The best robot lawnmowers without boundary wire, compared.
Top pick: eufy E15 – Largest amazon.co.uk sample in this set, 4.6 from 580, with pure vision and a stated mapping cap under 800 m². Best value: Bosch VISIMOW18V-100 kit – The 18 V 4.0 Ah battery and charger are in the box at about £319. The body-only listing does not take best value. Updated 23 October 2026.
A robot lawnmower without boundary wire stays on the lawn using cameras, satellite positioning, lidar, or a mix of those, instead of a perimeter cable pegged around the grass. In the UK you buy one when you want a short lawn with less weekly effort and you do not want to lay a wire, or repair one later. A suitable listing states a lawn area you can check against your own garden, a navigation method that matches your trees and edges, and a slope figure in a unit you can measure. Degrees and percent are not the same number. A charging station needs an outdoor socket on a 30 mA RCD under BS 7671, and a new socket is an electrician's job. A removable battery charges indoors and will not mow while you are out. The cut is a mulch of small trimmings, so bring the lawn down first and do not take off more than one-third of the grass height in one pass. Edges still need you. The first week is set out in the [setup guide](/hub/lawn-and-garden-equipment/robot-lawnmower-without-boundary-wire/sub/robot-lawnmower-without-boundary-wire-how-to-set-up).

Question 1 of 2
Can you power a dock outside?
The eufy E15, model T2880, is listed at £1,499 on amazon.co.uk with a mapping cap under 800 m² and pure vision, so the bullets name neither a boundary wire nor an RTK station. Across 580 reviews the line is 4.6, the largest sample in this set, which is why the score is 92 and why this row is the top pick here. UK reviews describe maps, stripes and a complete-feeling app, and one setup took about 20 minutes including Wi-Fi and an update. The listing notes a 4G subscription if Wi-Fi does not cover the garden, and reviewers treat where you house the dock as the real decision. Battery average life is printed as 60 minutes, and the weight is 16.2 kg. The specification row says a maximum adjustable cutting height of 3 cm, while the intro bullet uses 3 cm for ground variation, so that field is not a usable height range. It is a poor match for a small lawn you can start by hand, or for a buyer who needs a printed minimum-to-maximum cut.
Pros
Cons
Best for: You want a mapped vision mower on a lawn inside the under-800 m² cap and you can site a dock where the signal reaches.
Less suitable: You have a small lawn with no dock spot, or you need a printed cut-height range from the Amazon row.
Specifications
Common questions
Does it use a boundary wire or an RTK station?
The bullets say pure vision, no boundary wires and no RTK station. 4G is optional if Wi-Fi does not cover the garden.
What lawn does the listing tell you to check first?
Under 800 m² mapping area, mostly flat, variations under 3 cm, and slopes inside the limit in that bullet.
What is the cutting height?
The specification row says maximum adjustable cutting height 3 cm. That row is not a minimum-to-maximum range. Leave it as printed.
The Bosch VISIMOW18V-100 kit, model 06008E1070, is £319 on amazon.co.uk for lawns up to 100 m², with a 16 cm cut and a 20–60 mm height in the title. The box lists the mower, an 18 V 4.0 Ah battery and the AL 18V-44 charger, with no dock and no boundary wire. Across 58 reviews the line is 4.5, so the score is 90. The pack and charger are in the box at this price, which is why it is the best value here. The body-only listing does not take that place, and a 1,000-review gate was not applied. UK reviews describe a quiet random cut you start with three buttons and carry between small lawns. The same reviews say the path misses patches, leaves an edge to strim, and runs until you stop it or the pack dies, because there is no app map. Some buyers find the battery latch hard to release. It will not mow to a schedule while you are out, and the listing prints no slope figure.
Pros
Cons
Best for: You have a lawn around 100 m², no outdoor socket, and you are at home to start a carry-out mower.
Less suitable: You want a dock, an app map, or a machine that runs while you are out.
Specifications
Common questions
Does this listing include a boundary wire?
No. The listing says wire-free Smartvision with no wires and no infrastructure. Included items are the mower, an 18 V 4.0 Ah battery and the AL 18V-44 charger.
Does it dock and recharge itself?
Not on this listing. Charging is the removable battery and the included charger. UK reviews describe placing it on the lawn rather than a base station.
What lawn and cut does the title state?
Lawns up to 100 m², cutting width 16 cm, height of cut 20–60 mm.
The Bosch VISIMOW18V-100 body, model 06008E1001, is £296 and the title says without battery. Included components are the mower only, for the same class of lawn up to 100 m², with a 16 cm cut and 20–60 mm in the title. Across 72 reviews the line is 4.1, so the score is 82. Buyers who already own a Bosch 18 V pack treat the shared battery as the point, and one review cites about four hours on a 4 Ah pack. The listing still has no dock and no wire. More than one review reports a stiff or defective battery latch, and a lawn that is not a plain rectangle confuses it. UK reviews leave about 5 inches to strim. At £23 less than the kit, it is only the cheaper buy if you already own a compatible pack and charger.
Pros
Cons
Best for: You already own a Bosch 18 V pack and charger and want the same carry-out mower as the kit.
Less suitable: You need a complete machine in one box, or a mapped dock that runs on a schedule.
Specifications
Common questions
Is the battery in the box?
No. Included components on this listing are the VISIMOW18V-100 only. The title says without battery.
Is this a different mower from the battery kit?
Same VISIMOW18V-100 class, model number 06008E1001, stated up to 100 m² and 20–60 mm. The kit listing is a different ASIN and includes the 4.0 Ah pack and charger.
Does it need a boundary wire?
The listing says wire-free, with no wires and no infrastructure.
The MOVA ViAX 300, model MVVV1200, is £408.45 with a recommended 300 m², dual vision and a virtual boundary, and no RTK station or signal pole. The listing states a 2–6 cm cut, slopes up to 40%, paths down to 60 cm and obstacles up to 4 cm. Across 58 reviews the line is 4.1, so the score is 82. UK reviews praise an easy app, more than one mapped area and a quiet cut, and some edges were closer than expected. Others still strim, including a gap of about 6 inches after resetting the boundary. One review was unhappy on more than a slight incline, which sits beside the 40% bullet rather than replacing it. The dock wants about a metre of flat surround and solid Wi-Fi, while the specification table does not name a charging station even though reviews describe a dock or housing. Weight is 19.3 kg, and one user reported the battery overheating in hot weather.
Pros
Cons
Best for: You want a mapped vision mower around 300 m² without an RTK mast, and you can give the dock a flat metre and a Wi-Fi signal.
Less suitable: You need a steep slope you can trust from one bullet, or an edge you will never strim.
Specifications
Common questions
Does it need a boundary wire or an RTK mast?
The listing says virtual boundaries, wire-free, with no RTK station and no signal pole.
What area, slope and cut height are stated?
Recommended 300 m². Slopes up to 40%. Paths down to 60 cm. Obstacles up to 4 cm. Cutting height 2–6 cm.
What did UK reviews say about edges?
Some called the edge close enough to skip a strimmer. Others still strim, including a gap of about 6 inches after resetting the boundary.
The WORX Landroid Vision Cloud WR303E is £671.99, and the title does not state square metres, so this row is not the 500 m² or 600 m² WORX. Navigation is cloud RTK with no local antenna and no boundary wire, plus vision and V-SLAM, and the listing says there are no extra cloud fees. Cutting width is 18 cm, weight is 11.1 kg, battery average life is 2 hours, and the warranty text is 2 year manufacturer. Across 38 reviews the line is 4.1, so the score is 82. One buyer mapped in about 20 minutes after a pre-trim and called the setup manageable. The same reviews say it could not follow the path between garage and house, and WORX told that buyer nothing could be done. Edges are weaker than hoped. UK reviews mention a dock that is not itemised in the bullets, and cutting height and slope are not printed.
Pros
Cons
Best for: You want cloud RTK without a garden mast and you will measure your own lawn, because this title prints no square metres.
Less suitable: You need a stated area, a narrow side passage the mower must learn, or a printed cutting height.
Specifications
Common questions
Boundary wire or local antenna?
The listing says RTK from the cloud, without a local antenna or boundary wire, and without extra cloud fees.
What area is printed?
This title does not state a lawn area. Do not copy the 500 m² or 600 m² from the other WORX ASINs.
What do the specification rows give?
Cutting width 18 cm, weight 11.1 kg, dimensions 58 x 46 x 28 cm, battery average life 2 hours, 2 year manufacturer warranty.
The YARDCARE V3 is £369.99 with AI vision and no boundary wire, sold for small to medium gardens and with no square metres printed. Cutting height is 20–60 mm and working noise is about 50 dB on the listing. Across 131 reviews the line is 4.0, so the score is 80. Some UK reviews praise a quiet cut and obstacle avoidance on a small patch, with app or onboard control. Others say it entered borders, stopped with an error every few minutes, or clogged when the grass was long. The 35° figure is a tilt sensor in the safety bullet, not a climbing rating. Charging is not stated as a dock or a removable pack, and magnetic strips are described as a feature without a spare-blade count.
Pros
Cons
Best for: You accept a vision mower whose area is only 'small to medium' and you will watch the first runs for border escapes.
Less suitable: You need a printed square-metre rating, a known dock or battery, or a slope you can measure against a climbing figure.
Specifications
Common questions
Does it need a boundary wire?
The listing says no boundary wire and a faster setup than a cabled robot.
What cut and noise does it state?
Cutting height 20–60 mm. Working noise about 50 dB. A rain sensor and a 35° tilt sensor are in the safety bullet.
What area is it rated for?
The title says small to medium gardens. It does not print a square-metre figure.
The YARDCARE V100 is £349.99 for lawns up to 150 m², with a detachable 4 Ah battery, a 16 cm cut and a 20–60 mm height. The title says without boundary, and the bullets include 2 × 5 m magnetic wires for no-go zones plus blades, not a perimeter cable around the lawn. The listing line is 4.0 from 32 reviews, so the score is 80, but the saved listing holds only two UK review texts, so that star line is not a thick UK sample. Those two texts describe charging, three buttons, leaving it, and obstacle detection on a random pattern. There is no fixed outdoor dock in the included description, and no slope on the specification rows. Do not read the 4.0 as a well-supported fault rate.
Pros
Cons
Best for: You want a carry-out vision mower up to the stated 150 m² and you will lay short magnetic strips only where the mower must not go.
Less suitable: You want a large UK review sample, a scheduled dock, or a printed slope rating.
Specifications
Common questions
Does it need a perimeter wire?
The title says without boundary, and a bullet says no complicated boundary cables. It does include 2 x 5 m magnetic wires to lay as no-go zones.
How do you charge it?
The bullet says charge the detachable 4.0 Ah battery. A fixed outdoor dock is not in the included description.
How many UK reviews are in the saved listing?
The listing line is 4.0 from 32. The saved listing contains two UK review texts.
The WORX Landroid Vision Cloud WR305E is £799 for 500 m² in the title, with V-SLAM plus cloud RTK, no boundary cable and no local antenna claimed. Across 14 reviews the line is 4.0, so the score is 80, and twelve UK review texts are in the saved listing. Buyers who replaced a wired mower liked the lack of a cable and the cut once they had read the instructions. Others say it gets stuck on routes and did not cope with lots of narrow grass paths. Cutting height is not printed; the row only says five positions. Reviews assume a normal Landroid dock, which the bullets do not itemise. Battery average life is 2 hours, weight is 11.1 kg, and the warranty text is 2 year manufacturer. One review added an edge module separately, so close-edge cutting is a claim rather than a guaranteed finish.
Pros
Cons
Best for: You have about 500 m², open enough for cloud RTK, and you accept a small review sample.
Less suitable: Your lawn is a chain of narrow paths, or you want a large amazon.co.uk review count before you buy.
Specifications
Common questions
What area does the title state?
500 m², without a boundary cable.
How does it navigate?
The bullets say cloud RTK without a local antenna or boundary wire, vision mapping, and V-SLAM in shade.
How large is the review sample?
4.0 from 14 on the listing line. Twelve UK review texts are in the saved listing.
The SUNTEK SRM2025 is £399.99, stated up to 250 m², with AI vision and no boundary wires or RTK in the bullet, and it returns to a base station. The cut is 20 cm and a 20 V 2.5 Ah line appears in the slope bullet. Across 91 reviews the line is 3.9, so the score is 78. The title says up to 35° and a bullet says up to 35%, which are not the same figure, so the slope stays unclear. IPX5 and a rain sensor are printed, and the cutting-height field is a 6 cm maximum, not a range. Some buyers found the first setup easy. One called battery life about ten minutes, the app is described as limited, and a virtual boundary did not match what prompted one order. Eight UK review texts sit against that listing count of 91.
Pros
Cons
Best for: You want a docked vision mower around the stated 250 m² and you will quote both slope figures rather than pick one.
Less suitable: You need a single slope unit, a long proven runtime, or a fuller app than the reviews describe.
Specifications
Common questions
Wire or RTK?
The bullet says it operates without boundary wires or RTK, using visual AI, and returns to a base station.
What slope figure should you trust?
Do not pick one. The title says 35°. A bullet says 35%. Quote both or treat the slope as unclear.
What area and waterproofing are stated?
Up to 250 m². IPX5, with a rain sensor.
The WORX Landroid Vision Cloud WR306E is £899 for 600 m² in the title, with V-SLAM plus cloud RTK, no local antenna and no boundary wire. The bullets include a cut-to-zero module for less uncut grass along borders, and assembly required is No. Across 12 reviews the line is 3.9, so the score is 78. Reviews praise auto-map across more than one lawn and straight lines once Wi-Fi cooperated. They also say it gets stuck and often frees itself, that multi-area paths are hard in the app, and that the base needs a suitable power spot which is not itemised in the bullets. Weight is 12.8 kg and battery average life is 2 hours. Cutting height and slope are not printed, and there is no dedicated warranty row for this ASIN. Twelve reviews is a thin sample next to the eufy line in this comparison.
Pros
Cons
Best for: You want the 600 m² WORX with the cut-to-zero module and you can site a base on a suitable socket.
Less suitable: You need a large review sample, a printed cut height, or a simple single lawn that does not justify this price.
Specifications
Common questions
What is the cut-to-zero module?
The listing includes it and says it is for edge-to-edge mowing with less uncut grass along borders.
What area is stated?
600 m² in the title.
Boundary wire?
The title says without boundary cable. The bullets say no local antenna and no boundary wire.
The ECOVACS GOAT O800 RTK is £651.83 for 800 m², with lidar-enhanced RTK plus vision and no perimeter cable in the navigation claim. The listing states a 220 mm cut, a 3–8 cm height, paths of 0.7 m and slopes up to 45% in the title and a bullet. Across 33 reviews the line is 3.6, so the score is 72, the lowest star line in this set. Several owners call setup straightforward and like a tidy or diagonal pattern, and one says the battery covered a 200 m² zone per charge. A UK review says the mower arrived with no UK plug or adapter, assembly required is Yes, and another note says the charging lead was not included. One owner reported no UK repair network, and the mower veered into a hedge and a bed. A reviewer with about 189 m² wrote that a smaller model would have done the job. Weight is 21 kg.
Pros
Cons
Best for: You have a large awkward lawn near the stated 800 m² and you will check the plug and lead before the first charge.
Less suitable: You have a small lawn, or you need a UK plug confirmed in the specification rows and a stronger review line.
Specifications
Common questions
What navigation and area are stated?
Wire-free lidar-enhanced RTK plus vision, 800 m², paths of 0.7 m, slopes up to 45%, cut 220 mm, height 3–8 cm.
Does the listing say a UK plug is included?
It does not. Assembly required is Yes. A UK review says the mower arrived with no UK plug or adapter.
Is 800 m² the right size for a much smaller lawn?
One reviewer with about 189 m² wrote that a smaller model would have done the job. The listing itself is rated to 800 m².
Eleven amazon.co.uk listings were scored on 22 October 2026. The number on each row is the star rating times 20, so 4.6 becomes 92 and 3.6 becomes 72. Review count, a missing area, a thin UK text sample and a listing clash change the written assessment. They do not change the stored score. A carton that lists boundary wire was left out. This is not a laboratory cut.
Amazon.co.uk stars
100%The stored score is the amazon.co.uk star rating times 20. A 4.6 becomes 92. A 3.6 becomes 72. If the Customer Reviews line were missing, this part would not be invented. The score is not a cut trial.
Order the decision as area, then navigation, then dock or carry-out, then the slope unit, then what is actually in the carton. A printed maximum is for a favourable lawn. A star line is the amazon.co.uk listing, not a laboratory cut. Nothing below claims a safest model or a lift sensor we tested.
A robot lawnmower without boundary wire stays on the lawn using cameras, satellite positioning, lidar, or a mix, instead of a perimeter cable pegged around the grass. No wire is not one technology. Drop-and-mow vision has no dock. You place it and it cuts until the battery is flat, often at random, which suits one small lawn you can watch. Mapped vision uses cameras and an app to store a virtual boundary, then docks itself. It needs light, a crisp edge, and a signal at the dock.
A long boundary cable in the carton is a wire mower, even when the search said wireless. Magnetic no-go strips are a different thing: they mark a bed or a pond, they do not peg the whole lawn. If the included list names metres of perimeter wire, leave that listing out of this category.
A printed maximum is for a favourable lawn, not a guarantee on a shape broken into paths, beds and a side strip. Leave spare capacity. Two WORX titles in this set print no square metres at all, or print a different area from the next model, so do not copy a figure from a neighbouring ASIN.
Degrees and percent are not interchangeable, and one listing prints both 35° and 35%. Quote the clash or leave the slope blank. Do not average it. A tilt sensor in a safety bullet is not a climbing rating. Starting on long wet grass, or expecting a stripe from a random path, is a separate mistake.
Start with the maker's stated maximum and your own garden, not with the price. Leave spare capacity when paths, beds and a side strip break the shape. A printed maximum is for a favourable lawn, not a guarantee. If the title says only small to medium, or prints no square metres, do not borrow a figure from another model in the same brand. Narrow paths need the width the maker prints.
Camera vision wants a crisp edge and decent light. RTK wants open sky and is weaker under trees and beside tall walls. A hybrid or lidar is for those gaps. Drop-and-mow has no dock: you place it and it stops when the pack is flat. Mapped vision docks itself and needs a signal at the station. A dock needs an outdoor socket on a 30 mA RCD, and a new socket is an electrician's job. A removable battery charges indoors and will not mow while you are out.
Three typical situations, each with a recommendation from this comparison.
You can start a carry-out mower while you are at home, and you will strim the edges. The Bosch VISIMOW18V-100 kit includes an 18 V 4.0 Ah battery and charger, states up to 100 m², and has no dock. It will not mow while you are out.
You want the mower to dock and run when the lawn is inside the stated area, and you already have an outdoor socket or you will have one fitted. The eufy E15 is mapped pure vision with a cap under 800 m². Reviews treat dock siting, and Wi-Fi or 4G, as the practical limit.
You are choosing cloud RTK or a hybrid, and a 100 m² random mower is the wrong class even though it is also wireless. The WORX WR305E states 500 m², with V-SLAM plus cloud RTK and no local antenna claimed. The sample is 14 reviews, and narrow grass paths are where buyers say it gets stuck.
The stored score on each row is the amazon.co.uk star rating times 20, not a laboratory cut. The eufy E15 is the top pick: 4.6 from 580 reviews, pure vision, and a mapping cap under 800 m², at about £1499. The Bosch VISIMOW18V-100 kit is the best value at about £319 because the 18 V battery and charger are in the box. The body-only listing is not a complete machine. Match the printed area, and do not treat a missing slope, or a degree-versus-percent clash, as a settled climbing figure.
