Abstract: Provided is a high-efficiency slim vacuum inhalation apparatus which cools heat generated from heat-generation sources without using particular heat radiation components, and a robot cleaner employing the same. The vacuum inhalation apparatus does not need particular heat radiation components since an impeller is closely adhered to a rotational shaft by a pair of washers and an impeller bushing, to thus avoid from sliding, and since an inhalation efficiency which is caused by a brushless direct-current (BLDC) motor increases, and thus power consumption decreases. Further, since a BLDC motor is incorporated in a vacuum inhalation apparatus so that the vacuum inhalation apparatus can be implemented into a slim type, a robot cleaner can be also compactly realized into a slim type.
