iRobot Scooba

With iRobot's new Scooba cleaning process you can simultaneously prep, wash, scrub and dry hard floors, all at the touch of a button. Unlike a conventional mop that spreads dirty water on the floor, Scooba applies only fresh water and cleaning solution to the floor from a clean tank. Scooba can clean wet spills in addition to dirt and grime, and it is safe for use on all sealed, hard floor surfaces, including wood and tile. $399.99 www.irobot.com
