3 Best Robot Mowers for Large Lawns (1+ Acre)

Sizzling BBQ, sunscreen and the smell of freshly cut grass—ahhh, the aromas of summer months. But a nice-looking lawn takes maintenance, and this takes time. If you have a large yard and like to entertain, mowing your lawn may not fit into your schedule. So, how do you get that crisp green smell without the time commitment? Let a robot do the work for you.

Like a robot vacuum, a robot lawn mower works in a similar way; it moves around a lawn in a random or preset pattern and clips grass that’s longer than the target length. The best way to use a robotic mower is to cut the grass more frequently—a little at a time—so the tiny clippings fall into the lawn and fertilize the soil, rather than sit on top of the grass. Regardless of the mower, each one requires a setup. If your model uses a guide wire, you must place the boundary wire around the perimeter of your lawn. If it is wireless, you must a GPS enables app to draw the virtual boundary. This will guide the mower on how far to go and where to stop—much like an invisible fence.

In addition to saving you time, other advantages of robotic mowers are:

  • Battery operated; less polluting
  • Quiet, compared to traditional mowers
  • Independent with minimal human involvement; automatic return to base, app-enabled cutting schedule
  • Safe; blades stop if mower is lifted, pin code and alarm help prevent theft
  • Convenient; the tiny clippings that fertilize the soil don’t require picking/bagging
  • Weather resistant; can work during rain and hot weather (you may not want to). It’s best, however, to cut dry grass. Most robotic mowers have rain sensors and delay cutting until the rain stops

Ambrogio Robot Mower Mows Lawns up to 5 Acres

Robot mowers have improved considerably recently. Most notably Ambrogio has developed the model L400I Deluxe, a powerful robot with an attractive design typical of Italian products, which can manage lawns up to 5 acres! The model is also equipped with the ZCS Connect module so you can connect and interact with Ambrogio any time and anywhere.

We have been working with robot lawn mowers for many years now. We’ve tried a wide variety of brands and models, and the best ones we’ve come across for large lawns come from Husqvarna, Mammotion, and Ambrogio.

Husqvarna Automower 550

At a glance

Sweden-based Husqvarna made its first robotic mower in 1995. This unparalleled experience helps the company produce a quality robotic mower and improve on it as technology advances. Of the four featured mowers, the Automower® can cover the most space—up to 1.24 acres. But its standout skills may be the ones that have been patented:

  • GPS-assisted navigation to map the yard and configure which parts of the lawn it has covered. It then adjusts the mowing pattern to ensure optimal coverage
  • Triple guide wires to reduce searching time
  • PARK button on charge station to call back the mower at any time
  • Electric height adjustment to change the cutting height as needed
  • Automatic passage handling to sense narrow paths and finds its way even through the smallest spaces

To create a beautifully cut lawn, the Automower uses a free movement pattern that creates a carpet-like look, it has sharp carbon steel blades and an automatic cutting functionality, which reduces grass height differences.

Mammotion Luba

The LUBA robot mower is a product from Mammotion, a company dedicated to creating cutting-edge electric autonomous lawn mowers. The team’s staff comes from some of the world’s leading robotic companies, with experience in creating and perfecting autonomous driving algorithm technology, sensor fusion, and mechanical control.

Unlike other robotic lawn mowers, there’s no need to find a shovel to bury any perimeter wires. All you need to do is open the app and walk along the boundaries of your lawn with your mower. You only need to do this when you are establishing a new zone. It can mow lawns up to 1.25 acres.

The LUBA mower uses the highly sensitive real-time kinematic (RTK) technique to keep the mower within the precise boundaries you establish on setup. The special RTK antenna and reference station mean that your mower will know exactly where to go, even with a weak satellite signal.

Robot Mowers Can Handle Large Lawns

The first generation of robot mowers were more like a novelty and could really only handle small lawns up to 1/2 acre or so. But with improved batteries, guidance technology, and programming, newer mower models can easily handle lawns of an acre up to 5 acres. So don’t let having a large lawn prevent you from enjoying all of the benefits that automated mowers have to offer.
