Best robot lawn mower for large lawns 2023 - Our top picks

If you're looking for the best robot lawn mower for large lawns, we've got you covered right here.

Robotic lawn mowers have grown in popularity over the last few years and have become an easy method for taking care of your lawn. This is especially true for larger gardens that'll take longer to mow.

You'll be wanting to keep an eye on the cutting width of these devices, as it will determine how wide of an area it can cut in one swoop. Typically, for larger areas, the wider the cutting width, the better.

In addition, you'll want to look at both the max lawn area it can cut, and the runtime. The larger the area, the more grass it'll be able to cut, and the higher the runtime, the longer the mower will be able to cut for.

In terms of area, look for around 550 square metres or more - or one tennis court including the boundary lines - and for runtime, anything between one and two hours is considered great.

It's worth mentioning that some of these lawn mowers can be quite expensive, though, so if you're more concerned about affordability, it might be best to check out the best lawn mowers under 300 instead.

Frequently Asked Questions

Are robotic lawn mowers worth buying?

In short, yes. We'd say robotic lawn mowers are worth buying for the added convenience of not needing to mow the lawn, and they can also save on running costs compared to standard mowers, given they don't need to be plugged in and consume a lot of power in order to work.

If you want to reduce the maintenance of your lawn and still aren't sold on robot mowers, we've also looked into the artificial grass market to assist your lawn needs.

How many acres can a robot mower mow?

This all depends on the robotic mower itself, but our picks above can handle anything from around a quarter of an acre to three quarters.

There are industrial-level robotic mowers that can cut acres of grass in a sitting or have a max area of several acres, although these will be a lot more expensive.

How much does a robotic lawn mower cost?

Much like the question on acres, this depends on the mower. As a general rule though, ones for larger lawns will cost more - these can range from around $1000 to $5000 depending on the max lawn area, runtime, and features on offer.

Do robotic lawn mowers get stolen?

Robotic lawn mowers aren't often stolen because they come with an array of security features such as GPS tracking, phone alerts and loud alarms. Thieves are often inspired by opportunity, and these mowers don't give them a lot of that.
