Abstract: A laundry treating apparatus includes a tub configured to hold wash water, a drum rotatably supported in the tub and including a shaft disposed perpendicular with the ground, and a sub-drum detachably mounted to the drum and configured to wash laundry independently from the drum. The sub-drum includes a discharging area in which a discharging path is defined to selectively discharge the wash water in the sub-drum by a centrifugal force generated by rotation of the sub-drum. A check valve is included in the discharging area and is configured to selectively open and close the discharging area when acted on by an external force applied by the centrifugal force generated by the rotation of the sub-drum.

Abstract: Disclosed is a method for controlling a laundry treating apparatus that includes: a tub; a main drum rotatably disposed within the tub; a driver configured to drive the main drum; and an auxiliary drum disposed in the main drum configured to be attached to or be detached from the main drum. The method comprises a positioning operation for allowing a predetermined portion of the auxiliary drum to be positioned at a target position via a rotation of the auxiliary drum, wherein the positioning operation is configured such that when the predetermined portion reaches a braking-initiation position set such that the predetermined portion is positioned at the target position, a braking of the auxiliary drum is initiated, wherein the braking-initiation position is set to vary based on a magnitude of a load applied to the driver.
