1. A robot cleaner comprising: a main body accommodating a suction motor configured to generate a suction force; a wheel configured to rotate to automatically move the main body along a floor; and a suction head configured to clean the floor based on the suction force when in communication with the suction motor, wherein the main body includes: a first connector to which the suction head is coupled; an accommodating recess provided at a front of the main body, wherein when the suction head is coupled to the first connector, a portion of the suction head is received in the accommodating recess such that a first part of the suction head vertically overlaps a portion of the main body, and a second part of the suction head protrudes from sides and front of the main body; a second connector to which a hose is selectively coupled, and a second suction passage which is in communication with the hose when coupled to the second connector, wherein the second connector includes a connection body to which the second suction passage is connected, wherein the connection body is movably connected to the main body such that the second connector is movable between a first position and a second position, wherein when the connection body is moved to the first position, the second connection passage is substantially received in the main body, and when the connection body is moved to the second position, at least a portion of the second connection passage protrudes from the main body, wherein when the connection body is moved to the first position, the main body prevents the second connector from being connected to the hose, and wherein when the connection body is moved to the second position, the second connector is positioned to be connectable to the hose.
