We have heard a lot about vacuum cleaners, but what about the monotonous and boring wet-mopping of floor. What about the new iRobot Scooba 230 ($TBA) to handle all the dirty work for you. This is a 3.5-inch tall, 6.5-inch diameter helper and it uses a three-stage cleaning system to wash, scrub, and squeegee floors, cleaning up to 150 square feet of bathroom, kitchen, or entryway without you so much as lifting a finger.
