Abstract: A suction port assembly of a vacuum cleaner. The suction port assembly has a pair of suction paths formed at a front and a rear portions of a bottom of a suction port body, respectively, so as to enhance the cleaning efficiency, and due to a presence of an elastic member formed at a front edge of the suction port body as shock-buffer, the reduction of the durability incurred by the collision with an external obstacle is prevented. Meanwhile, in case that a floorcloth is rotatably disposed on a lower surface of the bottom of the suction port body, since the suction port assembly further includes a floorcloth cover protruding from the bottom of the suction port body toward a cleaning surface, the safety of a user is guaranteed.

The discharge line tube of the compressor has a bent portion to reduce vibration and noise when the compressed refrigerant is discharged into a discharge pipe. The compressor includes an elastic member having hooks formed on both ends thereof, for generating a predetermined tension while being supported on the bent portion of the discharge line tube on two locations. Since vibration and noise can be reduced significantly, appliances that require the compressor as an essential element can provide optimum environment to users.
