The present invention provides a dry cleaning system, comprising a dry cleaning machine, the dry cleaning machine comprising a dry cleaning drum; a vacuum-pumping device, the vacuum-pumping device being able to be in fluid communication with the dry cleaning drum; a vacuum degree sensor and/or an oxygen content detector; and a control means, the control means being configured to be able to communicate with the vacuum degree sensor and/or the oxygen content detector. The vacuum-pumping device can be actuated to establish and maintain a negative pressure within the dry cleaning machine, and the control means is configured to actuate the dry cleaning machine when the vacuum degree and/or the oxygen content detected by the vacuum degree sensor and/or the oxygen content detector are below preset values, so as to start at least one operation on an object. Use of the dry cleaning system can improve the dry cleaning efficiency, particularly, the safety of the dry cleaning process, and further exert the detersive power of a solvent.
