Abstract: A method for controlling a laundry treating apparatus includes a dry cloth sensing operation of sensing an amount of clothes put into a drum, a wet cloth sensing operation of sensing a washing load based on a moisture content of the clothes by supplying water into a tub, and a cloth material sensing operation of sensing a cloth material of the clothes put into the drum based on a rpm gap and a motor-constrained state where rotation of a motor is restricted. The rpm gap is a difference between a target rpm of a rotator in the drum and an actual rpm of the rotator.
