The best Cordless joint cleaners, compared.
Top pick: Einhell GE-CC 18 Li kit – Battery, charger and both brushes at about £83.65, with 4.5 from 47 reviews. The sample is smaller than the solo listing. Best value: Einhell GC-CC 18 Li solo – About £47.36 with nylon and steel and 4.1 from 3,333 reviews if you already own an Einhell 18 V pack. Updated 21.10.2026.
A cordless joint cleaner is a battery brush on a shaft that spins in the gap between slabs or blocks and pulls out moss, seedlings and loose dirt. In the UK it is also sold as a patio cleaner, a grout cleaner or a weed sweeper. That sample is much smaller than the solo listing’s 3,333. The bare price is not a working kit. Steel clears robust concrete and brick and will mark sandstone. The brush does not kill a deep root, and it takes jointing sand with the weed, so block paving needs kiln-dried sand brushed back once the surface is dry. Which head suits which stone is set out in the [wire or nylon guide](/hub/garden-tools/cordless-joint-cleaner/sub/cordless-joint-cleaner-wire-or-nylon). Buyers are people who are finished with kneeling on a patio, a path or a block-paved drive. A surface roller, a pressure washer, a weeding knife and a drill-mounted brush are different objects and sit outside this table.

Personal buying guide
Question 1 of 2
Which battery do you already own?
The Einhell GE-CC 18 Li kit is listed at £83.65 with a Power X-Change battery, a charger, a nylon brush, and a steel brush, and a 100 mm cutting width. The amazon.co.uk line is 4.5 from 47 reviews; this file holds 11 UK texts, and they say it does the weed job, including after a strim, with one older user finding it light enough. One buyer finished a herringbone driveway on the early sessions without a recharge, and straight joints are described as quicker than herringbone brick. The limit in those 11 texts is spare parts: a replacement wire wheel is treated as an Einhell-only buy, and one reviewer prices that wheel at £13.52. Rpm and item weight are not printed on this listing, so you cannot quote a speed from the page. No repeated breakage shows up in the 11 reviews. It is the top pick in this set on that score, with the caveat that 47 reviews is a much smaller sample than the solo listing’s 3,333.
Pros
Cons
Best for: A first Einhell patio kit when you want the charger in the box and can live with a small review sample.
Less suitable: You want a large UK review base, a printed rpm figure, or a cheap spare wire wheel.
Specifications
Common questions
Is a battery included with the Einhell GE-CC kit?
Yes. The title says with battery and charger, and the style name is + Battery & Charger. The bullets describe a Power X-Change lithium-ion pack.
What speed does the GE-CC kit listing print?
This file does not print rpm. The cutting-width line says 100 mm, and the bullets include one nylon brush and one steel brush.
How many UK reviews are on the GE-CC kit?
The listing line is 4.5 from 47 reviews. The saved listing contains 11 UK review texts, a much smaller sample than the solo listing.
The Ryobi RY18PCA-0 is listed at £83.95 as a bare ONE+ tool with a wire brush only, at 1,350 rpm and 2.9 kg, and 4.3 from 1,787 reviews. Buyers who already own the battery describe a large cut in kneeling time; one puts hands-and-knees time at about a quarter. The included head is steel, and reviews say it marks brick; the gentler nylon head is a separate buy that those reviewers put at about £15 to £18. One review calls battery life about 20–30 minutes, including on a small test pack, which is a different figure from the listing’s “over an hour” on a 4.0 Ah RB1840X that is not in the box. The head wanders in narrow gaps, throws debris back, and clogs with damp soil. A first-time buyer who also needed a battery and a charger itemises a total above £250. It fits a ONE+ shed that can add a nylon head for softer faces, and it is a poor first purchase if you own no Ryobi pack.
Pros
Cons
Best for: A ONE+ owner with a pack already charged, working concrete or brick and willing to buy nylon for softer stone.
Less suitable: Sandstone or a first Ryobi purchase, and narrow joints where the head wanders.
Specifications
Common questions
Is a battery included with the Ryobi RY18PCA-0?
No. The title says battery and charger excluded. A bullet claims over an hour with a 4.0 Ah RB1840X and says that battery is not included.
Is a nylon brush in the Ryobi box?
Included components are one patio cleaner and one wire brush. A nylon head is not in that line. The wire wheel is printed at 1,350 rpm. Ryobi sells nylon separately for softer stone.
What is the 2 milliamp hour field on the Ryobi listing?
The battery-capacity line prints 2 milliamp hours. The voltage line prints 18 V and the runtime bullet names a 4.0 Ah pack. Treat the milliamp line as a bad catalogue field.
Parkside’s 20 V patio cleaner is a bare tool at £108.99, with no battery or charger, both heads at 110 mm, and 1,200 rpm on the listing. It names natural stone, concrete, tiles, wood, and wood composite, and it says the manual decides which brush. The item-weight field is 2.52 kg and a bullet says about 2 kg; the guide rail is about 103–123 cm. The listing shows 4.2 from 8 reviews, and the five UK texts in the file are short praise: knees saved, useful on paving slabs, and no fault named. None of those five mentions runtime, brush wear, or a marked surface, so you do not have a review pattern for sandstone or a long drive. At this price, without a pack, it only makes sense if a Parkside X 20 V battery is already in the shed. Eight reviews is too small a sample to treat the stars as settled.
Pros
Cons
Best for: A household that already owns a Parkside X 20 V pack and wants both brush types on the shaft.
Less suitable: A first cordless kit, or anyone judging sandstone safety from these eight reviews.
Specifications
Common questions
Does the Parkside patio cleaner come with a battery?
No. The bullet says delivery without battery and charger, and that it fits Parkside X 20 V Team batteries.
Which surfaces does the Parkside listing name?
The title and bullets name natural stone, concrete paving, tiles, wood, and wood composite, and say you should follow the manual for which brush. Both heads are 110 mm.
What do the eight Parkside reviews say?
The listing line is 4.2 from 8 reviews. The file has five short UK reviews, all praise, and none of them names a fault, a runtime, or a marked surface.
Across 3,333 amazon.co.uk reviews at 4.1, the Einhell GC-CC 18 Li solo (model 3424050) is listed at £47.36 without a battery or charger, with a nylon brush, a steel brush, a guide wheel, and 1,200 rpm. Buyers who already own a Power X-Change pack say it clears moss, weeds, and algae from slab gaps faster than kneeling with a scraper, and several note that a strimmer battery fits. The same reviews say a large or neglected block-paved area is still slow, and that the head sits on top of weeds when the joint is narrower than the brush. The two-point trigger is called hard to squeeze, and on one drive the metal head was too aggressive, so those buyers stayed on nylon. Replacement brushes are called expensive. At 2.04 kg on the item line it is a light shaft once the pack is already on the shelf. It is the best value here when you already have an 18 V Einhell battery, not a first kit.
Pros
Cons
Best for: A patio or path owner who already has an Einhell 18 V Power X-Change battery and wants both brush types.
Less suitable: A first kit with no Einhell pack, or narrow block joints where the head only spins on the weed.
Specifications
Common questions
Does the Einhell GC-CC solo include a battery?
No. The title says without battery, and the bullet says it is supplied without a battery or charger. It is a Power X-Change tool, so an existing Einhell 18 V pack fits.
Which brushes come with the GC-CC solo?
The included-components line lists one nylon brush and one steel brush. The cutting-width line says 10 cm.
What speed and switch does the solo listing print?
Speed is 1,200 rpm. The bullets name a two-point safety switch, a telescopic handle, a second Softgrip handle, and a guide wheel.
Einhell’s GC-CC 18 Li kit, model 3424051, is listed at £75.95 with a battery, a high-speed charger, a nylon brush, and a steel brush, at 2.4 kg and 4.0 from 2,187 reviews. Reviewers who keep the weeds small say a large block-paved area can drop from a day of kneeling to about an hour. Battery life is the repeated limit: one large drive needed three charges, and several texts call the tool under-powered once the roots are established. The pass throws out more jointing sand and soil than some buyers expected, so that sand has to go back in. Guard screws are described as fiddly because access is tight. Catalogue lines also print “Item Form Wipe” and “18 litres”, which do not match a paving scraper. It suits a first Power X-Change kit if you accept a short runtime on a big drive, and it is a weaker match if the joints are already full of deep weeds.
Pros
Cons
Best for: A first 18 V Einhell kit for slab gaps and light moss, if you can recharge on a large drive.
Less suitable: Deep-rooted weeds, or a buyer who needs the sand to stay in the joints.
Specifications
Common questions
Does the GC-CC 18 Li kit include a charger?
Yes. Included components list a paving scraper, a battery, a charger, operating instructions, and safety instructions. The bullet adds a LED charge indicator on the battery.
Which brushes are supplied with model 3424051?
The bullets say one nylon brush and one steel brush, both replaceable, plus a telescopic handle, a Softgrip second handle, a guide wheel, and a two-point safety switch.
Why do some catalogue lines look like a liquid cleaner?
The file also prints Item Form Wipe, Contains Liquid Contents Yes, and Item Volume 18 litres. The title, model 3424051, and brush bullets describe a cordless paving scraper. Those liquid lines are catalogue noise.
The Ark Mat Lazy-Weeder is listed at £74.95 with its own 18 V battery, a charger, a metal brush, and a nylon brush. The amazon.co.uk line is 3.9 from 135 reviews. Buyers who get it built say it saves bending on ordinary patio growth, though the title’s 2 kg and the technical line’s 3.5 kg cannot both be the working weight. Reviews say it arrives in pieces, the instructions are tiny, and the handle screw takes working out. The battery runs out quickly, the brushes are called poor quality, and on one unit the wire brush would not release; a replacement sent by the seller did not fit, so the tool was returned. It skids on tough grass and, for at least one buyer, does not get down between pavers. Choose it when you want a complete own-brand kit at this price and can spend time on assembly, not when you need a shared 18 V shelf.
Pros
Cons
Best for: A buyer who wants battery and charger in one box and only light patio growth.
Less suitable: You already own Einhell or Ryobi batteries, or you need a brush that reaches narrow paver gaps.
Specifications
Common questions
Are the Lazy-Weeder battery and charger in the box?
Yes. Separate bullets say a rechargeable 18 V lithium-ion battery and a charger are included, plus a metal brush and a nylon brush.
Which Lazy-Weeder weight should you read?
The title says lightweight 2 kg. The technical details line says 3.5 kg and dimensions 120 × 15 × 92 cm. Both figures are printed in the file.
Does the Lazy-Weeder listing print a speed?
No rpm is printed. The bullets do name a transparent safety guard and a guide wheel.
The NETTA 12 V weed sweeper is listed at £69.99, 1,200 rpm, and 2.4 kg, with a handle that extends from 1 m to 1.22 m, and 3.7 from 180 reviews. The title says a steel brush and two nylon brushes; a bullet says two 10 cm brushes, one nylon and one steel, so the box count is not settled on the page. Reviews say a charger is supplied even though the bullets do not print that word, and they call the tool light and easier on the back. Runtime is the repeated complaint: buyers report about 18 minutes, about an hour, and a charge of roughly four hours, against an 80-minute figure one reviewer says the listing claimed. It is weak on substantial grass, the trigger is called awkward, and the battery indicator is not visible. One buyer says it reaches about 2 inches down on block paving. It is a self-contained 12 V option around £70 if your weeds are small, and a poor match if you wanted a shared 18 V pack or a long session on one charge.
Pros
Cons
Best for: A small patio with light weeds when you want a charger in the parcel and no 18 V platform.
Less suitable: A large drive, established grass, or a shed that already runs Einhell, Ryobi, or Parkside packs.
Specifications
Common questions
How many brushes does the NETTA listing claim?
The title says a steel brush and two nylon brushes. A bullet says two 10 cm brushes, one nylon and one steel. Both lines are in the same file.
Does a charger come with the NETTA sweeper?
The bullets do not print the word charger. UK reviews in the file say the charger is supplied and that charging can take about four hours.
What handle length does NETTA print?
The telescopic bullet says the handle extends from 1 m to 1.22 m. Item weight is 2.4 kg and the speed bullet says 1,200 rpm.
Sealey’s CP108VJC is listed at £96.47 as a 10.8 V SV10.8 kit with a 2 Ah battery, a fast charger, and 100 mm nylon and metal brushes, at 3 kg. The bullets name weeds and moss in patio cracks and block paving, and the assembly line says No. This amazon.co.uk file has no customer-review line and no UK review text, so there is no star rating and no report of runtime, marks, or spare brushes. The score is 0 for that reason, not because a test failed. A 2 Ah pack on a 10.8 V platform is a smaller energy store than the 18 V kits in this set, which matters on a large drive, though the listing does not print minutes. It is a complete trade-style kit if you already use SV10.8 batteries. It is the listing to skip if you want buyer reports before you spend about £96.
Pros
Cons
Best for: A workshop that already runs Sealey SV10.8 batteries and wants both heads in one kit.
Less suitable: Anyone who wants amazon.co.uk reviews before buying, or a long session on a big drive.
Specifications
Common questions
What is in the Sealey CP108VJC kit?
The bullets list the CP108VJC body, a CP108VBP 10.8 V 2 Ah battery, a fast charger, a 100 mm nylon brush, and a 100 mm metal brush.
Does the Sealey file show a star rating?
No. There is no customer-review line and no UK review text, so the rating is not shown. The score on this page is 0 for that reason.
Is assembly required on the Sealey kit?
The assembly line says No. The bullets also say the telescopic handle is height-adjustable and that the tool clears weeds and moss from patio cracks and block paving.
Eight amazon.co.uk listings, saved on 19 October 2026, were scored as the star rating times 20. That score is not a laboratory scratch or runtime test. The Einhell GE-CC 18 Li kit scores 90 from 4.5 and 47 reviews, so it is the top pick, with the small sample stated in the write-up. The Sealey kit scores 0 because the file has no review line. Best value is the Einhell GC-CC 18 Li solo at about £47.36, with nylon and steel and 4.1 from 3,333 reviews, not a bare price that still needs a pack or the right head.

Value in this set
10%Best value is the Einhell solo at about £47.36 with both brushes and 4.1 from 3,333 reviews, if you already own a Power X-Change pack. A bare-tool price is not a working kit.
Choose a cordless joint cleaner by the battery you already own, the head the stone will tolerate, and whether the brush is narrow enough for the joint. A bare price is the motor, not a working kit. Steel clears robust concrete and brick and will mark sandstone. The table above is the eight amazon.co.uk listings saved on 19 October 2026. The notes below are the trade-offs from those files and from public UK paving and machinery guidance. None of the scores is a laboratory scratch test.
A cordless joint cleaner is a battery brush on a shaft. It spins in the gap between slabs or blocks and pulls out moss, seedlings and loose dirt. In the UK the same tool is sold as a patio cleaner, a grout cleaner or a weed sweeper. Buyers are people who are finished with kneeling on a patio, a path or a block-paved drive. A surface roller, a pressure washer, a weeding knife and a drill-mounted brush are different objects and sit outside this table. Three layouts are in these eight listings.
The Einhell solo, the Ryobi RY18PCA-0 and the Parkside cleaner do not include a pack or a charger. One Ryobi review describes those as three orders, and a first outfit can sit above £250. Ryobi’s own site lists the bare tool at £121.99, which is not the amazon.co.uk line of about £83.95.
Steel will mark sandstone. Nylon is the head Einhell and Ryobi specify for scratch-sensitive surfaces. The Weed Guy puts block-paving joints at about 2–5 mm and a powered head at about 8–15 mm. A wider brush sits on the weed and spins. That complaint is in the Einhell UK reviews.
The brush takes jointing sand with the weed. Marshalls says replace that sand, and Pavingexpert ties empty joints to lost interlock. Brush kiln-dried sand back once the surface is dry. Ryobi states 32 minutes on 2.0 Ah and up to 80 minutes on 5.0 Ah. Reviewers on the bare file often say about 20–30 minutes. Do not merge those into one number.
A bare listing is the motor and the heads named on the page, not a working kit. The bare tools here are the Einhell GC-CC 18 Li solo at about £47.36, the Ryobi RY18PCA-0 at about £83.95 and the Parkside 20 V cleaner at about £108.99. Each needs its own family: Power X-Change 18 V, ONE+ 18 V, or Parkside X 20 V. One Ryobi review treats the tool, the battery and the charger as three orders, and a first outfit is itemised above £250.
Steel is for concrete, brick and robust blocks. Nylon is for soft stone, and only nylon where a listing allows wood or wood-plastic composite. Steel will mark sandstone. Einhell, Parkside, the Lazy-Weeder and Sealey include nylon and metal. The Ryobi bare listing includes wire only, and reviews put a separate nylon head at about £15 to £18. Ryobi sells that head for sandstone, limestone, porcelain and tile.
Three typical situations, each with a recommendation from this comparison.
You already have an 18 V Power X-Change pack. The GC-CC 18 Li solo at about £47.36 is the best value: nylon and steel, 1,200 rpm, and 4.1 from 3,333 reviews. The battery is not in the box. UK reviews say a wide head sits on a narrow joint.
You need the charger in the parcel. The GE-CC 18 Li kit at about £83.65 is the top pick: battery, charger, nylon and steel, a 100 mm width, and 4.5 from 47 reviews. Rpm is not printed, and 47 reviews is a small sample beside the solo listing.
You already own a Ryobi ONE+ pack and the surface is concrete or brick. The RY18PCA-0 at about £83.95 is a bare tool with a wire brush at 1,350 rpm and 4.3 from 1,787 reviews. Nylon is a separate buy. Skip it for sandstone.
The top pick is the Einhell GE-CC 18 Li kit at about £83.65. The numeric score is the amazon.co.uk star rating times 20, so 4.5 from 47 reviews is 90, ahead of the Ryobi at 86. The kit leads because the box holds a Power X-Change battery, a charger, a nylon brush and a steel brush. That review file is much smaller than the solo listing, and the page does not print rpm or weight. The best value is the Einhell GC-CC 18 Li solo at about £47.36, 4.1 from 3,333 reviews, sold without a battery. Buy it when a Power X-Change pack is already on the shelf. A bare price is not a working kit, steel will mark sandstone, and none of these scores is a laboratory scratch test.
