The best Einhell cordless lawnmowers, compared.
Top pick: Einhell GE-CM 18/33 Li solo Best value: Einhell GE-CM 18/30 Li kit – 4.2 from 9,541 reviews, listed at £83.94 with a 3.0 Ah pack, the lowest kit price in that group. Updated 22.10.2026.
A cordless lawnmower is a walk-behind rotary that cuts on a battery pack rather than a cable or a petrol engine. You buy one in the UK for a short session on a small or mid-size lawn. The checks that still apply if the models change are whether a pack and a charger are named in the box, whether the deck takes one pack or two, and whether the width, bag and height lines on the same page agree. A one-pack deck suits a small lawn. A twin-pack deck uses two matching packs and is sold as the higher voltage. Widths run from a narrow deck to a wider one around 40 cm. A grass box only counts when the page does not also say there is no bag. A square-metre line is a claim, not a timed test. At a cutting width of 50 cm or less, the outdoor-noise rules cap Stage II sound power at 96 dB. How to read the box before you pay is set out in the [cordless lawnmower buying guide](/hub/lawn-and-garden-equipment/einhell-cordless-lawnmower/sub/einhell-cordless-lawnmower-buying-guide).

Question 1 of 2
Do you already own Power X-Change packs?
The GE-CM 18/33 Li solo is £119 with no pack in the box, and its 4.6 from 968 reviews is the highest star line in this set with a sample large enough to read. Bullets, bag and heights agree: 33 cm, a 30 litre box, five central steps from 25 mm to 65 mm, and up to 200 m² as a listing recommendation. UK reviewers who will not push a petrol mower call it light, easy to assemble, and a good cut on two small lawns, especially if Power X-Change packs are already owned. Several say one pack does not finish a front and a back lawn, so a second charged pack is the pattern they describe, not a measured runtime. The handle unit is called rickety, and grass-box hooks are hard to find next to a Gardena box one buyer already knew. The dimension cell prints 47.6 x 17.3 x 38.6 cm, which is implausibly small for a mower with a handle, and assembly is marked Yes. It does not take the top-pick mark, because the box has no battery, even though the raw score is 92.
Pros
Cons
Best for: You already own at least one Power X-Change pack, and preferably a second, for two small lawns.
Less suitable: You need a battery in the carton, or one pack to finish a front and a back in the pattern those reviews describe.
Specifications
Common questions
Does this 33 cm solo include a battery?
No. The included line is the GE-CM 18/33 Li and the operating instructions. The style name is Mower Only.
What bag and heights do the bullets agree on?
A 30 litre grass box and five central heights from 25 mm to 65 mm. The bullets also say lawns up to 200 m².
Do UK reviews say one battery is enough?
Several say a second charged pack is the practical pattern for a front and a back lawn. That is review comment, not a measured runtime.
The GE-CM 18/32 C Li BL solo is a 32 cm brushless body at £149.95, the same sticker as the 18/33 kit, with a 27 litre container and no pack. Heights are five central steps from 25 mm to 65 mm, and one bullet prints both 180 m² and 270 m². The star line is 4.6 from 20 reviews, which ties the 18/33 solo on the raw score and loses on sample size. The review blocks in the file are from Germany, Italy, Sweden and France, not the United Kingdom, so comments about edge tidying and a 4 Ah pack are not UK opinion. The bullets say the Power X-Change battery and charger are sold separately. Warranty and dimensions were left blank in the capture. Treat the 4.6 as a thin line on a body you still have to power, not as a winner.
Pros
Cons
Best for: You already own a Power X-Change pack and you accept a 20-review line that is not UK text.
Less suitable: You want a UK review sample, a battery in the box, or a single area figure.
Specifications
Common questions
Does the GE-CM 18/32 C include a battery?
No. The bullets say the Power X-Change battery and charger are available separately. The included line names the cordless lawn mower.
Are the 20 reviews from the United Kingdom?
The star line is the amazon.co.uk figure, 4.6 from 20. The review blocks in the file are not from the United Kingdom.
What width, bag and height does the listing state?
32 cm, a 27 litre container, and five central heights from 25 mm to 65 mm. The area bullet says both 180 m² and 270 m².
The GE-CM 18/30 Li solo is £89.99 for a 30 cm brushless body and a 25 litre bag, with no pack and no charger in the included line. In this 19 October 2026 capture it costs more than the 18/30 kit that includes a 3.0 Ah battery. Stars are 4.4 from 3,107 reviews. UK reviewers treat it as a light replacement for a heavy petrol mower on a small lawn when Einhell packs are already in the shed, and one buyer with limited mobility used it on an overgrown patch. The bullets say up to 150 m² and three heights from 30 mm to 70 mm, while the minimum-height cell says 30 centimetres, so that row stays unresolved. Reviewers say the box needs emptying several times or the motor stops, and one calls the grass bin worse than a Flymo. One review warns that batteries from an advertised strimmer bundle did not fit, another found no English assembly sheet, and the power-source cell is printed in French. Pay this solo price only if a compatible 18 V pack is already charged.
Pros
Cons
Best for: You already own a Power X-Change 18 V pack and want the 30 cm body.
Less suitable: You are buying your first Einhell battery, or you need the height cell and the bullets to agree.
Specifications
Common questions
Does the 18/30 solo include a battery?
No. The bullets say the product comes without a battery or charger and that a starter set is sold separately. The included line names only the cordless lawn mower.
How does the price compare with the 30 cm kit in this capture?
This solo is £89.99. The GE-CM 18/30 kit on B078H242FN is £83.94 and includes a 3.0 Ah pack and a charger.
What height is printed?
The bullets say three settings from 30 mm to 70 mm. The minimum-height cell says 30 centimetres. Those two lines do not agree.
The RASARRO 36/34 kit is £237.99 with two 3.0 Ah Plus packs, two chargers and a safety key. Bullets say 34 cm, a 30 litre basket, five heights from 25 mm to 65 mm and lawns up to 300 m², while the cutting-width cell says 36 cm and the minimum-height cell says 25 centimetres. Einhell.co.uk for 3413222 says 34 cm and a brush motor, and the amazon bullets do not say brushless. Stars are 4.4 from 2,005 reviews, the highest star line among the kits in this set that include a battery and at least 500 reviews, which is why it carries the top-pick mark. UK reviewers call it lighter and quieter than a long-owned petrol mower, and some say two packs finish a front and a back, including a slope, without a cable. Gardeners' World states about 30 minutes on a RASARRO they tested, at their own prices, which is not a time from this comparison. Instructions are a repeated complaint, one updated review says the safety cut-out failed after a few uses, and a review title names a RASARRO 36/38, a different width string. The included line does not name a mulch wedge.
Pros
Cons
Best for: You want two packs in the box for a wider pass and you will treat 34 cm as the bullet and the maker page, not the 36 cm cell.
Less suitable: You need a mulch wedge, a brushless claim on the amazon bullets, or a width cell that matches the title.
Specifications
Common questions
What is in the RASARRO box?
The included line names the mower, two 3.0 Ah Plus batteries, two chargers and a safety key. It does not name a mulch wedge.
Is the cutting width 34 cm or 36 cm?
The title, the style name and the bullets say 34 cm. The cutting-width cell says 36 centimetres. The minimum-height cell says 25 centimetres, while the bullets say 25 mm to 65 mm.
Do the amazon bullets say the motor is brushless?
No. Brushless is not stated on this listing. A spec cell says battery average life 30 minutes. That cell was not timed here.
The GP-CM 36/41 Li solo is £249 for a 41 cm body with a catch box and no batteries, and the bullets require two 18 V Power X-Change packs, so this is not a ready-to-mow price. The highlight says up to 500 m², a 50 litre collector and 25–75 mm in six steps, while the included line says a catch box without stating litres. There is no cutting-width specification row beyond the 41 cm title, and the listed weight is 16.2 kg. Stars are 4.4 from 956 reviews, and only a minority of the review blocks are from the United Kingdom. Those UK comments call it heavy, say the handle is not balanced in the middle, and mention handles coming loose. One review says it coped with grass left for several weeks and another prefers it to a 33 cm Einhell, while a different comment says it lacks power in long grass or on a short cut. A marketplace unit is described as faulty, with no replacement once the promotion ended. Buy the body only if two compatible packs are already on the shelf.
Pros
Cons
Best for: You already own two Power X-Change packs and you want a 41 cm body.
Less suitable: You need a ready-to-mow kit, a light push, or a collector size that the included line states in litres.
Specifications
Common questions
Does the 41 cm GP-CM include batteries?
No. The bullets say two 18 V Power X-Change batteries are required and that delivery does not include a battery or a charger.
What collector size is printed?
The highlight says a 50 litre collector. The included line says a catch box. The bullets do not state litres.
How wide is it?
The title says 41 cm. There is no cutting-width specification row. The highlight also says up to 500 m² and 25–75 mm.
The GE-CM 18/32 Li solo shares the £83.94 sticker with the 30 cm kit, but the style name says the battery and charger are not included. The cut is 32 cm with a 25 litre box and three heights from 30 mm to 70 mm, and stars are 4.4 from 518 reviews, a smaller sample than the 30 cm kit. UK reviewers call it light and not too loud on a small lawn, and one says a 4.0 Ah pack they already owned finished their patch with charge left. A pull-out key is used as a lock by one buyer. The same sample complains that the battery is hard to unclip until it suddenly releases, and that the grass-box handle pulls out when the box is full. One reviewer at 5 ft 10 in found the handle low, and another called it the weakest Einhell tool they own, fit only for a very small patch. One UK review says a wheel spring broke and then the height lever failed inside two years. A bullet says lawns up to 200 m², the highlight says up to 250 m², and the dimension cell prints 47 x 14 x 39 mm.
Pros
Cons
Best for: You already own a 4.0 Ah Power X-Change pack and the lawn is a very small patch.
Less suitable: You need a battery in the box, a taller handle, or a sample larger than 518 reviews.
Specifications
Common questions
Does the 32 cm GE-CM 18/32 Li include a battery?
No. The style name says the battery and charger are not included, and the included line names only the cordless lawnmower.
Which area figure is on the page?
A bullet says lawns up to 200 m². The highlight says up to 250 m². Both are listing lines.
What are the cutting heights?
Three steps from 30 mm to 70 mm. The height cells match the bullets.
The GE-CM 18/33 Li kit is £149.95 with a 4.0 Ah pack and a fast charger, a 33 cm cut and five heights from 25 mm to 65 mm. It is 4.3 from 7,288 reviews, and rank 460 in Garden on this capture. UK reviews describe it as quieter than a mains mower, light enough to carry, and useful on an allotment where the height range matters, with one comment saying a single charge covered a front and a back on what the writer calls an ordinary garden. The same page contradicts itself: a mulching bullet says there is no collection bag and that grass leaves by side discharge, while the highlight says a 30 litre grass box. Einhell.co.uk for article 3413260 lists a 30 litre box, so the bag stays unsettled rather than resolved either way, and the highlight also says up to 20 m² while another bullet says up to 200 m². A unit bought in May 2026 stopped with the pack apparently fine and was returned, and one buyer finds the battery fiddly to slide. The Which spec table prints 15 minutes for the GE-CM 18/33 Li, which is their figure, not a runtime measured for this comparison.
Pros
Cons
Best for: You want a 33 cm kit with a 4.0 Ah pack and you will check the live bag line before you rely on collection.
Less suitable: You need the grass box and the area figure to agree on the page you are buying.
Specifications
Common questions
Does the GE-CM 18/33 kit include a battery?
Yes. The included line names a 4.0 Ah Power X-Change battery, a fast charger, the mower and the instructions.
Does the listing include a grass box?
The mulching bullet says the mower is supplied without a collection bag and that grass leaves by side discharge. The highlight on the same page says a 30 litre grass box. Both lines are in the capture.
What area does the page print?
One bullet says lawns up to 200 m². The highlight says up to 20 m². Neither figure was measured for this comparison.
The GE-CM 36/36 Li kit is the dearest sticker in this set at £259.99, with two 4.0 Ah packs and two chargers. Bullets say 36 cm, a 40 litre basket, six heights and lawns up to 400 m², the maximum-height cell says 75 mm, and the minimum cell says 3 centimetres. Stars are 4.3 from 1,867 reviews. One UK review says a long uneven lawn finished on one charge of the two packs, and another says it was light enough to push after a shoulder injury and quieter than a mains mower. A bullet tells you to insert the supplied mulching wedge, while the style name says without a mulching kit, so the wedge stays unresolved. One mower would not start on full packs and was described as sent out faulty, and handle locks on serrated levers do not stay put in that sample. The dimension cell prints 137 x 94 x 4 cm. You are paying the top price in this capture for a wide twin-pack kit whose mulch line does not agree with itself.
Pros
Cons
Best for: You want a 36 cm kit with two 4.0 Ah packs and you will check whether the wedge is actually in the carton.
Less suitable: You need the mulch line to agree, or a lower price than the RASARRO and the 43 cm kit.
Specifications
Common questions
Does the GE-CM 36/36 include batteries?
Yes. The bullets and the included line name two 4.0 Ah Power X-Change batteries and two chargers.
Is a mulching wedge included?
A bullet says to insert the supplied mulching wedge. The style name says Without mulching kit. Both lines are in the capture.
What cutting height is printed?
The bullets say six levels. The maximum cell says 75 millimetres. The minimum cell says 3 centimetres. The bag bullet says 40 litres.
The GE-CM 18/30 Li kit is the £83.94 listing that puts a 3.0 Ah Power X-Change pack and a fast charger in the box with a 30 cm deck and a 25 litre bag. Across 9,541 amazon.co.uk reviews it sits at 4.2, the largest sample in this set, and UK reviewers often describe a light push on a small lawn after a petrol mower. The same pack is praised for running other Einhell tools. Height is three axial steps from 30 mm to 70 mm, and reviewers say you move both axles against a spring. The grass box is a repeated complaint: flimsy, awkward to assemble, and poor at collecting in at least one account. One buyer wanted a shorter cut than the bottom step, and another says the supplied 3.0 Ah pack lasted about 15–20 minutes after a long charge. The bullets do not name a lawn area or a mulch wedge, and nothing here was timed on a lawn. It is the best-value row because the sticker includes a battery at the joint-lowest price in this capture, not because the box or the runtime is generous.
Pros
Cons
Best for: You want a 30 cm kit for a small lawn and you do not already own a Power X-Change pack.
Less suitable: You need a longer run than one 3.0 Ah charge, a cut below 30 mm, or a bag reviewers call sturdy.
Specifications
Common questions
Does this 30 cm Einhell include a battery?
Yes. The included line names a 3.0 Ah Power X-Change battery and a fast charger, plus the GE-CM 18/30 Li and the instructions.
What cutting height does the listing state?
Three axial steps from 30 mm to 70 mm. The bullets and the height cells agree. UK reviews say you move both axles against a spring.
Is it self-propelled?
The bullets do not say it is self-propelled. The operation cell says Automatic, which is not a drive type.
The GE-CM 43 Li M kit is £239.94 for a 43 cm deck, a 63 litre bag, a mulching wedge named in the bullets, and two 4.0 Ah packs with two fast chargers. Heights run from 25 mm to 75 mm in six steps, a bullet says lawns up to 600 m², and a spec cell says battery average life 60 minutes, which was not mown for this page. Stars are 4.1 from 6,758, the lowest average in the set on a large sample. UK reviewers describe it as lighter than a Hayter or Mountfield petrol mower and quiet, and one buyer ordered a second after four years. The grass catcher is hard to assemble in the sample, one review says it will not cut a week’s growth on the lowest setting, and another says two or three weeks of growth empties the pack in about 10 minutes. The bullets do not say self-propelled, although some UK reviews praise that feature, so the comparison stays with the bullets. Assembly is marked No while the included list names screws, brackets and a push bar.
Pros
Cons
Best for: You want the widest cut and the largest bag in this set, with two packs in the box, and you accept a 4.1 average.
Less suitable: You need the highest star line, a confirmed self-propelled drive, or a short cut through a week of growth.
Specifications
Common questions
What comes with the 43 cm Einhell?
The bullets name two 4.0 Ah batteries, two fast chargers, a 63 litre bag and a mulching wedge. The included list also names push-bar brackets, a safety plug, clips and screws.
Is it self-propelled?
The bullets do not say self-propelled. Some UK reviews on this ASIN praise a self-propelled feature. The comparison cell stays with the bullets.
What runtime does the listing print?
A spec cell says battery average life 60 minutes, and a bullet says lawns up to 600 m². Neither figure was measured here.
Ten amazon.co.uk listings are scored in this folder. Products Compared did not mow a lawn. The method note publishes no separate percentage split. The stored score is the amazon.co.uk star rating times 20, so that single rule is the whole score and is recorded at 100 below. A 4.4 line is 88 is a worked example for one listing, not a criterion weight, and it is not used as a weight. No partial weights were rescaled. Whether a battery is in the box, review count, a listing conflict and price sit in the assessment, not as a second penalty inside the number. A maker square-metre line stays a claim.
Amazon.co.uk star rating
100%The stored score is the amazon.co.uk star rating times 20. A 4.4 line is 88. A 4.2 line is 84. A 4.6 line is 92. It is not a lab test and not an editorial rank. A battery in the box, review count, listing conflicts and price stay in the written assessment. The method note prints no other percentage. The figure 88 is a worked example for one product at 4.4 stars, not a criterion weight.
Decide whether a pack is in the box, then whether the deck takes one pack or two, then whether the width, bag and area lines agree. Ten amazon.co.uk listings are on this page. The stored score is the star rating times 20. It is not a mown test of runtime, noise or cut quality.
A cordless lawnmower in this set is a walk-behind rotary on the Power X-Change system. The deck is either one 18 V pack or two packs in a body sold as 36 V. Einhell’s UK battery page describes 36 V as two 18 V packs. A Ryobi or Bosch pack does not fit. Ten amazon.co.uk listings stayed after a Ryobi body and a Litheli mower were removed. Prices in the 19 October 2026 captures run from £83.94 to £259.99. Nothing here was mown. Start with the box.
The 18/32 solo matches the 18/30 kit at £83.94 and does not include a battery. The 18/32 C matches the 18/33 kit at £149.95 and does not include one either. The 41 cm body at £249 still needs two 18 V packs. Add the packs before you call a solo cheaper.
Einhell’s UK battery page describes 36 V as two 18 V Power X-Change packs. A Ryobi or Bosch pack does not fit. A one-pack deck is the 18/30, 18/32 or 18/33. The RASARRO, the 36/36, the 43 cm and the 41 cm use two packs.
The 18/33 kit says no bag and side discharge in a bullet, and 30 litres in the highlight. Einhell.co.uk lists a 30 litre box, so the bag stays unsettled. The RASARRO amazon bullets do not say brushless. Einhell.co.uk calls that motor a brush motor. Do not treat 20 m² or 60 minutes as a test.
The first check is whether a pack and a charger are named in the included line. Kits in this capture are the GE-CM 18/30 at £83.94 with a 3.0 Ah pack, the GE-CM 18/33 at £149.95 with a 4.0 Ah pack, the RASARRO at £237.99 with two 3.0 Ah packs, the 43 cm at £239.94 with two 4.0 Ah packs, and the 36/36 at £259.99 with two 4.0 Ah packs. Solos are the 18/32 at £83.94, the 18/30 at £89.99, the 18/33 at £119, the 18/32 C at £149.95, and the 41 cm at £249, which still needs two packs.
Use a width only where the page agrees: 30, 32, 33, 36, 41 or 43 cm. The RASARRO bullets and Einhell.co.uk say 34 cm. A specification cell says 36 cm, so that width stays a conflict. The 18/30 files agree on a 25 litre bag and 30–70 mm in three steps. The 18/33 solo agrees on 30 litres and 25–65 mm. The 18/33 kit says no bag and side discharge, and also a 30 litre highlight, plus 20 m² and 200 m². The 18/32 C prints 180 m² and 270 m² in one bullet.
Three typical situations, each with a recommendation from this comparison.
You do not already own a Power X-Change pack and the lawn is small. The GE-CM 18/30 Li kit is the £83.94 listing with a 3.0 Ah pack, a fast charger and a 25 litre bag, at 4.2 from 9,541 reviews. Height is three axial steps from 30 mm to 70 mm. Reviewers call the box flimsy, and one puts that pack at about 15–20 minutes.
You already own at least one 18 V Power X-Change pack, and preferably a second. The GE-CM 18/33 Li solo is £119 with no pack in the box, 4.6 from 968 reviews. Bullets agree on 33 cm, a 30 litre box and 25–65 mm in five steps. Several UK reviews say one pack does not finish a front and a back.
You want two packs in the carton for a wider pass. The RASARRO 36/34 kit is £237.99 with two 3.0 Ah packs and two chargers, at 4.4 from 2,005 reviews. Bullets say 34 cm. A spec cell says 36 cm. The 43 cm kit at £239.94 is the alternative if the 63 litre bag matters more than the 4.1 average.
The top pick is the Einhell RASARRO 36/34 kit: 4.4 from 2,005 amazon.co.uk reviews, score 88, two 3.0 Ah packs and two chargers in the box, listed at £237.99 on 19 October 2026. That is the highest star line among listings that name a battery and a charger and have at least 500 reviews. It is not the highest score, and it is not a claim that it is the best mower in Britain. Best value is the Einhell GE-CM 18/30 Li kit: 4.2 from 9,541 reviews, score 84, listed at £83.94 with a 3.0 Ah pack. The 18/32 solo is the same £83.94 with no battery, so it does not take that badge. The 18/33 solo scores 92 from 968 reviews and has no pack in the box.
Einhell GE-CM 18/30 Li kit
4.2 from 9,541 reviews, listed at £83.94 with a 3.0 Ah pack, the lowest kit price in that group.
