You probably wouldn't want a commercial dishwasher at home. You must first thoroughly rinse all food particles off all items (think human dishwasher in a resturant). Then it uses the hot water it used to sterize the previous load as wash water for the next. As soon as one load completes, it will immediately expect another, as they are designed for continuous heavy use. They are very loud, require a 240V or 3 phase connection, and release truly massive amounts of steam requiring a hood/extractor to not mess up a residential kitchen. For a family of 4 people washing everything by hand would probably be less work and cheaper.
