1. A cleaner comprising:
- a suction unit configured to guide air into the cleaner;
a dust separation unit comprising;
a first cyclone unit configured to separate dust from air that is suctioned into the cleaner through the suction unit; and
a second cyclone unit configured to receive air that is discharged from the first cyclone unit, the second cyclone unit comprising a plurality of cyclone bodies that are configured to separate dust from the air that is discharged from the first cyclone unit;
a suction motor configured to drive a rotation of a rotary impeller via an impeller shaft to generate a suction force that suctions air into the cleaner through the suction unit;
a motor housing that is configured to house the suction motor;
a pre-filter configured to be removable from the cleaner and that is configured to, in a state of being inserted into the cleaner, filter air that is discharged from the second cyclone unit and before the air flows into the motor housing and subsequently flows through the rotary impeller; and
an air exhaust that is configured to receive air that flowed through the rotary impeller and the suction motor and to discharge the air to an outside of the cleaner,wherein, in a state in which the cleaner is oriented with the impeller shaft elongated longitudinally along a vertical direction, a top of the second cyclone unit is disposed below a bottom of the suction motor, andwherein the pre-filter is configured, in the state of being inserted into the cleaner, to circumferentially surround at least a part of the motor housing and to discharge the filtered air in an inward direction toward the motor housing.

Abstract
A cleaner includes: a suction motor that generates suction force; a dust separation unit that separates dust from air sucked by the suction force; a motor housing that covers the suction motor; a flow guide that surrounds an outer side of the motor housing and guides air discharged from the dust separation unit to the suction motor; and a body that forms an external appearance by surrounding the flow guide and guides air discharged from the suction motor together with the flow guide.
