For some, mowing the lawn is a leisurely pastime — a nice way to spend a Sunday afternoon. For the rest of us, however, it’s a chore. In fact, we can think of a better way to spend a Sunday afternoon: relaxing in the sunshine while a robot lawn mower does the hard work for us. That really is a leisurely pastime.

Indeed, a robot lawn mower is a worthwhile investment that will make cutting the grass much less of a chore. Think of robot vacuums, like the ever-popular Roomba, but for the garden. Simply programme it and put your feet up. Away it goes.

Deciding to invest in a robot lawn mower is easy. But choosing the right model for you is a job as arduous as pushing a petrol mower up an especially steep garden path. That’s why we’re here to help. Here’s some need-to-know robot mower info.

How do robot lawn mowers work?

Robot mowers are battery-powered and, for the most part, run automatically based on a pre-programmed schedule, which the user sets up via an app. When they’re not running, they sit safely docked in a charging port plugged into an outdoor outlet.

When it’s time to mow, they cut your grass to a predetermined height and generate grass clippings so fine that they essentially become mulch. Whereas you’d take a traditional mower to the lawn when the grass gets a bit long, a robotic mower will usually run daily to cut just the top of your lawn and keep it at a set level. The cutting height options may vary model to model.

How do robot lawn mowers know where to cut?

Robot mowers learn where to mow based on a perimeter wire, which you’ll lay around the edges of your lawn to form a boundary. It’s like an invisible forcefield that the mower automatically detects. Setting up your perimeter wire can be a bit of a headache. In fact, the majority of negative user reviews involve the perimeter wire in some way. The companies featured in this roundup offer fairly comprehensive installation guides on YouTube in addition to the instructions in the package.

Robot mowers are an example of fairly new technology in the grand scheme of things, so the category still has a few kinks to work out. It’s possible, for instance, that the mower will miss a spot or two and you’ll need to go back over it with some clippers.

What features do robot lawn mowers offer?

Consider at least three basic categories: garden size, hills, and budget. The mowers on this list are generally better suited to gardens under one acre. Each mower also lists the maximum incline it’s able to climb while still achieving a successful cut. In general, you’ll pay more if you want more ground covered and higher hills climbed.

Other things to keep in mind include integrated rain sensors, companion app quality, weather resistance, and GPS, which are addressed in the recommendations below. You might also want to consider the ability to navigate narrow passages, adjust to weather conditions, or the ability to cut to the edges or around tricky areas.
