The good ones with AI obstacle avoidance, usually yes — and several brands will replace the robot if it fails. The cheap ones with no camera, absolutely not. If you have pets, do not buy a robot without AI obstacle detection.

What separates the ones that dodge it

Pet waste avoidance requires the robot to identify what an object is, not just detect that something is there. That means a forward-facing camera with an AI model trained to recognize it. A bump sensor can’t do it, and neither can LiDAR on its own — LiDAR sees an obstacle and steers around it only if the object is tall enough to register, which pet waste often isn’t.

Several brands are confident enough in their systems to offer a replacement guarantee if the robot fails at it. That guarantee is a reasonable signal, but read what it actually covers before you rely on it.

Who really needs this feature

A puppy that isn’t fully house-trained. An older dog having accidents. A cat with strong opinions about the litter box. A doggie door that lets the dog in and out unsupervised while you’re at work, which is my situation.

If any of those describe your house, treat AI obstacle avoidance as a requirement rather than an upgrade. The failure mode here isn’t a dirty floor — it’s the robot tracking it through every room it visits afterward, and then into the dock. I’ve watched it happen. There’s no cleaning that up quickly and there’s a real chance you’re throwing out parts.

This is the one feature I will not tell anybody to economize on.

Dad’s Take

With pets, this isn’t a nice-to-have. It’s the difference between a bad afternoon and a very bad afternoon.
