Oh, if it rains/snows then yeah you hang them inside on these typically, and you put something underneath so that they don't drip on the floor, or maybe you put them on the radiator or something like that. But if it's just cold and it's not raining then they still dry fine, it may just take a longer time. Most modern washers have a mode where they will partially dry them for you so you can hang them without them dripping on your floor.
