Designed for smaller gardens, Flymo's EasiLife 150 GO is a compact robotic lawn mower that can automatically cut up to a 150-square-metre area of grass. Once set up, you can use the companion smartphone app to control this mower, giving you a completely hands-free way to manage your lawn.

LawnMaster L12 Robotic Lawnmower - Fully Automatic Robot MowerLawnMaster

The LawnMaster L12 is basically the big brother of our best overall robot lawn mower choice, the LawnMaster L10. While we love the L10 for the average-sized lawn, the L12 can cope with larger spaces, capable of mowing lawns of up to 800 square metres.

This durable robo-mower is IPX5-rated so can withstand a spot of rain, can cut at different heights from 20mm to 60mm, and has a mulching function to spread the grass cuttings evenly around your lawn to save you from having to dispose of them.

We rate this mower for "complex" gardens thanks to its "Multi-Area" function. This means that this lawn mower can not only start from the charging station but can also start regularly at specially defined points of the boundary wire in the garden.

We're highlighting this mower for its iRadar functionality. This is made up of two "Active Safety Ultrasonic Sensors" found on the top of the mower which means this is particularly adept at avoiding obstacles on your lawn - worth noting if you have cats, or kids that are likely to abandon toys in the grass. Sensors will also kick in if this mower is lifted or tilted in any way.

From a grass-cutting perspective, this has a 16cm cutting width, the ability to cut from 20mm to 55, mulching capabilities, and a handy rain sensor to send it back to base when the heavens open.

Pros

  • Packed with six different sensors for safe, hands-free operation

Best for lawns with hard borders

Lawnmaster robot mower Lawnmaster/Cleva

This is another choice suited to smaller gardens. Unlike many other robotic mowers, this is a particularly convenient option as it needs no boundary wire set-up. This is because it uses a grass recognition camera and ultrasonic sensors to mow your lawn, but it will only work successfully on lawns with hard borders such as gravel, paving, decking, or raised edges such as sleepers and fences.

This comes with a fast, one-hour charger. On full charge, this will mow a lawn of up to 100 square metres in a random pattern for up to four hours. As it mows, this drops the grass clippings on the lawn to help feed the grass. You can choose from cutting heights of between 20mm and 60mm.

Reviewers praise this for being a simple "drop and go" robotic lawn mower that needs minimal set-up, very little ongoing maintenance, and app-free operation to keep their smaller lawns looked after.

Pros

  • Fast charge functionality in around one hour
  • Manageable to handle at only 6.6 kilograms
  • Five different cutting heights to suit your needs

Cons

  • Needs a hard border to work

FAQs

What do I look for when choosing a robot lawn mower?

When you’re making a purchase of this size, it’s great to weigh up your options and reflect on your needs. Luckily, Geoff and Jill have thought this through and given us some help on what you need to consider when choosing a budget robot lawn mower to care for your lawn.
Lawn size
As you may have realised, robot mowers have a “maximum lawn size that they can cut without having to continually recharge,” says Geoff and Jill. What is our advice? Well, that’s easy: measure your lawn and ensure that you order the correct mower with enough supplied perimeter wire.
Lawn finish
Different blades will garner different results. A speedy blade with cut finely, whereas a double-bladed model will chop the grass into a finer, mulch-like cut. Our experts recommend checking “to see what grass-cutting height options are available.” Most models will offer heights of 3 to 6 cm.
Lawn shape and style
This may differ depending on which budget robot lawn mower you finally opt for. After all, some mowers can handle “sharp angels and oddly shaped nooks and crannies,” and others will not. For this, read customer reviews and expect a near-perfect result with a budget buy.
Slopes
Luckily, most models will be able to cope with a gentle incline, says Jill and Geoff. However, if your lawn “steeply slopes, some models will happily tackle angles of up to 45°.” To ensure you’re picking the correct robot lawnmower for the incline of your space, we’ve included slope capabilities.
Obstacles
You’ll be required to move things around for your new piece of kit. After all, you don’t want your precious new mower to face any problems along the way. For hard-to-move obstacles like statues, we recommend a model that uses a virtual boundary or sensors instead of a perimeter wire.
Run time
Generally, most lithium-ion battery-powered models will “give 45-60 mins of cutting time from each full charge, in as little as 30 mins.” Handy, right? Run-time can be determined by the output and power of the battery, also. Some robot mowers even remember where they left off before charging.
Rainy days
Budget options tend not to be able to cut grass in wet conditions. On the other hand, the higher-grade models are more likely to have this capability. Plus, some models have “a rain sensor and return to their dock when the rain starts falling, and resume when it stops,” says Geoff and Jill.
Lawn use
This goes without saying: keep your pets away from the garden when in use. Or, on the other hand, consider a model with an “obstacle sensor” if the pets and wildlife are free to roam your space.
Noise level
Importantly, we don’t want to annoy the neighbours. There’s nothing worse than waking up early on a Sunday morning to a lawn mower blaring outside your window. Luckily, some of the newer models “are incredibly quiet, emitting nothing more than a satisfying hum,” says Geoff and Jill.
Security
Gone are the days of mower theft. Some higher-tech models come with built-in anti-theft measures, says Geoff and Jill. Handy, right? They add: “These include alarms if the mower is moved outside of its perimeter boundary, security sensors, PIN codes and GPS tracking to monitor its location.”

How do robot lawn mowers work?

Thanks to Jill and Geoff, we can answer this question in detail:
According to the pair, robot lawn mowers are powered by rechargeable batteries, usually lithium-ion), and “use a charging station, dock or home that it returns to once it’s finished cutting or the battery is depleted and needs recharging.” However, the charging port requires mains power. They add that you need to set up this mower “within reach of a weatherproof power outlet.”
Despite this, Geoff and Jill agree that the robot lawn mower is an easy piece of kit to set up. This will be influenced by “the size and shape of your lawn and whether there are any obstacles to manoeuvre around”, though. Luckily, most mowers work within an electronic perimeter wire, which will orientate and guide the mower, laid “around the lawn edge just under the surface of the turf.”
Often, when approaching set-up, you may be greeted with something user-friendly – and some models have smartphone connectivity capabilities, working with an app or Alexa. These features may come in handy, coming in the form of “status updates, such as whether the mower is charging or cutting, even when you’re away from home”. These features are less likely with budget models.

Are robot lawn mowers any good?

Well, for a fantastic piece of technology, we can’t deny that there are a few drawbacks. Nothing is perfect, after all. So, to give you a better insight into robot lawn mowers, we’ve enlisted the help of My Robot Mower to speak about the pros and cons of these high-tech garden maintenance devices.
Pros:
You’ll never have to cut your lawn again. Just imagine your free time. When we have busy lifestyles, it’s hard to fit in tasks that’ll take a decent chunk of your afternoon. Well, no more.
Your lawn will look better. With a robot mower, you can regularly cut the grass and some models mulch the clippings, returning them to the lawn, which provides “nutrients to the growing grass.”
They are much safer. My Robot Mower claims: “Safety features of robot lawn mowers far surpass conventional mowers.” After all, there is no user interaction and sensors will prevent any accidents.
They can work out cheaper. Though a teeth-gritting investment, robot mowers can work out cheaper in the long run, due to “decreased maintenance requirements and lower operating costs.”
They’re great fun. Though not a practical element to consider, My Robot Mower explains that it provides a great conversation topic and the free time provides “a continued sense of satisfaction.”
Cons:
You need to install a perimeter wire. Most models use these to mark the edge of your lawn. Unfortunately, this is an unavoidable, manual task. So, installation can take a little while.
The edges of your lawn won’t be perfect. Yes- it’s true. Most models may leave some grass at the edge of your lawn, says My Robot Mower. So, we recommend tidying up with an electric strimmer.
The upfront cost is higher. As mentioned above, the robot mower is an investment. They can range from £300 and climb all the way up to an eye-watering £3000. However, it can work out cheaper.
Limited battery life. This is another gripe we have with these mowers. As they are powered by batteries, they need charging, so a sweep of a larger lawn may take a little longer than expected.
