robot lawnmower

A robot lawnmower mows your yard on a schedule, t small amounts of grass often without anyone pushing it.

Introduction

A robot lawnmower trims your grass automatically on a schedule, then drives back to its charging base when the battery runs low.

  • Boundary wire or wire-free navigation using RTK GPS or cameras
  • Rated lawn area and the steepest it can climb
  • Rain sensors, lift sensors and app controls for mowing zones

Pick a model rated above your actual lawn size. Narrow passages, steep banks and tree roots all slow it down. Wire-free mowers need a clear view of the sky for GPS, while wired models depend on a buried or pegged perimeter.

FAQs

Traditional models follow a perimeter wire you peg down or bury around the lawn. Newer wire-free mowers use RTK GPS or vision to map zones in an app, which saves setup time but needs good satellite coverage.

Many entry models manage slopes of around 20 to 35 percent. All-wheel-drive units can handle much steeper ground. Wet grass reduces grip, so stay well under the rated limit.

Blades stop when the mower is lifted or tilted, and bump sensors make it change direction. It is still wise to run it when children and pets are indoors, and to clear toys from the lawn.

Clean grass off the underside every few weeks and replace the small pivoting blades regularly. Store the unit indoors or cover the base over winter to protect the battery.

Robot mowers leave a strip along walls, fences and beds that they cannot reach. Most owners still run a string trimmer along the edges now and then.
