Recovery device for recovering dust from dust collector

The present application comprises: a connection detection unit for detecting whether the vacuum cleaner is connected to the recovery device; a motor which rotationally drives the rotating blade part so as to generate a suction force for sucking dust in the dust collector; and a motor control unit that operates the motor on the basis of the connection detection unit detecting the connection between the cleaner and the recovery device, and stops the motor on the basis of the connection detection unit detecting the removal of the cleaner from the recovery device. The motor control part starts the motor under the condition that the time interval between the detection time when the connection detection part detects the connection between the vacuum cleaner and the recovery device and the work stop time when the motor is stopped before the detection time is larger than a specified interval threshold value. 本申请包括：连接检测部，检测吸尘器是否连接于回收装置；马达，转动驱动转动叶片部，从而产生用于抽吸吸尘器内的尘埃的抽吸力；马达控制部，基于连接检测部检测到吸尘器与回收装置的连接而使马达工作，并且基于连接检测部检测到吸尘器从
