Control method for laundry treatment apparatus

A control method for a laundry treatment apparatus, where the laundry treatment apparatus includes a first reservoir for holding water and defining a first opening for introduction of laundry, a second reservoir placed inside the first reservoir, the second reservoir being rotatable about a rotation axis perpendicular to a bottom surface of the first reservoir and defining a second opening that is positioned under the first opening, a through-hole that is defined in the second reservoir, a spray unit for spraying water to an inside of the second reservoir, and a drain unit for draining water inside the first reservoir, includes rotating the second reservoir to thereby apply force on laundry received in the second reservoir, spraying water to the inside of the second reservoir via the spray unit, and discharging the sprayed water in the second reservoir to an outside of the first reservoir via the drain unit.
