A dust collector for a vacuum cleaner disclosed herein includes an outer case forming a lateral appearance of the dust collector, and provided with a first cyclone unit capable of filtering out dust from externally-introduced air and allowing an introduction of the dust-filtered air therein, and an upper case coupled to an upper portion of the outer case to cover the first cyclone unit, the outer case including a second cyclone unit capable of separating fine dust from the air introduced into the first cyclone unit, and a fine dust collecting unit capable of collecting the fine dust separated through the second cyclone unit, wherein the second cyclone unit includes a left cyclone portion and a right cyclone portion disposed at both left and right sides of the fine dust collecting unit and each having outlets, each of the outlets communicating with an inside of the fine dust collecting unit.

A hand vacuum cleaner with a finger grip area that is provided between a forward side of the handle and a rear side of the main body, and wherein the suction motor is positioned between the cyclone and the finger grip area and an axis that extends between the front of the cyclone and the handle extends through the suction motor.

A surface cleaning apparatus comprises an air treatment chamber, a pre-motor filter and a suction motor. The suction motor and the pre-motor filter are laterally spaced from the air treatment chamber. When the surface cleaning apparatus is positioned on a horizontal surface with the upper end of the air treatment chamber above the lower end of the air treatment chamber, the pre-motor filter is positioned at a higher elevation than the suction motor.

A surface cleaning apparatus has a surface cleaning head having a pivoting connector, an upper end of the pivoting connector providing an air outlet of the surface cleaning head. A support consisting of an upflow duct is pivotally mounted to the surface cleaning head by the pivoting connector. A surface cleaning unit is vertically removably mounted to an upper end of the support. The surface cleaning unit comprises a cyclone unit, a pre-motor filter, a suction motor and flexible hose.

A vacuum cleaner has an upright support structure pivotally mounted to a cleaning head. A portable surface cleaning unit is removably mounted to the upright support structure. The portable surface cleaning unit has a cyclone chamber, a dirt collection chamber exterior to the cyclone chamber and a suction motor. When the portable surface cleaning unit is mounted to the upright support structure and the upright support structure extends upwardly from the cleaning head, the upper end wall of the dirt collection chamber and the cyclone chamber end wall are an openable upper wall of the portable surface cleaning unit.

A cyclone separator useable in a surface cleaning apparatus comprises a cyclone chamber and a dirt collection chamber exterior to, and surrounding at least a portion of the cyclone chamber. The dirt collection chamber is in communication with the cyclone chamber via a dirt outlet. An air flow passage extending to the cyclone air inlet travels generally axially through the dirt collection chamber.

A cleaner includes a housing having an introduction opening through which air is introduced, a filtering unit configured to be mounted in an inner space of the housing, and defining a dust collection space between the filtering unit and an inner surface of the housing, and a cleaning unit configured to surround the filtering unit, and configured to be raised and lowered inside the dust collection space along with a manipulation unit, wherein, when the cleaning unit is in an initial position, at least a portion of the cleaning unit is connected to an air introduction path extending from the introduction opening to form a guide flow path to guide a flow of introduced air.

A surface cleaning apparatus has a cyclone chamber having a longitudinal cyclone axis of rotation wherein the dirt outlet is defined by a gap between the sidewall of the cyclone and a plate positioned at the dirt outlet end of the cyclone.

A partition skirt device for a cleaning apparatus includes an inner ring and a skirt body. The skirt body includes: a root connected to the inner ring; an edge part arranged at an end of the skirt body away from the inner ring; and a plurality of collapsing parts arranged at intervals between the root and the edge part along a circumferential direction of the skirt body, and each extending along a radial direction of the skirt body. Along a thickness direction of the skirt body, the collapsing part protrudes relative to the skirt body on a first side surface of the skirt body and is recessed relative to the skirt body on a second side surface of the skirt body. On the first side surface of the skirt body, a size of a portion of the collapsing part protruding from the skirt body gradually decreases from the root to the edge part.

A dust scraping device for a cleaning apparatus includes a dust cup and a removable cyclone separation unit arranged in the dust cup. The dust scraping device includes a dust scraping member. The dust scraping member has a connection portion extending in a removal direction of the cyclone separation unit, and a dust scraping portion extending to an interior of the dust cup in a direction perpendicular to the removal direction and slidably abutting against the cyclone separation unit. The dust scraping device is mounted at the dust cup, and the dust scraping portion scrapes off at least part of debris on an outer side of the cyclone separation unit when the cyclone separation unit is removed from the dust cup.
