         2 . The cleaner of  claim 1 , further comprising:
 an extension tube configured to connect the cleaning module and the cleaner main body,   wherein the auxiliary battery housing is disposed between the extension tube and the cleaning module.   
     
     
         3 . The cleaner of  claim 2 , wherein in a state in which the auxiliary battery is coupled to the auxiliary battery housing and the extension tube and the cleaning module are coupled, the auxiliary battery is disposed to be farther from the floor than is a portion where the extension tube and the cleaning module are in contact with each other. 
     
     
         4 . The cleaner of  claim 2 , wherein when the cleaning module cleans the floor surface in a state in which the auxiliary battery is coupled to the auxiliary battery housing and the extension tube and the cleaning module are coupled, at least a part of the auxiliary battery is disposed to be closer to the floor surface than is the extension tube. 
     
     
         5 . The cleaner of  claim 2 , wherein the auxiliary battery is inclined downward and inserted into and coupled to the auxiliary battery housing. 
     
     
         6 . The cleaner of  claim 5 , wherein a direction in which the auxiliary battery is inserted has an angle of 0 degrees or more and less than 90 degrees with respect to a longitudinal direction of the extension tube. 
     
     
         7 . The cleaner of  claim 2 , wherein the cleaning module comprises a connection tube to which the extension tube and the auxiliary battery housing are coupled, and
 wherein an upper end of the auxiliary battery is disposed to be farther from the floor surface than is an upper end of the connection tube in a state in which the auxiliary battery is coupled to the auxiliary battery housing and the auxiliary battery housing is coupled to the connection tube.   
     
     
         8 . The cleaner of  claim 2 , wherein the cleaning module comprises a connection tube to which the extension tube and the auxiliary battery housing are coupled, and
 wherein a lower end of the auxiliary battery is disposed to be closer to the floor surface than is a lower end of the connection tube in a state in which the auxiliary battery is coupled to the auxiliary battery housing and the auxiliary battery housing is coupled to the connection tube.   
     
     
         9 . The cleaner of  claim 1 , wherein the auxiliary battery is connected in series to the battery. 
     
     
         10 . The cleaner of  claim 1 , wherein the auxiliary battery is connected in parallel to the battery. 
     
     
         11 . The cleaner of  claim 1 , wherein the auxiliary battery is connected selectively in series or in parallel to the battery. 
     
     
         12 . The cleaner of  claim 1 , wherein the cleaning module comprises:
 at least one mop configured to wipe the floor surface; and   a mop driving motor configured to provide a rotational force to the mop.   
     
     
         13 . The cleaner of  claim 12 , wherein the cleaning module comprises:
 a water tank configured to store water; and   a diffuser configured to discharge moisture, which is supplied from the water tank, to the mop.   
     
     
         14 . The cleaner of  claim 13 , wherein the cleaning module further comprises a steam generator configured to heat water introduced from the water tank and supply the heated water to the diffuser. 
     
     
         15 . The cleaner of  claim 14 , wherein the auxiliary battery supplies power to the steam generator. 
     
     
         16 . A cleaner comprising:
 a cleaning module configured to eliminate debris on a floor surface;   a cleaner main body comprising a battery configured to supply power to the cleaning module, and a handle configured to be grasped by a user;   an auxiliary battery configured to supply power to the cleaner main body or the cleaning module; and   an auxiliary battery housing to which the auxiliary battery is detachably coupled,   wherein the cleaner main body comprises a battery housing configured to accommodate the battery, and   wherein the auxiliary battery housing is detachably coupled to the battery housing.   
     
     
         17 . A cleaner comprising:
 a cleaning module configured to eliminate debris on a floor surface;   a cleaner main body comprising a battery configured to supply power to the cleaning module, and a handle configured to be grasped by a user;   an auxiliary battery configured to supply power to the cleaner main body or the cleaning module;   an extension tube configured to connect the cleaning module and the cleaner main body; and   an auxiliary battery housing detachably coupled to the extension tube and configured such that the auxiliary battery is detachably coupled to the auxiliary battery housing.
