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 handy-stick type vacuum cleaner is disclosed. The disclosed vacuum cleaner comprises: a first part for collecting dust included in air suctioned to the inside through a suction hole; and a second part including a suction motor and a handle, wherein the first and second parts are hinge-connected so as to communicate with each other.

The present disclosure includes a first housing configured in a cylindrical shape, an inlet port provided to the first housing to suck air therein, an inlet pipe communicating with the inlet port and extending to a front side of the housing with a length-directional axis positioned side by side with a ground surface, a cyclone forming part provided to separate dust from air flowing into the first housing, a second housing communicating with the first housing and coupled to a rear side of the first housing, a fan provided with the second housing to provide a suction force to enable air to be sucked into the first housing through the inlet port, a battery provided to supply power to the fan, and a handle part including a handle base coupled to a top side of the first housing and a handle body connected to the handle base.

A surface cleaning apparatus has a cyclone bin assembly having a cyclone chamber. The cyclone chamber with a physical filtration member defining the cyclone air outlet. The physical filtration member has an outer wall wherein at least a portion of the outer wall is porous and a plurality of ribs spaced around the outer wall. The ribs have a radial outer side that is positioned radially outwardly of the outer wall.

A surface cleaning apparatus has a cyclone chamber and a dirt collection chamber exterior to the cyclone chamber. The cyclone chamber has a sidewall extending from a first end to an axially opposed second end. A dirt outlet communicating with the dirt collection chamber is provided in the sidewall at a location intermediate the first and second ends of the cyclone chamber.

A separation structure for a dust cup of a vacuum cleaner is provided and includes a main body and a separator. The separator is fixedly mounted in an internal space of the main body. The internal space of the main body is divided by the separator into a first chamber, a second chamber and a third chamber. The separator is provided with a through hole, an air intake portion and a plurality of sedimentation portions communicated with the air intake portion. The plurality of sedimentation portions are arranged around the air intake portion. A length of the air intake portion is smaller than a length of each of the plurality of sedimentation portions. The air intake portion is communicated with the second chamber, the plurality of sedimentation portions are communicated with the third chamber. The first chamber is communicated with the second chamber via the through hole.

A vacuum cleaner separation system having: a cyclone tube having a cyclone chamber and an inner wall having a substantially cylindrical appearance defining a center axis; an inlet channel offset with respect to the center axis for receiving dust laden air; a dust outlet for discharging dust from the cyclone tube; an air outlet for discharging air from the cyclone tube; and a helical member arranged within the cyclone tube in an opposite region of the cyclone tube with respect to the air outlet. The helical member defines or partly defines a helical passage around the center axis from the inlet channel to the cyclone chamber for generating a centrifugal flow in the cyclone chamber. The helical passage has a substantially constant cross sectional area and the helical passage is rotated 360° or less than 360° around the center axis.

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.

A robot vacuum comprises a main body including a suction part for suctioning dust, and a dust canister, attachable to and detachable from the main body, and which separates dust from the air suctioned through the suction part and stores same. The dust canister includes: a first chamber which separates dust from the air flowing in from the suction part and storing same, and which includes an inclined surface so that the lower area thereof becomes narrower than the upper area thereof; and a second chamber which includes a cyclone unit and which separates dust from the air flowing in from the first chamber and stores same, and the first chamber can further include ribs formed along the inclined surface to facilitate discharge of dust so as to prevent the dust stored in the first chamber from becoming stuck, due to bottlenecking, in the lower area of the first chamber.
