A wearable vacuum cleaner includes a harness configured to support the wearable vacuum cleaner on a user's back, a housing connected to the harness, a suction motor assembly disposed within the housing and operable to create a working airflow, and a collection bin configured to receive debris separated from the working airflow. The collection bin includes an opening adjacent a bottom portion of the collection bin and a lid moveably coupled to the collection bin to selectively cover the opening in a closed position and uncover the opening in an open position. The lid is movable to the open position to empty the contents of the collection bin through the opening while the collection bin remains attached to the housing.

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 cyclone separator. The cyclone separator is provided with a connecting ring, a plurality of arc blades, a plurality of flat plates, a conical tube and a cylindrical tube. Each arc blade has a top fixedly connected with the connecting ring and a bottom fixedly connected with a respective flat plate. The flat plates are fixedly mounted at a large end of the conical tube. A plurality of air inlets are formed by gaps defined by the connecting ring, the arc blades and the flat plates. The cylindrical tube is fixedly connected with and communicated with the conical tube. A small end of the conical tube is received in the cylindrical tube. An included angle between each arc blade and the respective flat plate is an obtuse angle.

A debris canister and filter assembly, which may be used in a vehicular vacuum cleaner, includes a debris canister having an inlet, an outlet, and a peripheral side wall. The peripheral side wall at least partially defines an interior space of the debris canister. A filter is disposed in the interior space of the debris canister, and includes filter media having a non-pleated portion and a pleated portion. The peripheral side wall forms a corner of the debris canister, and the filter media has a rounded-corner shaped to fit adjacent to the corner of the peripheral side wall.

A robot cleaner includes a main body, and a wheel unit including a wheel configured to movably support the main body. The wheel unit is installed in a suspension unit and configured to be movable upward or downward. The suspension unit is configured to absorb impact when the wheel unit moves upward or downward, and is installed in a lifting unit coupled to the main body. The suspension unit is configured to be raised or lowered relative to the lifting unit. The lifting unit includes a lifting drive motor including a rotatable shaft disposed in parallel with a direction in which the suspension unit is configured to be raised or lowered, and a transmission unit configured to transmit a rotation force of the lifting drive motor to the suspension unit.

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.

A surface cleaning apparatus comprises an air treatment chamber having a porous member at the air outlet. The air treatment chamber has a stationary portion and an openable portion, the openable portion is moveably mounted by a mount between a closed position in which the air treatment chamber is closed and an open position in which the air treatment chamber is open. The porous member is moveable concurrently with the openable portion. When the openable portion is in the closed position, the openable portion and the stationery portion abut along peripheral edges that extend along a length of the air treatment chamber sidewall.

A surface cleaning apparatus has a cyclone assembly that comprises a cyclone and a dirt collection chamber exterior to the cyclone. The cyclone has a cyclone axis of rotation and the cyclone assembly has first and second opposed ends with sides extending between the first and second ends. The cyclone axis of rotation extends axially through the first and second ends and one of the sides is openable.
