 the connection module comprises a second coupling part to be coupled to the first coupling part, and   the second coupling part comprises a first groove, in which the first coupling part is accommodated, and a second groove extending from the first groove in a direction crossing a direction in which the first coupling part is accommodated in the first groove so that coupling of the first coupling part and the second coupling part is completed by a rotation operation of the connection module.   
     
     
         12 . The cleaner of  claim 11 , further comprising a sealing member configured to prevent the air from leaking between the connection module and the discharge guide. 
     
     
         13 . The cleaner of  claim 12 , wherein a sealing member coupling part, on which the sealing member is installed, is provided on the discharge guide,
 the connection module comprises a cover part configured to cover the second cyclone unit and a connection part which extends from the cover part and on which the second coupling part is provided, and   the sealing member contacts the cover part.   
     
     
         14 . The cleaner of  claim 11 , wherein, when the first coupling part is disposed at a position, at which the first coupling part is aligned with the second groove, in the first groove, the sealing member is pressed, and the first coupling part is accommodated in the second groove by the rotation operation of the connection module in the state in which the sealing member is pressed. 
     
     
         15 . The cleaner of  claim 10 , wherein the dust separation module further comprises a storage unit coupled to the second cyclone unit and configured to store the dusts separated in the second cyclone unit. 
     
     
         16 . The cleaner of  claim 15 , wherein the filter unit has an upper end contacting the connection module and a lower end seated on the storage unit. 
     
     
         17 . A cleaner comprising:
