Since the beginning, iRobot has set the bar for robot vacuums and continues to make each generation more innovative than the last. The newest addition, the Roomba j7+, boasts a number of enhancements including quieter operation, greater suction power, the ability to spot clean messes, improved custom room mapping, and cleaning time estimates, to name just a few. But most notably, the Roomba j7+ also gets PrecisionVision Navigation, which recognizes objects and avoids obstacles such as charging cords. It can even detect solid waste from pets, preventing an embarrassing mess. The j7+ also has a self-emptying bin, so you can forget about vacuuming for months at a time. Available now, the iRobot Roomba j7+ Robot Vacuum is priced at $849.
