A cleaner capable of separating a dust separator from a main body and separating a dust container from the dust separator by using a button. The cleaner includes: a main body; a dust separator detachably coupled to the main body configured to separate dust contained in air; a dust container detachably coupled to the dust separator; and a button configured to separate the dust separator from the main body and separate the dust container from the dust separator, when the dust separator is separated from the main body.

A docking station for a robotic surface cleaning apparatus is provide. The docking station has a plurality of cyclones comprising an upper cyclone and a lower cyclone. The cyclones are arranged such that the dirt outlet of the upper cyclone is not obstructed by the dirt outlet of the lower cyclone.

An air treatment apparatus has a momentum separator positioned in an air flow path. The momentum separator has an upper wall, a lower wall, a sidewall extending between the upper and lower walls and a momentum separator air inlet. A momentum separator air inlet is provided in an inlet portion of the sidewall. The momentum separator air inlet faces an opposed portion of the sidewall that is opposed to the inlet portion of the sidewall and the inlet portion of the sidewall comprises a side screen.

A dust suction system comprises a cyclonic dust filter component, a dust collection bucket and a load bearing frame. The dust collection bucket comprises an assembly rib, the load bearing frame comprises a frame and a support plate disposed on the frame, and the support plate comprises a through hole disposed corresponding to a dust exhausting port, and at least two assembly jaws located at two opposite sides of the through hole. Each of the assembly jaws comprises a connecting section, an extending section connecting the connecting section, and a limiting section connecting the extending section. The limiting section comprises a limiting protrusion disposed towards a direction of the through hole. When the two assembly jaws are not forced, movement of the assembly rib is restricted by the limiting section, so that the dust collection bucket is fixed on the frame.

Disclosed is a cyclone dust collector in which usability is improved. A vacuum cleaner comprising a cyclone dust collector, wherein the cyclone dust collector includes, a case configured to swirl suctioned air to separate dust from the suctioned air and accommodate the separated dust, a grill assembly separably installed in the case, and a cleaning portion included in the case and configured to remove dust adhered to a surface of the grill assembly when the grill assembly is separated from the case.

A hand vacuum cleaner with a finger grip area that is provided between a forward side of the handle and a rear side of the main body, and wherein the suction motor is positioned between the cyclone and the finger grip area and an axis that extends between the front of the cyclone and the handle extends through the suction motor.

A surface cleaning apparatus comprises an air treatment member having an air treatment chamber. A moveable member is positioned in the air treatment chamber. A handle is drivingly connected to the moveable member by a driving linkage wherein part of the driving linkage extends through a slot in the sidewall of the air treatment member, whereby the moveable member is longitudinally translatable through at least a portion of the chamber.

Provided is a cleaning device including a vacuum cleaner including a dust collector into which dirt and dust is collected, a docking station connected to the dust collector and having a long axis extending in a first direction, and the docking station includes a docking part coupled to the dust collector to remove dirt and dust collected in the dust collector, a sucking device sucking up the dirt and dust and inside air in the dust collector docked with the docking part through the docking part, and a circulation duct arranged for the air sucked up by the sucking device to be circulated to the docking part.

A hand vacuum cleaner has a cyclonic stage comprising an openable front wall provided at the front end of the cyclonic stage. A pre-motor filter is positioned in the air flow passage downstream from the cyclone air outlet and rearward of the cyclone sidewall. The pre-motor filter has a diameter in a direction transverse to the cyclone axis that is larger than a diameter of the cyclone air outlet in the direction transverse to the cyclone axis. The pre-motor filter has an outer perimeter defining a volume and the cyclone axis and the motor axis each extend through a centre of the volume. The cyclone axis is generally parallel to the motor axis. When the openable front wall is opened, the front end of the cyclone stage is opened and has an opening, the opening has a diameter in the direction transverse to the cyclone axis, and the rear end of the cyclonic stage has a diameter that is generally equal to the diameter of the opening. The cyclonic stage is removable from a cleaner body which houses the suction motor with the openable front wall in a closed position. When the first cyclonic stage is removed, the pre-motor filter is accessible for removal.

A cleaner may include a cleaner main body or a main body; a dust container which is accommodated in the cleaner main body; a dust container cover or a cover which covers an upper portion of the dust container; a handle which is coupled to an upper end of the dust container cover; a sensing unit or module which detects information around the cleaner main body; and a rotation module or assembly which rotates the sensing unit relatively with respect to the dust container cover.
