iRobot Roomba 570 Autonomous Robotic Vacuum

This is the robotic vacuum that can be scheduled to navigate autonomously through your home up to seven times per week. The unit's specially designed dual, counter-rotating agitator brushes spread carpet fibers and enable the vacuum to remove hair and other detritus from low- and high-pile carpets. Sensors redirect the unit when it encounters furniture, walls, or stairs, and its anti-tangle technology reverses the rotation of the brushes when it encounters rug fringe. A remote control allows you to send the vacuum on an impromptu spot cleaning–a feature unique to the Hammacher Schlemmer model. Two virtual wall lighthouses project infrared beams that confine the vacuum to one room and allow it to move on to another room only when it has cleaned the entire surface. It cleans up to four rooms per charge and automatically returns to its drive-on charger when its battery runs low. Includes one replacement filter and two replacement brushes. Remote control requires two AA batteries and lighthouses require two C batteries. 2 1/2" H x 13" Diam. (11 3/4 lbs.) Advanced Features: * Automatically returns to its compact, self-charging Home Base to dock and recharge between cleanings * Remote Control allows you to steer and control Roomba from across the room. * Virtual Wall® Lighthouses (2) confine Roomba to one room until the entire floor is vacuumed before Roomba moves on to the next room. * Schedule up to seven cleaning days per week for Roomba to clean when it's most convenient for you * Faster counter-rotating brushes with improved design pick up more hair, debris and dust and are easy to remove and clean. * Improved filter captures more dust and allergens while a larger bin holds more debris * Improved anti-tangle technology keeps Roomba from getting stuck on cords, carpet fringe and tassels * Improved side brush makes Roomba even more efficient at cleaning edges and corners * 1 Replacement Beater Brush * 1 Replacement Bristle Brush * 1 Extra Filter
