A hand vacuum cleaner has a cyclonic unit comprising a first cyclonic stage and a second cyclonic stage. The front end of the first cyclonic stage has a front door that is moveable between a closed position and an open position. A latch secures the front door in the closed position. The front door has a first portion which is rotatably mounted to a front end of a cyclone unit sidewall and a second portion angularly spaced around the front door from the first portion, the second portion having the latch.

A surface cleaning apparatus comprises a hand vacuum cleaner, a rigid air flow conduit and a surface cleaning head. The hand vacuum cleaner has a body, which houses a suction motor, and a cyclone unit provided on a front end of the body. The cyclone unit has a cyclone with a cyclone axis of rotation that extends between the front and rear ends of the first stage cyclone. Air enters the cyclone unit through a cyclone unit air inlet that is centrally positioned on a front end wall of the cyclone. A front electrical connector is positioned adjacent the cyclone unit air inlet. When the hand vacuum cleaner is mounted to the rigid air flow conduit, the rigid air flow conduit is concurrently connected in air flow communication with the cyclone unit air inlet and the outlet end electrical connector is electrically connected to the front electrical connector.

A hand vacuum cleaner comprises a body which houses a suction motor. An end of a handle is provided on a sidewall of the body and extends outwardly therefrom. An air treatment member comprises a chamber, which has an openable door and which forms a front face of the hand vacuum cleaner. An openable door lock comprises an axially extending member having a front end and a rear end and, when the door is in a closed portion, the front end secures the openable door in the closed position and the door release actuator is rotationally mounted and, in use, the door release actuator is rotated to drive the axially extending member whereby the door is unlocked.

A handheld vacuum cleaner includes a frame, and a dust barrel and a locking portion mounted on the frame, wherein a front end of the dust barrel and the locking portion are movable relative to each other and are arranged opposite to each other; the dust barrel has a rotatable front cover at a front side thereof; and when the locking portion and the dust barrel move with respect to each other, the front cover is automatically rotatable to open, or close on the front side of the dust barrel due to limit by the locking portion.

A cleaner includes: a main body that has an opening; a suction motor that is disposed in the main body and generates suction force; and a filter unit that includes an exhaust filter for filtering air discharged from the suction motor, the filter unit being inserted into the main body through the opening and being separated from the main body, wherein when the filter unit is combined with the main body, a portion of the filter unit protrudes out of the main body, and a portion of the exhaust filter is positioned inside the main body and the other portion of the exhaust filter is positioned outside the main body.

In general, the present disclosure is directed to a hand-held surface cleaning device that includes a relatively compact form-factor to allow users to store the same in a nearby location (e.g., in a drawer, in an associated charging dock, on a table top) for easy access to perform relatively small cleaning tasks that would otherwise require retrieving a full-size vacuum from storage. A hand-held surface cleaning device consistent with aspects of the present disclosure includes a body (or body portion) with a motor, power source and dust cup disposed therein. The body portion also functions as a handgrip to allow the hand-held surface cleaning device to be operated by one hand, for example.

A dust-collecting box includes a dust-collecting box body and a filter screen. The dust-collecting box body defines a dust inlet, a dust receiving cavity and an exhaust passage which are communicated in sequence, an air inlet end of the exhaust passage is in communication with the dust receiving cavity, and an air outlet end of the exhaust passage is in pneumatic communication with a fan assembly. The filter screen is arranged between the air inlet end and the air outlet end, the filter screen filters an airflow entering the exhaust passage from the dust receiving cavity, an exhaust direction of the air outlet end is defined as a preset reference direction, and the filter screen is arranged obliquely relative to the preset reference direction.

A wet-dry vacuum cleaner including a collecting bin and a power head removably coupled to the collecting bin. The power head includes a housing configured to support the power head on the collecting bin, an exhaust outlet, and a cyclonic separator positioned within the housing. The cyclonic separator includes a dirty air inlet, a chamber, and a clean air outlet. The power head further includes a suction motor assembly operable to create a working airflow path from the dirty air inlet to the exhaust outlet, and a filter disposed within a filter housing hanging downwardly from the suction motor assembly. The filter is positioned within the working airflow path adjacent the clean air outlet of the cyclonic separator.

A surface cleaning apparatus comprises a hand vacuum cleaner, a surface cleaning head and a rigid air flow conduit removably mountable between the surface cleaning head air outlet and the dirty air inlet of the hand vacuum cleaner. The hand vacuum cleaner comprises a main body and a cyclone unit. The main body has a suction motor axis of rotation and an axially extending sidewall wherein an end of a pistol grip handle is mounted to the sidewall. The dirty air inlet of the hand vacuum cleaner is removably drivingly mounted to a downstream end of the rigid air flow conduit. When the hand vacuum cleaner is positioned with the front end of the hand vacuum cleaner in front of the rear end of the hand vacuum cleaner, the cyclone axis of rotation is generally horizontal.

A robot cleaner comprising: a cleaner body including a controller, the cleaner body having a dust container accommodation part formed therein; a wheel unit mounted in the cleaner body, the wheel unit of which driving is controlled by the controller; and a dust container detachably coupled to the dust container accommodation part, wherein a first opening and a second opening are disposed at the same height in an inner wall of the dust container accommodation part, wherein the dust container includes: an entrance and an exit, disposed side by side along the circumference of the dust container, the entrance and the exit, respectively communicating with the first opening and the second opening when the dust container is accommodated in the dust container accommodation part; and a flow separating part extending downwardly inclined along the inner circumference of the dust container.
