlet to the cyclone separator inlet, and an injector tube configured to inject clean air into the diffuser duct adjacent the inlet end, the injector tube being in fluid communication with a housing aperture at an inlet end to introduce clean air from outside the housing to the diffuser duct.

An apparatus for a vacuum cleaner for compensating air pressure surges, where a first air flow is flowable in a first flow direction through the apparatus and a second air flow is flowable in a second flow direction through the apparatus, includes a main body having a first cross-sectional area of flow and a flow resistance element. A free end of the flow resistance element projects from the main body and produces a second cross-sectional area of flow. The first cross-sectional area of flow is larger than the second cross-sectional area of flow such that the second air flow flowable in the second flow direction is reduced.

A pet hair comb includes an installation shell body having an air duct, a grooming assembly, and a hair scraping assembly, wherein a relative movement between the hair scraping assembly and the grooming assembly allows the hair scraping assembly to scrape down the pet hair on the grooming assembly, wherein the pet hair comb has an air pressure adjusting port which is configured to be switched between an unblocked sate and a blocked state when the air duct is in a negative pressure state for sucking the pet hair, so as to adjust an air pressure in the air duct for facilitating the removal of the pet hair on the comb.

A blower includes an impeller, a motor that rotates the impeller, an electronic component that is disposed below a stator in an axial direction, and a circuit board that is disposed below a motor housing in the axial direction. The motor housing includes a motor housing inlet that has a cylindrical shape extending in the axial direction, that extends below a lower end of a blower housing in the axial direction and surrounds an outer side of the electronic component in a radial direction, that is formed below the lower end of the blower housing in the axial direction, and that allows an inner side and an outer side of the motor housing in the radial direction to communicate with each other.
