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 cyclonic dust filter device comprises a trunk, at least one first retaining wall, and at least one second retaining wall. The trunk comprises a channel, an air inlet end and an air outlet end disposed at two ends of the channel, and a dust filter hole communicating with the channel. The first and second retaining walls are respectively disposed correspondingly to the dust filter hole. When a dust-containing airflow to-be-filtered enters the channel from the air inlet end, the dust-containing airflow forms a centrifugal airflow that contains the dust and is thrown out of the channel at a position of the dust filter hole. The first and second retaining walls are respectively disposed on a traveling path of the centrifugal airflow, so that the centrifugal airflow sequentially strikes the first and second retaining walls to change the traveling direction and then discharges dust free clean air.

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 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.

An all in the head surface cleaning apparatus may include a surface cleaning head having an air flow path extending from a dirty air inlet to a clean air outlet. The surface cleaning head may include a cyclone including a cyclone chamber and a longitudinal cyclone axis. The surface cleaning head may include a pre-motor filter chamber housing a pre-motor filter. The pre-motor filter may have an upstream face, a downstream face and a pre-motor filter axis that is generally parallel to the upstream and/or downstream face. The surface cleaning apparatus may have a suction motor having a first end, a second end, a suction motor inlet and a suction motor axis extending between the first and second ends. The cyclone axis may be oriented generally transverse to a forward direction of travel and the pre-motor filter axis may be generally parallel to the forward direction of travel.

An all in the head surface cleaning apparatus can include a surface cleaning head having an air flow path extending from a dirty air inlet to a clean air outlet. The surface cleaning head can include a cyclone assembly comprising a cyclone chamber and a dirt collection chamber. The cyclone chamber may have a longitudinal cyclone axis, a cyclone air inlet and a cyclone air outlet. The dirt collection chamber may be moveable between an in use position and an emptying position. The surface cleaning head may include a pre-motor filter chamber and a suction motor. At least one of the pre-motor filter and a pre-motor filter chamber may be visible when the dirt collection chamber is in the emptying position. An upper portion may be mounted to the surface cleaning head between a storage position and a floor cleaning position, and may include a drive handle.

An autonomous vacuum cleaner includes an outer housing and a separator assembly that is removably received by the autonomous vacuum cleaner. A portion of the separator assembly defines a portion of at least two walls of the outer housing.

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 vacuum cleaner that includes: a cleaner body; a wheel; a dust container; a cover member that is configured to (i) rotate, about an axis that is outside of a plane of the cover member, between a first position and a second position and (ii) cover, based on the cover member being located at the first position or the second position, the first opening of the cleaner body and a portion of the dust container; a cover member coupling portion that couples the cover member to the cleaner body and that is configured to rotate about the second axis with the cover member; a suction nozzle that is coupled to the dust container and that is configured to guide dust into the dust container; and a display that is coupled to the cover member and that is configured to display operating information of the vacuum cleaner is disclosed.
