A hand vacuum cleaner has a cyclone unit having a cyclone with a horizontal cyclone axis of rotation. The front end of the cyclone unit comprises a front door that is moveable between a closed position and an open position. A lock secures the front door in the closed position, the lock comprising an actuator, wherein the actuator is spaced towards the rear end of the cyclone.

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.

The present invention relates to a cleaner including a dust bin having an inlet port formed at one side thereof, a discharge port formed at the other side thereof, and a cyclone part provided therein and configured to generate a cyclone flow, and a suction part configured to communicate with the inlet port and elongated in one direction, in which the cyclone part includes an axis of a cyclone flow, which is perpendicular to a longitudinal axis of the suction part and parallel to the ground surface, such that the cleaner may clean a lower region such as a gap below a sofa or furniture without affecting a height of a main body of the cleaner even though a length of the dust bin increases.

A dust collecting device and an electric vacuum cleaner with it are provided. The dust collecting device comprises a main body with an opening, a first dust collector with a first dust collecting brush for collecting dust, and a second dust collector with a second dust collecting brush for collecting dust; the first dust collector and the second dust collector are rotatably held in parallel inside the main body; when the first dust collecting brush is at the opening, the first dust collecting brush is inclined toward the second dust collector; when the second dust collecting brush is at the opening, the second dust collecting brush is inclined toward the first dust collector. The dust collecting device can collect dust even when the power of the electric vacuum cleaner is turned off and can be used at any time without worrying about noise.

A vacuum cleaner includes a foot assembly having a suction inlet thereon, a suction source in fluid communication with the suction inlet to produce a working airflow there through, and a dirt container in fluid communication with the suction inlet and suction source. The foot assembly further includes a body defined by a central portion and a pair of extension arms, a rotatable agitator on each extension arm, and a drive assembly configured to counter-rotate the agitators. The counter-rotating agitators are operable to cooperate with the suction source to direct dust and debris towards the suction inlet.

A hand vacuum has a cyclone assembly which comprises a cyclone chamber and a dirt collection chamber exterior to the cyclone chamber. The cyclone assembly comprises a stationary portion and an openable portion. The openable portion is rotatably mounted by a rotatable mount between a closed position in which the cyclone chamber and the dirt collection chamber are closed and an open position in which the cyclone chamber and the dirt collection chamber are open. The rotatable mount is located at a rearward end of the openable portion.

A cleaner includes: a main body that forms an external shape; a dust container that is separably combined with the main body and stores dust separated from air; a dust container cover that is configured to open and close the dust container; a handle unit that is disposed behind the dust container; and an operating member that is configured to provide operation force to the dust container cover by moving in a first direction and to release a holding mechanism for preventing separation of the dust container from the main body by moving in a second direction opposite to the first direction.

A cleaner includes a suction unit, a main body including a cyclone unit for separating dust from air suctioned through the suction unit, and a dust container that stores dust separated in the cyclone unit below the cyclone unit. A filter unit is disposed inside the cyclone unit for filtering the air, and a movable unit disposed inside the cyclone unit includes a cleaning part for cleaning the outer circumference of the filter unit. An operation unit disposed outside the main body moves the movable unit and the cleaning part to remove dust from the outer surface of the filter unit.
