Short answer
Some can, but none reliably enough to trust completely. Robots with a front camera and object recognition can spot and avoid pet waste much of the time. Robots without a camera can't see it at all. Your routine matters as much as the robot.
Why it matters
A robot that runs over pet mess doesn't stop. It carries the mess on its wheels and brushes through every room it cleans afterwards. Cleaning the floors is only half the job, because the robot itself will need a thorough clean too.
What stops it happening
- Don't run the robot unsupervised while pets are still learning. Puppies, kittens and older pets with accidents are the highest risk. Avoid overnight runs and runs while you're out.
- Check the floor before it starts. A quick look along the robot's usual route takes seconds.
- Choose a robot with a camera-based obstacle system. Robots that only use LiDAR or bump sensors can't recognise what's in front of them.
- Use no-go zones around litter trays and feeding areas.
Robots that do this best
@vacuumnerds rates the Roborock Saros 20, Dreame X60, Narwal Flow and Narwal Flow 2 well for pet-waste avoidance, and notes that none is perfect. See each profile for what other reviewers found.
Rated well for pet-waste avoidance
Roborock Saros 20ReviewedRoborock's new top-of-the-range vacuum and mop for 2026. Very strong on hard floors and unusually good at getting over door bars and under furniture, but less certain on thick carpet and clutter.
Dreame X60 Pro Ultra CompleteReviewedDreame's 2026 flagship for the UK and Europe, with a long mop arm and legs that lift it over tall steps. Two home testers loved it; a French lab found edges and obstacles weaker than promised.
Narwal FlowReviewedNarwal's first robot with a flat, track-style mop that rinses itself while it cleans. Testers rank the mopping among the best they've seen; the vacuuming, routes and app are far less consistent.
Narwal Flow 2ReviewedNarwal's 2026 flagship keeps the self-rinsing track mop and adds much more suction and smarter cameras. It mops brilliantly and dodges clutter well; edges, corners and larger crumbs are where it slips.
