Robot lawn mowers have changed enormously in recent years. While older models often required perimeter wires to be installed around the lawn, the latest robotic mowers can use cameras, RTK positioning, LiDAR and intelligent mapping to navigate your garden with far less setup.
That also means there is now much more to consider when choosing one.
The best robot lawn mower for your garden depends on factors including lawn size, layout, slopes, narrow passages, surrounding trees and buildings, navigation technology and how much automation you want.
In this guide, we compare five robot lawn mowers available from Foy's Electrical, with options for lawns from around 500m² right up to 1600m².

Which Robot Lawn Mower Is Best for Your Garden?
The easiest place to start is with the size of your lawn.
For smaller gardens of up to around 500m², the Einhell FREELEXO CAM 500 offers camera-based automated mowing without requiring a traditional perimeter wire around the entire lawn.
For lawns up to 600m², the ECOVACS GOAT O600 RTK adds more advanced mapping, RTK navigation and intelligent obstacle avoidance.
The GOAT O800 RTK increases lawn coverage to 800m² and provides a wider cutting system and greater mowing efficiency, making it an excellent option for medium-sized gardens.
For larger or more complex lawns, the GOAT O1200 LiDAR PRO introduces Dual-LiDAR navigation and integrated edge trimming.
Finally, for lawns approaching 1600m², the GOAT A1600 LiDAR PRO combines a significantly wider cutting system with much greater mowing efficiency.
Do Robot Lawn Mowers Need Boundary Wires?
One of the biggest developments in robotic lawn mowing is the move away from traditional perimeter wires.
Older robot mowers commonly relied on a physical wire installed around the lawn to tell the mower where it could and couldn't go.
Modern robot lawn mowers can instead use technologies including cameras, RTK positioning and LiDAR to identify boundaries, map the garden and determine their position.
All five robot lawn mowers featured in this guide can operate without installing a traditional perimeter wire around the entire lawn, although they use different technologies to achieve this.
For homeowners, this can make initial installation considerably easier and provide greater flexibility when configuring mowing areas.
What Is RTK on a Robot Lawn Mower?
RTK stands for Real-Time Kinematic positioning.
In simple terms, it enhances satellite positioning to give compatible robot lawn mowers much greater positional accuracy than standard GPS alone.
Robot lawn mowers such as the ECOVACS GOAT O600 and O800 combine RTK positioning with cameras and additional sensing technology to accurately navigate around mapped lawn areas.
What Is LiDAR on a Robot Lawn Mower?
LiDAR uses laser-based sensing to measure the mower's surroundings and help build a detailed representation of the environment.
The ECOVACS GOAT O1200 LiDAR PRO and A1600 LiDAR PRO use Dual-LiDAR navigation, allowing them to navigate without relying on an external RTK reference antenna.
This can be particularly useful in more complicated gardens or environments surrounded by trees and buildings.
What Size Robot Lawn Mower Do I Need?
You should generally choose a robot lawn mower with a recommended lawn capacity that comfortably accommodates the area you want it to maintain.
However, total lawn area isn't the only consideration.
A relatively small garden can still be challenging for a robot mower if it contains multiple lawn zones, steep slopes, narrow connecting paths, trees, flower beds or complicated boundaries.
Likewise, a large but open and relatively simple lawn may present fewer navigation challenges.
When choosing a robot lawn mower, consider:
-
Total lawn area
-
Number of separate mowing zones
-
Narrow passages
-
Slopes and uneven terrain
-
Trees and surrounding buildings
-
Lawn boundaries and edges
-
Obstacle avoidance
-
Navigation technology
-
Cutting width and mowing efficiency
Matching the mower to the layout of your garden as well as its size will help you choose the most appropriate model.
Are Robot Lawn Mowers Worth It?
For anyone who spends a significant amount of time mowing during the growing season, a robot lawn mower can make lawn maintenance considerably easier.
Rather than waiting for the grass to become long and then carrying out a major cut, robotic mowers are designed to maintain the lawn regularly by removing smaller amounts of grass more frequently.
Once correctly configured, the mower can follow its schedule, maintain the lawn and return to its charging station automatically.
That makes robot lawn mowers particularly attractive for busy households, larger gardens or simply anyone who would prefer to spend less time pushing a conventional lawn mower.
The important thing is choosing a model appropriate for your particular garden rather than simply choosing the mower with the longest list of features.
