A hand vacuum cleaner may have an air treatment member and a pre-motor filter downstream from the air treatment member. A suction motor and fan assembly may be is positioned downstream of and below the pre-motor filter, a post motor filter may be positioned downstream of the suction motor and fan assembly and in the lower end of the hand vacuum cleaner. A clean air outlet may be positioned below the suction motor and fan assembly whereby air travels downwardly from the suction motor and fan assembly and through the post motor filter to the clean air outlet.

A hand vacuum cleaner may include a suction motor and fan assembly that is positioned downstream of a pre-motor filter and in an upper end of the hand vacuum cleaner. A post motor filter may be positioned downstream of the suction motor and fan assembly and may be in the lower end of the hand vacuum cleaner. The clean air outlet may be positioned below the suction motor and fan assembly whereby air may travel generally downwardly from the suction motor and fan assembly and through the post motor filter to the clean air outlet.

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, an air guide configured to guide the air passing through the filter part in an inner region of the filter part to a suction motor configured to generate suction force, 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.

A vacuum cleaner, movable over a surface, includes a suction source, a suction port, and a dustpan attachment removably coupled to the suction port. The dustpan attachment includes a housing, a vacuum port, and a recess defined within the housing. The housing includes a top wall and a plurality of walls extending from the top wall to a bottom edge configured to contact the surface. The vacuum port extends through at least the top wall or one of the plurality of walls and is coupled to the suction port. When the bottom edge contacts the surface, the recess cooperates with the surface to form a suction channel having a suction inlet formed in a front of the housing and in communication with the vacuum port. The housing defines first and second ends. The bottom edge includes a sealing material that contacts the surface continuously between the first and second ends.

The cleaner includes a main body having an opening, a suction motor accommodated in the main body and configured to generate suction force, an opening cover separably coupled to the main body and configured to cover the opening, and a filter mechanism accommodated in the main body through the opening and configured to filter foreign substances of air discharged by the suction motor. When the opening cover is separated from the main body, at least a portion of the filter mechanism protrudes to the outside of the main body through the opening. While the opening cover is coupled to the main body, at least a portion of the filter mechanism protruding to the outside of the main body is pressed by the opening cover so as to be accommodated in the main body.

A vacuum cleaner including a cleaner body; and a dust collector provided in the cleaner body, wherein the dust collector includes an outer case forming a side appearance of the dust collector; a first cyclone provided within an outer case to filter dust and foreign matter from air introduced into the dust collector; a second cyclone accommodated within the first cyclone to separate fine dust from the air introduced into the first cyclone; and an upper cover mounted on a top of the outer case to cover the first and second cyclones and having an intake guide configured to introduce air into the outer case and an exhaust guide configured to discharge air from which fine dust is separated by the second cyclone.

A vacuum cleaner, including a cleaner body; and a dust collector provided in the cleaner body, wherein the dust collector includes a first cyclone provided within an outer case to filter foreign matter and dust from air introduced into the dust collector; a second cyclone accommodated within the first cyclone to separate fine dust from the air introduced into the first cyclone; and a screw surrounding part of the first cyclone, and configured to be rotatable in at least one direction with respect to the first cyclone, wherein the screw includes a pillar that spans a height of the mesh filter; and a scraper provided on an inner surface of the pillar facing an outer surface of the mesh filter, and configured to sweep off dust and foreign matter accumulated on the mesh filter during the rotation of the screw.

A hand vacuum cleaner may include a suction motor and fan assembly that is positioned downstream of a pre-motor filter. A post motor filter may be positioned downstream of the suction motor and fan assembly and may be in the lower end of the hand vacuum cleaner and an energy storage member may be in an upper end of the handle.

A surface cleaning apparatus includes a floor cleaning unit and a portable surface cleaning unit. The floor cleaning unit includes a surface cleaning head and an upper section moveably mounted to the surface cleaning head between an upright storage position and a rearwardly inclined floor cleaning position. The portable surface cleaning unit is connectable to the floor cleaning unit, and includes a portable surface cleaning unit air inlet connectable in air flow communication with the floor cleaning unit, a main body, an air treatment member, a suction motor, a handle and a capacitor. A remote charger is provided wherein the capacitor is rechargeable at a rate of at least 4 C.

A vacuum cleaner filtration system having a primary separation system and a filter downstream of the primary separation system. The filter has an upstream side to receive an airflow exiting the primary separation system, and a downstream side fluidly opposite the upstream side. The system has a vacuum fan, a primary suction path between the filter's downstream side and the vacuum fan, a valve in the primary suction path and configured to selectively position to block the primary suction path and create a closed passage at the filter's downstream side, and a secondary suction path between the filter's upstream side and the vacuum fan. A secondary filtration system is in the secondary suction path to separate dirt from an airflow passing therethrough, to thereby clean dirt from the filter's upstream side. A nozzle may be provided to concentrate the air flow as it enters the secondary suction path.
