The Roomba Special Edition has it all and gets it all. Roomba Discovery SE is the top of the line Roomba with some very down to earth features. Like Roomba Discovery, the SE features Dirt Detect, the self-charging Home Base, an extra-large debris bin, the Roomba Remote, three cleaning modes. And, of course, the SE comes with the Advanced Power System that gives all Roombas the energy to get the job done. SE does it all, and looks great doing it.
