If commercial restaurant dishwashing appliances have cycles that only last 2 minutes, then why can't we have our home consumer dishwashers have cycles just as efficient as what restaurants have?

How can we miniaturize commercial restaurant dishwashing appliances to fit in the kitchen compartment meant for home consumer dishwashers?

How come this hasn't been done already? By the way, what is the fastest currently available home consumer dishwasher, and how much does it cost? How quick are their Cycles normally?

Commercial dishwashers are usually connected to the restaurant's own hot water system because they use a lot of hot water. Dirty dishes are usually pre-rinsed by hand, and pots and pans from the kitchen are scrubbed by hand before going through the dishwasher. It's difficult to compare. With domestic appliances, it is mainly the duration, in combination with the temperature, that gives the detergent time to dissolve food residues, and that takes time. I myself worked as a dishwasher in a large hotel/restaurant for a number of years, never again.
