A cleaner of the present disclosure comprises: a suction part; a main body comprising a body and a body cover for opening and closing the lower side of the body, the body comprising a cyclone part for separating dust from dust masses suctioned through the suction part and a dust container for storing the dust separated by the cyclone part; a handle part coupled to the main body; a filter part disposed inside the body, and filtering air, separated from the dust in the cyclone part; a movable part capable of moving inside the body along a space between the outside of the filter part and the inner circumferential surface of the body; an operation part disposed at the outside of the main body to move the movable part; and a delivery part penetrating through the main body, and connecting the movable part to the operation part.

A cyclone assembly for a surface cleaning apparatus has a first cyclonic cleaning stage having a first end moveable between a closed position in which a first stage cyclone chamber and a first stage dirt collection chamber are closed and an open position in which the first stage cyclone chamber and the first stage dirt collection chamber are open, and a second cyclonic cleaning stage having a second end moveable between a closed position in which a plurality of second stage cyclone chambers and at least one second stage dirt collection chamber are closed and an open position in which the second stage cyclone chambers and the second stage dirt collection chamber are open.

A cyclone assembly includes a first cyclonic cleaning stage. The first cyclonic cleaning stage includes at least one first stage cyclone having a first stage cyclone chamber. Each first stage cyclone chamber has a height extending between a first stage cyclone chamber air inlet and a first stage cyclone dirt outlet. The cyclone assembly also includes a second cyclonic cleaning stage downstream from the first cyclonic cleaning stage. The second cyclonic cleaning stage includes a plurality of second stage cyclones in parallel. Each of the plurality of second stage cyclones has a height extending between a second stage cyclone chamber air inlet and a second stage cyclone dirt outlet. The second cyclonic cleaning stage has a larger number of second stage cyclones than the first cyclonic cleaning stage, and the height of each second stage cyclone chamber is greater than the height of each first stage cyclone chamber.

A cyclone assembly for a surface cleaning apparatus has an openable lower end, a first cyclonic cleaning stage, a second cyclonic cleaning stage, and an airflow passage from the first cyclonic cleaning stage to the second cyclonic cleaning stage. The lower end is moveable to an open position in which at least a portion of the air flow passage is opened.

A surface cleaning apparatus has a cyclone chamber provided in an air flow path. The cyclone chamber has a screen assembly with an outlet section, a longitudinally spaced apart distal section and a longitudinally extending porous section. The outlet section includes a non-porous member extending longitudinally inwardly an outlet section length from an outlet end of the outlet section to a longitudinally inwardly positioned inlet end of the outlet section. The outlet end of the outlet section overlies a cyclone air outlet. The porous section extends longitudinally inwardly from an outlet end of the porous section that is located at the inlet end of the outlet section. The distal section has a distal section length in the longitudinal direction that is greater than the cyclone outlet port length.

A cyclone assembly for a surface cleaning apparatus has two cyclonic stages wherein the second cyclonic cleaning stage comprises a second stage dirt collection region and at least a portion of the second stage dirt collection region is positioned longitudinally above and overlying a first stage cyclone chamber.

The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner including a case detachably provided at a cleaner body to accommodate dust and of which an upper surface and a lower surface are opened; a cyclone provided inside the case to separate the dust; an upper cover configured to shield the upper surface of the case and having a suction port through which the dust is suctioned and a discharge port through which air separated from the dust is discharged; an upper locker rotatably installed at an outer surface of the case and configured to selectively restrict the upper cover; a lower cover configured to shield the lower surface of the case; and a lower locker slidably installed at the outer surface of the case and configured to selectively push and open the lower cover.

A robot cleaner comprising: a cleaner body including a wheel unit and a controller controlling driving of the wheel unit a suction unit disposed in the cleaner body, the suction unit sucking air containing dust and a sensing unit disposed at the front of the cleaner body in which the suction unit is disposed, wherein the sensing unit includes a first sensing part disposed respectively inclined with respect to side and top surfaces at an upper corner portion of the cleaner body to simultaneously photograph front and upper parts of the cleaner body.

A robot cleaner comprising: a cleaner body including a dust container accommodation part formed to be recessed toward the front from the rear thereof; a suction unit mounted in the cleaner body to suck air containing dust; a dust container accommodated in the dust container accommodation part, the dust container collecting dust filtered from sucked air; and an exhaust port formed at an end portion of one rear side of the cleaner body, which surrounds the dust container accommodation part, to discharge filtered air to the outside, the exhaust port disposed along the height direction of the cleaner body.

A robot cleaner comprising: a first housing including a controller and a driving wheel of which driving is controlled by the controller; a second housing provided at one side of the first housing, the second housing having a brush module or mop module mounted thereto; a front bumper provided at a front portion of the second housing, the front bumper configured to be movable to the inside of the second housing when the front bumper is in contact with an obstacle; at least one sensing means provided at the inside of the front bumper to sense a movement of the front bumper to the inside of the second housing; side bumpers respectively provided at left and right side portions of the second housing, the side bumpers each being configured to movable to the inside of the second housing when the side bumper is in contact with an obstacle; and a link member provided at the inside of the side bumper to allow the side bumper and the front bumper to interlock with each other such that, when the side bumper is moved to the inside of the second housing, at least one portion of the front bumper is moved together with the side bumper to the inside of the second housing.
