A hand vacuum cleaner has a first air treatment stage comprising a first stage air treatment chamber and a first stage longitudinal axis extending between the front and rear ends of the first air treatment stage and a second air treatment stage downstream from the first stage air treatment chamber, the second air treatment stage a second stage air treatment chamber and a second stage dirt collection chamber that is exterior to the second stage air treatment chamber. The second stage dirt collection chamber extends forward of the second stage air treatment chamber. A plane that is transverse to the first stage longitudinal axis extends through the first stage air treatment chamber and the second stage dirt collection chamber, and the first stage air treatment chamber and the second stage dirt collection chamber are concurrently openable.

A vacuum cleaner including a cleaner body; and a dust collector provided in the cleaner body, wherein the dust collector includes an outer case forming a side appearance of the dust collector; a first cyclone provided within an outer case to filter dust and foreign matter from air introduced into the dust collector; a second cyclone accommodated within the first cyclone to separate fine dust from the air introduced into the first cyclone; and an upper cover mounted on a top of the outer case to cover the first and second cyclones and having an intake guide configured to introduce air into the outer case and an exhaust guide configured to discharge air from which fine dust is separated by the second cyclone.

A cleaner includes: a suction unit that guides dust and air; a main body that includes a dust separation unit for separating dust from air guided through the suction unit; a main body terminal mounted on the main body; a handle unit that is slide-coupled to the main body; and a handle terminal mounted on the handle unit and is connected to the main body terminal when the handle unit is slide-coupled to the main body.

A hand vacuum cleaner has a cyclone assembly positioned in the air flow path, the cyclone assembly comprising a cyclone chamber, the cyclone chamber having a front end, a rear end, a cyclone axis of rotation extending between the front and rear ends, a cyclone air inlet and a cyclone air outlet provided at the rear end of the cyclone chamber, wherein the rear end is rotationally moveable by a rotational mount between a closed position in which the cyclone is closed and an open position wherein a rear portion of the cyclone is open.

A robot cleaner is provided. The robot cleaner includes a main body, a suction motor provided in the main body to generate a suction force, and a dust collector removably coupled to the main body to collect dust contained in air suctioned by the suction motor. The dust collector includes a first chamber to which the air, which is suctioned into the main body by the suction motor, is introduced, the first chamber including a filter to filter out dust in the suctioned air, and a second chamber arranged side by side with the first chamber, the second chamber including a connection port to which air, which is filtered b the filter in the first chamber, is introduced, and a cyclone dust separator to separate dust from the introduced air.

A vacuum cleaner has two cyclonic cleaning stages. The air outlet of the first cyclonic cleaning stage is located at the air inlet end of the second cyclonic cleaning stage. The axially opposed end of the second cyclonic cleaning stage is openable.

A cleaner includes: a suction motor that generates suction force; a dust separation unit that separates dust from air sucked by the suction force; a motor housing that covers the suction motor; a flow guide that surrounds an outer side of the motor housing and guides air discharged from the dust separation unit to the suction motor; and a body that forms an external appearance by surrounding the flow guide and guides air discharged from the suction motor together with the flow guide.

A debris cleaning mechanism and a cleaning device, comprising a driving mechanism, a transmission mechanism, and a debris scraping mechanism. The transmission mechanism comprises a gear box, and the gear box is connected to the driving mechanism by means of an input shaft and connected to the debris scraping mechanism by means of an output shaft; the debris scraping mechanism comprises a debris scraping body, and the output shaft is in transmission connection with the debris scraping body to drive the debris scraping body to move; the debris scraping body is provided with a first and/or a second debris scraping strip. The cleaning device comprises a debris barrel, a debris barrel cover, the debris cleaning mechanism, and a cover opening mechanism; when a rack of the transmission mechanism moves to a preset position along the axial direction of the debris barrel, the cover opening mechanism is pushed to move.

A vacuum cleaner has a housing and a cover moveably mounted to the housing between a closed position and an open position. A filter is carried by the cover and includes an upstream surface and a downstream surface through which working air passes. When a user of the vacuum cleaner opens the cover, the upstream surface of the filter can be seen by the user.

A dust collecting apparatus is provided. The dust collecting apparatus according to an embodiment includes a dust collecting case including a dust outlet to discharge collected dust, a cyclone member configured to rotate and move linearly in the dust collecting case to be detachable from and attachable to the dust collecting case, a discharge cover configured to rotate and move linearly together with the cyclone member, and detachable from and attachable to an upper part of the dust collecting case to open and close the dust outlet, and a sealing member having elasticity disposed between the dust collecting case and the discharge cover. The discharge cover rotates along a horizontal direction of the dust collecting case to detach from the upper part of the dust collecting case and form a space between the sealing member and the dust collecting case.
