Robotic lawn mowers have quickly become a staple in UK gardens, offering hands-free maintenance and more consistent cutting results than traditional mowers. But as more homeowners consider going robotic, one key question keeps popping up: should you go for a GPS-powered mower or stick with the classic boundary wire system?
Each system offers its own approach to navigation. While boundary wire models have been the industry standard for years, GPS-based systems, especially those using RTK (Real-Time Kinematic) technology, are rapidly gaining attention for their ease of use and wire-free setup.
In this article, we'll break down how each system works, compare their strengths and weaknesses, and help you determine which is better suited for your garden—whether it’s a neat suburban patch or a more complex, sloped layout. Let’s settle the GPS vs boundary wire debate once and for all.
How Robot Lawn Mowers Navigate: GPS vs Wire Explained
To understand which robotic lawn mower is better for your garden, it's important to first understand how they actually find their way around.
Robotic mowers navigate using either a boundary wire system—installed physically around the lawn—or GPS-based systems, often using RTK (Real-Time Kinematic) precision. Both methods aim to ensure the mower stays within the designated area and cuts efficiently, but they differ significantly in setup, accuracy, and flexibility.
Let’s look at how each works.
What is a Boundary Wire Robot Mower?
Boundary wire mowers rely on a physical wire installed around the perimeter of your lawn, often pegged into the grass or buried just below the surface. This wire emits a low-voltage signal that the mower detects, telling it where the garden ends.
This system is tried-and-tested and still used in many models, from Flymo EasiLife to Husqvarna Automower. However, installation can be time-consuming, and changing your garden layout later means repositioning the wire.
These mowers tend to be more affordable up front, but their reliance on a fixed border makes them less flexible than newer alternatives.
What is a GPS Robot Mower?
GPS robot mowers—especially those using RTK technology—don’t need boundary wires at all. Instead, they rely on satellites and a fixed base station to achieve centimetre-level accuracy in mapping and mowing your garden.
Models like the Mammotion YUKA Mini are equipped with smart mapping features, allowing you to draw digital boundaries via app and customise mowing zones. No digging. No cabling.
They’re especially useful for larger, complex, or frequently changing gardens. The main trade-off? GPS mowers tend to be pricier, and consistent satellite access is required for peak performance—but Mammotion developed the world's first NetRTK+Vision system, which significantly improves the navigation accuracy of the Mammotion robot lawn mower.
Pros and Cons: GPS vs Wire Robot Mowers
When choosing between a GPS robot lawn mower and a boundary wire model, it’s essential to weigh the trade-offs clearly. The table below breaks down the key differences to help you quickly identify what best fits your garden and lifestyle:

Verdict: If you want future-proof, smart lawn care and minimal fuss, GPS models are increasingly the better investment—especially for medium to large or complex UK gardens. However, wired models still make solid, cost-effective choices for small, straightforward lawns.
Real-World Use: Which One Fits UK Gardens Better?
British gardens are wonderfully diverse—some are narrow and fenced, others multi-zoned with patios, ponds, or raised beds. Add to that our famously unpredictable weather, and you’ll see why not all robot mowers perform equally in real-world UK conditions.
Boundary wire mowers are generally better suited to small, enclosed gardens with clear perimeters. They operate reliably rain or shine, and their tried-and-tested nature means there’s a wide range of affordable options on the market. However, if your lawn is divided into different sections, surrounded by decking, or has frequent design changes, the limitations of physical wiring quickly become frustrating.
GPS-based mowers like the Mammotion YUKA Mini shine in complex or evolving spaces. You can define multiple zones digitally (e.g. front and back gardens, or a section with wildflowers you want to skip), and re-map them without ever lifting a spade. The RTK positioning also means neat, stripe-like mowing patterns—something wire systems can’t offer.
That said, smaller gardens with tall fences or poor satellite visibility may limit GPS performance. In these cases, a quality wire mower remains a dependable choice.
Top GPS and Wire Robot Mower Models to Consider in 2025
Whether you're leaning towards a GPS model or a traditional boundary wire mower, choosing the right machine is key. Here are some of the most reliable and well-reviewed robot lawn mowers available in the UK for 2025, across both categories.
