Can a Robot Mower Cut Your Foot? What the Sources Say
7 min read · by Rachel Whitman · Updated
Can a robot mower cut your foot? Yes, if a foot reaches a spinning blade. A robot mower cuts with blades that turn while it runs, so contact can cause a serious cut. Lift and tilt sensors are designed to stop the mower when it is picked up or tipped, but the sources we read do not give a robot-specific injury count.
The short answer
- Yes, in principle. A running blade can injure a foot or hand that reaches it. The U.S. Consumer Product Safety Commission (CPSC) says toe amputations are not uncommon with homeowners cutting grass.
- Sensors reduce risk, they do not remove it. Husqvarna describes a lift alarm that triggers when the mower is picked up or tilted beyond its permitted angle.
- Keep feet clear while it runs. Our reading: treat the mower as live until its display and manual confirm it is off.
Can a robot mower cut your foot?
Yes, a spinning blade can cut a foot that reaches it. The CPSC notes that emergency surgery is sometimes needed for severe injuries from hand or foot contact with a rotating blade, and it describes toe amputations as not uncommon with homeowners cutting grass. Those figures come from walk-behind mowers, which a person pushes.
A robot mower differs in one way: nobody guides it across the lawn. Our reading is that the realistic risk is someone reaching toward or under the deck while the blade may still be turning, such as a child, a pet, or an adult checking a stuck mower by hand.
What the lift and tilt sensors do
Lift and tilt sensors are the protection the sources describe for a robot mower that is picked up or tipped. Husqvarna’s support page says the Automower shows “Lifted” or “Alarm! Mower was lifted” when its lift sensor detects that the mower has been picked up or tilted beyond the permitted angle, and that the mower then stops.
- Trigger: the mower is picked up, or tilted beyond the permitted angle.
- Stop: the Automower stops and displays the alarm message.
- Restart: if the alarm is active, the owner enters the PIN code to clear it, then restarts the mower.
The support page says the mower stops, but it does not say what the blades do. Husqvarna’s US Automower FAQ states that when the mower is lifted, “the blades automatically and immediately shut off.” That is one brand’s statement. We did not confirm blade behavior for other brands, so check the owner’s manual for the model you are considering.
Why a lift alarm is not a guarantee
A lift alarm is a stop function, not a guard around the blade, so the answer to can a robot mower cut your foot does not change because a sensor exists. Husqvarna lists several things that can trigger it without anyone lifting the mower, including driving over raised objects such as tree roots or stones, and the tilting motion when the mower works near a slope (see our guide to robot mower slope rating explained).
Other triggers on the same page include high or thick grass, a low cutting height, gravel or paved surfaces, debris under the deck, and a loose body. An alarm stops the mower until the owner clears it, so a stopped mower is not a finished job and should be checked before anyone works near it.
What the CPSC figures cover
CPSC reports that an average of 35,000 people a year were treated in U.S. emergency rooms for walk-behind power mower injuries from 2013 through 2015. The federal blade safety standard for walk-behind rotary mowers took effect on June 30, 1982, and requires a blade brake to stop the blade within three seconds after the operator releases the control bar.
These rules apply to walk-behind rotary mowers. They do not describe robot mowers, so do not read the 35,000 figure as a robot mower injury count.
Keep toys, tools and pets clear while it runs
The steps below are our reading of the sources, not a manufacturer checklist. Use them before and during each mowing session.

- Clear the lawn first. Pick up toys, hoses, sticks and loose objects (see how robot mowers avoid obstacles), since Husqvarna lists debris and raised objects among the things that can trip the sensors.
- Keep people and pets inside or away. Our reading: keep children and pets out of the mowing area while the mower is running. More on this is in robot mower safety for kids and pets and in how robot mowers react to animals.
- Never reach under a running mower. If it is stuck or tilted, follow the manual and wait for it to stop before touching the deck. Husqvarna’s US FAQ says to press STOP, then hold the ON/OFF button for 3 seconds and confirm the indicator lamp is off before cleaning, and to wear protective gloves for maintenance. A repeat stop in one place is covered in robot mower stuck in the same spot.
- Enter the PIN and move it by hand. When the alarm is active, enter the PIN code, then move the mower by hand to a flat, clear surface before restarting it.
What to check before you buy
Use the owner’s manual and the product page to check how a model handles lifting, tilting and restart. If you are comparing models because of the question can a robot mower cut your foot, these checks give a clearer answer than any general rule. The table below lists what to look for and where to confirm it.
| What to check | Why it matters | Where to confirm |
|---|---|---|
| Lift alarm | Stops the mower when it is picked up or tipped | Owner’s manual, alarm section |
| Tilt angle | Sets when the mower stops on a slope | Specification sheet |
| Blade stop on lift | Shows whether the blades stop with the wheels | Owner’s manual, safety section |
| PIN code | Needed to clear an active alarm and restart | Setup guide |
Heads up
We did not find robot-specific injury counts, and we confirmed blade shut-off on lift only for Husqvarna. Treat those points as open questions for any other manufacturer.
Watch the first runs
Watch the first few runs before you leave the mower to work alone. Read the alarm section of the manual first, so you know what the display shows when the mower stops and which steps clear it. Until you know how your model behaves, the safe answer to can a robot mower cut your foot is to stay clear of it while it runs.

Frequently asked questions
Do robot mowers stop when they are lifted?
Husqvarna says its lift sensor triggers an alarm when the mower is picked up or tilted beyond the permitted angle, and the mower stops. Husqvarna’s US FAQ adds that the blades shut off immediately when the mower is lifted. Check the manual for the model you own, because we did not confirm this for other brands.
What should I do after a lift alarm?
Husqvarna says that if the alarm is active, you enter the PIN code to stop it, then restart the mower. If the mower is stuck, move it by hand to a flat, clear surface first.
Are robot mowers safer than walk-behind mowers?
We did not find a robot-specific injury count in the pages we read. The CPSC figures cover walk-behind mowers, so they do not settle the question for robots.
Should children and pets stay inside while a robot mower runs?
Our reading is yes: keep them away from the mowing area while it runs, and wait until the mower is off before anyone works near the deck.
