Abstract: A method controls a washing machine including a drum rotatably provided in a tub that receives water, at least one nozzle spraying water into the drum, a washing motor rotating the drum, and a circulation pump circulating water within the washing machine. The method includes: controlling a rotation of the drum by operating the washing motor to rotate the drum at a first rotation speed in a first rotation direction, and to maintain a rotation of the drum at the first rotation speed in the first rotation direction so that laundry in the drum maintains contact with an inner circumferential surface of the drum; and controlling a pump speed of the circulation pump by operating a circulation pump motor in the circulation pump to accelerate and decelerate at least once while the washing motor rotates the drum at the first rotation speed in the first rotation direction.

Abstract: A laundry treating apparatus includes a cabinet, a tub provided inside the cabinet, a drum rotatably provided inside the tub to accommodate laundry, a motor directly connected to a rotation shaft of the drum, and a controller configured to control the driving of the motor according to any one of a plurality of preset drum driving motions. The controller controls the rotation of the motor to receive a physical force greater than a static frictional force acting between the laundry and the drum from an inner surface of the drum during a process in which the laundry falls to be in contact with a portion of the drum when a first motion of the plurality of drum driving motions is selected.
