If I purchase 'Laundry Day' will all of my sims be required to do laundry?

Once you place a washer and dryer, wash tub and/or clothes line your sims will start dropping their clothes when they change. If you have no clothes hampers or if the hampers are full, sims will drop their clothes on the floor. If you have lazy or slob sims they will drop their clothes on the floor no matter how many clothing hampers you have in the house. If you have a maid or butler (or a neat friend visiting) your sims won't have to wash at all. If you have neat sims they will do laundry without your prompting though.
