Our Verdict

iRobot Roomba j7+ is the better choice if your priority is hands-off vacuuming, obstacle recognition, and a Clean Base that empties the robot for weeks at a time. Roborock Q8 Max is the better fit if you want one robot to vacuum and mop, prefer LiDAR mapping, want a clearly stated 5,500 Pa suction figure, and do not need the self-empty dock included in the base model.
