Robot mowers have sensors, bumpers and blades that stop when lifted, but they are still mowers. Here is how the safety features work, where the limits are, and the habits that matter.
Last updated: November 2026
Robot lawn mowers are designed with safety features such as obstacle sensors, bumpers and blade stops, and they mow slowly compared with a person pushing a mower. Still, they have sharp spinning blades, and no sensor catches everything. The safe approach is to run the robot when children and pets are indoors or out of the yard, walk the lawn for toys before runs, and teach children never to touch or ride it. Night mowing is best avoided where hedgehogs, rabbits or other small wildlife are active.
"Are robot lawn mowers safe for pets?" is one of the most searched robot mower questions. Owners on X describe dogs digging holes that trap mowers and cats watching them warily. Here is an honest look at the safety side.
What safety features do robot mowers have?
Common features, which vary by model:
Obstacle detection with cameras, ultrasonic sensors or both.
Bumpers that stop the robot when it touches something.
Lift and tilt sensors that stop the blades if the robot is picked up or tipped.
Blade guards and blades set inside the body.
PIN locks so children cannot start it.
Emergency stop on the machine and in the app.
For the Yarbo Lawn Mower Pro, Yarbo lists binocular cameras, ultrasonic sensors and a bumper for obstacle avoidance, a 20-inch cut and a cutting height from 0.8 to 4 inches.

Is a robot safer than a push mower?
In some ways, yes. Push and riding mowers cause many injuries every year, often from thrown objects, feet under decks and children near riding mowers. A robot moves slowly and stops when lifted, and no one is walking behind it. But a robot works when you are not watching, so habits matter more.
How should you introduce a robot to a dog?
Show it while off. Let the dog sniff it.
Run it with you there, at a distance, praising calm behavior.
Keep the dog inside during scheduled runs, at least at first.
Watch for chasing or biting. Some herding breeds react strongly to moving machines.
Fill holes your dog digs, so the robot does not drop in. One X owner described rescuing a robot from a hole dug by greyhounds.
What about cats and wildlife?
Cats usually avoid robots. Wildlife is the bigger concern: animals such as hedgehogs, toads and young rabbits freeze rather than run. Schedule mowing in daylight and avoid dusk and night runs. Check long grass before the first cut of the season, when nests may be hidden.
How do you keep children safe?
Set a rule: no touching, riding or chasing the robot.
Run it when children are at school or inside.
Use the PIN lock so they cannot start it.
Keep the app with adults or teach older children how to pause it.
Map no-go zones around sandboxes, play sets and trampolines.
What about a remote control mower?
With a remote control mower like the Mowrator S1, a person is watching the whole time, which many families prefer around children and pets. Mowrator lists an interference-resistant remote with a 5 ms response. You still need to keep children and pets clear of the deck while it runs, as with any mower.
Are the blades sharp?
Yes. Robot and remote mower blades are real cutting blades. Always switch off and, where applicable, lift-lock before cleaning under the deck, and wear gloves when changing blades. See robot mower blades: sharpen or replace.
What should you do after an accident or near miss?
If the robot hits an animal, a toy or a person, or you see a near miss:
Stop the robot with the emergency stop or the app.
Check for injury and get help if needed.
Check the robot for damaged blades or sensors before running it again.
Review the map and schedule. Was it running at the wrong time, or near an area that should be a no-go zone?
Tell the maker's support, especially if a sensor failed to react.
Most incidents point to a habit that is easy to change, such as a pet left outside during a run or a toy left on the lawn.
How do you teach a child about the robot?
Keep it simple: the robot is a tool, not a toy. Show them the robot while it is off, explain that it has sharp blades underneath like a kitchen knife, and agree that only adults start and stop it. Older children can learn the app's pause button for emergencies.

What sensors does the Yarbo mower use?
Yarbo lists binocular cameras, ultrasonic sensors and a bumper for obstacle avoidance on the Lawn Mower Pro module.
Should I run my robot mower at night?
It is best avoided where hedgehogs, toads, rabbits and other small animals are active. Daylight mowing is safer for wildlife.
