         11 . A cleaner comprising:
 a housing having a hollow cylinder shape;   a barrier for dividing an inner space of the housing into an upper space and a lower space;   a barrier through-hole provided to pass through the barrier such that the upper space and the lower space are communicated with each other;   an intake unit provided on a circumferential surface of the housing to communicate the lower space with the outside of the housing;   a housing through-hole to communicate the upper space with the outside of the housing;   an upper cover provided in the housing to open or close the housing through-hole;   an exhaust unit provided to pass through the upper cover to discharge the air inside the upper space to the outside of the housing;   a fan comprising a case provided in the upper space, a case intake port provided on one surface of the case headed for the barrier through-hole to allow the air to enter the case, a case exhaust port provided on one surface of the case headed for the exhaust unit to discharge the air inside the case, and an impeller rotatably provided inside the case; and   a particle separator provided in the lower space, providing a path that guides the air entering the intake unit to the barrier through-hole and separate particles from the air by a centrifugal force.   
     
     
         12 . The cleaner of  claim 11 , further comprising a first filter located between the barrier through-hole and the case intake port to filter the air. 
     
     
         13 . The cleaner of  claim 12 , further comprising a second filter located between the case exhaust port and the exhaust unit to filter the air. 
     
     
         14 . The cleaner of  claim 11 , further comprising a handle provided on the circumferential surface of the housing at a point symmetrical to a point in which the intake unit is located, and
 wherein the handle is provided along the height direction of the housing, and the exhaust unit is configured to exhaust air along the height direction of the housing.   
     
     
         15 . The cleaner of  claim 14 , wherein the housing through-hole is configured to pass through an upper surface of the housing, and the upper cover is configured to form the upper surface of the housing. 
     
     
         16 . The cleaner of  claim 15 , wherein the exhaust unit comprises a plurality of holes passing through the upper cover, and the holes are configured to form a ring surrounding a center of the upper cover. 
     
     
         17 . The cleaner of  claim 14 , further comprising:
 a battery housing provided on the circumferential surface of the housing at a point symmetrical to a point in which the intake unit is located; and   a battery detachably provided in the battery housing,   wherein the handle is configured to connect the circumferential surface of the housing with the battery housing.   
     
     
         18 . The cleaner of  claim 11 , wherein the particle separator comprises:
 chamber bodies provided in a hollow cylinder shape and dividing the lower space into a first chamber communicated with the intake unit and a second chamber communicated with the barrier through-hole;   a body barrier dividing the second chamber into a first space communicated with the barrier through-hole and a second space not communicated with the barrier through-hole;   a communication hole provided to pass through the chamber bodies, communicating the first space with the first chamber;   a path body provided as a pipe surrounding the barrier through-hole, having one end fixed to the barrier and the other end located in the second space by passing through the body barrier;   a discharge pipe provided as a pipe extended from the barrier through-hole toward the body barrier and located inside the path body;   an inlet provided to pass through the path body, guiding the air inside the second chamber to the inside of the path body; and   an air flow forming portion provided between the discharge pipe and the path body in a screw shape, rotating the air entering the inlet, inside the path body   
     
     
         19 . The cleaner of  claim 18 , further comprising:
 a housing outlet communicated with the lower space by passing through a bottom surface of the housing; and   a cover detachably provided in the housing, closing the housing outlet.   
     
     
         20 . The cleaner of  claim 19 , further comprising:
 a storage unit detachably provided in the housing to be replaced with the cover, expanding a volume of the lower space when coupled to the housing.
