If they're automatically reporting via API to the online store, so the author can check the status in his script, they're all the same model with auto-sanitize. The old manual clean models always report online, then the customer gets rejected and refunded when they actually go pick up their order, as mentioned elsewhere in the thread about some NYC locations. Nice try, but you know, burden of proof on the accuser and whatnot.
That adds doubt on one possibility (though I don't know if those devices are reporting their up/down status via a voltage checker for manual cleaning units), but there are other possibilities.
