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 dust cup assembly (100) and a handheld cleaner (1000) having the same are provided. The dust cup assembly (100) includes: a cup casing (1); a device housing (2) configured as a tube shape and disposed in the cup casing (1), wherein an outer end face of the device housing (2) at an axial side thereof abuts against or extends beyond a partial inner surface of the cup casing (1), and a dust removal chamber (A1) is defined between an inner surface of the cup casing (1) and an outer peripheral surface of the device housing (2) and surrounds the device housing (2) along a circumferential direction of the device housing (2); and a negative pressure device (3) located within the device housing (2) and enabling dusty air to enter the dust removal chamber (A1) for dust and air separation.

An upright vacuum cleaner has a handle by which it can be manoeuvred across a floor in a floor cleaning mode, the handle being part of a releasable suction wand which can be used in an above-floor cleaning mode. The suction wand has a first section which comprises the handle, a second section, and a third section which comprises a suction nozzle. The first section is movable relative to the second section between floor cleaning and above-floor cleaning positions. The third section is extendable and retractable relative to the second section. The suction wand has a linkage which is configured to couple movement of the first section towards one of said positions, and extension or retraction of the third section.

A vacuum cleaner comprising a cyclonic separating apparatus including a dirty air inlet, a main body connected to the cyclonic separating apparatus and a motor and fan unit for generating an airflow through the cyclonic separating apparatus from the dirty air inlet to a clean air outlet, wherein the cyclonic separating apparatus includes at least a first cyclonic cleaning stage and an elongate filter arranged fluidly downstream from the first cyclonic cleaning stage, the elongate filter being housed in a duct at least partially surrounded by the first cleaning stage, and wherein the filter comprises an inlet portion and a filter portion defining a generally tubular filter chamber, the inlet portion including one or more radially facing inlets to permit air to flow into the inlet portion in a radial direction from where the air flows from the inlet portion to the filter chamber in an axial direction.

A hand vacuum cleaner comprises a cyclone, a conical pre-motor filter that is positioned rearward of the cyclone and a suction motor. The pre-motor filter has a front end that faces towards the cyclone air outlet. The conical pre-motor filter has an open interior volume, an outer surface, which is an upstream surface of the pre-motor filter, and an inner surface, which is a downstream surface of the pre-motor filter.

A vacuum cleaner includes an upright handle assembly, a foot assembly adapted to be moved along a surface to be cleaned and having a suction nozzle, a multi-axis joint swivelably mounting the upright handle assembly to the foot assembly and defining a first axis about which the upright handle assembly twists relative to the foot assembly and a second axis about which the upright handle assembly pivot relative to the foot assembly, and a detachable vacuum module supported on the upright handle assembly by the module platform.

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.

The cleaner includes a suction inlet configured to guide air and dusts, a main body including a first cyclone unit configured to separate the air and the dusts, which are suctioned through the suction inlet, from each other, and a dust separation module separably connected to the main body and including a second cyclone unit configured to separate the dusts from the air discharged from the first cyclone 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.
