    摘要: A washing machine and a control method thereof are disclosed. The washing machine has a plurality of washing tubs to clean laundry in different ways classified according to capacity and types of clothing. Different washing tubs simultaneously stop operations or are stopped at different times spaced apart from each other by a predetermined time, although washing tubs have different washing conditions (e.g., different input times of laundry, different amounts of laundry, different washing courses, etc.) when laundry is cleaned using the washing tubs.
