A hand vacuum cleaner has a cyclone unit, a front electrical connector and electrical conductors that extend from the front electrical connector to a source of power. The electrical conducts extend along a portion of a wall of the cyclone unit. When a cleaning tool is connected to the hand vacuum cleaner, the cleaning tool is connected in air flow communication with the dirty air inlet and the cleaning tool is electrically connected to the front electrical connector.

Provided is a vacuum cleaner including a base configured to form a lower surface of a cleaner body; moving wheels provided at both side surfaces of the cleaner body and rotated for travel of the vacuum cleaner and also configured to support the cleaner body to be rotated in normal and reverse directions; and a dust container installed at a front of the moving wheels and configured to collect suctioned dust, wherein the base includes a center portion; a first half portion configured to extend to be inclined upward from a front end of the center portion; and a second half portion configured to extend to be inclined upward from a rear end of the center portion, and a rotating center of the moving wheels is located between the first half portion and the second half portion.

Provided is a cleaner including a dust collecting device for separating dust from air, wherein the dust collecting device includes a dust collecting case having a dust discharging port opened to discharge the collected dust; a discharge cover coupled to one side of the dust collecting case to open and close the dust discharge port; and a sealing member provided to extend from an inner surface of the dust collecting case to a coupling surface of the dust collecting case while being in contact with the dust collecting case and thus to be sealed when the dust discharging port is closed.

A dust-air separation device and vacuum cleaner comprises a housing with an air inlet channel, a cyclone separation chamber, and a dust collection chamber, the air inlet channel and the dust collection chamber are connected to the cyclone separation chamber, and an air outlet is formed on the housing; the inner peripheral wall of the cyclone separation chamber is provided with an air deflector extending along the flow direction of the airflow in the cyclone separation chamber. A first separator and the second separator are respectively located on opposite sides of the air deflector along the axial direction of the cyclone separation chamber, and the first separator and the second separator are both connected to the air outlet. The dust-air separation device reduces filter clogging and sudden drops in suction power such that the device has better vacuuming performance.

Provided is a cleaning device including a vacuum cleaner including a dust collector into which dirt and dust is collected, a docking station connected to the dust collector and having a long axis extending in a first direction, and the docking station includes a docking part coupled to the dust collector to remove dirt and dust collected in the dust collector, a sucking device sucking up the dirt and dust and inside air in the dust collector docked with the docking part through the docking part, and a circulation duct arranged for the air sucked up by the sucking device to be circulated to the docking part.

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.

In general, the present disclosure is directed to a hand-held surface cleaning device that includes a relatively compact form-factor to allow users to store the same in a nearby location (e.g., in a drawer, in an associated charging dock, on a table top) for easy access to perform relatively small cleaning tasks that would otherwise require retrieving a full-size vacuum from storage. A hand-held surface cleaning device consistent with aspects of the present disclosure includes a body (or body portion) with a motor, power source and dust cup disposed therein. The body portion also functions as a handgrip to allow the hand-held surface cleaning device to be operated by one hand, for example.

A hand vacuum cleaner has a cyclone unit and a pistol grip handle. The cyclone unit comprises a cyclone chamber with a cyclone axis of rotation extending between the front and rear ends of the cyclone chamber. When the hand vacuum cleaner is oriented with the cyclone axis of rotation extending horizontally, the inlet conduit is located at a lower side of the hand vacuum cleaner, the pistol grip handle is provided on a lower side of the main body and the pistol grip handle extends upwardly from a lower end of the pistol grip handle to an upper end of the pistol grip handle.

A hand vacuum cleaner has a cyclonic unit comprising a first cyclonic stage and a second cyclonic stage. The front end of the first cyclonic stage has a front door that is moveable between a closed position and an open position. A latch secures the front door in the closed position. The openable front door has a door first end which is rotatably mounted to a front end of the cyclone unit. The latch and the handle are provided on one side of the hand vacuum cleaner when the openable front door is in a closed position and, when the hand vacuum cleaner is oriented such that the cyclone axis is horizontal and the upper side is above the lower side, the door first end is vertically spaced from the one side.

A hand vacuum cleaner has a cyclonic unit comprising a first cyclonic stage and a second cyclonic stage, the first cyclonic stage comprising a cyclone. An openable door opens the cyclone when the door is in an open position. The front door has a diameter and the rear end of the first cyclonic stage has a diameter that is generally equal to the diameter of the front door.
