The iRobot Roomba 880 Vacuum Cleaning Robot is very well designed for desirability.  Like all successful new products these days, the Roomba is well manufactured, simple-looking, and fresh.  Not to mention, a clean look to it (which is very important as a vacuum).  The Roomba is a one time investment vacuum machine.  It is autonomous and operates on its own so the consumer will never have to bother with manually and physically vacuuming again.  The technology inside is smart, while the outside is sophisticated and cool.  The Roomba is everything you would want in a vacuum with the added bonus of never having to manually vacuum again, and having a cool new robot in your home!
