With the summer months now giving way to autumn, now is a great time to shop for one of the best cordless lawn mowers of 2022.
This because the spring and summer rush to buy is over, new models have been released, and now end of line models are selling for a song.
And, that's specifically great for wireless lawn mowers, as they tend to cost more than wired models, so a big saving makes them much more affordable.
Wireless lawn mowers are also great as, being candid, they make mowing grass a lot easier and more convenient, as you don't have to worry about - or be restricted by - a pesky cable.
Without a cable, you don’t have to worry about it getting caught or tangled, or worse, mow through it! No more extension leads and faffing about with endless cables when you have a cordless lawn mower.
You’ll find the entire process of cutting your grass much easier with a cordless device, and you’ll be able to get it done much quicker so you can relax in the garden with a nice cold bevvy instead.
Each cordless lawn mower in this guide is batter powered, which makes them very convenient but if you’re looking for something else, we also have a guide on the best petrol lawn mower, or if you’ve got a huge garden or really don’t want to do much manual labour, then check out our guides to the best robot lawn mower and the best ride on lawn mower.
For smaller gardens that don’t need much work, we can also recommend the best small lawnmowers. They may be small but still get the job done well!

In our opinion, this little yellow garden pal from Kärcher meets all the criteria required of modern cordless mower.
The big 18v 5ah battery is a major asset because its edges are coated in a rubbery texture that should theoretically prevent the plastic housing from cracking if dropped. Uniquely, the battery also features a useful LCD screen that displays the remaining battery juice as a percentage and as a countdown in minutes when charging. When I tested it, I got about 40 minutes of use out of it (four cutting sessions), though it did take about two hours to fully charge. I should add that the battery needs to be pushed in firmly till you hear a click. You may even need to give it a good old shove to engage. Bear this mind, because some users have returned their units thinking they weren't working.
Although the handlebar system adopts the standard budget-priced wing-nut system for tightening, it’s a much more sturdy set up than others on the market and it’s also height adjustable to some degree, and foldable. The four-level cutting height lever, meanwhile, is of the cheaper variety, but it works perfectly well.
The Kärcher’s 33cm cutting deck, 35-litre grass catcher and decent cutting height range make the mower suitable for any small-to-medium sized lawn. What’s more it also comes with a mulching plug for those who want to feed nitrogen-rich cuttings back into the lawn.
If you’re looking for a lightweight and efficient lawn surfer that performs exceedingly well, then consider putting this one at the top of your list. I continue to use the Kärcher on a regular basis: it never bogs down even in longer grass and it cuts right to the edge. It also leaves a nicely manicured finish in its wake.

For a mower with a large 42cm cutting deck, the exceedingly good looking white Gtech CLM50 is one of the lightest (13kg) mowers in its category – so light you might think they’d forgotten to put a motor in it.
Unlike most lawn mowers, the Gtech CLM50 adopts a different type of blade. In fact, it’s half a blade with a counterweight on the other end. Made from carbon steel, this blade is said to be just as efficient while requiring less energy. All I know is that it cut my large test lawn supremely well, and right to the very edge of the border. It also produced finer cuttings than most other mowers I’ve tested.
The motor’s well worth a mention since it features automatic variable speed: in short to medium grass the blade rotates at a steady pace, but as soon as it feels the resistance of longer grass, it speeds up dramatically, cutting the offending fronds with effortless aplomb. I managed to eek just under 40 minutes of running time from the 48v battery, and it took just 60 minutes to charge.
Noise level is another major consideration when purchasing any lawn mower and this model is one of the quietest on test. The handlebar uses quick-release latches like most other manufacturers and it can be folded into three for easy storage. However, the handlebar height can’t be adjusted and, as it stands, it feels almost too tall for this 5’6” lawn smith. Other features include a fixed battery key that can’t be lost, a battery power indicator that is visible at all times and a large 50-litre grass collector that clips on and off with consummate ease.
Verdict? If you have a medium sized lawn and a price of £500 isn’t an obstacle, then slap some readies down on this one because it’s one of the best cordless mowers we’ve tested. It’s super light, a doddle to manoeuvre and it looks the business, too.
If you've got a small to medium-sized garden and want to maximise cordless bang for your buck, then the LawnMaster 24V Lawn Mower may be the system for you.
While its looks might not raise an eyebrow, the spec and runtime most definitely will, since this mower comes with not one but two 2.0Ah batteries. This gives you a total of 120 minutes of running time – enough to cover all but the largest of gardens. And the great thing is that, when one battery is in use, the other can be charged with the included charger, which can boost a battery back to full power in just 60 minutes.
In terms of cutting credentials, the LawnMaster certainly delivers the goods. It has a brushless motor and a 34cm blade that is perfectly sufficient for medium and smaller gardens (officially rated up to 300m2), while the included mulching plug is a handy addition for those who wish to inject some nitrogen back into the lawn. Also, its six different cutting heights – ranging from 20 to 70mm – means you have plenty of options to master the sward to your liking. Not bad at all.
This writer has been using this large 51cm cordless Cobra for 18 months and it’s a beast in every respect. The Cobra MX51S80V (opens in new tab) is equipped with an 80-volt brushless motor and it runs on two 40v 5Ah Li-ion batteries that just seem to last forever. In fact, after every first complete mow of my 200m² lawn, both batteries still show full power with all eight LEDs alight. Combined, the batteries should provide up to 92 minutes of cutting on a full charge.
Like its petrol-based stablemate, the Cobra MX534SP – which you can read about in our guide the the Best Petrol Mowers (opens in new tab) – a fan-type mechanism attached to the blade helps fling grass cuttings towards the back of the large 60-litre grass collector so it fills up much more than most other mowers I’ve tested – and that means fewer trips to the compost bin. As a byproduct, the blade’s vortex fan system also sucks up garden leaves like a vacuum cleaner.
The Cobra MX51S80V is an exceptional cutter and powerful enough to scythe through even long damp grass without so much as a hiccup. Moreover, the motor speed increases automatically whenever the blade detects extra resistance. And for such a large model, it’s one of the quietest cordless models I’ve ever used.
At 29 kilos, this mower isn’t light but the onboard single-speed self propulsion makes using it a breeze. That said, it doesn’t feel too unwieldy even when used without the self propulsion because it has nice big rubber wheels that help make it easy to push.
The Cobra MX51S80V has seven cutting heights (from 25-75mm) and comes with a mulching plug and a side chute. It also comes with both batteries and two fast chargers (about 60 minutes to charge from empty). The handlebar assembly, meanwhile, can be adjusted to a vast range of heights – from ultra tall to a profile that's low enough for even a gnome to comfortably use it. Granted, the propulsion lever is very springy so it’s a bit awkward to grip if you have weak hands but other than that minor niggle, I can’t think of a more efficient cordless model for large lawns up to and beyond 1,000m².
This is the smallest lawnmower known to humankind. It’s so tiny it comes in a box small enough to accommodate a pair of Wellington boots. And when you get it out of the box it looks like the best eighth-scale radio controlled car your kids will never get a chance to play with.
The really clever thing about this single-handed 25cm cordless mower is that it’s available in two different options. If you already own Gtech’s GT50 Grass Trimmer or HT50 Hedge Trimmer you can just buy the mower body (£89.99) and use it with the shaft and battery of the trimmer or hedge trimmer, or purchase the whole package, battery and all for £179.99.
So what’s this little toy-like product like as a mower? Well, if you have a really, really small lawn, you’ll absolutely love it because a) it cuts grass really well, b) it’s ridiculously light and c) it’s mostly a doddle to push around. In fact the action of using it is just like vacuuming a carpet.
No, it doesn’t come with a grass collector (the cuttings are fed back to the lawn) and you will need to spring both axles into a lower position for a shorter cut – which is nowhere near as short as most large mowers are capable of (40mm instead of around 30mm). Also, some elderly users may find the action of mowing with just one hand a little tiring.
But on the plus side, its light enough (just 3.5kgs) to easily carry up some garden steps, its handle is suitable for all heights of user and it’s really easy to store. The battery, meanwhile, is capable of running for up to 30 minutes at a time.
If you have a stamp-sized garden and are looking for a mower that cuts a neat path with little fuss, give this little Gtech SLM50 a whirl.
If you have a small urban lawn with an area of up to about 180 square metres and require a plucky little model that’s easy to use and very efficient, give this model a try. The Gardena PowerMax uses two 18v batteries that share compatibility with most Bosch cordless products. These batteries must be used in tandem. Unfortunately, Gardena only supplies one charger with the package so you will need to charge both batteries in succession, which is a bit of an inconvenience. You should get about 35 minutes of cutting time out of a full charge.
We’re always looking for innovation when reviewing lawn mowers since most models cut grass very well. In this instance it’s the cutting height adjuster. Instead of pulling a lever to raise or lower the deck, the PowerMax features a QuickFit knob that is really easy to use. Simply push down on the knob, turn the dial to your preferred cutting height and the whole chassis springs up or down through ten cutting height levels, from a lower-than average 20mm to 60mm.
The motor itself is of the brushless variety so you can expect decades-long reliability from it. Add a decent 30-litre grass collector, a mulching plug and a very comfortable handlebar, and you have one very decent little operator that performs remarkably well on any urban-sized lawn.
If the excellent little Kärcher reviewed above is too small a model for your sward, consider getting your mitts around this equally excellent larger model which has a cutting deck of 36cm. Granted, an extra 3cm of blade width doesn’t sound like much but in the course of an average cut it will definitely shave off a few minutes. The larger 45-litre fabric grass collector (10 litres more) will also entail fewer trips to the compost heap. And like the smaller model, this one also comes with a mulching plug.
Aside from the larger body and bigger grass box, the 18-36 also benefits from a more widely adjustable folding handlebar so it’s arguably an even better choice for users of shorter stature. But perhaps the biggest improvement over the smaller model is the height adjustment method. Where the 18-33 involves a short bendy plastic lever that is admittedly a bit fiddly, this one has a whopping four-level gear stick that is a cinch to engage. Its cutting height range, too, is a bit wider than its diminutive stablemate.
The 18-36 uses exactly the same rubberised 18v 5aH battery and, as this writer has eulogised above, it’s the best cordless battery system I’ve thus far used. Its LCD not only displays accurate battery level in percentages, it just seems to go on and on. Like the smaller model, I’m guessing you’ll easily get 40 minutes of cutting time out of it. The 18-36 weighs more than the 18-33 and it’s not quite as effortlessly manoeuvrable, but it’s a no brainer if you have a medium-sized lawn.
To see how this top-rated mower stacks up against quality competition, then be sure to check out T3's Kärcher LMO 18-36 vs Gtech Cordless Lawnmower 2.0 (opens in new tab) comparison feature.
Designed in the UK, this T3 Award-winning cordless Cobra is equipped with a small 34cm cutting deck and a 35-litre fabric grass collector, making it the perfect little mower for an average sized urban sward. Being so small and made almost entirely of plastic, it’s light enough to carry and a doddle to store. It’s also admirably quiet.
Despite using a brushed motor instead of a more expensive brushless one, this titchy mower really impressed us with its cutting efficiency, even in relatively long damp grass. We estimate about 30 minutes of use on a single one-hour charge of its Samsung battery – enough power to cover up to three separate sessions on a small 10m x 8m lawn. For added convenience, it has a battery power indicator just below the start button on the handlebar.
The Cobra sports five cutting heights (25mm to 75mm), a simple height adjustment lever and, for the price, a very good collapsible handlebar system that incorporates quick-release clips instead of awkward screw threads. This is a great value model that’s efficient, easy to manoeuvre and compact enough for easy storage.
We've got a great Cobra MX3440 vs Einhell GE-CM 18/33 Li (opens in new tab) comparison feature that supplies even more detail about this top cordless lawn mower.
The Bosch CityMower weighs just 9.9kg so it’s really easy to push around and carry between lawny sections. Crucially, it comes fitted with Bosch’s comfy Ergoflex handlebar system that is perfect for both righties and lefties.
For those with a typical urban lawn, this thing passes much muster. Its height adjustable 34cm cutting deck and 31-litre grass collector are of optimum size for a 300 square metre lawn and, because it's fitted with extended grass combs, it also cuts right to edge of the lawn. And that means less strimming.
The CityMower has also got a clever processor on board that ensures the blades maintain a constant speed through any length of grass, thereby allegedly increasing the 18v battery’s capacity by up to 20%. Even with that boost, the mower will run for about 25 minutes on a hour-one charge, which is about average for a mower of this dimension.
The CityMower comes with a battery but if you already own a set of Bosch power tools that use the 18v system then opt for the ‘solo’ model and use one of your own batteries instead. This little compact mower cuts exceptionally well and is light enough for even the weakest knee’d lawn smith to push around and carry, and being a Bosch, you can be sure it’ll go on running for many summers.
German brand Einhell enters the swardsmanship market with a great budget-priced model that, while not the prettiest of lookers, does the job and does it well. This is a 33cm mower so consider it if you have a small lawn; at just 10.9 kgs, it’s also light to carry and easy to store.
The Einhell GE-CM 18/33 LI model comes with a battery and charger and is one of the cheapest ready-to-run models you can buy. It’s generally well designed and equipped with a brushless motor for unswerving reliability, a simple fold-over handle bar assembly for easy storage, and a three-setting height adjuster that takes the chassis from 25 to 65 mm – enough range for most types of common grasses.
If you’re not bothered by looks and just want a descent small-bodied mower that costs less than £200 complete with battery and charger, then you can’t really go wrong with this Einhell.
Here’s another top trimmer for small to medium sized city lawns. In our test the Greenworks performed very well, collecting every last tuft of turf while leaving a very smooth finish. It comes with a 35cm (14 inches) cutting deck, a 40-litre collapsible mesh grass collector, five cutting heights (20mm to 70mm) and an interchangeable 40v Li-ion battery that keeps the freakishly quiet brushed motor running at full tilt right up to the last drop of juice.
The Greenworks is a doddle to push around and, at 15kgs, it’s easy enough to carry. I managed to get three separate cuts out of the battery, equating to around 30 minutes of continuous use on a single charge. Available with or without a battery, the Greenworks is a great budget priced option for hassle-free cordless mowing of smaller lawns.
Like small city cars vs large cars, bigger mowers tend to feel and look more luxurious. They are also likely to be equipped with fancy telescopic handlebar systems and slick cutting height adjusters. As a consequence, large-bodied mowers are also proportionately more expensive to buy than their smaller brethren. But what if you had a large suburban lawn and didn’t want to spend a fortune on a cordless mower big enough to handle it?
Enter this wide-bodied stablemate to the T3 award-winning MX3440V reviewed above. The Cobra MX4340V has a wide 43cm (17-inch) cutting deck, 50-litre fabric grass collector and a brushless motor that are all on a par with premium-priced models like the Gtech and Greenworks. However, this model costs almost half the price, complete with 40v 5Ah battery and charger. Uniquely, it even has a battery power indicator on the handlebar assembly to let you know how much juice is left. And speaking of juice, you should get up to 50 minutes of running time out of it which is exemplary for a mower of these dimensions.
Yes, the folding handlebar system isn't as posh as some of the more expensive models but, guys, it’s a mower not a status symbol.
This cordless Flymo has the narrowest cutting deck on this page (30cm) so definitely consider it if you have a titchy lawn. You shouldn’t have any problems storing it either since it’s not only the smallest folding mower we’ve come across but it stores in an upright position with its 30-litre grass collector clipped to the handle bar. Of course, being so small means it is blooming light, too – like 8.8kgs light.
The EasiStore is equipped with two 20 volt batteries which gives it a max rating of 40 volts. No I’m not sure either why Flymo didn’t just use one 40v battery instead.
Nevertheless, you can charge both batteries at the same time (three hours) using the simple splitter device that comes with the charger. You should get about 30 minutes of mowing time out of the batteries, which is about average for a baby mower.
The EasiStore cuts just fine and pretty close to the edge – it even has a rear roller for creating stripes on the lawn. It’s also quiet enough to not scare the neighbour’s children. However, I’m not impressed with the cutting height system which requires manhandling the front and rear axles and clipping them into a lower or higher position. Other than that rather irritating foible, the Flymo EasiStore 300R Li is still a worthwhile model for postage stamp-size lawns.
Why cordless lawn mowers are typically the best lawn mowers
For most lawns men (lawns persons?), we'd always recommend a cordless mower such as the ones listed above.
That's because there are few less compatible duos than a 240-volt electric cable and a fast-spinning blade, and with UK garden sizes ever shrinking, petrol mowers are just totally OTT for most people, especially in cities. We estimate that the whole cordless mowing process from getting it out of the shed to finishing the job is almost twice as fast as when using a corded model.
However, some cordless models may struggle in extra long grass so best avoid tackling any untamed pastures (we’re talking really long grass here, the sort that hasn’t seen a lawnmower in months). If cutting grass that's about six inches long, fear not if your cordless model cuts it unevenly, leaving chunks of flattened grass in its wake. This is normal for any mower doing its first cut of the season. The secret is to set the cutting deck to the highest setting and tilt the mower back in long grass so the blade doesn’t bog down. Once you’ve completed one pass, run over the lawn again in the opposite direction or, better still, leave it after the first cut and return a day later for its second cut. Then gradually lower the cutting deck for subsequent sessions until it looks like a golf course fairway. At least that’s the theory.
Cordless mowers' lithium-Ion batteries are relatively quick to charge and provide between 25 and 60 minutes of hassle-free mowing, which is plenty long enough to completely cut an average UK garden.
How we test lawn mowers
A good example of how T3 performs hands-on testing of cordless lawn mowers can be seen in our Stihl RMA 443 VC review (opens in new tab). We have a clear methodology when reviewing products and mowers are no exception, with us first assembling and then using wireless lawn mowers to actually cut grass ourselves in a real world environment.
Take the Stihl RMA 443 VC coverage as an example. In the picture above, Deputy Editor of T3 (and budding gardener) Robert Jones is shown in videos and pictures actually using the mower. He also provides his personal, hands-on experience with the mower, talking through his findings in terms of design and build quality as well as performance and features.
We don't just rely on what a manufacturer says about their product – we test cordless lawn mowers ourselves, looking out for key signs of quality. If a mower misses the mark, we'll let you know, while if it slays sward like a pro then you'll know. The best mowers on the market end up in T3's best cordless lawn mowers buying guide.
Other gardening buying guides
T3's got some great garden buying guides covering the best products in a number of areas, of which lawn mowers is just of them. We've also got a great range of BBQ buying guides, for example, including the best BBQs (opens in new tab) and best portable BBQs (opens in new tab), as well as an authoritative guide to the best pressure washers (opens in new tab) and best outdoor lighting (opens in new tab) on the market, too.
