~17 years old or so. Notorious for collecting water where the mechanics innerds are. The key is to take it down every month or so, remove the cleaner bottle, and hit it with air. Let it dry. Also, don’t drop it! I can’t believe no other machine like this has been released. Refill the jug with what you think will work. Opinions differ. Most say vinegar and a plop of dish liquid as a surfactant but that may be counter intuitive. I use dollar tree daily shower spray. Good enough.
