Mammotion Luba Mini AWD 800

RRP: £1,499

Our rating: 5/5

Buy now from Mammotion

Pros

• Reliable and intelligent navigation
• Robust build quality and six cutting blades
• Powerful app with a huge range of features
• Whisper-quiet at less than 60 dB

Cons

• You need to be smartphone-savvy to get the most out of the mower
• Requires a GPS antenna with plenty of open sky
• The tiny safety key is easy to lose

This mower is a quite astonishing achievement, blending rugged all-wheel drive capability with a powerful app and tons of useful features. Decked out in all white, it looks rather like an off-road F1 car.

Setup is as easy as possible, with a detailed paper guide and help via the app. You just need to attach some components and plant the antennae in the ground. It doesn’t even need to be close to the charging base. The mower keeps in touch via WiFi, Bluetooth, and 4G connectivity.

Determining your lawn shapes means driving the mower around with your phone like a remote-control car. You demonstrate your no-go areas and channels between up to 20 lawns, and that’s about it. The Luba Mini AWD does the rest. It can even use AI to map out your garden all on its own, but that takes longer.

The most impressive thing about this mower is that it can go just about anywhere. It has four powered wheels rather than the standard two that you get on most robot mowers, so it's a solid choice if you have an uneven garden. It can climb steep slopes of up to 38.6° and turn on its own axis thanks to clever front “omni” wheels.

We were impressed by this mower's power and capability, as well as its ability to cut long grass when needed. Because of this, we have awarded the Luba Mini AWD a BBC Gardeners’ World Magazine Best Buy award for all-terrain mowing.

You can change mowing heights on the go from 20mm to 65 mm. The mower acts as a mobile security camera with its live video feed and can even draw pictures on your lawn in grass. This version can tackle lawns up to 800 m² and mow up to 250 m² per charge. Plus, it does it in neat, straight lines and performs a thorough perimeter cut. It even makes neat three-point turns at the end of a pass to protect the grass.

Another feature, and one that seems to have been missed on other mowers, is “manual mowing mode”. When you’re within Bluetooth range, you can drive the mower with your phone to tackle any awkward tufts of grass or missed spots.

The only downside of a feature-rich mower like this is that you must be confident with the app to get the most out of it. If you want something that is “set and forget”, you might find the Luba Mini AWD challenging.

The LUBA Mini AWD is the smaller of the two LUBA mowers in the range. The larger battery version can tackle lawns up to 1,500 m². Both come with a three-year warranty.

Stihl iMOW 5

RRP: £1,729

Our rating: 4.8/5

Buy now from a STIHL-approved dealer

Pros

• Easy to set up on the app
• Wide range of cutting heights and cuts even longer grass well
• Quiet
• Good features include rain sensor, anti-stuck and 40% slope capacity
• Long warranty

Cons

• Need to be tech/app savvy
• No mobile connectivity for the price
• Installation kit sold separately

The iMow 5 is the smallest in a new range of six robotic mowers from Stihl that cover three sizes of larger garden – 1500m2, 300m2 and 500m2. Together with the iMow 5,6, and 7, there is also the iMow EVO range, which covers the same size lawns with the same features but also has mobile connectivity, allowing you to connect to your mower even when you’re not at home.

When you purchase an iMow, you have the choice of installation by a Stihl-approved dealer (the cost of this will depend on the size of your garden), or installing it yourself and purchasing an additional installation kit.

To cut down on waste, different size installation kits are available and as well as the standard fixing pins which hold the wires in place, there’s also the option to purchase bio pins, made from 100% biodegradable material that gradually break down in the soil. Like many robotic mowers, the iMow requires a boundary wire around the perimeter of the lawn and a guide wire through the middle of the lawn to help it find its way back to the docking station.

The mower comes with a clear instruction booklet, plus there are helpful guides on the Stihl website if you need them, and laying the wires in our 1,250m² test garden took 3-4 hours. When laying the wires, it’s worth noting that the boundary wire needs to be 37cm from paths, a deck or fence, unless they’re level with the lawn, and then it can be right up against them and 100cm from a pond. You also need a clear 2m area straight in front of the docking station for the guide wire and 37cm on either side before you start laying the wires.

Once the wires are laid, it’s easy to programme the mower via its app, as long as you’re comfortable with this kind of tech. There’s no control panel as such on the new iMows, so there’s no need to bend over a control panel to set mowing times, heights and zones, etc. All of this is programmed through the My iMow app, which is pretty simple and intuitive to use, but only works via your own wifi at home, if it reaches into your garden, or by Bluetooth when you’re standing next to the mower. There are also four large control buttons on the mower that allow you to stop, start, unlock, and send the mower home without using the app, and an info button that talks to you and gives you status updates.

Like many other robotic mowers, the iMow has three free-swinging blades, and it cuts very well. The lawn was quite long before it was installed but with an impressively wide cutting height range of 20-60mm it didn’t struggle, and after a few days the whole lawn looked good with no tufts of uncut grass and it continues to look good.

Unlike the Husqvarna Automower, once you’ve laid the boundary wire, you can’t completely alter mowing zones and would have to lift and relay to change this, but you can divide your lawn into zones by directing the mower to only mow on one side of the guide wire. It cuts close to the edge, so there’s no need to tidy up afterwards, and if it comes across an obstacle, it gently bumps into it and then turns away. It also has a feature that helps it manoeuvre out of a situation. If it does get stuck, it can cope with slopes of 40%, has an anti-theft alarm and a rain sensor feature, which you can adjust to interrupt or not start mowing if it’s raining. You can choose what degree of rain you want it to mow in, and when the sensor on the top of the mower dries, it automatically begins mowing.

The iMow comes with a five-year warranty, and a host of accessories are available, including spare wire, pins and clips, a sun canopy for the docking station and upgrade wheels for the EVO range to enable them to cut slopes of up to 60%. For the size of larger lawn it cuts, this is a reasonably priced mower that’s packed with features and cuts very well.

We are particularly impressed with the range of cutting heights, its ability to cut longer grass and the simplicity of its design and awarded it a BBC Gardeners’’ World Magazine Best Buy for performance.

Segway Navimow i105E

RRP: £949

Our rating: 4.8/5

Buy now from Navimow

Pros

• At 58 dB, it’s almost silent when cutting
• More than enough cable to position the GPS antenna included
• The app offers live help and features
• Cuts in straight lines so fewer tufts are left behind

Cons

• The default light settings are far too bright
• You need to find a place for a large GPS antenna in your garden
• It makes a lot of unnecessary beeping noises until you turn them off

The latest addition to Navimow’s fleet of robot lawn mowers has built on the success of the previous H series. They’ve listened to criticism and tweaked this new mower to work better in the garden with easy setup and impressive features. Because of this, we've awarded the i105N a BBC Gardeners’ World Magazine Best Buy award for wire-free lawn mowing.

Not only is the GPS that helps guide it around the garden( the Exact Fusion Location System ) the upgraded 2.0 version, but its camera technology can detect and avoid all sorts of obstacles in the garden. It’s a simple addition, but you now get 20 metres of antenna and power cable, which makes placement of the GPS receiver much simpler, and all without the need to buy extra wires. The app can also help you find the ideal place to position both the GPS antenna and the charging station in your garden.
They’ve kept in our favourite features, like the brilliant app that lets you drive the mower around like a remote control car to define the shape of your lawn.

You can also watch the mower work in real time, and it lets you know immediately if there are any problems. The mower also checks the weather via the internet and adjusts the mowing program accordingly. The i105N model can happily cut moderate-sized gardens up to 500 m², and thanks to the large orange wheels with an aggressive tread pattern, it can cope with slopes up to 30%. The quality of cut is just as good as the previous mower, but now comes with a class-leading 20 - 60 mm range of cut depth. It still cuts the lawn in pleasing straight lines as well, which helps to avoid untouched tufts of grass.

Worx Landroid Vision L1300 WR213E

RRP: £2,199.99

Our rating: 4.5/5

Buy now from Amazon

Pros

• No boundary cable to install or GPS antennae to deal with
• Cuts as close to the boundary as possible with a robot mower
• It cuts lawns up to 1,300 m²
• You can control multiple Landroid mowers via the app

Cons

• A significant expense for a lawn mower

A rather astonishing leap forward in robotic mowing technology, the Worx Landroid mower does away with boundary cables and tricky GPS receivers and uses cameras and AI technology to mow your lawn instead. We awarded it a BBC Gardeners' World Magazine Best Buy for installation and features. This big and futuristic-looking mower is installed in seconds and connects to your phone or tablet via the Landroid app, although you can also control most of the functions via the onboard LCD screen and dial if you like. Using cameras rather than boundary wires, it knows where your lawn ends, keeps an eye out for obstacles, and even avoids hitting wildlife or pets. The cutting height ranges from 30 – 60mm, and you can adjust this via the app or the LCD screen, but the Landroid also self-levels the cutting deck to ensure that uneven ground is cut properly. The three blades underneath are offset, allowing the mower to cut close to the edge of hard boundaries, and big, knobbly wheels help the mower keep a good grip on slopes up to 35%. It cuts to an excellent finish, and after a few days of mowing, there are no tufts or patches of uncut grass. It creates its own mowing schedule to suit the time of year and uses a standard Worx battery that you might find on one of their drills or saws. Packed with features and clever technology, the only thing that might put you off is the price. However, it's capable of tackling huge gardens up to 1,300 m², so it’s ideal for very large lawns, and could even replace a ride-on lawnmower. The mower comes with a two-year warranty that can be extended to three years.

Husqvarna Automower 405X

RRP: From £1,849.00

Our rating: 4.5/5

Buy now from Husqvarna

Pros

• Unobtrusive colour
• Easy, mobile connectivity
• Clever mowing features
• GPS theft tracking

Cons

• High price
• Short warranty

Awarded a BBC Gardeners’ World Magazine Best Buy for features, the Automower 405x boasts a huge range of features that help the mower cut well and make the experience easy for the user. These include, three different start points, switching mowing pattern according to where it’s mowing, such as through a narrow passage, frost guard and weather time that automatically adjusts the height according to the grass growth, and its new Rewilding Zone where you can leave 10% of the lawn aside to grow for pollinators.

It's available to buy as a bare mower, which is then installed by a dealer for an additional cost, or with the installation kit included, and you install it yourself. Suitable for smaller gardens 600m2, the mower operates with both a boundary wire and a guide wire and, unlike some other mowers, has a more flexible docking station, which doesn’t need a wide, clear space around it - ours was tucked neatly into the side of a hedge. It’s also easy to set up via the intuitive keypad or the impressive Automower Connect app, which allows you to change the schedule, adjust the height of cut, check on the mower's progress and receive notifications, simply and quickly, no matter where you are.

As an X model, the mower also has a built-in SIM, so you have both remote- and voice-control. Our only confusion with the set-up was working out the scheduling needed, which took a couple of weeks to establish, and that the height of cut on the app is listed as 1-9, when it cuts between 20mm and 50mm.

The mower can cope with 40% slopes, which should suit most gardens. The slope in our test garden has a tendency to get muddy and slippery, so at the installer’s advice, we used the spiked Terrain wheels, which stop the wheels from slipping. Only occasionally did the mower fail to get up the slope, and when the weather was really wet, we removed that zone from the work area. The mower cuts consistently well and is very quiet; the only perceptible sound is the whirring of the blades as they cut. It occasionally missed spots on the lawn, but overall, this is a very easy-to-use and high-performing mower.

The Automower 405x is just one in a wide range of Husqvarna mowers to suit different-sized lawns. A host of accessories, including a docking station cover and wheel brushes, as well as spare parts, from batteries and blades to wheels, are also available. Both the mower and the battery come with a two-year warranty.

Flymo EasiLife Go 500

RRP: £689

Our rating: 4.3/5

Buy now from Amazon

Pros

• Incredibly quiet during use
• Small and easy to move around
• Supplied with plenty of boundary cable and spare connectors
• Spot mowing function for problem areas
• An affordable robotic mower for smaller gardens

Cons

• Installing the guide wire correctly can be tricky
• Lacks a screen
• Changing mowing height isn’t quick
• Setting multiple mowing zones takes a while

This compact yet capable little robotic lawnmower is an ideal choice for small to medium-sized gardens and we awarded it a BBC Gardeners’ World Magazine Best Buy for small gardens.

With more than half a century of experience in the garden, Flymo know a thing or two about mowing and their EasiLife Go 500 is marvellously small and lightweight and uses three pivoting blades for an even cut.

There's an online video to help with installation. You should watch it before you start, as the mower needs both a boundary wire and a guide wire pegged down. This can be a bit tricky, but it is easier if you plan ahead.

Unlike some mowers, instead of an LED screen, you get five buttons on the top of the mower that control all the basic functions. For everything else, there’s the Flymo EasiLife app. It’s easy enough to programme and cuts regular-shaped lawns with ease. It mows in a random pattern, so every piece of grass is cut eventually, but there’s also a spot mowing function if any are missed. You can also set the mower to cut different sections of your garden, including narrow passageways, although this is a bit fiddly to master.

The cutting height ranges from 20-50mm, and the wheels can cope with slopes up to 25% and a slightly bumpy terrain, but it’s much happier on flat lawns. Due to the small cutting width of just 16 cm, it’s only really suitable for small gardens up to 500 m². It’s one of the more affordable mowers in our test and comes with a two-year warranty.

Best of the rest

Although some models didn’t quite achieve a BBC Gardeners’ World Magazine Best Buy award, they still have great features that make them worth recommending. Browse our pick of the best of the rest robotic lawn mowers on test.

Stiga A4 Automatic Robot Lawn Mower

RRP: £999

Our rating: 4/5

Buy now from Stiga

Pros

• Reasonably priced mower
• Very quiet operation
• Intuitive in-app setup

Cons

• No camera technology for obstacle avoidance
• Lots of open space is required directly above the garage
• Short power cable

The Stiga A4 joins a long line of gardening equipment from the Italian brand, from big ride-on mowers to this fully automated lawn mowing machine designed to tackle lawns up to 400 m².

The A4 is smallest capacity in the range, the A8 has a larger battery and can mow lawns up to 800 m².

It features a pair of wheels at the back for the drive and another pair of shopping-trolley-type omnidirectional casters at the front. Four cutting blades, the height of which can be adjusted from 20-60mm via the app, are included. The mower can tackle slopes of up to 24°.

Several controls are under a flap on top of the mower body, and for security, a tiny key needs to be in place before any mowing can take place. The A4 uses GPS data to guide itself around the lawn. Lacking cameras to keep out of the way of obstacles, it gently bumps into stuff left on the lawn and then mows around them.

During setup, the app instructed us, via email, to begin digital mapping. Rather than via the app, it asked to use a laptop to define the lawn area. The Stiga Go app is easy to use and quite intuitive, so it was a surprise to be asked to use a laptop instead. The trick that Stiga have up their sleeve, though, is that you can use Google Maps’ satellite view to pre-draw the perimeter of your garden. If you have an ample space to mow, it’s actually a rather good idea.

To define lawn shapes, channels and no-go areas, you drive the mower around like a remote-controlled car. The robot then attempts the same path on its own, with you walking behind. This feature is nice because it provides a trial run before agreeing to a mowing or moving pattern. It’s just a shame that you can only set two different zones.

The garage also acts as the brains of the whole operation. Tucked inside is the GPS receiver, which is a neat use of space if you dislike a separate antenna setup. If you don’t like the idea of a separate antenna, you’ll like this approach. And because Stiga have developed a clever guidance system that uses multiple satellites to map out the garden space, it should work even when there are overhanging trees and other overhead obstacles.

However, the garage needs 120 degrees of open air above it to work correctly, which is tricky given that it only comes with a short 5m power cable. You can remove the GPS module and attach it to a wall or fence, but to do this, you'll need to buy an extra 15m extension cable and another power supply. Compared with the generous extra cable and power pack provided by the Mammotion Luba Mini AWD, it's disappointing that you can't always make it work with what comes in the box.

Even though the test garden we used had a tricky shape, the mower still installed itself and cut the lawn without much complaint. It could find itself on the lawn, get back to the charging station and cope with reasonable undulations without getting stuck.

The app is well thought through, and the setup guide is easy to follow. You can set schedules and add extra modes via the app to make cutting more efficient. Once it gets mowing, it's incredibly quiet at just 57 dB; the only sounds you can hear are the wheel motors gently turning and the sounds of grass blades being sliced by the four razor-sharp blades. It mows first in 18cm-wide parallel lines across the grass, then finishes things up with a neat perimeter cut.

Overall, this is a solid robot mower. It doesn't have some of the more advanced features of other mowers, but it's simple to install and leaves the grass well cut. It even does a decent job of defining borders.

The Stiga A4 comes with a three-year warranty.

Husqvarna Automower 405XE NERA

RRP: £2,398

Our rating: 4/5

Buy now from a Husqvarna dealer

Pros

• Cuts close to borders
• Impressive level of height- and lawn-pattern customisation

Cons

• Slightly confusing map setup
• No cameras for obstacle avoidance
• High price point

An undoubtedly handsome machine, the Husqvarna Automower 405XE NERA is a grown-up’s idea of what a robot mower should look like. Staying away from gaudy colours and concepts, this looks more like a sports car – with LED headlights and a price tag to match – driving across the lawn. It’s not just good-looking, though; it’s a robust and solidly built thing that can cut lawns up to 900 m².

Sitting in the middle of the NERA range, it’s the smallest-capacity mower that boasts 4G connectivity.

It works in two ways: either with a boundary wire that you sink into the ground around the edges of the lawn or with a clever satellite-guided module that eliminates wires altogether. The version we tested is the updated boundary wire-free offering.

The sat-nav module comes in a separate box; all you need to do is pop the top of the mower and screw it on. This upgraded ‘brain’ also uses 4G coverage to help pinpoint the mower and track it should someone steal it. The best thing is that you don’t need to install a fiddly antenna in your garden.

The drive comes from a pair of large wheels with deep treads on the front of the mower. The rear ones are a pair of shopping trolley-like castors that move in all directions. It can climb slopes of up to 30°, and running at just 60 dB, it’s a very quiet mower. It goes to bed in its garage, where it can fully charge in around 90 minutes before giving around 100 minutes of mowing time.

There's a handy little screen on the top of the mower that you navigate with a little wheel. It's an intuitive control, if you don't mind bending down to use it. From here, you can enter the security PIN and set the mower off to work if you don’t have your phone on you.

Something we found a bit trickier was setting up the map. Rather than simply driving around the edges of the lawn and leaving a perimeter trail, the 405XE NERA wants you to leave waypoints instead. They’re a bit of a fiddle and, although you can edit them afterwards, it doesn't feel intuitive.

A nice feature on the 405XE NERA is the second cutting deck slung underneath the mower. Positioned at the very rear of the mower, it gets as close to the edge as possible, which all but solves the robot mower problem of leaving the borders of the lawn ragged and untidy.

And the depth of customisation available is impressive. For example, you can choose a different mowing pattern, height and schedule for each zone. The mowing patterns include a random path to avoid tyre tracks, parallel lines, a chequerboard pattern and even a triangular pattern.

The app also lets you choose a security geofence that alerts you if the mower has been stolen, detailed mowing schedules or the option to let the mower decide when it is best to mow. You can also manually trim sections using the app.

Overall, this is a premium-priced mower that does a great job of cutting the lawn, once you’ve figured out its mapping quirks. It might lack a camera to help avoid objects like trees and discarded toys, but once it gets going, it leaves the grass looking neat and well-trimmed.

The Husqvarna Automower 405XE NERA comes with a standard two-year warranty that can be extended to three years.

Segway Navimow X350e

RRP: £3,199

Our rating: 4/5

Buy now from Ron Smith & Co

Pros

• Can mow lawns up to 5,000m²
• Six cutting blades and 21cm-wide cut
• Easy setup with lots of customisation available
• Mowing performance improves over time

Cons

• It's an expensive investment to make
• No first-person video option
• Struggles with some all-terrain challenges
• The orange plastic bumper is easily marked

Segway Navimow is no stranger to the robot lawnmower market, and the latest addition to its fleet is the X3 series. This one, the X350e, is a heavy-duty machine designed to replace a ride-on lawnmower, as it can tackle huge lawns up to 5,000m².

This model is part of Navimow’s X series of robot mowers, which also includes the huge 10,000 m² capacity X390e, the smaller X315 at 3,000 m² and the X330 at 1,500 m².

Bristling with cameras on three sides and finding its precise location with an antenna, the X350e uses AI to map out your lawn and avoid various garden obstructions. It's an impressive-looking beast, a large grey and orange robot with a large screen on the top that shows the mowing status in animations.

Setup is easy. After finding a place for the antenna to stick in the ground and connecting to WiFi, the rest can be done almost without user input. The AI-assisted mapping feature drives the mower about on its own to define lawn shapes, but it’s more fun driving it like a remote-control car instead.

The drive comes from two large orange wheels with an aggressive tread pattern. Unlike the Mammotion Luba AWD, the front two wheels are casters, similar to those found on a shopping trolley. This is common to most robot mowers, meaning that all the power is in the back, resulting in some wheel slip.

Navimow has employed a traction control system to help this mower tackle slopes of up to 24°. It works pretty well, but the mower still wasn’t happy on slippery surfaces like wet paving stones and slope edges.

Choosing mowing heights from 20-60mm, adding zones and paths between them, and even drawing pictures on your lawn is controlled by the powerful app. It gives you plenty of options, such as changing the direction of mowing and even changing the cut height of each zone. And it’s incredibly quiet at just 54 dB.

We found that the mower worked best on large, flat areas of grass. The wide cut and increased mowing speed made for fast work, but it avoided some weeds and patches of taller grass for some reason. The good thing is that you can use the manual mow feature to tidy up areas the robot misses.

Unfortunately for a mower that boasts an AI-enhanced camera, you can’t dial into a live feed on your phone. It’s a missed opportunity to double the X350e up as a mobile home security system.

Overall, Navimow have made another highly capable mower that does a great job on the lawn. However, for this price, we expected it to handle uneven gardens better without getting stuck.

The Navimow X350e comes with a three-year warranty.

RRP: £1,849

Our rating: 4/5

Buy now from Mowers Online and Felthorpe Lawnmower Services

Pros

• The quality of the cut is excellent
• It mows in pleasing straight lines rather than in random directions
• The app is powerful and fun to use
• No boundary wires to install

Cons

• Setting up the GPS receiver can be tricky
• You need clear space for the antennae to work properly

Once you get past the fiddly setup, the mower cuts your lawn in strips rather than in a random pattern, as well as offering spot cutting and boundary cutting modes. It cuts grass from 30 – 60 mm, the onboard camera helps to detect obstacles before it hits them, and it can tackle slopes up to 45%. It comes with a four-year warranty.

Pros

• Simple install with minimal tools
• Basic but easy to use app
• Generous amount of boundary wire included
• Wide range of cutting heights

Cons

• Only two cutting blades
• Multi area lawn is complicated to set up

Buy now from Just Lawnmowers

Pros

• Easy to programme
• Quiet, smooth & efficient
• Tackles large/sloping lawns
• Long warranty (during 2019)

Cons

• Relatively few features

A large capacity model, this robotic mower is smooth, quiet and easy to use. Out of all the mowers we tested, it can tackle the largest area and copes well with sloping lawns up to 45%. It’s smooth, quiet and unobtrusive. Its 360-degree sensors help it turn away when it comes near obstacles or pets, and the blades automatically stop when it's picked up. Clumps of lush grass are dealt with by the spiral cutting option, which mows round and round the grass until it's cut. However, it's the priciest option and has few features compared to other models.

How does a robotic lawn mower work?

Robotic lawn mowers are powered by rechargeable lithium-ion batteries and designed to cut the grass regularly, little and often, so the lawn always looks neat. Clippings are mulched back onto the grass, feeding the lawn, and there are no grass piles to deal with or collection bags to empty.

Most robotic lawn mowers work by detecting the edge of perimeters via sensors or a boundary wire. The latter is laid out around the edge of the lawn — as well as any obstacles such as trees or island flower beds — to tell the lawn mower to stay within that area. When the mower senses the boundary wire, it will change direction to avoid leaving the lawn. Many have collision sensors so that if they bump into an object, the robotic lawn mower will automatically turn around and head off in another direction.

Some models mow randomly, eventually covering the entire lawn before returning to the docking station. Others use a more sophisticated GPS system that allows you to programme specific paths. Robotic mowers are programmed with a pin pad on the front of the mower, but many models can also be controlled via an app, which allows you to monitor the mower's progress, schedule cutting times and let you know when servicing, etc, is required, easily and remotely. Once the mower has finished mowing, or if the battery is running low, the lawn mower will automatically return to its docking station, connect, and recharge.

These fully automatic mowers can save you hours of mowing time throughout the spring and summer, are great fun to watch and are emission-free. However, they are expensive, require an outside power source and careful installation, may not be appropriate for every style of garden and will not create stripes.

What are the benefits of a robotic lawn mower?

Buying a robotic lawn mower has several benefits over more traditional petrol or electric models.

These benefits include:

• Less work for you: Once installed and programmed, the robotic mower will automatically cut the grass according to your specific schedule. The lawn will always look tidy, and the mower will return to its dock on its own when it needs recharging.

• Zero emissions: Unlike petrol mowers, they emit no emissions because they’re powered by a rechargeable lithium-ion battery.

• Quiet: The lack of an engine also makes the mowers incredibly quiet.

How to choose the best robotic lawn mower

Price and size ranges for robotic lawn mowers

Robotic lawn mowers are expensive, especially when compared to cordless or electric lawn mowers. Prices start around £600 with premium models for large gardens costing anything from £3,000 up.

Most brands include a range of mowers to suit gardens of different sizes, from small 400m² lawns up to large gardens and estates up to 5,000m² in size and beyond.

Robotic lawn mower features

Beyond being fully automatic, the additional features on the best robot lawn mowers vary depending on the model. They can include weather sensors, GPS navigation and smart connectivity, which is increasingly popular and useful for making the mower easier to programme wherever you are. Readily available as an app on your mobile phone, you can adjust the schedule and set up your phone without having to bend over the mower’s PIN board, but you can also check on your robotic lawn mower while you’re away, track it if it’s stolen and see when it needs servicing.

Good security is essential when paying for a machine in this price range, and all mowers have security features as standard. Some simply require a PIN code to start the mower, while others have lift sensors, alarms and a GPS tracker.

The latest innovation in the robotic mower world is the arrival of a number of mowers that cut without the need for a boundary wire. Although some mowers could already do this, they were primarily for very large open lawns or small gardens with particular types of boundary, such as paving or raised beds. Now there are mowers that can identify exactly where they are, with the help of pinpoint positioning via GPS or are able to identify grass as well as other obstacles to work out where to mow.
We are currently testing some of these new mowers, so keep checking this page for updates and our latest reviews.

Robotic lawn mower requirements

Although they're fully automatic, once set up, robotic lawn mowers are more complex initially than traditional petrol, electric or cordless mowers.

A robotic lawn mower requires an outside power source to connect the docking station, and this ideally needs to be positioned out of direct sun and level. Most also need a clear area around them—typically two metres to the front and a metre each side—which can limit where you place the docking station, especially in a small garden.

Accessing the layout is also essential before purchasing a robotic lawn mower. Some models can struggle with narrow passages, uneven ground and steep slopes.

Finally, they need installation, and the boundary wire and sometimes a guide wire too, laid. You can either do this yourself, which takes time or get a dealer to do it for you, which is usually an additional cost, although some models include installation by a dealer in the price. They will assess your lawn, lay your boundary wire for you and show you how to programme and operate the keypad. If you're installing the mower yourself, take care to follow the instructions precisely for the robotic lawn mower to run correctly.

How to clean a robotic lawn mower

Despite being fully automated, a robotic lawn mower should still be checked, cleaned and serviced regularly.

• To clean, make sure the machine is switched off and turn it over to check the blades for damage. Clean the chassis and blades with a brush or a garden hose if dirt is more stubborn.
• Grass may need removing from the wheels and give the body a wipe down with a damp cloth.
• Blades should be able to pivot freely, and damaged blades should be replaced. All blades should be replaced at the same time to ensure a balanced cut.
• A service each year is encouraged so that dealers can update software. They will also clean and replace any worn parts, including batteries.

How we tested robotic lawn mowers

The BBC Gardeners' World Magazine reviews team tested a range of robotic lawn mowers for several weeks in different gardens. Some were installed for us by dealers while we installed the smaller mowers ourselves. They were programmed and left to work and were assessed according to the following criteria, with equal marks attributed to each:

• Set up and ease of use: Looked at installation and programming, including the need for a guide wire as well as a boundary wire, smart connectivity capacity and how easy it is to connect to the app.
• Cutting performance: Assessed how well it cuts the grass- the efficiency of cut and the neatness of the finish, its ability to evenly spread the cuttings and its ability to handle rough and damp grass. Also looked at run time, charge time, and noise.
• Features: Focused on how well the mower could cope with obstacles or handle slopes, the number of zones you can programme it to mow, rain or temperature sensors, security features, etc.
• Value for money: Considered all of the above, along with the length of warranty and price, including installation cost where applicable.

Top tips for lawn care

Here are some top tips for keeping your lawn looking fresh and healthy:

If your lawn is young, ensure it’s well-watered, but be careful not to overwater as this will cause the grass to root shallowly. Use rainwater if possible, or grey water from your bath or washing-up bowl. Sprinklers are effective but use lots of mains water. Don’t worry if your lawn is established and goes brown; it will green up again after some rain.

Weed your lawn – keep an eye out for plantains and dandelions which have wide, flat leaves, and can smother large areas. Remove with a hand trowel or daisy grubber. Avoid weedkiller if possible. Find out more about weeds.

Compacted ground can prevent grass from growing well, and lead to bare patches or muddy spots. Relieve compaction and aerate the soil with a garden fork, pushing it about 10cm deep every 10cm, and gently rocking back and forth on the fork handle. Take a look at our pick of the best lawn aerators and the best scarifiers.

Edge your lawn for a neat finish; this satisfying job can be carried out with long-handled shears. It will also stop grass from growing in your borders. See our review of edging shears.

You might also like to keep edges neat with a physical border. Take a look at our picks.
