Instead it builds a map of your lawn using satellites with a fixed base station, cameras, lasers, or a mix, and you set the edges in an app or by driving the mower around. It saves you from laying cable, but it brings its own needs, such as a good view of the sky for some models.\u003C\u002Fp>\n\u003Ch2>What does "wire-free" mean?\u003C\u002Fh2>\n\u003Cp>Older robot mowers rely on a thin cable around the lawn that the mower senses. If that is new to you, read \u003Ca href=\"\u002Farticles\u002Frobot-mower-boundary-wire-explained\u002F\">our boundary wire explainer\u003C\u002Fa> first. A wire-free mower does not use that cable. It keeps track of where it is and where the edge is by itself.\u003C\u002Fp>\n\u003Cp>Wire-free does not mean setup-free. You still place a charging station, and you still tell the mower where to mow and where not to. You just do it on a map instead of with a cable.\u003C\u002Fp>\n\u003Ch2>How does a wire-free mower know where it is?\u003C\u002Fh2>\n\u003Cp>Makers use a few different approaches, alone or combined:\u003C\u002Fp>\n\u003Cul>\n\u003Cli>\u003Cstrong>Satellite positioning with a base station.\u003C\u002Fstrong> The mower reads signals from navigation satellites. A fixed base station placed in your yard sends corrections so the position can be much more precise. This is called RTK, short for real-time kinematic.\u003C\u002Fli>\n\u003Cli>\u003Cstrong>Cameras.\u003C\u002Fstrong> The mower uses cameras and software to recognize the lawn, edges, and obstacles. This is often called vision.\u003C\u002Fli>\n\u003Cli>\u003Cstrong>Lasers.\u003C\u002Fstrong> A LiDAR sensor measures distances with laser pulses to build a picture of the surroundings.\u003C\u002Fli>\n\u003Cli>\u003Cstrong>A mix.\u003C\u002Fstrong> Many models combine two of these.\u003C\u002Fli>\n\u003C\u002Ful>\n\u003Cp>Our plain comparison of the three is in \u003Ca href=\"\u002Farticles\u002Frtk-vs-lidar-vs-vision-robot-mowers\u002F\">RTK vs LiDAR vs vision\u003C\u002Fa>.\u003C\u002Fp>\n\u003Ch2>What do you do instead of laying a wire?\u003C\u002Fh2>\n\u003Cp>The steps vary by maker, but the idea is the same.

You can walk or drive the mower around the lawn edge using the app, or you can follow the mower as it traces the area. Which methods a model supports depends on the model.\u003C\u002Fli>\n\u003Cli>\u003Cstrong>Mark no-go areas.\u003C\u002Fstrong> Draw or drive around flower beds, ponds, and play areas so the mower treats them as off limits.\u003C\u002Fli>\n\u003Cli>\u003Cstrong>Set a schedule\u003C\u002Fstrong> and let it run.\u003C\u002Fli>\n\u003C\u002Fol>\n\u003Cp>Because the map lives in software, changing your lawn later usually means editing the map, not moving cable. Check how your model handles that.\u003C\u002Fp>\n\u003Ch2>Who benefits from going wire-free?\u003C\u002Fh2>\n\u003Cp>Wire-free tends to suit people who:\u003C\u002Fp>\n\u003Cul>\n\u003Cli>Do not want to lay or bury a cable.\u003C\u002Fli>\n\u003Cli>Have a lawn with an awkward shape or several separate zones, where the map can make planning easier.\u003C\u002Fli>\n\u003Cli>Expect to change the layout later, such as adding a bed or a patio.\u003C\u002Fli>\n\u003Cli>Are comfortable using an app for setup.\u003C\u002Fli>\n\u003C\u002Ful>\n\u003Cp>It may suit you less if you want something that works without an app, or if your yard has conditions that make positioning harder (see below).\u003C\u002Fp>\n\u003Ch2>What are the trade-offs?\u003C\u002Fh2>\n\u003Cul>\n\u003Cli>\u003Cstrong>Sky view.\u003C\u002Fstrong> Models that use satellite positioning need a clear view of the sky. Tall trees and tall buildings can block it, which can make positioning less reliable in those spots.\u003C\u002Fli>\n\u003Cli>\u003Cstrong>Base station.\u003C\u002Fstrong> Some models need a separate base station, placed with a clear view of the sky, plus power.\u003C\u002Fli>\n\u003Cli>\u003Cstrong>App setup.\u003C\u002Fstrong> Most setups happen in a phone app, so you need a phone and, for some models, a connection.

We cannot say from our data why the numbers differ. It may depend on how makers describe the setup, or the field may be blank for some models. Check the maker for the exact equipment in the box.\u003C\u002Fp>\n\u003Ch2>For the details-minded\u003C\u002Fh2>\n\u003Cp>A fixed base station knows its own exact location, so it can tell the mower how much the satellite signals are off at that moment. This is what lets RTK models claim centimeter-level position. Vision and LiDAR systems build a map from what the mower sees and measures, and many models fuse more than one source. How a mower handles a moment when one source is weak, such as under a tree, is a design choice. The maker's documentation is the place to look.\u003C\u002Fp>\n\u003Ch2>What this means for you\u003C\u002Fh2>\n\u003Cp>Wire-free is a good fit to explore if cable work is what puts you off.

Wire-free removes cable work but depends on sensors and setup in an app. A wire is simple and physical but takes effort to install.\u003C\u002Fp>\n\u003Cp>\u003Cstrong>Do all wire-free mowers need a base station?\u003C\u002Fstrong>\nNo. In our catalog, 37 models are listed as needing an RTK base station, and others use cameras or lasers instead. Check the model.\u003C\u002Fp>\n\u003Cp>\u003Cstrong>Can I still set no-go zones?\u003C\u002Fstrong>\nMakers say yes.
