How this ranking is built
We rank models by how often owners mention obstacle avoidance in their comments. This list reflects real-world usage and satisfaction, not lab tests. With fewer than five models mentioned, treat this ranking as directional. Obstacle avoidance uses cameras, structured light, or AI to detect and navigate around objects. Better avoidance means fewer rescues and less damage to furniture or the robot. Look for models that can identify pet waste, cables, and shoes.
