The best cordless lawn mowers, compared.
Top pick: SEYVUM 40V 40 cm Best value: Einhell GE-CM 18/30 Li – Battery included, at least 1,000 reviews, and the lowest price in that group, about £83.94. Updated 22 October 2026.
A cordless lawn mower is a walk-behind rotary whose blade runs from a rechargeable pack. The charger plugs into UK mains, and there is no lead across the lawn. You buy one for a small domestic lawn when you want the cut without a cable underfoot. A kit with a battery in the box is a different buy from a body-only tool, which only makes sense if you already own the pack. Tell a suitable machine by the cutting width, whether a battery and a charger are named, and whether the height lines agree. Width runs from about 30 cm to about 40 cm. A published UK class puts a small lawn under 50 m², a medium lawn at 50–150 m², and a large lawn at 150 m² or more. Collect, mulch, or a rear roller counts only when the listing names it. Packs from different platforms do not interchange. Use an RCD outdoors and check the charger for a BS 1363 plug. The mains alternative is the [cordless or corded guide](/hub/lawn-and-garden-equipment/cordless-lawn-mower/sub/cordless-lawn-mower-vs-corded).

Question 1 of 2
What has to be in the box?
SEYVUM’s 40 cm kit is £159.98 with two 4Ah batteries, a charger, and a 45 L bag, and the height lines agree at 25–75 mm in six steps. The listing is 4.8 from 13 reviews, and the saved listing holds seven UK review bodies. Short reviews say it cuts well and went together easily, and one 80-year-old reviewer managed damp grass at a 1.5 inch cut, with the batteries lasting a 20 minute mow in that account. The grass-box handle did not stay put once it was assembled, and collection failed until a pillar fitting between the mower and the box was removed. Listed weight is 13 kg, which matches the 28.6 lb bullet as a conversion. A bullet’s 1800W figure and a comparison with a 150 cc petrol mower are not measurements in this file. Thirteen reviews can move quickly, so 4.8 is a thin sample beside the Einhell rows with thousands of ratings.
Pros
Cons
Best for: You want the widest deck in this set with two packs in the title, and you treat 13 reviews as a first look rather than a settled record.
Less suitable: You want thousands of reviews, a mulch plug, or a price near the £80 kits.
Specifications
Common questions
What comes in the box?
The title lists a 40V mower, two 4Ah batteries, and a charger. A bullet names a 45 L bag.
How wide is the deck?
The title says 16 inches / 40 cm, and the attribute cutting width is 40 cm.
How many UK reviews are in the file?
The listing line is 4.8 from 13 reviews, and the saved listing contains seven UK review bodies.
Bosch’s ROTAK18V-32 is sold as a kit at £181.00 with an 18V 4.0Ah battery, an AL 18V-44 charger, a 32 cm cut, a 35 L fabric bag, and a mulch plug. The star line is 4.5 from 54 reviews, which is a thinner sample than either Einhell row. Reviewers on small lawns mention a tidy edge and straightforward assembly, and several call it light even though the attribute weight is 14.3 kg. Runtime is the sharp complaint: one review describes charging every 10–15 minutes, and the battery release is titled as needing a redesign. A handle screw that would not tighten also appears in the file. The POWER FOR ALL wording only helps if your other tools already use that 18V system. It is not a bare tool, and the attribute table omits width and height even though the title prints 25–65 mm.
Pros
Cons
Best for: You already own Bosch POWER FOR ALL 18V packs and want mulch or collect on a small lawn.
Less suitable: You are buying a first battery and need a large review sample or a lower kit price.
Specifications
Common questions
Is the Bosch a bare tool?
No. The style name is 1 Battery + 1 Charger, and the included line lists an 18V 4.0Ah battery and an AL 18V-44 charger.
Can it mulch and collect?
The title includes a 35 L fabric grass bag and a mulch plug.
How heavy is it in the capture?
The attribute weight is 14.3 kg.
DEKO’s 38 cm listing is £159.98 and names two 4.0Ah batteries, a charger, a 40 L bag, and a brushless motor, with six heights that agree at 25–75 mm. The customer-reviews line is 4.5 from two reviews, and the saved listing contains no UK review text, so there is no praise or fault pattern to quote. A bullet describes the packs as 2 x 20V 4.0Ah and claims up to 30 minutes, which is a seller sentence rather than a measured run. Weight is unresolved: the attribute says 350 g and the highlight says 12.5 kg, so neither figure should be treated as the mass you will lift. Assembly is required, and a folding handle is listed. Without review bodies, the wide deck and the second pack are catalogue facts. A 4.5 from two ratings is not evidence that it finishes a medium UK lawn.
Pros
Cons
Best for: You want a 38 cm twin-pack listing on paper and will wait for more UK reviews before you trust the stars.
Less suitable: You want review evidence, a settled weight, or a single clear voltage description.
Specifications
Common questions
How many reviews are in the capture?
The customer-reviews line is 4.5 from 2. The saved listing has no UK review text.
What does the listing say it weighs?
The attribute weight is 350 g. The highlight says 12.5 kg. Both are printed, so weight is unresolved.
What is the cutting width?
The title and the attribute table both say 38 cm, with six heights from 25 mm to 75 mm.
The Einhell GE-CM 18/33 Li is 4.3 from 7,288 amazon.co.uk reviews at £149.95, and the box includes a 4.0Ah Power X-Change battery and a fast charger. Reviewers often say it is easier than an old petrol or corded mower on a smaller garden, and at least one calls it quieter than petrol. The listing does not agree with itself: a bullet says it is supplied without a collection bag and uses side discharge, while a highlight says a 30 L grass box, and the area line says both up to 200 m² and up to 20 m². Cutting heights do agree at 25–65 mm in five steps, and the listed weight is 11.2 kg. Runtime is the recurring limit, including one report of about 15 minutes, and the battery can be awkward to seat. One buyer said it stopped after limited use even after the pack was checked, and another called it underpowered on dry, brittle grass.
Pros
Cons
Best for: You want the deepest review sample among kits that include a battery, and you will read both bag lines before you rely on a collector.
Less suitable: You need a confirmed grass box, a mulch plug, or one charge to finish much more than a small lawn.
Specifications
Common questions
Does the Einhell 33 cm include a grass box?
The bullet says it is supplied without a collection bag and uses side discharge. The item highlight on the same listing says a 30 L grass box. Both lines are in the capture, so the box is a listing conflict.
What battery is in the box?
The included-components line names a 4.0Ah Power X-Change battery and a fast charger.
How many UK reviews are on this listing?
The capture shows 4.3 out of 5 from 7,288 reviews.
The Ryobi OLM1833B is listed at £160.20 as Lawnmower Only, with 4.3 from 2,487 reviews, and the title says the battery and charger are excluded. A bullet claims up to 250 m² when you fit an 18V ONE+ 5.0Ah pack, which you have to supply. Owners who already have a 5Ah pack call it light on small or split gardens, and one review finished the lawn and then a strimmer on the same pack. Damp grass blocks or stalls it, and several accounts say it will not take a first cut or medium-long grass. Height lines conflict: bullets say five levels at 25–65 mm, while attributes say a 65 cm maximum and three positions. Weight is 10.3 kg in the table and 7.7 kg without a battery in a bullet. One first unit was faulty and would not run after assembly, so the £160.20 is a body price, not a ready-to-mow price.
Pros
Cons
Best for: You already own Ryobi ONE+ 18V batteries and a charger, and the lawn is a regular trim rather than a spring recovery cut.
Less suitable: You need a mower that cuts on the day it arrives, or a first cut through longer grass.
Specifications
Common questions
Does this Ryobi include a battery?
No. The title says battery and charger excluded, and the style name is Lawnmower Only.
Which battery does the listing expect?
The bullets name the Ryobi ONE+ system and a coverage claim that uses an 18V ONE+ 5.0Ah battery, which is not in the box.
Does it mulch?
A bullet names a 35 L collector and an included mulching plug.
Litheli’s 20V listing is £109.99 with a 33 cm deck, a 5.0Ah battery in the title, a 35 L box, and a 2-in-1 mulch or collect claim, at 4.3 from 684 reviews. UK reviewers often get through a small front and back garden, and several put the runtime at about 25–30 minutes, which lines up with the 30-minute attribute as a seller figure rather than a test. Height does not resolve: the bullets say 25–65 mm and the attribute minimum is printed as 25 centimetres. A charger is not named as a separate included item, and there is no shared-platform line on this 20V page. One supplied battery arrived dead, and a replacement pack would not click into the slot, so that mower stopped mid-lawn. Assembly is a common compliment, and one reviewer said thicker patches and stones were handled. A review title also calls the charge time poor.
Pros
Cons
Best for: A small garden if you want mulch or collect on a 33 cm deck and will confirm a charger is actually in the carton.
Less suitable: You need agreed height figures, a named charger, or a pack that must match another brand.
Specifications
Common questions
Is a charger listed with this Litheli?
The title includes a 5.0Ah battery. A charger is not named as a separate included item in the capture.
Can it mulch?
The bullets describe a 2-in-1 mulch or collect function and a 35 L box.
Do the height figures agree?
No. The bullets say 25–65 mm. The attribute minimum is printed as 25 centimetres.
The Forte 21.6V mower is £99.99 with a 34 cm deck, a 4.0Ah battery, and a charger described as a one-hour fast charger, scoring 4.3 from 82 reviews. It is the only row in this set whose title and a bullet both name a rear roller. Reviewers with limited mobility call it manageable, and the 32 L box is praised in a title, though another review says that box was impossible to construct. The height lines are close but not the same: attributes say 22–72 mm and bullets say 20–70 mm, both with six positions. A recurring fault is a battery that becomes extremely hot and forces a cooling stop, and one buyer wanted a spare pack that is not in the box. A do-not-buy review says the cut is not close, and one session was described as about two hours for a poor result. There is no shared-battery claim, so the 21.6V pack stays with this mower.
Pros
Cons
Best for: You want a rear roller on a kit under £100 and accept that 82 reviews is a modest sample.
Less suitable: You need a mulch plug, a second pack, or height figures that match on every line.
Specifications
Common questions
Does the Forte have a rear roller?
Yes. The title and a bullet both name a rear roller for a striped finish.
What battery is supplied?
The title and bullets name a 21.6V 4.0Ah battery and a charger described as a one-hour fast charger.
Do the cutting heights match?
Not exactly. The attribute table says 22–72 mm and the bullets say 20–70 mm, both with six positions.
Across 9,541 amazon.co.uk reviews the Einhell GE-CM 18/30 Li sits at 4.2 and £83.94, with a 3.0Ah Power X-Change battery and a fast charger in the box. Reviewers mostly use the 30 cm deck on a small lawn and often describe it as lighter and quieter than the corded mower it replaced. The height lines agree at 30–70 mm in three steps, and the 25 L bag is named without a second, conflicting size. Several UK reviews still call the battery the weak part once the grass is more than a trim, and long or wet grass is a repeated struggle. The two halves of the grass box are hard to join for more than one buyer, and the on/off switch is called flimsy. At a listed 9.32 kg with a folding handle it is easy to put away, though one reviewer found even the 30 mm stop not short enough.
Pros
Cons
Best for: A small, often-mown lawn if you want a battery in the box and can live with a 30 cm deck on the Einhell PXC platform.
Less suitable: A lawn that needs a wider deck, a mulch plug, or a cut below 30 mm.
Specifications
Common questions
Does this Einhell come with a battery?
Yes. The included-components line lists a 3.0Ah PXC battery, a fast charger, the GE-CM 18/30 Li, and instructions.
What cutting heights does the 30 cm Einhell list?
The attribute table and the bullets agree on three settings from 30 mm to 70 mm.
Will the battery fit other Einhell tools?
The listing is an 18V Power X-Change kit. It does not say the pack fits Ryobi or Bosch tools.
The LIGO 20V kit is £81.19 with two 2.0Ah batteries, a fast charger, a 33 cm title width, and a 25 L bag, at 4.2 from 89 reviews. Reviewers call it light, including an older user, and one cites a lawn of about 4 x 4 m as the size it suits. Two packs in the box are the practical point on a very small plot, and the listing claims about a 35-minute swap, which remains a claim. The page does not agree on size: the title says 33 cm and three height adjustments, the attribute width is 13.39 inches, the attributes also say five positions at 0.98–2.17 inches, and a bullet says 30–60 cm. One unit smoked in the first minutes and was refunded, another would not turn on, and a lowest setting left grass uncut. The charger is called cheap, a safety key on a string is fiddly in one review, and a return was described as difficult.
Pros
Cons
Best for: A very small lawn, around the 4 x 4 m example in a review, if you accept a thin sample and conflicting height text.
Less suitable: You need agreed cutting figures, a large review count, or one charge on anything bigger than a pocket lawn.
Specifications
Common questions
Are batteries included?
Yes. The title says two 2.0Ah batteries and a fast charger.
What cutting width is printed?
The title says 33 cm. The attribute table says 13.39 inches.
Do the height settings agree?
No. The title says three adjustments, the attributes say five positions in inches, and a bullet says 30 cm to 60 cm.
Litheli’s 40V mower is the dearest listing here at £239.99, with a 37 cm deck, a 40 L box, and two 4.0Ah batteries in the title. The star line is 3.8 from 24 reviews, the weakest sample in the set, and a charger is not named as its own included line. The style field says Brushed. Heights conflict: the bullet lists 25, 35, 45, 55, 65 and 75 mm, while the attributes print 25 cm to 75 cm. UK reviews mention charge times of about 10 hours, a handle that is too high for a shorter user, and packs stuck at 50 percent after three uses. One mower died halfway through a small garden after a year, and a start button became intermittent after winter storage with no support reply in that review. Folded size is given as 70 x 48 x 48 cm, and the U20 claim is not the same voltage as the Litheli 20V row.
Pros
Cons
Best for: You specifically want this 40V U20 listing and will check that a charger arrives with the two packs.
Less suitable: You want the strongest review line, a confirmed charger, or a price under £160.
Specifications
Common questions
How many batteries are in the title?
The title says two 4.0Ah batteries. A charger is not named as its own line.
Is this the same pack as the Litheli 20V mower?
No. This listing is 40V and points at the U20 series. The other Litheli listing is 20V.
What is the amazon.co.uk review line?
3.8 out of 5 from 24 reviews in the capture.
Ten amazon.co.uk listings were scored on 22 October 2026. The score is the star rating multiplied by 20. A 4.3 line is 86. Review count, listing conflicts, a missing charger, and price are not subtracted inside that number. The top pick is the battery-included listing with at least 500 reviews and the highest star line in that group. The best value is the battery-included listing with at least 1,000 reviews and the lowest price in that group. Nothing was mown in a lab.
Amazon star rating
100%The published score is the amazon.co.uk star rating multiplied by 20, on a 100-point scale. A 4.3 line is 86 and a 4.8 line is 96. Review count, listing conflicts, missing chargers, and price are not subtracted inside that number. They sit beside the score. No other criterion percentage is published.
Judge a cordless lawn mower by the battery in the box, the platform, the cutting width, and whether the height lines agree. A seller’s minutes or square metres are a claim. This comparison did not mow a lawn.
A cordless lawn mower here is a walk-behind rotary whose blade runs from a rechargeable pack, with the charger on UK mains and no lead across the lawn. Buyers are mostly cutting small domestic lawns and are choosing between a kit with a battery in the box and a body-only tool that only makes sense if the pack is already owned. Judge a listing by width, whether a pack is included, whether the height lines agree, and how many UK reviews sit behind the stars.
A body-only listing excludes the battery and the charger. The shelf price is not a ready-to-mow price unless you already own that platform’s pack.
Einhell Power X-Change, Ryobi ONE+, and Bosch POWER FOR ALL do not share packs. Litheli 20 V and Litheli 40 V are different nominal voltages. LIGO and Forte name their own packs.
A seller’s “up to 200 m²” or “30 minutes” line is a claim. Which?’s 22-minute average is from a different set of cordless mowers, not these listings. This comparison did not mow a lawn.
The first check is whether a battery and a charger are named in the box. A body-only price is not a ready-to-mow price. In this capture one listing is Lawnmower Only. Every other retained listing names a battery, and some name a charger as its own line while others do not. The second check is the platform. Einhell Power X-Change, Ryobi ONE+, and Bosch POWER FOR ALL do not share packs. Litheli 20 V and Litheli 40 V are different nominal voltages. LIGO and Forte name their own packs.
Cutting width in this set runs from 30 cm to 40 cm. Which? classes small lawns as under 50 m², medium lawns as 50–150 m², and large lawns as 150 m² or more. Maker area lines are claims, including a listing that prints both 200 m² and 20 m². Use heights only when the lines agree. Two rows print 25–75 mm in six steps. Others conflict, including millimetres against centimetres, and those stay unresolved. Collect, mulch, or a rear roller is the next choice.
Three typical situations, each with a recommendation from this comparison.
You have a small lawn you mow often and you want a kit with a battery in the box on a 30–34 cm deck. The Einhell GE-CM 18/30 Li names a 3.0Ah pack and a charger, and the height lines agree at 30–70 mm. The 30 cm deck is the limit once the grass is more than a trim.
Stay on the platform printed on the listing. Einhell Power X-Change, Ryobi ONE+, and Bosch POWER FOR ALL do not share packs. The Ryobi OLM1833B is body only. It fits if you already own ONE+ batteries and a charger. It is not a ready-to-mow price on its own.
A 38–40 cm twin-pack listing is a wider deck, not a deeper record. The SEYVUM row is 40 cm with two 4Ah batteries and a charger in the title, at 4.8 from 13 reviews. Treat 13 reviews as a thin sample beside the rows with thousands of ratings.
The top pick is the Einhell GE-CM 18/33 Li. It includes a 4.0Ah battery and a charger, and it is 4.3 from 7,288 amazon.co.uk reviews, the highest star line among battery-included listings with at least 500 reviews. It is not the highest score in the file. The best value is the Einhell GE-CM 18/30 Li at about £83.94, with a battery in the box, 4.2 from 9,541 reviews, and the lowest price among battery-included listings with at least 1,000 reviews. A cheaper row with 89 reviews does not meet that rule. Each score is the star line times 20. This was not a lawn test.
Einhell GE-CM 18/30 Li
Battery included, at least 1,000 reviews, and the lowest price in that group, about £83.94.
