iRobot Roomba j7/j7+ vs Roborock S7 MaxV

The Roborock S7 MaxV is better than the iRobot Roomba j7. The Roborock has an impressively effective mopping feature, a much longer maximum battery life, and it performs considerably better on bare floors and high-pile carpets. Like the Roborock, the iRobot uses cameras that let it identify and react to hazards like pet waste in real-time. However, the Roborock also has a LIDAR sensor for quicker and more precise room mapping. While the iRobot is compatible with a self-emptying base station, the Roborock is fully compatible with the Empty Wash Fill Dock, which not only empties its dustbin but washes its mop pads and refills its internal water reservoir, though this accessory is very expensive.
