Abstract: A discharge apparatus of a vacuum cleaner, which does not allow a sealing to break due to a discharge force, and a vacuum cleaner having the same, are provided. The discharge apparatus includes a motor to generate a discharge force, a discharge filter unit to filter discharged air, a housing to support the motor, and comprising a filter accommodating unit integrally foxed thereon to receive the discharge filter unit therein, and a sealing member to seal a space defined between the discharge filter unit and the filter accommodating unit.

Abstract: An apparatus for fabricating a bellows type hose and a fabricating method thereof, which can improve a bellows type hose for use in a vacuum cleaner or the like in quality. The apparatus includes a power generating unit, an outer mold having at least one folds-forming gear disposed to rotate while revolving around a hollow-cylindrical basic material conveyed from an injection molding unit and thus to form folds on the hollow-cylindrical basic material, the at least one folds-forming gear having a waved folds-forming part formed on an outer circumferential surface thereof, and a power transmitting unit to transmit a power of the power generating unit to the at least one folds-forming gear of the outer mold.

Abstract: A robot cleaner for cleaning ambient air in a cleaning area while cleaning a cleaning surface, and a system thereof. The robot cleaner and the system thereof comprise a body, a driving part driving a plurality of wheels disposed at a lower portion of the body, a dust suction part formed in the body to draw-in dust from a cleaning surface, and an air cleaning part formed in the body to draw-in dust-ladened air from a cleaning area. The robot cleaner cleans the air and discharges cleaned air, and, utilizing a controller disposed in the body, controls the driving part and the air cleaning part. Accordingly, since the robot cleaner provides cleaned and fresh air to a predetermined cleaning area while cleaning a surface, it contributes to a fresher residential environment.
