iRobot Roomba j7/j7+ vs Roborock S8+/S8

The Roborock S8 is better than the iRobot Roomba j7. Both vacuums offer hazard avoidance capability, enabling them to spot and react to obstacles placed in their way in real-time. While the Roborock features an additional LIDAR sensor, resulting in faster room mapping and much-improved low-light maneuverability, the iRobot's camera-based hazard identification system is far better at spotting and reacting to obstacles. The Roborock has a more potent suction motor, resulting in better debris pickup across different surfaces, and has a mopping feature that is very effective in dealing with stains.
