Dyson Secretly Creating Robot Vacuum

iRobot's Roomba is about to get a little competition from the folks at Dyson. Rumor has it that Dyson is recruiting roboticists who can help create a robotic vacuum with autopilot and mapping capabilities, the latter feature being something the Roomba lacks (it relies on bump sensors for direction).

So does this mean there's a more sophisticated robotic vacuum lurking around the corner? Could be, though I'm still waiting for the day we have robot maids.
