10 best robot lawnmowers 2017

Top tech-packed cutting machines to groom your garden while you laze around in the summer sun

TODO alt text

Mowing the lawn can be an arduous task. Luckily, modern tech companies have noticed the problems that mowing a garden can present and have come up with a nifty solution: the robotic lawnmower.

If you just want an instant recommendation, we consider the Robomow RS635 the best robot lawnmower on the market right now. 

It sports a robust build, can tackle any slope up to 36 percent and packs really big blades that can slice through rough grass with ease. Want more options? Then read on.

How to choose the best robot lawnmower for you

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 lawnmowers are just that. They happily move around a garden, cutting grass to an equal length and navigating 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 lawnmower with plenty of battery life, and if you have a small-but-hilly garden you'll need a mower with plenty of power and grippy wheels. 

Blade width is important, as are other features, such as the ability to remote control the mower with your smartphone.

The Robomow RS635 is best for big gardens with hard-to-reach or rough grass.

According to Robomow, the RS635 can handle grass that is up to 80mm long.

The RS635 is expensive, but its ability to scale 20 degree slopes, battery life that lasts up to 100 minutes, and low noise level make it the ideal purchase for anyone looking at the top-end of robotic lawnmowers.

According to the company, the 1200 R has a blade design that is specifically designed to reduce mess which, when coupled to the excellent range – 400 square meters – makes for a very useful machine that just gets the job done.

The mower is exceptionally quiet, at just 58 db(A), which is roughly the same volume as a spoken conversation.

John Deere makes some of the most reliable utility equipment around – and the Tango E5 Series II is no exception. It works in any weather condition across almost any terrain and does so quickly and 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 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 its something that makes the Tango E5 Series II into one of the best robotic lawnmowers around and, as you will discover, can save an awful lot of time and energy.

Bosch has excelled itself with the Indego 400 Connect, a mower that employs several cunning techniques to make sure the lawn is perfect.

The first technique is parallel blades, that cut the grass simultaneously to avoid missing sections. This ensures that every inch of grass that needs to be cut is. The second technique is clever: Bosch has programmed the Indego 400 Connect to start mowing at different points throughout the lawn every time, which reduces the risk of over-mowing a certain section.

The clever technology doesn't stop there, however. The mower comes with a smartphone app, to help track its progress throughout the garden.

5. Viking iMow MI 422P

A cut above the automated bunch

Reasons to buy
+Ease of installation+Siren that sounds just before cutting
Reasons to avoid
-Slow startup of the screen
Today's best deals

The green colour might not be to everyone’s taste, but it suits a garden. The control display isn’t great, but the charging dock is stable, and the iMow gives the cutest little wiggle before it plugs itself in. Underneath, there’s a blade much like a traditional lawnmower’s, 20cm wide and well recessed for safety. A rain sensor stops it going to work when it’s wet, but it will make up the time later. Installation involves laying a boundary wire around your lawn and connecting the charging dock to a suitable power supply. You set working hours using the display and small array of keys, then leave it to do its thing unbothered.

6. Worx Landroid M 800

Compact robot mower for medium-sized lawns

Specifications
Mowing width: 18cm
Mowing height: 20-60mm
Maximum lawn area: 800m sq
Slopes: 35%
Battery type: 28v lithium
Charge time: 90 mins
Average runtime: not stated
Coverage per charge: not stated
Noise level: 63db
Dimensions: 55x37x26cm
Weight: 8.9kg
Reasons to buy
+Ideal for medium sized gardens+Clever routing tech
Reasons to avoid
-Can take a while to set up correctly-Doesn't always cut to the edges

The mid-range robot lawnmower is ideal for lawns of up to 800m square, enabling you to laze in the garden at the weekend, while it does all the work.

The Worx Landroid M 800 needs a bit of setting up initially as you run its boundary wires around the edges of your lawn – just like any other robot mower, really – but once set up the unit, it (mostly) takes care of itself, being clever enough to return to its docking station in the event of heavy rain or when its battery gets too low.

One thing we like is that Landroid 800 M comes with Worx' Artificial Intelligence Algorithim (AIA) technology, which enables it to bypass narrow sections such as paths and then carry on mowing. It also includes a 'zone mode' which enables it to recognise discreet areas of your garden – front and back lawns, for example. It's also pretty good at tackling steeper areas, tackling gradients of up to 20-degrees (35 percent).

7. Husqvarna Automower 450X

Long-range robot mower with a price tag to match

Specifications
Mowing width: 24cm
Mowing height: 20-60mm
Maximum lawn area: 5,000m sq
Slopes: 45%
Battery type: 28v lithium
Charge time: 75 mins

Reasons to buy
+Ideal for large gardens+Can be monitored using a mobile+Long battery life+Fast recharging time
Reasons to avoid
-Eye-wateringly expensive

When it comes to robot lawnmowers, the Husqvarna Automower 450X is the Mercedes to Flymo's Ford: a gardening status symbol for people with deep pockets who want the very best.

You certainly get what you pay for. Aimed at larger lawns, with an operating range of up to 5,000 square metres, the Husqvarna Automower 450X also comes with a high-powered 28v lithium battery that can run for up to 4.5 hours on a single charge. That big capacity battery also charges relatively quickly too, meaning the mower's blades are ready to spin into action just 75 minutes after its returned to its charging base.

As you'd expect of a premium product like this, the Husqvarna Automower 450X can also be paired with the Automower Connect app (for iOS and Android), which enables you to keep tabs on your mower – and even tell it when to start, stop, park or adjust its cutting settings from anywhere in the world, all from your smartphone or tablet. It will even alert you and enable you to keep track of it in the event that it's stolen using its built-in GPS. How many mowers can you say that about?

Another luxury feature is its weather timer, meaning the Automower 450X will only cut the grass when it is growing most strongly, avoiding sunny and dry conditions to reduce wear and tear on the mower and your lawn.

8. Ambrogio L300 Elite R

Weight: 18.4-19.8kg
Reasons to buy
+Ideal for large gardens+Incredibly stylish design+Can be fitted with two batteries+Smartphone app control
Reasons to avoid
-Achingly expensive

If Ferrari made a robot lawnmower, it’d probably look at lot like this. 

There’s certainly no mistaking its influence on the Ambrogio L300 Elite R, whose siblings also lean heavily on Italy’s supercar heritage in their designs. And this mower certainly lives up to that billing. 

For a start, it’s capable of mowing huge areas of lawn (up to 6,000 square metres) when supercharged with not just one, but two 25.9v lithium ion batteries, giving it an incredibly long run time of up to 10 hours. It also comes with three sensors – a magnetometer, a gyroscope and an accelerometer – for precision cutting. And you can monitor and control the whole thing using the free Ambrogio Remote smartphone app for tablet or smartphone. 

Other goodies? The Ambrogio L300 Elite R also has clever self-cleaning wheels, can trundle up and down slopes other robot lawnmowers would be fear to tread. It’s even clever enough to alter the spin speed of its 36cm blades – faster for long grass, slower for short grass – and automatically does a spin cut in tougher areas for the perfect cut. 

Expensive, yes, but by crikey we want one.

9. McCulloch ROB R1000

Basic robot mower for now much money

Specifications
Mowing width: 17cm
Mowing height: 20-50mm
Maximum lawn area: 1,000m sq
Slopes: 25%
Battery type: lithium
Charge time: 50 mins
Average runtime: not stated
Coverage per charge: not stated
Noise level: 57-59db
Dimensions: 58.6x43.7x25.7cm
Weight: 7kg
Reasons to buy
+Ideal for small or medium sized lawns+Programmable controls+Anti-theft protection
Reasons to avoid
-Limited features-Stiff competition-Only operates within a single zone

Ideal for small to medium size lawns of up to 1,000 square metres, the McCulloch ROB 1000 is an ideal entry point into the robot lawnmower world. It’s not particularly flashy or feature-packed, but it performs all the usual robot lawnmower 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.

10. Gardena smart Sileno+

Intelligent robot mower with smartphone control

Specifications
Mowing width: 22cm
Mowing height: 20-60mm
Maximum lawn area: 1,300m sq
Slopes: 35%
Battery type: 18v lithium
Charge time: 50 mins
Average runtime: 65 mins
Coverage per charge: not stated
Noise level: 56-60db
Dimensions: 63x51x25cm
Weight: 8.5kg
Reasons to buy
+Ideal for larger, more complex lawns+Smartphone monitoring and control+Intelligent operation
Reasons to avoid
-Nothing really

The smart Sileno+ is part of Gardena’s smart system range, which includes things like automatic garden sprinklers. That’s handy because 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 the garden sprinter isn’t working – and vice-versa – and it also includes Gardena’s SensorCut System, which effectively measures the height of the grass and so 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. 

Affordable, good-looking and with brains to boot.
