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 dirt collecting box assembly includes a dirt collecting box and a separating device. The dirt collecting box defines a dirt inlet, an air outlet, and a cavity, and the cavity communicates between the dirt inlet and the air outlet. The separating device is installed in the cavity of the dirt collecting box and is close to a top of the cavity. The separating device communicates between the dirt inlet and the air outlet. The air outlet communicates a fan assembly, and the fan assembly is configured to generate negative pressure through the air outlet, such that waste water enters the separating device via the dirt inlet under the negative pressure, and enters the cavity of the dirt collecting box after solid-liquid separation of the separating device.

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 robotic cleaning system may include a robotic cleaner having a robotic cleaner dust cup and a docking station having a docking station dust cup configured to fluidly couple to the robotic cleaner dust cup. The docking station dust cup may include a first debris collection chamber, a second debris collection chamber fluidly coupled to the first debris collection chamber, and a filter fluidly coupled to the first debris collection chamber and the second debris collection chamber.

A vacuum cleaner may include a suction motor and a cyclonic separator fluidly coupled to the suction motor. The cyclonic separator may include a chamber and a first and a second vortex finder extending within the chamber. The first and second vortex finders may extend from opposing sides of the 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.

An apparatus having a first cyclonic stage having a dirt collection chamber external thereto wherein the cyclone and the dirt chamber are concurrently openable. A second cyclonic stage is downstream from the first cyclonic stage, a pre-motor filter is downstream from the second cyclonic stage and a suction motor is downstream from the pre-motor filter wherein the suction motor axis of rotation extends through the pre-motor filter chamber and the second cyclonic stage.

A hand vacuum cleaner is provided with a first cyclonic cleaning stage, a pre-motor filter and a fluid flow motor. The first cyclonic stage has a bottom end, an upper end spaced longitudinally from the bottom end along a first stage axis, an air inlet and an air outlet, the first cyclonic cleaning stage comprising a first cyclone chamber and a first dirt collection region, the first dirt collection region having an end wall at the bottom end that is openable to empty the first dirt collection region. The pre-motor filter is positioned downstream from the first cyclonic cleaning stage and spaced from the openable end wall of the first dirt collection region in a direction of the first stage axis. The fluid flow motor is downstream from the pre-motor filter. The pre-motor filter is removable in the direction of the central longitudinal axis through an opening in an upper end of the hand vacuum cleaner.

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.

A cleaner includes: a main body that forms an external shape; a dust container that is separably combined with the main body and stores dust separated from air; a dust container cover that is configured to open and close the dust container; a handle unit that is disposed behind the dust container; and an operating member that is configured to provide operation force to the dust container cover by moving in a first direction and to release a holding mechanism for preventing separation of the dust container from the main body by moving in a second direction opposite to the first direction.
