A system attachable to a refrigeration circuit includes a recovery pump attachable to the refrigeration circuit to remove refrigerant. The recovery pump includes a pump, an electric motor, a battery pack, and a recovery pump controller for controlling the operation of the electric motor. The recovery pump controller has a first communication interface. The system further includes an accessory attachable to the refrigeration circuit concurrently with the recovery pump. The accessory includes a sensor for detecting a characteristic value of the refrigeration circuit, and an accessory controller electrically connected with the sensor to receive a signal corresponding with the characteristic value of the refrigeration circuit. The accessory controller has a second communication interface to communicate the signal to the recovery pump controller via the first and second wireless interfaces. The recovery pump controller controls the operation of the electric motor based upon the signal received from the accessory.
