With the Roomba i7+, another hassle associated with cleaning has been handled thanks to robotic developments. iRobot’s newest robot vacuum iteration actually empties itself while docked.

Another noteworthy change on the model: bristles have been replaced with rubber surfaces on the dual brush system. Learn more, and watch a feature announcement video, on Core77.
