Good luck with the Scooba!
I was going to suggest the Roomba because I'm in nearly exactly the same environment: 1,200 sq ft, all hard surfaces, use (white) socks as slippers, and share the apartment with a furry demon named Juno.
Nice thing about the 9XX and newer robots is that they'll clean the entire apartment in one pass. Even if the robot can't completely vacuum the apartment in one pass, it will return to the Home Base by itself, charge, and resume the job exactly where it left off automatically!
I vacuum the main traffic areas every other day on a single pass and the whole apartment on the weekends with a double-pass.
Of course the one difference in my environment is the lack of textured tile, so that could tilt the balance in favor of Scooba, but so far - on my smooth surfaces - my socks easily pass the "Clean Floor?" test.
Oh, and about those BB&B coupons? They apply to on-line orders.
