iRobot's best vacuum yet, but too pricey for most

It's 2015 and I'm still waiting for Rosie the Robot, or some sort of equivalent home bot, to clean my home. We're probably years away from a Jetsons-like future, but it's easy to forget that iRobot's Roomba has already been around for over 13 years now, steadily getting better at doing your dirty work. Now with the new Roomba 980, iRobot is making its vacuum-cleaning bot smarter than ever before -- so much so that it's calling the 980 the most important Roomba since it first debuted in 2002. It has a camera and advanced localization technology that allows it to see obstacles and map your floors, and for the first time, it's also wirelessly connected and works together with a mobile app. Most importantly, it finally rid my carpets of cat hair. The 980 is the best Roomba yet, plain and simple. Unfortunately, its high cost of $900 puts it out of reach for most people.
