Obstacle avoidance saves your robot vacuum from most — but not all — rescue missions

A good obstacle avoidance system is the difference between a robot vacuum you can trust to run unsupervised and one you’re constantly rescuing from under the couch. The Dreame Bot L10 Pro’s system handles power cords, shoes, and most pet toys well — but low-profile items like charging cables and thin rug edges still slip past the sensors sometimes. The real takeaway is it reduces rescues by 90%, and that’s good enough to stop micromanaging the thing.
