A hand vacuum cleaner has a handle provided at the rear end of the hand vacuum cleaner, the handle having a hand grip portion that extends upwardly and forwardly. An energy storage member is positioned above and overlying the hand grip portion, a suction motor and fan assembly that is positioned forward of the hand grip portion and a clean air outlet positioned rearward of the suction motor and fan assembly.

A surface cleaning apparatus has a cyclone chamber provided in an air flow path. The cyclone chamber has a screen assembly with an outlet section, a longitudinally spaced apart distal section and a longitudinally extending porous section. The outlet section includes a non-porous member extending longitudinally inwardly an outlet section length from an outlet end of the outlet section to a longitudinally inwardly positioned inlet end of the outlet section. The outlet end of the outlet section overlies a cyclone air outlet. The porous section extends longitudinally inwardly from an outlet end of the porous section that is located at the inlet end of the outlet section. The outlet section length is at least as long as the cyclone outlet port length.

A separating apparatus for a vacuum cleaner has a cyclonic separating chamber having a separator axis, a shroud disposed within the cyclonic separating chamber, an inner debris collection chamber for collecting debris separated by the cyclonic separating chamber, and an outer debris collection chamber for collecting debris separated by the cyclonic separating chamber. The inner debris collection chamber has a base and a debris outlet in fluid communication with the outer debris collection chamber. A shortest distance between the shroud and the base in a direction parallel to the separator axis is between 40% to 60% of a largest distance between the cyclonic separating chamber and the base in a direction parallel to the separator axis.

A dirt separator for a vacuum cleaner includes a first separation stage having a first dirt collection chamber; a second separation stage downstream of the first, the second separation stage having a second dirt collection chamber; a lid movable between closed and open positions to selectively block and unblock an emptying aperture provided in the first dirt collection chamber; and a latch mechanism. The first and second dirt collection chambers are movable relative to one another. The latch mechanism is configured to secure the dirt collection chambers in a first position, and to secure the lid in the closed position. The latch mechanism is configured to allow the first and second dirt collection chambers to move towards a second position, and to allow the lid to move towards the open position, when the latch mechanism is in the releasing configuration.

A separating apparatus for a vacuum cleaner has a first separating unit and a second separating unit movable between a first position and a second position with respect to the first separating unit. The separating apparatus has a collection chamber having an end wall movable between a closed position for collecting debris separated by the first separating unit, and an open position for removal of debris collected by the collection chamber. Movement of the second separating unit from the first position to the second position causes movement of the end wall from the closed position to the open position, and movement of the second separating unit from the second position to the first position causes movement of the end wall from the open position to the closed position.

A separating apparatus for a vacuum cleaner has a cyclonic separating chamber, an inner debris collection chamber for collecting debris separated by the cyclonic separating chamber, and an outer debris collection chamber for collecting debris separated by the cyclonic separating chamber. The inner debris collection chamber has a main body and a base mounted to the main body by a hinge. The hinge is formed of an elastomeric material.

A surface cleaning apparatus has a main body having a main body actuator operable between an open position and a closed position. An assembly removably mounted to the main body has an air treatment member having an openable door and an assembly door lock, the assembly door lock comprising an actuation portion operable between an open position and a closed position and lock portion operable between an engaged position in which the door is secured in a closed position and a disengaged position in which the door is openable. When the assembly is mounted to the main body, the main body actuator is operatively connected to the actuation portion of the assembly door lock whereby when the main body actuator is moved from the closed position to the open position, the actuation portion is moved.

A surface cleaning apparatus comprises an air treatment chamber, a pre-motor filter and a suction motor. The suction motor and the pre-motor filter are laterally spaced from the air treatment chamber. When the surface cleaning apparatus is positioned on a horizontal surface with the upper end of the air treatment chamber above the lower end of the air treatment chamber, the pre-motor filter is positioned at a higher elevation than the suction motor.

A wearable vacuum cleaner includes a harness configured to support the wearable vacuum cleaner on a user's back, a housing connected to the harness, a suction motor assembly disposed within the housing and operable to create a working airflow, and a collection bin configured to receive debris separated from the working airflow. The collection bin includes an opening adjacent a bottom portion of the collection bin and a lid moveably coupled to the collection bin to selectively cover the opening in a closed position and uncover the opening in an open position. The lid is movable to the open position to empty the contents of the collection bin through the opening while the collection bin remains attached to the housing.

A vacuum cleaner having a cyclone chamber comprising a cyclone air inlet, a cyclone air outlet, a cyclone axis of rotation, an axially extending cyclone chamber sidewall extending between first and second axially opposed ends. The cyclone chamber sidewall has a first sidewall portion that is axially moveably mounted with respect to a second sidewall portion of the cyclone chamber sidewall between a closed position in which the cyclone chamber is closed and an open position in which the cyclone chamber is opened.
