If competition breeds innovation, robot vacuums should be about ready to take over the world any day now. The latest automated vacuum cleaner is the Neato XV-11, a Roomba clone that claims superior weaponry in its mission to clean floors: lasers. The XV-11's Room Positioning System (seriously?) scans its path with lasers to map out your room and avoid any obstacles (as opposed to the Roomba, which lightly bumps obstacles before changing direction).
I honestly don't care so much about how my robot vacuum avoids obstacles — I'm more concerned about how long the charge lasts and, well, if it actually works. We'll give Neato the benefit of the doubt until the XV-11 goes on sale in February. When it does, you'll have to shell out $400 for its laser-guided suction.
