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 dust collector can be used with a hand-held power tool. The dust collector includes a housing, a telescoping suction pipe coupled to the housing, and a suction fan positioned within the housing and operable to generate a vacuum in the suction pipe. The suction pipe is configured to telescope toward and away from the housing. The suction pipe includes an outer pipe supported by the housing, and an inner pipe slidably received into the outer pipe.

A robot cleaner provided with a shutter to open or close an inlet of a dust box when the dust box is separated from a body of the robot cleaner. Another robot cleaner, which docks with an automatic exhaust station, is also disclosed, together with the automatic exhaust station. The latter robot cleaner includes a shutter to be automatically opened by air discharged from the automatic exhaust station in a docked state of the robot cleaner to exhaust dust from the dust box, in order to allow even heavy dust to be easily exhausted.

A hatch mechanism for a pre-separator 120, the mechanism comprising an aperture having a perimeter arranged in a plane, and at least three elongated obturator elements pivotably attached along the perimeter at respective hinge ends, each obturator element comprising a distal end arranged opposite to the hinge end along the extension direction of the obturator element, wherein adjacent obturator elements arranged along the perimeter are connected by foldable joining members arranged to guide the distal ends to a common intersection point distanced from the plane, whereby the obturator elements are arranged to fold about respective hinge ends to a position of mutual support to close the hatch mechanism.

A vacuum cleaner includes: a dust canister; a cover rotatably coupled to the dust canister; an filter assembly mounted inside the dust canister and configured to be exposed by an opening of the cover; and a crevice tool coupling to an air entrance of the dust canister or an extension pipe connected to the air entrance. The filter assembly includes an opening portion opened toward the cover, and a protrusion portion protruding from an inner circumferential surface of the opening portion. The crevice tool includes a catching rib caught on the protrusion portion according to insertion and rotation of the crevice tool in the opening portion. The filter assembly is configured to withdraw from the dust canister together with the crevice tool based on withdrawing of the crevice tool to the outside of the dust canister in a state in which the catching rib is caught on the protrusion portion.
