Do All Robot Mowers Need Wire?

The short answer? No, not all robot mowers need wire anymore. While many entry-level models still rely on a physical boundary wire, the latest systems use GPS and RTK navigation to mow without any cable at all.

In this guide, we’ll explain the difference between wired and wire-free robot mowers, when each makes sense, and how to decide what’s best for your garden or grounds.

What Are Wired Robot Mowers?

Wired robot mowers use a perimeter cable installed around the edge of your lawn. The mower detects the signal and uses it to stay within a defined area. These systems are:

• Generally more affordable
• Suited to small, simple gardens
• Dependent on fixed layout (reinstallation is needed if your garden changes)

Most traditional domestic robot mowers fall into this category. You can browse a range of these in our garden robot mower section.

What Is a Wire-Free Robot Mower?

Wire-free mowers use satellite positioning to mow without a cable. Most modern models use RTK-GPS technology, which gives them centimetre-level accuracy and allows for flexible virtual boundaries.

This technology powers both our Sunseeker Elite mowers for homes and our commercial mowers for large grounds and sports facilities.

Wired vs Wire-Free: Key Differences

So, Which Should You Choose?

Stick with a wired mower if:

• Your garden is small and unlikely to change
• You’re looking for a budget-friendly option
• You don’t mind a bit of setup work

Go wire-free if:

• Your lawn layout is complex or might change
• You want minimal maintenance and full control via app
• You manage multiple zones or a large area
