Best cordless lawn mower 2025: top battery-powered trimmers that tackle all types of turf

If you haven’t tried the best cordless lawn mower yet, now’s the time. Aside from the safety aspect of not having a 240-volt cable within splitting distance of a fast-spinning blade, the best thing about cordless mowers is the time saving you make by not having to unfurl the cable in the first place.

Today’s battery-powered cordless mowers are invariably as powerful as their electric cable-driven associates while their high-tech Lithium Ion batteries are quick to charge and provide between 25 and 60 minutes of hassle-free mowing – plenty long enough for the average UK garden. That's why the Worx Nitro 80v WG761E is our top pick.

This best cordless lawn mower guide takes you through the top options on the market, and offers some buying advice, too. If cordless is not what you want, we also have a guide to the best robot lawn mowers.

Best cordless lawnmowers 2025

The best cordless lawn mower

This relatively new model from Worx is a direct contender for a bunch of models found below, but it just pips them all to the winning post by dint of several unique and very innovative features.

The mower itself is a joy to use, with a rock-solid aluminium handlebar that adjusts to three heights, smooth self-propulsion, and a 51cm steel deck with easy seven-step height adjustment (20-80mm). It even boasts bright LED headlights for late mowing sessions.

Performance-wise, it’s a beast. With Intellicut tech that automatically boosts torque for tough grass, it cuts beautifully and runs for up to 55 minutes – which is more than enough for a 1000m² lawn. The 70-litre grass collector reduces emptying trips, and the built-in mulching system ditches the need for a fiddly plug. All you have to do is just slide a lever and mulch away.

If you have a medium to large sward that you want to keep in immaculate condition, this keenly-priced cordless beast will do the task and do it superbly well no matter the length of grass. It’s amazingly well equipped, not too loud, extremely efficient and powerful enough to confine your current petrol mower to the history books.

The best cheap cordless lawn mower

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 – and of course, wonderfully affordable.

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 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 comparison feature that supplies even more detail about this top cordless lawn mower.

The best premium cordless lawn mower for large lawns

Weighing in at just 31kg, the sleek Ego+ LM2021E-SP is lighter than many rivals, making it easy to push when needed. Its 50cm steel deck and powerful 56V 5Ah ARC Lithium battery deliver up to 40 minutes of cutting time, with a Rapid Charger that refuels the battery in just 40 minutes.

The self-propulsion is a standout, offering smooth speed control via a rocker switch, gentle takeoff, and the option to engage propulsion without spinning the blade. The robust, height-adjustable handlebar folds down neatly for upright storage, and LED headlights add a fun, practical touch for after-dark mowing.

Performance is exceptional – it powers through tough grass with ease, rivaling petrol mowers for cutting torque. The specially designed blade throws clippings deep into the 60-litre collector, and you also get a mulching plug and side chute for flexible cutting options.

It’s pricey, but if you want premium build quality, serious power and versatile cutting performance, the Ego LM2021E-SP is worth every penny.

The best lightweight cordless lawn mower

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 factor when purchasing any lawn mower and this model is one of the quietest on the market and the low growling sound it makes is quite different to other models. 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 price 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 a good looker to boot.

The best cordless lawn mower for medium lawns

The Worx WG743E weighs around 14.5kg so it’s very easy to push around and carry between lawn sections using the chunky orange handle. Crucially, it comes armed with two 20v 4Ah MaxLithium Pro batteries which combine to provide 40 volts of oomph. It also comes with an excellent single-unit dual charger so you can top up both batteries at once. The batteries provide up to 30 minutes on a full charge, which is about par for the course with a low-priced mower like this. As an added bonus, this mower’s batteries are the same as others in the Worx range so you can hot swap them from the company's other garden tools like the amazing Worx Leafjet WG543E blower we review in our guide to the Best Leaf Blowers.

For those with a small to medium urban-cum-suburban lawn, this model passes much muster. Its five-position cutting height adjustment (3-9cm), wide 40cm cutting deck and ample 45-litre mesh grass collector are of optimum size for a 500 square metre lawn. Moreover, this model also ships with a mulching plug that blocks the exit chute. This is so that the nitrogen-rich cuttings can be forced back into the turf which in turn helps keeps the lawn naturally fertilised.

Although the Worx’s handlebar system is very basic, it can at least be folded for easy storage. Also, this writer has detected a modicum of rear suspension in the chassis that may or may not soak up rougher terrain. Whatever, it’s an interesting addition and something I’d like to see on all lawn mowers.

The Worx WG743E cuts exceptionally well – and right to the edge – so if you’re in the market for a keenly-priced and very efficient mid-sized cordless lawn mower, step right this way.

The best cordless lawn mower for small lawns

Although Kärcher is more famously known for its pressure washers, the German company has done its homework and produced a pair brilliant mowers that compete very favourably with the more established brands. For this guide we’re focusing on the larger LMO 18-36 model with a 36cm cutting deck, but if you need a smaller model, head over to our guide to the best small lawn mowers and check out the Kärcher LMO 18-33 instead.

If you have a small-to-medium lawn, you could do worse than get your mitts around this excellent cordless model which has a cutting deck of 36cm, a 45-litre fabric grass collector for fewer trips to the compost heap, and a nice big height lever that takes the cutting deck from 30-70mm. It even comes with a mulching plug for those who like to mulch much mulch.

The Kärcher 18-36 comes with an 18v 5aH battery that’s one of the best in this price range. Its LCD not only displays accurate battery level in percentages, but it just seems to go on and on. I’m guessing you’ll easily get 40 minutes of cutting time out of it. At a smidge under 14 kilos, this one’s a no brainer, especially if you have a medium-sized lawn.

To see how this top-rated mower stacks up against the competition, be sure to check out T3's Kärcher LMO 18-36 vs Gtech Cordless Lawnmower 2.0.

The best cordless lawn mower for urban lawns

If you have a small to medium-size urban lawn and require a plucky model that’s very easy to use, extremely efficient and a doddle to store, give this model a whirl. The Flymo 36V UltraStore 380R uses two 18-volt batteries in tandem which combine to produce 36 volts of overall power. Unfortunately, Flymo 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 Flymo’s amazing ability to be wheeled around like a shopping trolley and then fold up into a tidy package that can be stored vertically with the grass box attached. If you have a tiny shed, this may be the mower for you.

This mower comes with a 38cm cutting width, a large 45-litre plastic grass collector and a decent cutting height selector than can raise and lower the cutting deck from 60mm down to a lower-than-average 20mm. At 11.9kgs, it’s also one of the lightest mowers on test.

Add the included mulching plug and decent folding handlebar, and you have a very competent operator that performs remarkably well while being one of the easiest mowers to store away.

The best ergonomic cordless lawn mower

Stihl waltzes onto the turf with a stupendous machine that looks like no other mower on the market. Instead of a standard two-strut handlebar that’s awkward to fold and a bit rickety, the RMA 339 comes with an unflinchingly solid mono bar that simply unlatches and folds over on itself. The bar can also be easily adjusted to two heights with a simple flick of a latch.

However, it’s not so much the folding aspect that makes this handlebar arrangement so unique, it’s the massive amount of free space it provides on the left hand side when it’s time to lift out the grass catcher. With other mowers, the act of removing the grass box involves two moves: one to unlatch the grass collector from between the handlebar and the other to reach around the back of the handlebar to pick it up. By contrast, with this model you simply lean down, unlatch the collector and pick it up. All in one tidy move. Another handy facet is that the top of all-plastic 40-litre grass collector can be unhinged to empty it all at once without having to shake it up and down.

From a mowing point of view – which is, after all, what you’re most interested in – the Stihl is a lawn virtuoso, cutting grass evenly and with little fuss, almost to the very edge. It’s pretty heavy but easy enough to manoeuvre and its wide 37cm cutting deck is a great size for medium sized lawns. The height adjuster is one of the best yet – just pull the handle out a few centimetres and lift or lower the cutting deck with little effort.

Like the Gtech above, this model also features automatic blade speed adjustment. This means that in standard-length grass the motor hums along at low revs, saving battery power in the process. But when it detects a section of long grass, it seems to almost double the power, scything through it like a knife through blancmange. As soon as it’s passed through, the motor reverts to its more sedate pace again. You can safely expect about 40 minutes of cutting time on a full charge.

As is the case with most Stihl products, this mower is available with or without a battery or charger – if you already own any Stihl products that already use the 36v system, you can simply hot swap between tools. For the well-heeled lawn smith looking for a reliable, efficient and superbly designed mower that’s a pleasure to use, this Teutonic model is about as impressive as it gets.

The best cordless lawn mower for battery

If you've got a smallish 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.

The best self-propelling cordless lawn mower

This large 51cm cordless Cobra is a beast in every respect. The Cobra MX51S80V 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 90 minutes of cutting on a full charge.

Like its petrol-based stablemate, the Cobra MX534SP (which you can read about in our guide to the Best Petrol Lawn Mowers), 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, this large-bodied mower is almost up there with the equally impressive EGO+ LM2021E-SP, reviewed above.

The best budget cordless lawn mower

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.

How to choose the best cordless lawn mower

Choosing a new cordless lawn mower can feel overwhelming, but we’ve narrowed down the key things to consider before you invest. Let’s face it, these machines aren’t cheap, so it pays to know what to look for.

Start by thinking about your lawn size and how much runtime you’ll need. For smaller lawns (under 200m²), a compact mower with a smaller battery and cutting deck (30-38cm) will do the trick. Larger lawns (500m²+) call for wider decks (45-52cm) and higher-capacity batteries (at least 5Ah). Opt for lithium-ion batteries as they hold their charge better and last longer.

If your garden is large, uneven or sloped, self-propelled mowers are worth the extra spend, saving your legs from hard work. For flat, smaller lawns, a push mower is lighter, cheaper, and perfectly fine. You should also look for a mower with easy-to-use height adjustment, ideally offering 5-7 cutting heights so you can tackle everything.

Lastly, extra features like LED headlights, folding handles and ergonomic controls can make mowing much easier, and help you get the most out of your purchase. The little details are definitley worth opting for as well as the big specs.

Best cordless lawn mower FAQs

Should I buy a cordless or robot lawn mower?

If you’re after a more affordable option that gives you full control over your mowing path, a cordless mower is a smart choice. It’s better suited to uneven ground, comes at a lower price point, and still delivers impressive performance thanks to modern battery tech.

At the end of the day, it’s all about what works best for you – and whichever option you choose will be the right one for your garden.

Are cordless lawn mowers waterproof?

In general, cordless lawn mowers are not fully waterproof, but most are designed to be weather-resistant to handle light rain, damp grass and the occasional splash. That said, manufacturers usually advise against using them in heavy rain or hosing them down directly.
