摘要： The present disclosure relates to a cleaner system of a cleaner. The cleaner system includes: a cleaner which includes a dust bin having one openable side thereof; and a cleaner station on which the cleaner is mounted. The cleaner includes: a first discharge cover which covers a portion of the open side of the dust bin; and a second discharge cover which covers the rest portion of the open side of the dust bin. The cleaner station includes a dust collection motor which generates a suction force sucking dust within the dust bin. Therefore, the suction force of the dust collection motor is concentrated by opening the second discharge cover first, so that adsorbed small dust is more easily sucked. Large dust is sucked by opening the first discharge cover after the small dust is sufficiently sucked, so that dust is efficiently discharged under the general power of the dust collection motor.
