Abstract: 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.

Abstract: An upright cleaner removes dust from a drum brush. The upright cleaner includes a case having a suction port, a drum brush rotatably provided in the case to sweep and guide foreign matter to the suction port, a dust removal unit provided in the case so that the dust removal unit is moved between a first position where one side of the dust removal unit contacts the drum brush and a second position where the side of the dust removal unit is separated from the drum brush, and a lever connected to the dust removal unit to actuate the dust removal unit.

Abstract: A cleaner including a case, a brush provided in the case so that the brush rotates to sweep foreign matter, a dust removal unit including a bar-type body and a dusting part directly extending from the bar-type body. The dust removal unit is moveable between a first position where the dusting part contacts the brush and a second position where the dusting part is separated from the brush. The cleaner also includes a first part directly connected to the bar-type body and a second part integrally formed with the first part and extending from an end of the first part. While a force is applied to the second part, the force is transmitted through the first part to the dust removal unit such that the dusting part moves from the second position to the first position.

Abstract: A cleaning apparatus including a brush to sweep up dust on the floor via rotation thereof, and an elevating device to vertically adjust a height of the brush. The elevating device includes an elevating motor to generate rotation force, a cam configured to be rotated by the elevating motor and serving to vertically move the brush, and a rotation switch configured to rotate in a given direction along with the cam and serving to sense a position of the brush. The cleaning apparatus is structurally simplified as a resulting of using an Alternating Current (AC) motor as the elevating motor.
