Disclosed is a method for controlling a laundry treating apparatus, wherein the laundry treating apparatus includes: a drum having a laundry storage space defined therein; a duct defining a channel for supplying air discharged from the drum back to the drum; a fan to move air along the duct; a heat-absorber for removing moisture from air introduced into the duct; a heat-emitter disposed inside the duct to heat air passing through the heat-absorber; a water collector for storing therein water discharged from air passing through the heat-absorber; a first filter for filtering air flowing from the drum to the duct; a second filter positioned between the first filter and the heat-absorber and filtering air passing through the first filter; a water discharger having a water storage space defined therein; a water discharger supply pipe for supplying water stored in the water collector to the water discharger; a water ejector for ejecting water into at least one of the second filter or the heat-absorber; a water ejector supply pipe for supplying water stored in the water collector to the water ejector; a water supply pipe constructed to connect the water discharger and the water collector to each other; a water supply valve for controlling opening and closing of the water supply pipe.

A laundry treating apparatus includes a tub for holding 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 an inner circumferential surface of the drum. The sub-drum is configured to wash laundry independently from the drum. A discharging area of the sub-drum includes an inlet hole configured to draw wash water into the sub-drum, an outlet hole formed in a lateral wall of the sub-drum and configured to discharge the wash water outside the sub-drum, and a filter unit disposed under the discharging area and configured to filter wash water drawn into the sub-drum by rotation of the sub-drum.

A laundry appliance includes a tub positioned within an outer cabinet. A drum is rotationally operable within the tub. A fluid pump directs a process fluid through a fluid path that includes the tub. A fine-particle filter is positioned within the fluid path. The fine-particle filter separates microfibers from the process fluid to define captured microfibers.

A pet hair removal assembly for a laundry appliance includes a frame having a central support and legs. A cylindrical member is operably coupled to the central support of the frame. The cylindrical member defines recesses within an outer surface of the cylindrical member. A foreign substrate collection member is operably coupled to the cylindrical member. A fastener is positioned proximate each recess that operably couples the foreign substrate collection member with the cylindrical member.
