I own a Roomba, and personally, now that I have one, I can't quite see the need for any other pets (my Roomba is notably more affectionate than many cats I have known, for example.) But apparently I'm in a minority, because the iRobot corporation has developed an addition to the Roomba line specifically designed for pet owners, and their never-ending battle against shedded fur. The new model comes with a large capacity bin to handle the extra debris that arises when someone insists on having organic lifeforms as their domestic companions, and the design of the sweeper system has been tweaked so that all that hair doesn't get tangled up around the brushes.
