Abstract

A laundry treating apparatus includes a cabinet with first and second cabinet doors. A first washing apparatus processes laundry that is placed through the first cabinet door at the front. A second washing apparatus processes laundry that is placed through the second cabinet door at the top. The second washing apparatus includes: a tub that holds water and has an opening at a top that is accessible through the second opening of the cabinet; a tub cover that covers the top of the tub and defines an inlet through which the tub is accessible; a tub door on the tub cover that opens or closes the inlet of the tub cover separately from the second cabinet door opening or closing the second opening; a drum inside the tub configured to rotate about a vertical shaft; and a first sensor that generates a signal based on the tub door being open.
