I didn't even know that the Dolphin iO was in the works. I think I'll limp this Doheny Discovery (S200) along until it dies and then start the Doheny iO owners thread when I get my new cleaner!!! I never thought when I took the plunge 3 years ago with my current robot and decided to make a post about it, that I would still be talking about it in post #1701.
