This is Roomba, the robotic vacuum that can be scheduled to navigate autonomously through your home up to seven times per week–a feature unique to the Hammacher Schlemmer model–to remove deeply imbedded dirt and dust from carpets and floors (Play Video.) The unit’s specially designed dual, counter-rotating agitator brushes spread carpet fibers and enable the powerful vacuum to remove pet hair and other stubborn detritus from low and high-pile carpets. Sensors redirect the unit when it encounters furniture, walls, or stairs, and its enhanced anti-tangle technology reverses the rotation of the brushes when it senses rug fringe. Two Virtual Wall lighthouses project infrared beams that confine the vacuum to one room until it is thoroughly cleaned and then allow it to move on to another room. Cleans up to four rooms per charge and automatically returns to its drive-on charger when its battery runs low. Includes two replacement filters and two replacement brushes. 3″ H x 13″ Diam. (11 3/4 lbs.)

This is Roomba, the robotic vacuum that courses autonomously through rooms and cleans floors and carpets using a powerful motor and proprietary brushes specially designed to remove deeply imbedded pet hair from carpets. The unit has dual, counter-rotating agitator brushes that spread carpet fibers and enable the vacuum to remove pet dander, kitty litter, and dust and dirt left behind by paws. The motor provides superior suction that captures pet dander from low- or high-pile carpets. A sensor redirects the unit before it encounters furniture, walls, or stairs, and it has an enhanced anti-tangle technology that enables the Roomba to reverse the rotation of its brushes when it senses rug fringe. Two Virtual Walls project infrared beams that confine the vacuum to one room, ensuring thoroughly cleaned floor surfaces. The robotic vacuum can clean up to three rooms per charge and automatically returns to its drive-on charger when its battery runs low. Includes a set of additional brushes and filters. Virtual Walls require two C batteries. 4 1/4″ H x 13 1/2″ Diam. (7 1/2 lbs.)

This is the advanced robotic sweeper with two heavy-duty brushes that rotate 1,000 times per minute to pick up woodchips, leaves, nuts, bolts, dirt, and more from indoor or outdoor surfaces. Ideal for use in garages and basements and on patios and decks, the unit navigates across surfaces autonomously, sweeping debris toward its high capacity dustbin that is 20% larger than previous models. Made by iRobot, a company founded by roboticists and renowned for its tactical robots used in U.S. military reconnaissance missions, the robotic sweeper has a sensor that redirects it before encountering workbenches, cars, stairs, or ledges. The device begins to clean at the touch of a button and its rugged rubber wheels and swiveling front caster enable optimal cleaning on concrete, wood, or tile floors. Includes AC charger. 3″ H x 13″ Diam. (6 1/2 lbs.)
