Best robot vacuums for obstacle avoidance

Robot vacuums that see a charging cable, a sock and a dog bowl for what they are, and go round them.

An obstacle sensor is what decides whether you tidy the floor before every run. Infrared sees a wall; a camera with a depth sensor sees a cable and knows to leave it. Weighted on recognition above everything else, with value deliberately at zero — this ranking answers one question, and price is not it.
