iRobot is best known for its Roomba vacuum cleaner, an automated dustbuster for the domestically lazy. But as a Daily Show investigation reveals, it also makes millions on killing machines for the U.S. government.

Well, not killing machines so much as bomb-finding machines. Close enough! Watch the iRobot employee cringe, visibly, as Daily Show correspondent Samantha Bee goofs around with one. (One gets the sense that the iRobot executives who approved this headquarters tour are too intellectually refined to watch anything as base as television.) iRobot has a $286 million contract to provide PackBots to the U.S. Army for reconnaissance missions. Makes you wonder what those cuddly Roombas are capable of, doesn't it?
