Good question—generally, light leaf coverage isn’t a problem, but heavier fall can be.
Vision-guided mowers like the Luba 2 Mini and Eufy rely on cameras to identify obstacles, so scattered leaves will usually just get mulched as they mow. However, if the lawn is heavily covered, leaves can sometimes be “seen” as obstacles or make navigation a bit less reliable.
That said, you do have some control—you can adjust the obstacle avoidance sensitivity and even define certain areas as obstacle-free zones, which helps prevent the mower from overreacting to things like leaves.
In practice, during peak autumn you may still need to step in occasionally—either clearing heavier patches or mowing more frequently to keep things manageable. Mark
