The best lawn mowers 2021
1. Worx 40V Cordless Lawn Mower
The best value lawn mower
Specifications
Reasons to buy
Reasons to avoid
If you want to step away from a petrol mower, but not be inhibited by the battery running time, the Worx 40V Cordless Lawn Mower could be the one for you. It is a highly affordable step into cordless mowing, that won't leave you missing out on function.
Two modes
The Worx 40V cordless can be used in Turbo or Eco Modes. Eco helps the battery last longer, yet Turbo mode adds a little more oomph and is noticeable over thicker grass. Working alongside these modes is Intellicut technology which adjusts the speed automatically with different grass conditions, so it keeps consistent cutting efficiency in dense grass.
Cutting power
The deck design of this mower will cut grass close to fencing/walls, leaving a smaller uncut grass area around the edges. It also has six cutting height settings which range from 20-70mm.
Power
It's powered by two, rechargeable 20V batteries simultaneously which provides extra power and runtime. Worx estimates you should get 30–35 minutes from one charge with them, which should be plenty enough for lawns of around 280m2. You can even share the battery with other tools in the Worx range.
Gardeningetc rating 5 out of 5 stars – read our Worx 40V Cordless Lawn Mower review for more details.

2. Gtech Cordless Lawn mower 2.0
The best cordless lawn mower for big gardens
Specifications
Reasons to buy
Reasons to avoid
A close contender to our top spot, this Gtech lawnmower narrowly missed out on first place just because of that price tag of around £500. If you have the budget, then it is worth considering.
Time saver
With a 1 hour charge time, you’ll be ready to mow without too much hanging around with this model. Once you start, there’s up to 40 minutes of running time and, because the mower has a 50ltr grass box, you can cut down on emptying trips. It has a cutting width of 42cm, which means fewer passes before you’re done.
Cutting height
There’s a choice of cutting heights between 30 and 80mm in 10mm increments with this mower, giving you plenty of options.
Fold-down
Limited room in the shed or garage to stow your mower? You’ll like the fact that you can fold this model down to tidy away.
3. Flymo EasiLife 200 Robotic Lawn Mower
The best robot lawn mower overall
Specifications
Reasons to buy
Reasons to avoid
You can relax – or more likely get on with some other essential task – and let the Flymo Cordless EasiLife 200 Robotic Lawn Mower mow for you.
Robo-gardener
This robot mower is suitable for lawns up to 200m2 – in other words, up to medium size. It can work on gradients up to 35 percent. Before it can get to work, you’ll just have to position the charging station and set up the boundary wire that defines the cutting area.
Working practices
The mower adapts the cutting schedule automatically based on the lawn growth and weather conditions, and mows in an irregular pattern for full coverage and to avoid track marks. It mulches so you don’t have to worry about emptying a grass box. It takes itself back to the charging station as necessary, too.
Smart features
You can set the schedule from the keypad or via the EasiLife app. With the latter, you can access mower status and support information from your phone.
Gardeningetc rating 4.5 out of 5 stars – head over to our Flymo Cordless EasiLife 200 Robotic Lawn Mower review for the full details.

The best petrol lawn mower you can buy
Specifications

Smart finish
Whether you have long or short, damp or dry grass this lawn mower will make light work of slicing through even the toughest clumps for a neat appearance.
More grass
You can stop less with a generous 60ltr capacity grass box. It also comes with a mulching plug that finely cuts grass trimmings into a nitrogen-rich mulch which is then recycled back into the lawn as a natural fertilizer.
Made to last
A steel chassis makes this a robust mower that’s made to keep on cutting. All round it is an amazingly well-built machine that will last a long time
5. Bosch CityMower 18 cordless
The best cordless lawn mower for urban gardens
Specifications
Reasons to buy
Reasons to avoid
Want an affordable cordless mower for a relatively small plot? This Bosch CityMower 18–300 is just what you need.
Perfect for smaller urban gardens
When you need a mower that will do small jobs quickly and easily, this is a great choice. It has an average battery life of 25 minutes, even when in boost and should be plenty for a small plot. Light and compact, getting it out and putting it away is fuss-free too.
Light yet powerful
This mower made light work of the first cut of spring – getting through an overgrown lawn with no trouble. The power it packs is surprising consider the compact package, though our reviewer did note that in a big to be lightweight, some of the parts do feel a bit flimsy.
Extra battery for more power
This mower is part of Bosch's Power for All Alliance range so you can buy extra batteries if needed. Great for adding some length to your mow time and you can have one on charge while you work.
Gardeningetc rating 4 out of 5 stars – read our Bosch CityMower review for more details.
6. Greenworks G40LM41 Cordless Lawn Mower
Best large capacity cordless mower for your budget
Specifications
Reasons to buy
Reasons to avoid
For a cordless lawn mower that’s up to the task of cutting a big lawn, look no further than the Greenworks G40LM41 Cordless Lawn Mower.
High capacity
This mower can keep lawns of up to 600 square meters neat. It has a 50ltr grass box, a cutting width of 41cm, and the options for cutting heights run from 25 to 80mm.
Multi-use battery
This version doesn’t come with a battery because if you already have a Greenworks garden or workshop product with a 40V battery you can use that, and won’t end up buying the same thing twice. However, you’ll find the same mower on sale with a battery if you’re not already equipped.
Lawn care
There’s a mulching facility on this model, which means you can keep the lawn healthier, and you don’t have to dispose of clippings. But you can collect the grass if you prefer.
7. Einhell GE-CM 18/30 Li Cordless Lawn mower
The best lawnmower for irregularly shaped gardens
Specifications
Reasons to buy
Reasons to avoid
Packed a whole lot into your small or medium-sized garden? The Einhell GE-CM 18/30 Li Cordless Lawn Mower can work efficiently around the features.
Tricky corners
Easy to move and pretty light at 9.71kg, this mower also has large wheels that protect the grass and it will get up to edges a treat.
Chop and change
The battery is part of a system where one battery fits all the power tools, so you don’t end up with multiples. It takes two hours to charge.
Lawn options
There are just three cutting heights from 30 to 70mm available, which is less choice than other models offer but may be all you need for lawn care.
8. Worx Landroid M500 robot lawn mower
The best quiet robot lawn mower
Specifications
Reasons to buy
Reasons to avoid
Another robot lawnmower option is this model from Worx. It is smaller than it looks but do not be fooled because it will keep your lawn well maintained, especially if you have an uncomplex garden.
Mowing tech
Designed to mow your lawn often, the Landroid has patented mowing AIA cutting technology which ensures that it can navigate and mow narrow spaces really easily. This one also comes with optional extras such as voice control, ACS obstacle control, anti-theft, and digital fence which make the robot mower even more intelligent.
It also has a mulching function to maintain your garden which reuses the clippings to serve as a natural fertilizer.
Smart features
Controlled by an easy-to-use app, this robot lawnmower will mow your entire lawn with just the touch of a button and even set up a mowing schedule. The app is called Landroid which can be downloaded to your iPhone or Android device, and be used across your home Wi-Fi connection.

9. LANDXCAPE LX799 300m2 Robotic Mower
The best affordable robot lawn mower
Specifications
Reasons to buy
Reasons to avoid
If you would like a robot lawnmower but your budget is smaller than that of our two recommendations above, then consider the LANDXCAPE LX799.
Mowing tech
With a 16cm cutting width and a cutting height of 20 to 50mm, this LANDXCAPE mower can tackle gardens with a 15˚ incline. The patented mowing technology built inside this lawnmower enhances its efficiency by 30 percent, while it uses both forward and reverses rotations in order to reduce the wear of the blade by half. There's a three-blade cutting/mulching system meaning that similar to other robot lawnmowers, it cuts the grass and disperses it back into your lawn to be used as a fertilizer.
Ease of use
This robot lawnmower is better for smaller gardens – up to 300m2 – and it will take itself home when power is low. It also doesn't need to be programmed and will start mowing at the press of one button. It has bump sensors so as not to hit your furniture (or the kids' climbing frame), while the robot will navigate away from narrow or tricky paths, too. Though not Wi-Fi enabled, it's very easy to use as it features a keypad on the top of the device.
Safety
The LANDXCAPE mower requires a PIN code to work – this will protect the lawnmower from unauthorized activation. If the mower is picked up, its blades will stop moving immediately.
10. Hyundai 196cc Self Propelled Push Button Start Petrol Lawn Mower
The best petrol lawn mower for big jobs
Specifications
Reasons to buy
Reasons to avoid
Got some serious mowing to tackle? The Hyundai 196 cc Self Propelled Electric Push Button Start Petrol Lawn Mower is a mower enough for the job.
Easy start
If you don’t like the idea of a pull-start, this mower’s got your name on it. It has a push-button electric version although there is a recoil pull-start back up.
In control
The mower is self-propelled and you can choose from four speeds to get the pace you’re happy moving at.
Keep going
With a 70ltr grass box, you can keep mowing without to-ing and fro-ing to empty. The petrol engine is designed for low fuel consumption, so you can keep going for longer on a single tank. It is perfect for big gardens with lots of lawn.
11. Einhell GC-PM 40 S Self Propelled Petrol Lawn Mower
The best petrol lawn mower for large gardens
Specifications
Reasons to buy
Reasons to avoid
A petrol mower at a value price point, the Einhell GC-PM 40 S Self Propelled Petrol Lawnmower is a no-pushing-needed option.
Lighten up
Petrol mowers can be weighty, but at 21.7kg, this model won’t prove awkward – plus you don’t need to push either because it’s self-propelling.
Size matters
You can keep a big lawn neat with this model. It’s recommended for areas up to 1,000 sq m.
Grass catcher
The grass basket has a fill level indicator so you know when to stop and empty, plus it has two handles so the job’s easier.
12. Bosch 600886103 AHM 38 G Manual Garden Lawn Mower
The best manual lawn mower
Specifications
Reasons to buy
Reasons to avoid
A great pick for small gardens, with a brilliant price point to match, the Bosch 600886103 AHM 38 G manual garden lawnmower makes simple garden maintenance even more enjoyable.
Lightweight but heavy-duty
Weighing in at just 7kg makes this manual lawn mower a doddle to work within small spaces, while the high geared side wheels give you even more freedom of movement for a more efficient run. If you lack power points, can't afford cordless and don't want the fumes of petrol, a manual mower like this is for you.
In-built design
The combination of a mounted cylinder of blades and a fixed blade underneath helps deliver a precise cut every time. The height of the cut achievable is between 15-43mm.
Decorative garden features
If you're into lawn care and design, then you'll enjoy the ability to create the classic lawn stripes in your space using the rear roller – which will also offer you superb stability, right up to lawn edges.
13. Flymo Hover Vac 250 25cm Collect Lawn Mower
The best electric lawn mower for small gardens
Specifications
Reasons to buy
Reasons to avoid
There’s no point in spending out on a big mower if your lawn’s on the diminutive side – the Flymo Hover Vac 250 25cm Collect Lawnmower will do all you need.
Light work
The mower itself isn’t heavy at just 6.9kg, and the other big plus point is that it floats on air so it’s easy to use.
Plug-in
This design has a cable that’s 10m long so you’ll have plenty of room to maneuver in a small garden. You don’t need to remember to charge a battery, either. The downside? You need to avoid the cable.
Lawn looks
There are only three cutting heights from 10 to 30mm, and you can’t get a stripe, but for a small garden, this compact-to-store design will do the biz.
14. Ryobi RY18LMX40A-0 18V ONE+ Cordless Lawnmower
The best brushless electric lawn mower
Specifications
Reasons to buy
Reasons to avoid
Precise and easy to run, the Ryobi 18V ONE+ is a nifty machine that's ideal for quick and powerful garden lawn maintenance.
Brushless can be better
A brushless motor means that the battery power is usually increased, which explains why the Ryobi 18V ONE+ performs well in all lawn mowing departments: cutting, mulching, and bagging. It works well on one battery, but there is the option of using two for an even bigger boost.
Precise cutting path
The 40cm cutting path makes this model ideal for medium to large lawns, while the EasyEdge feature lets you mow right up to walls, fences, and other features in your garden for a smooth and easy job.
Comfort is key
The Ryobi 18V ONE+ has a telescoping handle that is fully adjustable, letting you set it to the height required for optimum accessibility and maneuverability.
How to buy the best lawn mower?
Petrol or electric: which is best?
You can pick between mowers powered by electricity, those that use petrol, and even lawnmowers you simply push yourself. Within the electric mower range, you’ll find both those that have cable and cordless versions with a battery you’ll need to charge.
Mowers with cables A mower with a cable has a limited range, of course, so check there’s sufficient length to get around the entire lawn. These don’t take up a lot of storage space.
Cordless mowers
These designs aren’t limited by a cable. Pay attention to charge time and maximum battery life if you want one of these to ensure you’re happy with the numbers. Robot lawnmowers are a type of cordless mower – just one you don’t have to push.
Petrol mowers
These will cope with big gardens, but there’s nothing to stop you from having one for around 100 square meters and upwards. They are powerful and should help you get finished faster. Bear in mind that you’ll need to buy and store the petrol and oil and get one of these serviced.
What about manual mowers?
You might wonder why you wouldn't want a powered option, but manual mowers offer plenty of versatility. They are a great choice if you have a long garden with no power points taking electric corded versions off the table. They don't need fuel like a petrol mower (and won't smell/pollute) and are far cheaper than cordless options. If you consider yourself fairly fit or just have a small lawn to deal with, a manual is a good choice.
How much should you pay for a good lawn mower?
You can pick up a mower with a cable from a very low price point, while a cordless version with a battery onboard is more costly. Generally speaking, the more high-tech and feature-filled they get, the more expensive they will be. What you spend, depends on the investment you want to make.
Prices start as low as around the £50 marker for a manual mower, creeping swiftly up between £100 and £250 for mid-range mowers, while next-level cordless varieties and robot mowers especially can range from anything between £300 and £700+.
What types of lawn mower are there?
You’ll find cylinder, rotary, and hover mowers on offer. Cylinder mowers have a rotating set of blades that cut against a fixed blade. They’ll keep a small lawn looking neat and tidy.
The vast majority of lawnmowers are rotary with a single horizontal blade on the bottom that rotates at speed. They’ll cope with grass of different lengths and uneven as well as flat lawns.
Hover mowers are different again and hover on a cushion of air. They’re best used in small to medium gardens but will cope successfully with uneven grass and slopes.
What about the grass box?
How many trips you make to empty the grass box will be determined by its capacity. If you don’t have much to mow that’s not an issue, but the bigger the garden, the more the grass box should hold.
You may want to go for a mower that mulches, cutting the clippings into finer pieces and then returning them to the lawn where they add nutrients.
Go for a mower without a grass box and no mulching feature and you’ll be raking up the grass at the end.
What about cutting width and height?
The wider the cutting width the mower offers the bigger the area it cuts in one go and hence the faster you’ll finish a mowing session. For a large lawn, go for 40cm and above; 30cm is fine for a small lawn, and between the two will work for a medium lawn.
Adjustable cutting heights are handy: they’ll allow you to set the height you want the grass to be when you’ve finished.
What other features should you look out for in the best lawn mower?
Don’t want to push the mower? Look out for a self-propelling mower. If you want stripes on your lawn, you need a mower with a rear roller. A foldable handle, meanwhile, will mean your mower demands less storage space.
