Having worked on and off in restaurants over the years, you have to clean these things nightly - and thoroughly - or else they get disgusting very quickly. That's the biggest problem with most of this kind of thing, espresso machines too. We have a single-serve automatic coffee maker right now that's not supposed to require regular cleaning, it's a little better about it but it can still get really gross.
