"According to iRobot, "world-class roboticists created Roomba" and then "experts tested it." We take this to mean that the Roomba will almost certainly not massacre your entire family in a death orgy of inscrutable machine rage, but we regret that we cannot offer refunds in the event that it does. Hey, if you want a plantation full of robot slaves, you have to accept the risk of a bloody uprising."
