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.

Claim (Index 16):
A cleaner comprising:\n a suction unit configured to guide air into the cleaner; a dust separation unit comprising:\n a first cyclone unit configured to separate dust from air that is suctioned into the cleaner through the suction unit; and \n a second cyclone unit configured to separate dust from air that is discharged from the first cyclone unit; \n 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 cleaner body that is configured to accommodate the motor housing, and that has a first opening that provides access to an interior of the cleaner; a filter system that is configured to be detachably coupled to the cleaner body at the first opening of the cleaner body, the filter system comprising:\n a first filter that is configured to filter air that is discharged from the second cyclone unit and before the air enters the motor housing and subsequently flows through the rotary impeller; and \n a second filter that is configured to filter air that has flowed through the first filter, the rotary impeller, and the suction motor, and that is discharged from the motor housing before the air exits the cleaner body, \n wherein in a state in which the filter system is coupled to the cleaner body and the cleaner is oriented with the impeller shaft arranged longitudinally along a vertical direction, the second filter is disposed above the first filter and applies pressure in a downward direction that maintains the first filter inserted in the cleaner body.
