PC Mag reviews the new iRobot Scooba floor washing robot. iRobot started to sell the Scooba early November. As far as I know the iRobot Scooba is only available through the iRobot store for $399.99.

Quote:
"iRobot's Scooba Floor Washing Robot, the follow-up to the hugely successful Roomba home vacuum, the Scooba sweeps, scrubs, mops, and even dries the floor.
It does all this with very little interaction from you: The Scooba's robot brain lets it map out your room, navigate obstacles, and know when it has cleaned the entire room. At $399.99 list, this is a smart, powerful, effective solution for cleaning tile floors, but selling it to the American public could be a more uphill battle than they faced with the Roomba floor vac.
