A surface cleaning apparatus having an upright section moveable relative to a surface cleaning head between a storage position and a rearwardly reclined floor cleaning position. The upright section comprising a removable hand vacuum cleaner. The hand vacuum cleaner is operable in a first mode of operation in which the surface cleaning apparatus is operated to clean a floor, the inlet of the hand vacuum cleaner is in flow communication with the surface cleaning head air outlet and the air treatment member of the hand vacuum cleaner is operable to treat air drawn in through the dirty air inlet of the surface cleaning head. The hand vacuum cleaner is also operable in a second mode of operation in which the hand vacuum cleaner is operable to directly clean a floor or the air inlet of the hand vacuum cleaner is directly connected to the downstream end of an accessory tool.

A vacuum cleaner is described herein that uses an elongated design that provides the various vacuum components along nearly an entire length of the vacuum cleaner and in-line with one another. According to some embodiments, at least one waste receptacle, a filter structure, and a motor are each axially aligned with a longitudinal central axis of a body of the vacuum cleaner. An air suction inlet may also be arranged at a distal end of the body and axially aligned with the longitudinal central axis. In some examples, the body maintains a substantially constant diameter along its entire length.

A separator unit for a suction apparatus contains a collection container with a collection area for receiving particles of dirt from a suction airflow. The collection container runs along a longitudinal axis from a first end side, which during the operation of the suction apparatus faces the blower of the suction apparatus, up to a second end side on which the cover of the collection container is arranged. The separator unit contains a filter module arranged in the collection container and is configured to filter particles of dirt out of the suction airflow. The collection area is adjacent to the surface of the filter module and the filter module is configured so as on the first end side of the collection container to be removed from the collection container or to be inserted into the collection container.

A hand vacuum cleaner has an air treatment chamber which has an axis extending between the front and rear ends of the air treatment chamber. An openable door is rotatably moveable to an open position in which an opening is provided and dirt collected by the hand vacuum cleaner is emptyable through the opening. A rotational mount is provided at a first end of the openable door and an opposed second end is moveable to enable the hand vacuum cleaner to be emptied through the opening, wherein in the closed position, the opposed second end is located at the front end of the hand vacuum cleaner. A latch releasable secures the door in the closed position. An axial projection of the dirty air inlet extends centrally through the air treatment chamber and the axis on the inlet conduit extends in a common direction with the air treatment chamber axis.

A combination of a hand vacuum cleaner and a floor standing unit. The hand vacuum cleaner is positionable in a docked configuration, in which the hand vacuum cleaner is docked with the floor standing unit and in which the floor standing unit is positioned on a floor. In the docked configuration with an openable door of an air treatment assembly of the hand vacuum cleaner opened, dirt collected in the dirt collection region of the air treatment assembly is transferrable to a dirt collection chamber of the floor standing unit. Further, in the docked configuration, a horizontal plane, which is generally transverse to the main body axis of the hand vacuum cleaner, extends through a rear wall of the dock and the air treatment chamber.

A hand vacuum cleaner has a cyclone having a longitudinally extending sidewall, which extends from a cyclone rear end to a cyclone front end. The front end of the sidewall defining an opening that is closeable by an openable door. The opening having a cross-sectional area comparable to a cross-sectional area of the door. The opening extends in a direction that is inclined relative to the longitudinal direction of the sidewall. The openable door has a rotatably mounted end and an opposed securable end that is securable to the cyclone by a lock. The opposed securable end is rotatable to an open position in which the opposed securable end is positioned forward of the opening.

A hand vacuum cleaner has a cyclone having a cyclone axis of rotation that extends between the front and rear ends of the cyclone. A main body houses a suction motor. The suction motor is positioned at a lower end of the main body and forward of a battery pack provided at a lower end of a pistol grip handle.

A hand vacuum cleaner has a cyclonic stage comprising a cyclonic stage front end, a cyclonic stage rear end, a cyclonic stage sidewall, a cyclone, the cyclonic stage front end having an openable door, the cyclone comprising a cyclone front end, a cyclone rear end, a cyclone air inlet, a cyclone air outlet and a cyclone axis of rotation which intersects the cyclone front end and the cyclone rear end, the cyclone air outlet comprising an assembly which includes a filter screen. The assembly is removeable through the cyclonic stage front end when the openable door is in an open position.

A surface cleaner has a wiper moveable between a first position and a second position relative to porous section of an air treatment chamber air outlet passage. In a surface cleaning mode in which the surface cleaner is operable to clean a surface, the wiper is in the first position and is positioned towards the second end of the air treatment chamber. In an air treatment chamber cleaning mode, the wiper is in the second position and is further away from the second end of the air treat chamber than in the first position. A handle is operable to move the wiper between the first position and the second position to manually clean at least some of the porous section wherein, as the wiper cleans the porous section, the wiper is positioned in the air treatment chamber between the sidewall of the air treatment chamber and the porous section.

A surface cleaner has an air flow path extending from a dirty air inlet to a clean air outlet with a suction motor positioned in the air flow path, a cyclone chamber positioned in the air flow path, and a dirt collection chamber. The cyclone chamber has a first end, an opposed second end, a cyclone axis of rotation that intersects each of the first and second ends, a cyclone sidewall extending between the first and second ends, a cyclone air inlet provided at the first end, a cyclone air outlet and a dirt outlet. The second end of the cyclone chamber has a ramped surface that curves around the cyclone chamber from a proximal end to a distal end. The proximal end is closer to the first end of the cyclone chamber than the distal end. The dirt outlet is provided at the distal end of the ramped surface.
