1. A cleaner comprising:
a suction unit configured to suction air and dust;
a suction motor configured to generate suction force to thereby suction the air and the dust through the suction unit;
an impeller connected to the suction motor and positioned above the suction motor; and
a dust separation unit configured to separate the dust from the air suctioned through the suction unit, the dust separation unit comprising:
a first cyclone unit, wherein an axis of the suction motor extends along an axis of a cyclone flow of the first cyclone unit, and
a second cyclone unit configured to receive the air and the dust from the first cyclone unit and to separate the dust from the air received from the first cyclone unit, wherein the suction motor is positioned above an outlet of the second cyclone unit, wherein the cleaner has:
a first air passage that surrounds an outer circumference of the suction motor and is configured to guide the air discharged from the outlet of the second cyclone unit to rise and flow into the suction motor, and
a second air passage configured to discharge the air discharged from the suction motor to an outside of the cleaner through air exits, the air exits being positioned above the suction motor.
