Trilobite vacuums your carpets with 90 watts of serious cleaning power. It takes just 40 minutes to clean a 14' x 15' room time you can spend cooking dinner, enjoying a program, or just relaxing. Its highly specialized infrared and ultrasonic sensors are so sophisticated, the vacuum will not fall down stairs or bump furniture or walls it wont even tip over a wine glass sitting on the floor. Trilobite maps the room perimeter, so it knows exactly the time it takes to complete maximum cleaning with optimal battery efficiency. When its finished, or the battery runs low, Trilobite automatically returns to its floor recharging station in the same room to rejuvenate its batteries. Two hour charge time. Three versatile vacuum modes: normal plots the room and vacuums all open surfaces, quick vacuums without room mapping, and spot concentrates on a 10' sq. area. Comes with two 6 1/2' long magnetic strips that can be set on the floor or hidden under carpet (permanently or temporarily) to block off Trilobites cleaning area.
