A cleaner comprising: a main body that forms an external shape, and including: a suction unit configured to guide air containing dust into the main body; a first cyclone unit configured to separate dust from air suctioned through the suction unit; a second cyclone unit configured to separate dust from air discharged from the first cyclone unit; a dust container that is separably combined with the main body and configured to store dust separated from air by the first and second cyclone units (110, 130); a dust container cover that is configured to open and close the dust container; and a suction motor configured to generate suction force to thereby suction air; a handle unit, disposed behind the dust container, including a handle and a battery housing provided at a lower side of the handle and configured to receive a battery; and an operating member configured to operate the dust container cover to be rotated; wherein a hinge for rotating the dust container cover is positioned opposite to the battery housing with respect to a center axis of cyclone flow of the first cyclone unit; characterized in that: the suction motor is located over the second cyclone unit with respect to a center axis of cyclonic flow of the first cyclone unit; and the dust container is positioned opposite to the suction motor with respect to the second cyclone unit. a main body that forms an external shape, and including: a suction unit configured to guide air containing dust into the main body; a first cyclone unit configured to separate dust from air suctioned through the suction unit; a second cyclone unit configured to separate dust from air discharged from the first cyclone unit; a dust container that is separably combined with the main body and configured to store dust separated from air by the first and second cyclone units (110, 130); a dust container cover that is configured to open and close the dust container; and a suction motor configured to generate suction force to thereby suction air; a suction unit configured to guide air containing dust into the main body; a first cyclone unit configured to separate dust from air suctioned through the suction unit; a second cyclone unit configured to separate dust from air discharged from the first cyclone unit; a dust container that is separably combined with the main body and configured to store dust separated from air by the first and second cyclone units (110, 130); a dust container cover that is configured to open and close the dust container; and a suction motor configured to generate suction force to thereby suction air; a handle unit, disposed behind the dust container, including a handle and a battery housing provided at a lower side of the handle and configured to receive a battery; and an operating member configured to operate the dust container cover to be rotated; wherein a hinge for rotating the dust container cover is positioned opposite to the battery housing with respect to a center axis of cyclone flow of the first cyclone unit; characterized in that: the suction motor is located over the second cyclone unit with respect to a center axis of cyclonic flow of the first cyclone unit; and the dust container is positioned opposite to the suction motor with respect to the second cyclone unit. the suction motor is located over the second cyclone unit with respect to a center axis of cyclonic flow of the first cyclone unit; and the dust container is positioned opposite to the suction motor with respect to the second cyclone unit.
