All professional dishwashers I have encountered (there may be others, obviously) require thorough rinsing (either high-pressure handheld wand or a wipe with a brush/cloth) so they are essentially "clean" before going in the dishwasher.

The dishwasher sanitizes the dishes via very hot water and thorough coverage, but does not really clean anything. It has high temperatures and high throughput - 5 minute cycles. Basically a completely different use case and probably unsuitable for a home.
