iRobot Roomba j7/j7+ vs Roborock Q5/Q5+

The Roborock Q5 is better than the iRobot Roomba j7. The Roborock delivers better cleaning performance on bare floors as well as low- and high-pile carpets, and its LIDAR sensor maps out its coverage area much faster than the camera-based iRobot. It can also run for a lot longer on a single charge. Conversely, the iRobot is a better option for pet owners. Its hazard-detection system allows it to spot and react to hazards like pet waste or power cords in real-time, so you don't have to make sure that its cleaning area is completely free of obstacles before letting it run. If you're considering purchasing either vacuum with a self-emptying base station, the iRobot's external dirtbag has a slightly larger overall capacity, and its twin rubber brushrolls are much easier to clean than the Roborock's bristled roller.
