The straight answer
Robot mowers have safety features, but no mower is completely risk‑free for wildlife or pets. The most effective risk reduction is how you operate it: when you mow, where you mow, and what you check before it runs.
In the UK, the biggest wildlife concern is mowing at night when hedgehogs are active. A simple change — mowing in daylight hours — is often the highest‑leverage step.
This guide focuses on practical, responsible habits rather than reassurance.
Why night mowing is the main issue (UK context)
Hedgehogs are more active at night. If a mower runs through the night, the chance of an encounter rises.
Daytime mowing reduces the risk substantially. Many owners set the mower to run late morning through early evening windows, especially in spring and summer.
If you’re buying a robot mower, plan your schedule around wildlife first, convenience second. You can still get a tidy lawn.
Not sure if your garden is suitable?
Most robot mower headaches come from mismatching the mower type to the layout. A quick assessment can save you money and frustration.

Pets: what typically happens
Most pets (dogs and cats) either ignore the mower after an initial sniff or keep a sensible distance. Problems tend to occur during the first few days when curiosity is highest.
Best practice: supervise early interactions, keep pets indoors during the first few mowing cycles, and make sure your mower’s safety settings are enabled.
If you have very small pets or animals that spend time in long grass, be extra cautious and keep mowing to supervised daylight windows.
Safety features: what they do (and what they don’t)
Most mowers include lift and tilt sensors that stop the blades when the mower is lifted or flipped. Many also have collision detection.
These features reduce risk, but they don’t remove risk in every scenario. Wildlife can behave unpredictably, and different models behave differently around small animals and obstacles.
Treat safety features as a back‑up, not your primary protection.
Practical risk reduction: a simple routine that works
1) Daylight mowing: avoid running overnight.
2) Lawn check: a quick glance for animals before the first run of the day, especially in long grass or near hedges.
3) Keep edges tidy: long rough patches along fences/hedges can become hiding areas. If you have a wild corner, consider making it a stay‑out zone.
4) Reduce surprise encounters: avoid mowing when you’ve just moved piles of leaves, logs, or garden debris.
5) Consider seasonal changes: spring and autumn behaviour differs; adjust schedules accordingly.
Garden design: where to create safe areas
If you’re wildlife‑friendly, consider creating a defined ‘wild corner’ that’s fenced off or designated as a stay‑out area for the mower. This gives wildlife shelter without putting it directly in the mower’s path.
Installers can set stay‑out zones (wired islands or virtual exclusions). Use that feature proactively rather than waiting for a near‑miss.
A tidy lawn and a wildlife‑friendly garden can coexist if you plan zones.
What to ask installers (important if you’re concerned)
Ask: Can you set up a schedule that avoids overnight mowing? Can you create stay‑out zones around hedges or wildlife areas? Will you show me how to adjust the schedule easily?
If the installer dismisses concerns with ‘it’ll be fine’, that’s not the right tone. You want practical steps, not reassurance.
Set schedules that are both wildlife-safe and practical
Most lawns don’t need 24/7 mowing. A robot mower that runs a few hours in daylight can maintain a tidy finish because it cuts little-and-often.
If you have a larger lawn, extend daytime runtime rather than shifting into night hours. In summer, longer daylight makes this easier.
If you must run early/late, avoid the deepest night hours and check the garden first. The safest default is daylight mowing.
Stay‑out zones: the underrated feature
Many gardens have areas where wildlife shelters: hedges, log piles, compost corners, dense shrubs. Rather than mowing right up to them, designate a stay‑out zone and tidy the boundary manually on your own terms.
This is also good for reliability: robots can get stuck in rough wildlife corners and repeatedly attempt the same failing route.
Tell your installer where you want ‘wild’ areas to be and ask them to set exclusions from day one.
If you want to be wildlife‑friendly without losing the convenience
The practical compromise is: run the mower in daylight, create a defined wild corner as a stay‑out zone, and keep the rest of the lawn consistently short so animals are less likely to shelter in the cutting area. If you have dense hedges, don’t mow right up to them at night — keep a small buffer strip and trim it manually when you’re in the garden. These steps reduce risk without turning ownership into a daily chore.

Next step: set a responsible mowing plan
If you’re getting quotes, mention wildlife and pets upfront. It helps the installer plan zones and schedules properly.

FAQ
Should I stop using a robot mower if I have hedgehogs?
Not necessarily, but you should adjust operation. Daylight mowing and sensible stay‑out zones are key. If you frequently see hedgehogs in your garden, be extra cautious.
Is it safer to mow less often?
Not automatically. Frequent light cuts in daylight can be safer than rare long cuts at night. Prioritise schedule timing and checks.
Can installers set up wildlife-friendly zones?
Often yes. They can create exclusions around hedges, wild corners, ponds, and other areas you want to protect.
Do I need Wi‑Fi for a robot mower?
Not necessarily. Many use Bluetooth for setup and work independently day-to-day. Some features (app control, alerts, updates) may work better with Wi‑Fi or mobile coverage, depending on model.
Will it replace edging completely?
Usually not. Many gardens still need occasional edge trimming, especially with raised borders, brick edging, or narrow strips the mower can’t reach safely.
Is professional installation worth it?
If you have slopes, multiple zones, narrow passages, or you want wire-free, professional installation usually reduces call-outs and improves reliability.
Is it safer to use a boundary wire for wildlife?
Navigation type doesn’t remove wildlife risk. Schedule timing (daylight) and zone planning are the main levers.
Can I pause mowing during hedgehog season?
Yes. Many owners adjust schedules seasonally. If your lawn grows quickly, increase daytime runtime rather than night mowing.
What about other wildlife like frogs?
Any small animal in the mower’s path is a potential risk. Daylight operation, checks, and stay‑out zones reduce encounters.

Reality check: design for your worst week
A practical way to sanity-check a robot mower plan is to think about your worst week, not your best. If your lawn gets soggy after a few days of rain, or you have a narrow choke point that’s hard even for a push mower, that’s where a robot will struggle unless the installation is designed around it. In the UK, the ‘boring’ details—drainage, edging, and where the mower turns—often matter more than headline features.
