An all in the head surface cleaning apparatus includes a surface cleaning head and an upper portion that is moveably mounted to the surface cleaning head between a storage position and a floor cleaning position. The upper portion comprises a drive handle. A portable cleaning unit comprising an air treatment member and a suction motor is removably mounted in the surface cleaning head.

A cleaner includes: at least one cyclone configured to separate dust from suctioned air; a dust container configured to store the dust separated by the at least one cyclone; a dust compressor provided inside the dust container; and a lifter configured to move the dust compressor upward and downward.

A surface cleaning apparatus comprises a cyclone chamber having a cyclone axis of rotation and an openable portion wherein the openable portion is rotatably mounted about an opening axis that is parallel to the cyclone axis of rotation.

A hand vacuum cleaner comprises a cyclone unit comprising a first cyclonic stage and a second cyclonic stage. The first cyclonic stage has a first stage cyclone with a cyclone axis of rotation that extends between the front and rear ends of the cyclone. The cyclone axis of rotation extends through a central portion of the second cyclonic stage. The nozzle has a nozzle axis that extends through a central portion of the first stage cyclone between the front and rear ends of the cyclone.

A kit comprising a hand vacuum cleaner and a floor standing docking station for the hand vacuum cleaner. When the hand vacuum cleaner is docked with the floor standing docking station and the openable door of the hand vacuum cleaner is opened, dirt collected in the dirt collection region of the hand vacuum cleaner is transferrable to the dirt collection chamber of the floor standing docking station.

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 canister surface cleaning apparatus comprising an air treatment assembly. The air treatment assembly comprises an air treatment member and a dirt collection chamber exterior to the air treatment member. The air treatment assembly has first and second opposed ends and a sidewall that extends between the first and second ends. The sidewall has an openable door whereby the dirt collection chamber is opened when the door is opened, and the air treatment member is removably mounted in the first end of the air treatment assembly.

A dust separation device includes: an air inlet, a dust collection chamber to collect dust in air flowing in from an air inlet, a rotating body rotatable inside the dust collection chamber and including a blocking member formed to block dust from the air flowing in from the air inlet, a motor to rotate the rotating body, a fixing body arranged to be spaced apart from the rotating body and supporting the motor, and a sealing member configured to seal at least a portion of a gap portion formed between the rotating body and the fixing body to prevent dust from entering the gap portion, the sealing member including a brush in contact with at least one of the rotating body and the fixing body.

The cleaner includes a suction inlet configured to guide air and dusts, a main body including a first cyclone unit configured to separate the air and the dusts, which are suctioned through the suction inlet, from each other, and a dust separation module separably connected to the main body and including a second cyclone unit configured to separate the dusts from the air discharged from the first cyclone unit.

A hand vacuum cleaner comprises an air flow path from a dirty air inlet to a clean air outlet; a main body comprising a bottom, a handle, a suction motor and fan assembly and at least one battery, the suction motor and fan assembly having a suction motor axis of rotation; and, an air treatment member provided on a front end of the main body, wherein the at least one battery and the suction motor and fan assembly are positioned in the air flow path downstream from the air treatment member.
