Just picked up the new Scooba 390. Nice color changes occurred on most of the body and components. Even with the color changes the parts are still interchangeable with parts off of my 5900s and the later 5800. Although I don't own the earlier 3XX models I suspect that most of the parts are also similar.
I specialize in 5900 and 5800 repair. If you want to keep your older but great Scooba running again just use the "Contact Me" page to send me your message about your Scooba and what you need.
