A suction apparatus includes a housing, at least one cyclone chamber, a collection container configured to as to be releasably connectable to the housing, and having a filter element. The suction apparatus further includes at least one positioning device within the cyclone chamber and configured for positioning at least one collection element within the cyclone chamber.

A canister surface cleaning apparatus comprising a canister body having a recess. The recess comprises a wall and sidewalls that extend away from the wall to define a volume. An air treatment assembly is removably mountable to the canister body. When the air treatment assembly is mounted to the canister body and the canister body is positioned with on the floor, the wall extends generally vertically and one of the sides of the air treatment assembly faces the wall and is positioned in the recess.

A surface cleaning apparatus has a cyclone bin assembly having a cyclone chamber. The cyclone chamber with a physical filtration member defining the cyclone air outlet. The physical filtration member has an outer wall wherein at least a portion of the outer wall is porous and a plurality of ribs is spaced around the outer wall. The ribs have a radial inner side that has an inner width in the direction of rotation and a radial outer side that has an outer width in the direction of rotation that is narrower than the inner width.

A hand vacuum cleaner has an air treatment member positioned in an air flow path through the hand vacuum cleaner. The air treatment member comprises an air treatment chamber and a dirt collection chamber exterior to the air treatment chamber. The air treatment member comprises a stationary portion and an openable portion, the openable portion comprises a portion of a sidewall of the air treatment chamber and the openable portion is moveably mounted by a mount between a closed position in which the air treatment chamber and the dirt collection chamber are closed and an open position in which the air treatment chamber and the dirt collection chamber are open. When the inlet conduit extends generally horizontally, the dirt collection chamber underlies the air treatment chamber.

A vacuum cleaner comprising a suction source operable to generate an airflow, a first stage cyclonic separator configured to separate debris from the airflow, the airflow rotatable about a first stage separator axis in the first stage separator to separate the debris from the airflow, a second stage cyclonic separator downstream from the first stage cyclonic separator, the second stage cyclonic separator configured to separate debris from the airflow, a first stage collector configured to receive debris from the first stage cyclonic separator, and a second stage collector configured to receive debris from the second stage cyclonic separator, the second stage collector being within the first stage collector, the second stage collector having a cross section taken normal to the first stage separator axis that is polygonal.

Provided is a cleaner. The cleaner includes a housing provided with a dust container at a lower side thereof having a suction opening, a filter part configured to filter dust from air suctioned through the suction opening, the filter being spaced apart from an inner circumferential surface of the housing, a movable part configured to be elevated between a first position and a second position in a space between the outside of the filter part and the inner circumferential surface of the housing, a manipulation part of which at least a portion is exposed to outside of the housing, the manipulation part being elevated by user's manipulation, and a transfer unit of which at least a portion is accommodated in the housing, the transfer unit being configured to connect the manipulation part to the movable part. The dust container has an elevation groove, which is recessed outward from an inner surface of the dust container, in a vertical direction.

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 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 cyclone axis of rotation intersects the pistol grip handle. The cyclone axis of rotation is generally horizontal.

A bucket lid for a cyclone dust collector is configured to fit onto a standard pail or bucket, with a circumferential rim forming an outer edge of the lid, a central mounting disk onto which the cyclone is mounted, and a series of baffles extending circumferentially around the lid between the mounting disk and the rim. These baffles extend downward into the bucket to interfere with swirl in the bucket from dust discharged from the cyclone. The baffles may be radial ribs alternating with ramped coffers. The lid may be formed of anti-static polypropylene.

A hand vacuum includes a nozzle portion at a front end of the hand vacuum having a dirty air inlet. An air flow passage extends from the dirty air inlet to a clean air outlet in a main body rearward of the nozzle portion. The main body houses a suction motor in the air flow passage. First and second laterally spaced apart opposed arm members extend generally axially between the nozzle portion and the main body, and a volume is positioned between the nozzle portion, the main body and the opposed arm members. An air treatment member assembly comprising an air treatment member is removably downwardly from a position within the volume.
