Claim 0:
1. A cleaner comprising:
a main body that defines an opening and extends in a longitudinal axis;
a suction motor that is disposed in the main body and configured to generate suction force to thereby suction air;
a dust separation unit that includes a first cyclone unit configured to generate cyclonic flow and a second cyclone unit configured to separate dust from air discharged from the first cyclone unit, an axis of the cyclonic flow being parallel to the longitudinal axis;
a pre-filter configured to filter air that flows into the suction motor; and
a filter unit that includes an exhaust filter, the exhaust filter being configured to filter air discharged from the suction motor, the filter unit being configured to be inserted into and separated from the main body through the opening,
wherein the filter unit is configured to be attached to the main body via rotation,
wherein the filter unit is configured to:
based on being rotated to be detached, move in a first direction parallel to the longitudinal axis of the main body and the axis of the cyclonic flow in a state in which the suction motor is disposed in the main body, and
based on being rotated to be attached, move in a second direction opposite to the first direction, and

wherein the pre-filter is configured to, based on the pre-filter moving in the first direction parallel to the longitudinal axis of the main body and the axis of the cyclonic flow, be separated from the main body in the state in which the suction motor is disposed in the main body.
