A hand vacuum cleaner comprises a main body has a driving handle and houses a suction motor and fan assembly, the suction motor and fan assembly having a suction motor axis of rotation wherein the driving handle has a hand grip portion that extends upwardly and forwardly when the hand vacuum cleaner is oriented with the upper end above the lower end. An air treatment member has a dirt collection region having an openable door provided on a front end of the air treatment member.

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 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 positionable in the volume. A pistol grip handle assembly is provided on a lower portion of the main body. The handle assembly is positioned rearward of the volume and the air treatment member assembly is removable downwardly.

A vacuum cleaner has a portable cleaning unit that is removably mounted to the surface cleaning head. The vacuum cleaner is operable in a floor cleaning configuration in which the portable cleaning unit is mounted to the surface cleaning head and is part of the air flow path through the vacuum cleaner. The portable cleaning unit is also useable in a portable cleaning configuration in which the portable cleaning unit is removed from the surface cleaning head and the suction motor is powered by an energy storage member.

A cleaner includes: a suction motor that generates suction force; a dust separation unit that is disposed behind the suction motor and separates dust from air sucked by the suction force of the suction motor; a dust container that stores dust separated by the dust separation unit; a handle disposed behind the dust separation unit; a battery housing disposed under the handle; and a battery that is detachably coupled to the battery housing and is separable downward from the battery housing.

A cleaner includes: a main body that has an opening; a suction motor that is disposed in the main body and generates suction force; and a filter unit that includes an exhaust filter for filtering air discharged from the suction motor, the filter unit being inserted into the main body through the opening and being separated from the main body, wherein when the filter unit is combined with the main body, a portion of the filter unit protrudes out of the main body, and a portion of the exhaust filter is positioned inside the main body and the other portion of the exhaust filter is positioned outside the main body.

A vacuum cleaner including: a suctioning unit; a main body including a cyclone part for separating dust from suctioned air and a dust container for storing the separated dust, and a body cover for opening and closing the lower side of the body; a filter unit, disposed in the body, for filtering air separated from the dust; an actuating unit capable of moving in the body between the outside of the filter unit and the inner circumference surface of the body; an operating unit disposed outside the body which operates in order to move the actuating unit; a transmission unit penetrating the body and connecting the actuating unit with the operating unit; and an elastic member disposed outside the body which elastically supports the operating unit.

A vacuum cleaner nozzle having a rotatable member for picking up particles from a surface to be cleaned, and an external cleaning apparatus for removing articles entangled to the rotatable member. The nozzle includes a support surface provided on a radially projecting member of the rotatable member, and a cleaning member provided on the external cleaning apparatus. During rotation of the rotatable member, the cleaning member co-operates with the support surface to remove entangled articles from the rotatable member.

A hand vacuum cleaner has a cleaner body and a post-motor filter is positioned in the air flow passage downstream from and aligned with the suction motor and, the post-motor filter and the cleaner body are separable.

A surface cleaning apparatus comprises a hand vacuum cleaner, a surface cleaning head and a rigid air flow conduit extending between the surface cleaning head and the hand vacuum cleaner. The hand vacuum cleaner comprises a main body and a removably mounted air treatment member. The air treatment member has an air inlet and the outlet end of the rigid air flow conduit is removably connectable in air flow communication with the air inlet.

A cleaner includes: a main body that has an opening; a suction motor that is disposed in the main body and generates suction force; and a filter unit that includes an exhaust filter for filtering air discharged from the suction motor, the filter unit being inserted into the main body through the opening and being separated from the main body, wherein when the filter unit is combined with the main body, a portion of the filter unit protrudes out of the main body, and a portion of the exhaust filter is positioned inside the main body and the other portion of the exhaust filter is positioned outside the main body.
