In December 2009, a very quiet Silicon Valley startup called Neato Robotics announced the official release of the XV-11, a robotic vacuum cleaner. Priced at $399 and officially for sale in February, the XV-11 is clearly positioned to bite off a chunk of the iRobot Roomba's marketshare.
The biggest difference between Neato's XV-11 and the Roomba is that the XV-11 actually maps the room it's cleaning using SLAM. To achieve accurate SLAM, XV-11 has an onboard laser rangefinder to map of its surroundings
