There are two types of washing machines, top-loading and front-loading. Top-loading washers are the conventional type washing machines where the tub is filled with water, and an agitator is used to clean the clothes. These generally work very well, and are great for their value. Front-loading washing machines, though a little pricier, perform better. Front loaders do not have agitators, but instead use tumbling as a method of cleaning clothes. Because an agitator is not used, front-loaders are gentler on fabrics and use less water.
