So it looks like Hobart has created an add on for its under counter machines that basically use the old Maytag Reverse logic of plates on top and glasses on bottom. Of course there’s no center tower to spray up so one would need to follow the logic for this to work. It’s not a bad idea but you would definitely want to train your operators on how to use it.
The last hotel I worked at used real dishes for the breakfast and had a Jackson undercounted dishwasher. The breakfast people would shovel that poor thing full until the door wouldn’t close, there was no way water the water could get to half the load but they never thought about that. I’m sure that would be a two fold problem with this two rack design that requires a specific loading configuration.
Some of these commercial units are pretty interesting now in the way they straddle the line between consumer and commercial. I installed a couple Miele PG 8056U units, and they almost feel like an evolution of a Hobart-style KitchenAid. Commercial guts but with pull out baskets and aggressive 6 minute cleaning cycles but still very quiet, not much steam, and pump out to a trap arm. You could pretty much install one in any kitchen opening, if you had a 240v circuit and 3/4" GHT hot and cold lines. And $6000 to spend.

The linked document shows a pan and bowls in the lower rack that surely are blocking lower spray up to the second rack. Is there a top/down spray arm for it?
Yes these have a full size arm on the top and the bottom. But that’s where the reverse rack logic comes into play, you would have to load the top rack in the way that all items can be cleaned from the top down by the wash arm on the roof of the machine.
