iRobot's Scooba is a household, robotic floor cleaner designed for hard floors made of materials such as tile and linoleum reports Cnet. It vacuums up loose particles and applies cleaner to soak up dirt, then dries the floor, which also makes it safe for wood.

"It is like an industrial floor cleaner, but for your home," said iRobot CEO Colin Angle. "Even if it wasn't a robot, this (makes mopping obsolete). With mopping, most of the time you are spreading dirty water around. But because it's a robot you push a button and it cleans your floor."
