When it comes to easing robots into mainstream consumer markets, nobody is doing better than iRobot (NASDAQ:IRBT). The company has pumped more funds into its advertising during the past year, which means catchy ads for its Roomba floor cleaner are sweeping (no pun intended) television and the Internet.

But iRobot is so much more than just robotic household appliances. This company has helped the U.S. government in a big way, and is venturing into the world of health care, all while keeping some pretty solid financials. Even after spending $14 million on Roomba advertising last year, iRobot has still managed to maintain a 5% operating margin.  In the video below, Motley Fool contributor Caroline Bennett takes a closer look at why iRobot might be a good bet to take your portfolio into the future.
