iRobot Roomba j7/j7+ vs eufy E20

The iRobot Roomba j7+ is a better robot vacuum than the eufy E20. The j7+'s performance across almost all floor surfaces is a bit better, and it's a bit quieter than the eufy. Both robot vacuums do a great job with obstacle avoidance, although they take very different approaches. The j7+'s camera-based object avoidance system leaves a large space between the vacuum and the object, also leaving uncleaned areas around obstacles. By contrast, the eufy's LIDAR-based system allows the vacuum to get in very close; it's able to clean more effectively, but occasionally hits objects or gets stuck.
