A steamer may uniformly spray steam onto laundry even when a position of a user's arm changes. The steamer may include: a handle having a hinge formed at one end in a longitudinal direction thereof; a head that is rotatably connected to the hinge and sprays steam; a motor that rotates the head about the hinge; a sensor that senses an inclination in the longitudinal direction of the handle with respect to a horizontal line; and a controller that operates the motor, based on the inclination sensed by the sensor, to rotate the head to a position at which the head may spray steam horizontally.
