The bots that take orders in a Kintharian food stall are "dumb" AIs and don't even acknowledge things that aren't relevant to their work. Their responses are limited to stuff like "Hello, may I take your order", "Our daily special is [variable]", "That will be [variable] moneys", and of course, "I'm sorry, I didn't understand that".
Helian domestic robots on the other hand are capable of human levels of intelligence. You can actually hold a conversation with your Helian robot butlers and whatnot. Helian combat automata are equally intelligent, at least when it comes to tactics and risk assessment, but have a more limited vocabulary and a few essential rules of robotics ripped out. For very good reasons, Helians have not attempted to build machines capable of self-improvement.
tl;dr Kintharian robots are mindless drones, while Helian ones are actually intelligent.
