The best robot lawn mowers will make your life a breeze. If you’re someone who doesn’t like gardening or simply doesn’t know where to begin, then let a robot do it for you!

While you have to take some time to set up its perimeter before the first run, once that’s done, away you go! Simple as that, just let it work it’s magic.

Robot mowers are a little bit more pricey than your average lawn mower – so if you’re on a budget you may prefer to look at the best small lawn mowers, the best cordless lawn mowers or even the best petrol lawn mowers.

However, a robot mower can be significantly cheaper than hiring a gardener in the long run!

So while your bot is keeping your lawn looking lush, you can sit back, relax and enjoy the best barbecues or best pizza ovens in the summer sunshine.

Check out our round up below to find the best robot lawn mower for you.

Requires a decent wi-fi signal

The Worx Landroid M500 Plus is a sleek orange stunner which unsurprisingly, is Europe’s biggest selling robot mower. After all, for a lawn bot that costs under £700, the stupendously named Landroid is as sci-fi as it comes.

Uneven lawns are no bother for this bot because it uses advanced inertia sensing technology to gauge inclination (up to 35˚), wheel drift, speed and torque. It’s fully waterproof too but will cleverly refuse to venture onto the lawn if it’s been raining and the lawn is wet. It’ll even avoid going out at night in case nocturnal hedgehogs are rummaging about on the lawn, though this can be disabled in the accompanying wi-fi app. Just be sure you have a decent wi-fi signal in the garden because a handful of users have reported the odd connection issue.

Once the perimeter wire and near-invisible charging station is installed – preferably by an expert – the Landroid M500 Plus can be left to its own devices. As is the case with all robot mowers, it’ll take several cutting sessions for the lawn to start looking swanky. But from thereon in, it’ll remain in tip top condition every day of the year.

The Landroid M500 Plus is equipped with three offset pivoting razor blades for edge cutting and it has a mowing width of 18cm, so it’s good for lawns up to a maximum of 500 square metres with slopes not exceeding 35%.

If you’re planning on jumping onto the robot mowing bandwagon, then this mid-sized model in an absolute kingpin that not only performs well but looks the business, too. But if you have a smaller lawn, perhaps consider the Worx Landroid S300 instead.

The Worx Landroid M500 Plus has won the Best Robot Lawnmower award at the T3 Awards 2022. These are the reasons the judges selected it.

Not ideal for gardens over 250m sq

Most people have medium-size or small gardens, and that is who this smart, compact robot lawn mower from Flymo is targeted at. It cuts lawns up to 250 square metres in size, with its intelligent guide wire allowing its owner to specify cutting areas (multiple ones, even).

Cutting width is a modest 16cm, which isn't huge, but again this mower isn't designed to cover really large areas. The Flymo EasiLife 250 Go does come with a pivoting three razor blade cutting system, though, and that operates at a very ear friendly 58 decibels, so you're definitely not going to annoy your neighbours.

A key selling point to this model is how easy it is to use, with a small selection of top-mounted buttons making it easy to stop and start. The beauty, though, is that the EasiLife 250 also has its own Bluetooth-connecting app, which unlocks the mower's full menu system, offering access to scheduling, trouble shooting and extended settings.

The Flymo EasiLife 250 also comes with a charging base that has been designed to sit anywhere around a lawn's edge, including corners. It also features LawnSense and FrostSense sensors, which allow the mower to automatically adapt its mowing schedule according to the weather.

The EasiLife 250 can cut slopes up to 14 degrees, which again is not really high and beaten by other mowers in this guide, but providing your lawn is remotely flat then that won't be a problem. Overall, this is a quality compact robot lawn mower for small to medium gardens at a competitive price point and with a strong all-round package.

Is your lawn 700m sq?
-
Expensive

This brushless motor model from the house of Bosch is another ideal option for small urban lawns. Once set up, its intelligent LogiCut navigation system calculates the most efficient mowing pattern before setting off on its first cut.

Unlike many robotic mowers that adopt a zigzag pattern, this one is said to cut lawns using a diagonal up-and-down method. This means that the patterns on your lawn during the first few cuts won’t look quite so irregular. SpotMo is another cool feature that enables the Indego to mow small patches of growth under tables and other garden furniture (obviously you’ll need to move the furniture to the side first).

As is the case with many robotic lawn mowers, this one monitors weather forecasts and only ventures out when it’s mostly dry – a good thing because wet grass rarely cuts well. It can also be controlled via the Bosch Smart Garden app and Amazon Alexa.

The Indego M+700 has one of the smallest cutting decks here (just 19cm) so make sure your lawn isn’t larger than the stated 700 square metres. That said, if your patch does meet the correct dimensions and it doesn’t have inclines steeper than 27%, then the Indego is definitely worth a punt.

To see how this model stacks up against our number one choice, be sure to take a read of our Robomow RC 308u vs Bosch Indego M+ 700 (opens in new tab) comparison feature.

Not ideal for very large gardens

If you're looking for maximum bang for your buck, the Lawnmaster L10 is a great, affordable choice for lawns up to 400m sq. It chimes in for hundreds less than some of the other mowers in this guide and delivers strong performance for small and medium size lawn owners.

Caveats to an instant purchase include its small cutting width, which is beaten elsewhere, as well as the fact that its base station cannot be placed in a corner, which restricts placement options. There's also no smart connectivity features or smartphone app. However, everything else about the L10 point to a budget bargain.

The L10 can run for 40 minutes on a single charge and, once it automatically returns to its base station, it only needs 45 minutes to recharge back to full power. This means it is more than capable of multiple cutting runs over a half day period.

It offers cutting heights of between 20-60mm as well, with a three pivoting razer blade cutting system slicing the sward while outputting only 62dB in noise. The L10 is also IPX5 rated, which means it is fully waterproof – it even features an automatic return to base function if heavy rain is detected. Also, unlike some cheaper robot lawn mowers the L10 can deal with gradients of up to 35 per cent, so even if your lawn isn't perfectly flat it can deal with it without getting stuck.

Overall, the Lawnmaster L10 delivers a lot of performance for a low price point, so unless you need a bigger, more heavy duty robot lawn mower, or smart functionality, it's a strong choice.

Not suited to medium-big lawns

There’s a good argument for getting a Honda robotic mower. After all, the company has been at the forefront of the garden robotics industry for many years and we all know about Honda’s excellent reliability record in all matters mechanical. If its humanoid robot Asimo can walk, dance, kick a football, interact and carry things, it’s probably safe to say the company’s Miimo 40 will cut a lawn reliably and with very little fuss.

The Honda Miimo 40 Live is designed for small urban gardens up to 400m2 and has a cutting width of 19cm and an 18v lithium battery that provides up to 45 minutes of cutting time per 45-minute charge. Some of its features include the ability to handle inclines of up to 27%, monitor the weather via MeteoGroup before heading out on a cutting session, and even be controlled using the Mii-Monitor 40 app and Amazon’s Alexa.

As with all robotic mowers, it’ll take about a week or so before you’ll see the fruits of its labours but, before long, your lawn will look spick and span without you so much as having lifted a finger. For best results – and fewer back problems – get Honda’s installation team to set it all up for you. Top dollar cutting from a highly reliable brand.

Only operates within a single zone

Ideal for small to medium size lawns of up to 1,000 square metres, the McCulloch ROB 1000 isn’t particularly flashy or feature-packed, but it performs all the usual robot lawn mower duties – automatically mowing the lawn within its boundary wire, according to the times and dates you've programmed into it, and returning to its docking station to recharge when its battery gets low. It also includes an audible alarm and PIN protection to help protect it against theft. And it can handle inclines of up to 25% – handy for sloping gardens.

The McCulloch ROB R1000's biggest catch? It can only mow within a single zone (that is a front or back lawn). Many of its rivals can handle multiple zones, enabling the whole garden to be mowed.

Narrow cutting width

If you’re a busy city-dwelling bod with a small garden up to 250 metres square, this affordable 16cm ‘city’ model could just be the answer to your overgrowing sward conundrum. The Sileno City’s Lithium battery provides a continuous cutting time of 65 minutes before the mower heads back to its base station for a nifty 60-minute top-up. It’s quiet, too, and water resistant against both heavy rain and blasts with a hosepipe.

As is the case with most robot mowers, you’re advised to remove any raised garden borders or the mower will stop an inch or two from the flowerbed, leaving an unsightly strip of overgrown grass, to which you’ll then have to take a strimmer. Also, make sure your garden isn’t too hilly because this mower’s maximum inclination is a not especially impressive 25%.

The Sileno City cuts very well, albeit slowly, and is very adept at negotiating tight turns in confined areas. The bubble-type keypad interface is relatively easy to use too (it comes with its own onboard programming assistant), but those with poorer eyesight might have trouble reading the LCD screen in bright sunlight.

Of course, there is a good argument against having an expensive robot mower that cuts such a small area – after all, it wouldn’t be that much of an inconvenience to get off one’s posterior and have a quick 10-minute whizz with a cheap cordless or electric model. But that’s your prerogative.

Too much mower for many

The Smart Sileno+ is part of Gardena’s smart system range, which includes things like electronic timers and automatic garden sprinklers. That’s handy because the devices not only talk to each other when connected to a gateway via your home router, they also have internet access as well – and that means you can control them remotely using the free Gardena smart system app for iOS and Android. Clever. 

In practice this means that the Gardena Smart Sileno+ robot mower knows only to mow the garden when the garden sprinkler isn’t working. This model also includes Gardena’s SensorCut System, which effectively measures the height of the grass so it only cuts your lawn when necessary. Anything else? Unlike less capable mowers, Gardena Smart Sileno+ can handle complex, sloping lawns with inclines of up to 35% and can navigate even narrow areas with ease.

John Deere makes some of the most reliable utility equipment around – ask any farmer –  and the Tango E5 Series II is no exception. It works in any weather condition across almost any terrain and does so quickly and extremely quietly. Oh, and it has a range of up to 2,250 square meters.

Of course, lots of other mowers do that, too, but the Tango E5 is famous for its star-shaped blade design and quality, which John Deere is proud to talk about. Obstacles, like rocks, are protected against, which reduces the need to replace the blades or make repairs to the mower. The focus on blades may seem trivial, but it's something that makes the Tango E5 one of the better robotic lawn mowers around.

It’s bloody expensive

Sweden’s Husqvarna enters the robomow fray with a sterling model that looks like it could traverse the Alps let alone a Surrey lawn. We may as well get the price out of the way first so you don’t waste your time reading about a lawn mower that costs a shade over four grand – or £4,144 with large installation kit, to be precise.

The Automower 435X features a pivoting body that gives it exceptional manoeuvrability along with all-wheel drive to power its chunky off-road tyres over lumpy terrain and up inclines of up to a world beating 70% (roughly the same as a ski jump).

The Husky’s 22cm blade and 100 continuous minute running time make it ideal for massive lawns up to 3,500 square meters while its modest decibel count of 62dB ensures it doesn’t disturb the owls while out on a night prowl. It has headlights, too, presumably so the wealthy owner can look out from his man-study and watch its silhouette trundle across his might sward while sipping on a G&T.

The 435X uses GPS-assisted navigation to work out which parts of the lawn have been mowed. The sophisticated Automaker Access software then calibrates the mowing pattern accordingly, and tells you all about it via your mobile device. It also supports voice control using Amazon Alexa and Google Home.

For this kind of outlay you might reasonably expect it not to require any buried boundary guide wires but that’s sadly not the case. Hence you can safely anticipate forking out another chunk on having the whole shebang installed by a pro. Or do it yourself – if you have a few days to spare.

How to choose the best robot lawn mower

Getting every piece of grass an even length, making sure that every area is covered, and so on can be annoying, and that's not to mention inclement weather conditions. As the name suggests, robotic lawn mowers are just that. They happily move around a garden, cutting grass to an equal length and navigating most tricky terrain while you kick back and relax.

Depending on your garden type, different mowers can work better than others – for example, if you have a MASSIVE garden you'll want a large lawn mower with plenty of battery life, and if you have a small-but-hilly garden you'll need a mower with grippy wheels and plenty of power to negotiate inclines. Blade width is important, as are other features, such as the ability to remote control the mower with your smartphone.

However, you can't just buy a robotic mower, unbox it, stick it on the lawn and expect it to start cutting immediately because it needs a perimeter wire inserted around the entire lawn (preferably under it) and any obstacles like trees, benches, gazebos and arbours. The perimeter wire is a vital component that tells the mower when it's reached the edge so it doesn't run riot through the roses or tumble into a void. Instead, it'll turn around and mow somewhere else. 

You might also need to be mindful of natural obstacles like pine cones, beech nuts and dropped fruit. Most robot mowers will happily run slipshod over these types of small obstacles but to help prevent wear on the cutting mechanism, it’s advisable to clear most obstacles of this nature when possible. 

Another more pressing concern is dog poop because most robot mowers will simply ride over it, their blades cutting it into little bits which will naturally be spread around. If you don’t fancy the idea of your robot mower’s underside looking like a cess pit, then remove dog poop where possible or don’t get a robot mower. The good news is it will eventually decomposes naturally leaving no signs behind so it shouldn't be an issue after a while. Out of sight, out of mind.

Another thing worth noting is that robotic mowers tend to travel in a haphazard fashion that may make you wonder if you've bought a duffer. You haven't, it knows exactly where it's been and where it's going. So, bear with the zigzag patterns on your lawn for the first few days and eventually the whole sward will look evenly mowed and as smooth as a billiard table.
