A handheld vacuum cleaner including a housing having a front end, a back end, a first side, and a second side, the housing further including a handle along a handle axis. A suction nozzle is along a suction nozzle axis that extends in a direction from the front end toward the back end. The handheld vacuum further includes a suction source operable to generate an airflow through the vacuum cleaner from the suction nozzle through a cyclonic separator to a clean air exhaust. A battery that supplies power to the suction source and the battery is coupled to the housing adjacent an end of the handle. The handle extends between the battery and the cyclonic separator.

The invention relates to a vacuum cleaning device, including a body, a dust cup, and an unlocking mechanism for unlocking and locking the dust cup. The body is provided with a vacuum cleaning channel, a filter is provided in the dust cup, the unlocking mechanism is configured to have a locking state and an unlocking state, and when the unlocking mechanism is in the locking state, the dust cup and the body are locked together in a sealing manner, and the vacuum cleaning channel is in communication with the filter and the dust cup such that the filter and the dust cup are in a working state; and when the unlocking mechanism is in the unlocking state, the dust cup and the filter are automatically disengaged from the vacuum cleaning channel to an easy-to-take state.

A cleaner includes: a suction unit that guides air and dust; a main body connected with the suction unit and including a dust separation unit that separates dust from air, and a dust container that stores dust separated by the dust separation unit, at least a portion of the dust container being transparent or translucent; a handle unit connected to the main body and has a battery; a power receiving component disposed in the main body to be supplied with power from the battery; wires that are connected to the power receiver; and a cover member coupled to the main body and disposed between the main body and the wires to prevent the wires from being seen from the outside of the dust container.

A cleaner includes: at least one cyclone configured to separate dust from suctioned air; a dust container configured to store the dust separated by the at least one cyclone; a dust compressor provided inside the dust container; and a lifter configured to move the dust compressor upward and downward.

A cleaner includes a suction unit, a main body including a cyclone unit for separating dust from air suctioned through the suction unit, and a dust container that stores dust separated in the cyclone unit below the cyclone unit. A filter unit is disposed inside the cyclone unit for filtering the air, and a movable unit disposed inside the cyclone unit includes a cleaning part for cleaning the outer circumference of the filter unit. An operation unit disposed outside the main body moves the movable unit and the cleaning part to remove dust from the outer surface of the filter unit.

A bucket lid for a cyclone dust collector is configured to fit onto a standard pail or bucket, with a circumferential rim forming an outer edge of the lid, a central mounting disk onto which the cyclone is mounted, and a series of baffles extending circumferentially around the lid between the mounting disk and the rim. These baffles extend downward into the bucket to interfere with swirl in the bucket from dust discharged from the cyclone. The baffles may be radial ribs alternating with ramped coffers. The lid may be formed of anti-static polypropylene.

A surface cleaning apparatus comprises an air treatment member having an air treatment chamber. A moveable member is positioned in the air treatment chamber. A handle is drivingly connected to the moveable member by a driving linkage wherein part of the driving linkage extends through an opening in an end wall of the air treatment member, whereby the moveable member is longitudinally translatable through at least a portion of the chamber.

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. When the air treatment member assembly is mounted to the hand vacuum cleaner in an operating position, the air treatment member assembly is positioned in the volume and the air treatment member is positioned in the air flow path.

A hand vacuum cleaner has a body portion housing a suction motor. An air treatment member assembly comprises an air treatment member assembly body, a rear door and an air treatment member. The air treatment member has a front end, a rear end, an air inlet and an air outlet provided at the rear end of the air treatment member. The air treatment member assembly is moveable to an emptying position. The rear door is moveable between a closed position and an open position, and the rear door houses a pre-motor filter that is external to the air treatment member.

A hand vacuum cleaner has a main body housing a suction motor, an air treatment member having a front end and a rear end with a central longitudinal axis extending between the front and rear ends and a bleed valve having a bleed air flow path that extends from a bleed air inlet to a bleed air outlet. The hand vacuum cleaner has right and left laterally opposed sides that are spaced apart in a direction transverse to the central longitudinal axis, and the bleed air inlet and the bleed air outlet are transversely spaced apart.
