Robot lawn mowers are no longer futuristic gadgets—they’re here, work, and change how people care for their lawns. But it pays to know exactly what they can (and can’t) do before you invest. From battery life and safety features to how they handle rain, slopes, and even dog poop, there’s a lot to consider.
In this article, we break down 26 things you need to know before buying a robot lawn mower so that you can make an informed choice. We'll cover how robot mowers work, lawn care, performance and features, cost and maintenance, and more.

How Robot Mowers Work
1. What is a robot lawn mower?
A robot lawn mower is an automated mower that cuts your grass without any manual effort. It uses sensors, GPS, or RTK navigation to map your lawn and mow automatically.
2. Do they really work?
Modern mowers cut evenly and frequently, keeping your lawn looking freshly maintained all year.
3. How do they navigate?
They use GPS, RTK positioning, or sensors to map the lawn, detect obstacles, and mow in precise patterns.
4. Do you still need perimeter wires?
Older models required buried wires, but most modern RTK GPS models operate completely wire-free.
Safety and Lawn Care
5. Are they safe around pets and children?
Yes. Safety is a priority—blades are enclosed, and sensors stop the mower if it’s lifted or bumped.
6. How do they handle obstacles?
Sensors and cameras detect trees, garden beds, and furniture, mowing safely around them.
7. Do they collect grass clippings?
No. Robot mowers mulch the grass, returning nutrients to the soil for a healthier lawn.
8. Do you still need to edge your lawn?
Yes. Mowers get close to edges but may leave small strips along walls or fences. A quick whippersnip finishes the job.
9. What about dog poop?
Different models handle it differently—some mulch over it, while AI-enabled mowers drive around it.
Performance and Features
10. Can they handle hills?
Standard models handle gentle slopes; AWD models manage gradients up to 75%.
11. How much lawn can they mow?
Entry-level models cover up to 1,000m², while commercial models handle 70,000m² or more.
12. Can they mow in the rain?
Most can mow in light rain, though wet grass can affect cut quality and traction.
13. Can they mow at night?
Yes. They’re quiet enough not to disturb neighbours.
14. Can you control them with your phone?
Modern models have mobile apps for scheduling, monitoring, and boundary adjustments.
15. Can they manage multiple zones?
Yes. RTK/GPS systems let you set up multiple virtual zones for front and back yards.
16. What if your yard has trees or poor satellite coverage?
Modern RTK models combine satellite signals with AI cameras, enabling accurate mowing even under trees.
Cost and Maintenance
17. How much do robot lawn mowers cost?
Residential robot lawn mowers start around $1,500 and can rise to $8,000 for larger units designed for acreages. Brands such as Kress, Mammotion, Segway, and MoeBot offer the best solutions with models at varying price points and capabilities.
Commercial robot lawn mowers range from $10,000–$50,000+ and come with widespread applications for schools, businesses, farms, sportsgrounds and public spaces. For example, the FJDRM21 by FJ Dynamics is a robotic lawn mower and line marker.
Bundles and kits like those on our website also provide a more accessible entry into robotic lawn mowers.
18. Do they increase electricity bills?
Only slightly. They’re highly energy-efficient, costing just a few dollars per month. But if you run solar, it should make no difference as long as it charges during the day or from a solar battery.
19. How long do the batteries last?
Most run 60–180 minutes per charge, then return to base to recharge. Batteries typically last 2–5 years.
20. How much maintenance do they need?
Minimal. Occasional cleaning, blade replacement/sharpening, and app updates are usually all that’s required. Blades are cheap and easy to replace yourself.
21. How long do they last?
With proper care, most robotic lawn mowers last 7–10 years, with battery replacements every 2–5 years.
Seasonal Use and Commercial Applications
22. What happens in winter?
You can park the mower during dormant periods or run it on a reduced schedule. Winter is also a good time for servicing.
23. Are they suitable for commercial use?
Yes. Councils, schools, golf courses, and turf farms use robotic mowers for consistent results, cost savings, and noise reduction.
There has also been a large increase in the number of remotely controlled mowers for commercial use, with brands like Raymo pioneering the technology.
Theft and Security
24. Can they be stolen?
While possible, it’s rare. Most include GPS tracking, PIN codes, and anti-theft alarms. A stolen mower is useless without the owner’s app.
Choosing the Right Mower
25. How do you choose the right mower?
Consider lawn size, slopes, obstacles, and desired features. Experts at Robot Mowers Australia can advise, demonstrate, and install the best model for your yard.
Extra Considerations
26. Do robot mowers really save money?
While upfront costs are higher than traditional mowers, time savings, energy efficiency, and reduced maintenance make them cost-effective in the long run.
Robot lawn mowers are a game-changer for busy homeowners, offering convenience, safety, and a consistently well-maintained lawn. By understanding these 26 factors, you can choose the right mower for your space and lifestyle.
