Robot lawn mowers: comparisons, reviews and maintenance

Robot Lawn Mowers

A well-chosen, well-installed robot lawn mower turns lawn maintenance into something you don't have to think about: it cuts a little every day, mulches constantly (fine clippings feed the lawn) and keeps it at the same height, dense and without "rows". The result is usually a nicer lawn than with manual mowing, and several free hours a week.

In this section you have the 2026 robot lawn mower comparison by area, slope and features; the difference between models with a boundary wire (cheaper and proven) and wire-free ones with GPS/RTK or vision navigation; an in-depth review of the Husqvarna Automower 430X after a full season of real use; a step-by-step installation guide; and the debate of whether a robot beats a manual mower depending on the size and shape of your garden.

The points that matter most when choosing: the real maximum area and slope (not the brochure figures), whether your garden has separate zones or narrow passages, the noise level if the robot works during the day, the availability of spares (blades, wire) and manufacturer support. To get the most out of it, the lawn needs to be well cared for to begin with: see the guide on how to care for your lawn.

Frequently asked questions

How much does a robot lawn mower cost?

From around 300-400 for gardens up to 400-500 m² with a boundary wire, between 500 and 900 for 500-1,000 m² or models with an app and sensors, and from 700 to 2,000 or more for wire-free models with GPS/RTK or vision, and for large areas or steep slopes.

Robot mower with a boundary wire or wire-free?

With a boundary wire: cheaper, proven and reliable technology, but you have to install and bury a wire around the whole perimeter. Wire-free (GPS/RTK or vision): much faster installation and no wire to break, but more expensive and a bit more sensitive to obstacles, dense trees or poor signal coverage. For most medium gardens, the wire is still the safest option.

Can you leave a robot mower running when it rains?

Most are water-resistant and can work in the rain, but cutting wet grass clogs the blades, leaves marks and can encourage fungi. Ideally, set the robot to pause in the rain (many have a sensor or connect to the weather via app) and work when the grass is dry.

Is a robot mower dangerous for children or pets?

The blades are small, sit under the chassis and stop when the robot is lifted or tilted; they also detect obstacles and brake. Even so, it shouldn't run with small children playing on the lawn unsupervised, and it's best to schedule it to avoid the hours the garden is in use.

What maintenance does a robot mower need?

Changing the blades every 1-3 months depending on use (they're cheap), cleaning the chassis and wheel area every few weeks, checking the boundary wire in spring, and storing the robot and its base under cover in winter in frost-prone climates. The battery usually lasts 3-5 years.

Does a robot mower work for any garden shape?

It works well in single-zone gardens or with passages at least 60-70 cm wide. Very fragmented gardens, with many beds, steps or areas separated by paths, need guide modules or splitting the job, and some budget models don't cover them well. Check your garden's shape before buying.
