Industrial dishwasher use much stronger detergent. So at home often have paintings, drawings or golden things on the dishes. With an industrial dishwasher such things would be a short joy.

Also you need much more electricity, because you need to make a lot of hot water in a very short time.

I think just the thermal cycling of an industrial dishwasher would damage consumer dishes in just a few cycles, if they even survive the first.
