What Are the Differences Between a Steam Washer and a Regular Washer?

Home appliance manufacturer LG explains that a steam washer is different from a regular washer in that it is more expensive, uses less water and is gentler on delicate fabrics. These front-loading machines lack the fabric-damaging agitators found in conventional top-loading appliances. Steam washers also sterilize clothing, a feature lacking on many standard washers. Steam sterilization kills viruses and bacteria without traumatizing clothing fibers with jets of hot, pressurized water.
