         2 . The cleaner of  claim 1 , wherein the cleaning module comprises a bearing holder disposed radially outward of the first bearing and having one side coupled to the first bearing, and the other side coupled to the agitator, the bearing holder being configured to rotate together with the agitator. 
     
     
         3 . The cleaner of  claim 2 , wherein the bearing holder surrounds at least a part of an outer peripheral surface of the first bearing. 
     
     
         4 . The cleaner of  claim 2 , wherein the cleaning module comprises a gasket having an inner surface tightly attached to the bearing holder, and an outer surface tightly attached to the agitator. 
     
     
         5 . The cleaner of  claim 2 , wherein the cleaning module comprises a holder cover disposed radially outward of the bearing holder, configured to surround at least a part of the bearing holder, and having one side coupled to the bearing holder, and the other side coupled to the agitator. 
     
     
         6 . The cleaner of  claim 5 , wherein the holder cover comprises a stepped portion formed on an inner peripheral surface thereof and tightly attached to an end of the bearing holder. 
     
     
         7 . The cleaner of  claim 5 , wherein the bearing holder comprises a bearing holder coupling hook protruding from an outer peripheral surface toward the holder cover, and
 wherein the holder cover comprises a bearing holder coupling hole into which at least a part of the bearing holder coupling hook is inserted and caught.   
     
     
         8 . The cleaner of  claim 5 , wherein the agitator comprises an agitator guide coupling protrusion protruding toward the holder cover, and
 wherein the holder cover comprises an agitator guide coupling groove into which at least a part of the agitator guide coupling protrusion is inserted and caught.   
     
     
         9 . The cleaner of  claim 1 , wherein the agitator comprises:
 an agitator bar having therein a space and extending along the rotary shaft; and   an agitator guide disposed on the rotary shaft and coupled to an end of the agitator bar.   
     
     
         10 . The cleaner of  claim 9 , wherein the agitator guide has one side coupled to the agitator bar, and the other side coupled to the first bearing. 
     
     
         11 . The cleaner of  claim 9 , wherein the cleaning module comprises a pulley disposed in the housing, at least partially inserted into the agitator guide, and configured to transmit power to the agitator guide. 
     
     
         12 . The cleaner of  claim 11 , wherein the cleaning module comprises:
 a second shaft disposed in the housing and extending toward the inside of the agitator along the rotary shaft of the agitator; and   a second bearing at least partially inserted into the pulley and configured to connect the housing and the second shaft.   
     
     
         13 . A cleaner comprising:
 a cleaning module configured to suck outside air; and   a main body configured to provide a suction force to the cleaning module,   wherein the cleaning module comprises:   a housing coupled to the main body and having one side including an opening portion configured to allow an external space and an internal space to communicate with each other;   an agitator inserted into the opening portion and rotatably coupled to the housing; and   an end cap assembly configured to cover at least a part of the opening portion, separably coupled to the housing, and configured to be separated together with the agitator when separated from the housing.   
     
     
         14 . The cleaner of  claim 13 , wherein the end cap assembly is at least partially inserted into the agitator and supports an inner peripheral surface of the agitator. 
     
     
         15 . The cleaner of  claim 13 , wherein the end cap assembly comprises a first bearing disposed inside the agitator. 
     
     
         16 . The cleaner of  claim 13 , wherein the end cap assembly comprises:
 an end cap configured to cover the opening portion and separably coupled to the housing;   a first shaft coupled to the end cap and extending toward the inside of the agitator along a rotary shaft of the agitator;   a first bearing at least partially disposed inside the agitator and coupled to the first shaft;   a bearing holder configured to surround at least a part of the first bearing; and   a holder cover configured to surround at least a part of the bearing holder and having one side coupled to the bearing holder, and the other side coupled to the agitator.
