A surface cleaning apparatus has a dirty air inlet and an air treatment member. The air treatment member includes a dirt collection region having an openable door. When an accessory is connected to the dirty air inlet, the openable door is inhibited from opening.

A handheld vacuum cleaner (10, 1010) includes a main body (22, 1022) with a handle (98, 1098) and a bottom surface (102) upon which the vacuum cleaner is configured to be positioned on a horizontal surface (106), a motor assembly (114, 1114) positioned in the main body, and a cyclonic separator assembly (26) removably coupled to the main body. The cyclonic separator assembly includes an inlet nozzle (42) having a dirty air inlet (14, 1014) positioned at a front (50, 1050) of the handheld vacuum cleaner when the cyclonic separator assembly is coupled to the main body, a cyclonic chamber (30, 1030) in fluid communication with the dirty air inlet, and a dirt collection region (38) configured to receive debris separated in the cyclonic chamber. The handheld vacuum cleaner further includes a release actuator (438) configured to release the cyclonic separator assembly from the main body when actuated by a user. The release actuator is accessible from a bottom (94) of the main body.

A cyclonic air treatment member comprises a cyclone and a dirt collection chamber external to the cyclone chamber. The dirt collection chamber has first and second discrete dirt outlet regions, each dirt outlet region extending around a portion of the perimeter of the cyclone chamber. The second dirt outlet region is positioned proximate the cyclone second end, and the first dirt outlet region is positioned toward the cyclone first end relative to the second dirt outlet region.

A handheld vacuum cleaner includes a dust cup assembly, a suction nozzle assembly and a handle assembly. The dust cup assembly includes a cup casing, an airflow generation device and a cyclone separation device, both of which are arranged in the cup casing, the airflow generation device being arranged above the cyclone separation device and positioned on a downstream side of the cyclone separation device, and an air vent being formed in a top of the cup casing. The suction nozzle assembly is mounted to the cup casing and defines a suction channel. The handle assembly is mounted to the cup casing and used to be held. With the structure, a blowing direction of the air vent is not towards a surface to be cleaned, so as to prevent the wind from the air vent blows away dust on the surface to be cleaned and hence ensure a cleaning effect.

A hand vacuum cleaner having an air treatment member positioned in the air flow passage upstream from a suction motor and comprising a dirt chamber having an openable door, wherein an openable lock securing the door in a closed position is provided. A hand vacuum cleaner having a cyclonic stage and a suction motor, wherein the cyclone unit is mounted to a motor housing wherein a projection of the motor axis extends through the cyclonic stage is also provided.

A surface cleaning apparatus comprises a hand vacuum cleaner, a surface cleaning head and a rigid air flow conduit. The hand vacuum cleaner has a main body housing dual cyclonic cleaning stages and a suction motor and fan assembly.

A cyclone pre-separator for positioning on a particle collecting container, the cyclone pre-separator including a box-shaped housing and a cyclone unit arranged in the housing, the cyclone unit including an air inlet, an air outlet, and a particle outlet arranged on a underside of the cyclone pre-separator, where the housing has an air inlet hose port connected to the air inlet and an air outlet hose port connected to the air outlet, and has lower housing couplers, adapted to provide a releasable, vertically tension-proof coupling to the particle collecting container, when the cyclone pre-separator is positioned on the particle collecting container.

A vacuum cleaner includes a housing having a dust inlet and a first latch. The first latch is moveable between a locked position and an unlocked position. The vacuum cleaner also includes a second latch moveable between a locked position and an unlocked position, and a spring pressing the second latch to the locked position. The vacuum cleaner also includes a dust bin securable on the housing with the first latch and the second latch. When the dust bin is being installed onto the housing, the second latch is moved from the locked position to the unlocked position until the spring presses the second latch back to the locked position. The dust bin is secured on the housing when the dust bin is installed on the housing, the first latch is in the locked position, and the second latch is in the locked position. The dust bin is removable from the housing when the dust bin is installed on the housing, the first latch is in the unlocked position, and the second latch is in the locked position.

A surface cleaning apparatus has a first air flow path extending from a dirty air inlet to a clean air outlet with a suction motor and a cyclone positioned in the first air flow path. The cyclone has a cyclone chamber, a first airflow passage, and a second airflow passage. The first airflow passage defines a first tangential air inlet to the cyclone chamber and the second airflow passage defines a second tangential air inlet to the cyclone chamber. The airflow path includes a common airflow passage upstream of the first and second airflow passages and an axis of the common airflow passage intersects the cyclone chamber. At least a portion of the first tangential air inlet is positioned upstream from a location at which the common airflow passage axis intersects the cyclone chamber.

A surface cleaning apparatus has a first air flow path extending from a dirty air inlet to a clean air outlet with a suction motor and a cyclone positioned in the first air flow path. The cyclone has a cyclone chamber, a first airflow passage, and a second airflow passage. The first airflow passage and second airflow passage are isolated from each other. The first airflow passage defines a first tangential air inlet to the cyclone chamber and the second airflow passage defines a second tangential air inlet to the cyclone chamber. The second tangential air inlet is positioned around the perimeter of the cyclone chamber sidewall downstream from the first tangential air inlet in the direction of rotation of air in the cyclone chamber.
