The best robot lawn mowers, compared.
Top pick: eufy E15 – 4.6 from 580 reviews gives the highest listing score here, 83, at about £1,499, with the listing's own limits on area, bumps and slope. Best value: Bosch VisiMow 100 set – 4.5 from 58 reviews at about £319, with the 18 V pack and charger in the box. The bare tool is cheaper and does not include them. Updated 23.10.2026.
A robot lawn mower is a battery rotary that keeps a domestic lawn at a set height by cutting little and often. In the United Kingdom you buy one to save time on a lawn you already mow regularly. Some models return to a dock. On some small models you carry the mower indoors to charge. You tell a suitable robot lawn mower apart from checks that still apply when the models change. Measure the lawn, including narrow links, and compare it with the stated working area. Treat that figure as the maker's rating for a lawn already maintained, not as one charge. Read the slope in the unit the listing uses. Percent is rise over run: 40 percent is about 22 degrees, not 40 degrees. A perimeter wire is predictable under trees. Cameras, a corrected satellite fix or a laser scan drop the cable and fail in different ways. A dock needs an outdoor supply and a BS 1363 plug. Edges against walls still need a strimmer. The [robot lawn mower buying guide](/hub/lawn-and-garden-equipment/robot-lawn-mower/sub/robot-lawn-mower-buying-guide) sets those questions in order.

Question 1 of 2
Will you lay a perimeter wire?
eufy E15 is about £1,499 with 4.6 from 580 amazon.co.uk reviews, the largest sample in this comparison. The listing tells you to check the lawn first: under 800 m², bumps under 3 cm, slopes under 40 percent (18°), and not St. Augustine or dense Zoysia. Navigation is pure vision with Wi-Fi or 4G, and no wire or RTK station. Height is 1–3 cm. Battery life is listed as 60 minutes. Cutting width and the boxed contents are not stated. A 4G plan is extra if Wi-Fi does not cover the garden. Reviewers praise the lack of a wire and the mapping, and several call the price high. It leads this comparison on review depth. It is the wrong mower if the lawn fails the listing’s own slope and flatness test.
Pros
Cons
Best for: A mostly flat lawn inside 800 m² where the price is acceptable and you want the largest UK review sample in this comparison.
Less suitable: A bumpy or steep garden, St. Augustine or dense Zoysia, or a budget under the mid hundreds.

Navigation on this listing is Pure vision, Wi-Fi or 4G, no RTK station. Boundary wire: No boundary wire. That is the listing’s description, not a measured edge distance.
What area, cut, and height are listed?
Stated area: Under 800 m² mapped. Cutting width: not stated. Height: 1–3 cm, 3 positions. Slope: Less than 40% (18°) stated as a limit.
What arrives in the box, and what is the amazon.co.uk price?
Included: not stated. Battery line: Life listed 60 minutes; separate pack not stated. Price on this snapshot: about £1,499.
The Bosch VisiMow 100 set is about £319 on this amazon.co.uk listing, with 4.5 from 58 reviews. The title states lawns up to 100 m², a 16 cm cut and a height of 20–60 mm, and the box includes an 18V 4.0Ah battery and charger. Bullets describe a wire-free Smartvision mower with a three-button start and no boundary infrastructure. In the first 43 UK review bodies, quiet running and carrying it between lawns come up often. The same reviews say the edges still need a trim, the route is not a pattern, and steep edges or yellow grass can stop a clean pass. It suits a small lawn and an indoor charge. It is a poor fit if you need a dock, a stripe, or a bank the listing does not rate.
Pros
Cons
Best for: A small lawn around the stated 100 m² where you already like Bosch 18V packs and can carry the mower indoors to charge.
Less suitable: A large or steep garden, or anyone who wants stripes and a finished edge without a strimmer.

WORX WR304E is about £661.62 with 4.5 from eight reviews, all eight in the UK text. The highlight says up to 400 m² with VSLAM and RTK cloud and no boundary wire. Weight, footprint, and a two-hour battery-life line match the other Vision Cloud listings. Height range, cutting width, and slope are not stated. Reviewers like skipping the wire. One says it needs strong outdoor Wi-Fi. Another says the cut, the docking, and the obstacle behaviour were poor on a small uneven lawn and that the machine suits a large flat lawn instead. Eight reviews cannot carry a 4.5 as if it were a large-sample result. Read it as a 400 m² wire-free option with a thin evidence base.
Pros
Cons
Best for: A flat lawn near the stated 400 m² with solid outdoor Wi-Fi, if you accept eight reviews as the whole written sample.
Less suitable: A small, patchy, uneven garden. One of the eight reviews says the cut and the docking suffer there.

Gardena SILENO minimo 250 is about £374.99 with 4.4 from 22 reviews. The style line is the UK plug. The box list is the mower, a charging station, 150 m of boundary wire, 150 hooks, connectors, and terminals. Bluetooth range is stated up to 10 m. Height is listed as 2.5 cm minimum and 1.97 inches maximum across 81 positions, which mixes units. Noise of 57 dB(A) and “quietest in its class” are the maker’s words. Bullets say it mows in the rain. In 16 UK reviews the wire is the sore point: inflexible, and said to rot when wet. The cut is praised once a daily schedule is running. Gardena’s own UK support page rates this minimo family at 25 percent slope; that number is not in this amazon technical block, so the table says not stated. Buy it for a simple lawn and a UK plug. Do not buy it if you refuse to own a wire.
Pros
Cons
Best for: A simple lawn near 250 m² where you will peg 150 m of wire once and you want a stated UK plug on the station.
Less suitable: Anyone who will not maintain a perimeter wire, or who needs a slope figure from this listing. It does not print one.

This is the same VisiMow 100 story without the battery or charger, at about £296, with 4.1 from 72 reviews and 14 UK review bodies in the file. Included components are the mower only. Weight is 8.15 kg against 9.77 kg on the set listing, and the origin line says China rather than Hungary. Title figures match the set: 100 m², 16 cm, 20–60 mm, wire-free. Reviewers who already own 18V packs use it because they could not fit an outside socket. Others report a stuck battery latch and a 5-inch edge left to strim. Buy it only if the pack is already on the shelf. Otherwise the set listing is the one that runs on day one.
Pros
Cons
Best for: Someone who already owns a Bosch 18V 4Ah-class pack and charger and has a straightforward lawn near 100 m².
Less suitable: A first robot with no Bosch battery at home. The £23 gap to the set does not include a pack.

MOVA ViAX 300 is about £408.45 with 4.1 from 58 amazon.co.uk reviews. Bullets claim a recommended 300 m², wire-free mapping, no RTK station, slopes up to 40 percent, and a MOVAhome app. The technical block lists a 2–6 cm height and 19.3 kg. Cutting width and whether a battery is boxed separately are not stated. In the first 40 UK reviews, easy set-up and no wire are the praise, and edges plus a mid-mow recharge are the complaints. GPS tracking is an optional module in the bullets, not a proven tracker in this comparison. It fits a wire-free mid lawn. It is the wrong pick if you need a light carry or a finished edge.
Pros
Cons
Best for: A garden near the stated 300 m² where you want wire-free mapping and can accept a heavy 19.3 kg machine and a strim along walls.
Less suitable: Anyone who needs a one-charge cut of the full rated area, or a flush cut against vertical edges.

WORX WR303E is about £671.99 with 4.1 from 38 reviews. The highlight says lawns up to 300 m², an 18 cm cut, VSLAM plus RTK cloud, and no boundary wire. Warranty is two years. Height range and the battery pack in the box are not stated; average battery life is listed as 2 hours. Slope is not stated on this listing. Among 28 UK reviews, no-wire set-up is the praise. One reviewer could not get it through the path between house and garage, and WORX told them nothing could be done. A magazine hands-on exists elsewhere; it is not a measurement in this comparison. Choose it for an open 300 m² lawn. Skip it if the lawns only connect through a tight gap.
Pros
Cons
Best for: An open lawn up to the stated 300 m² where you want RTK cloud plus a camera and you do not have a narrow gap between buildings.
Less suitable: A garden whose lawns join through a tight alley. One UK review says this model cannot learn that path.

YARDCARE V3 is about £369.99 with 4.0 from 131 amazon.co.uk ratings. Only 15 UK review bodies are in the review text, so the written themes are that subset. Bullets claim vision navigation, no boundary wire, about 50 dB, a rain sensor, magnetic no-go strips, and a height of 20–60 mm. A 35° tilt sensor is a safety line, not a stated working slope. Area, cutting width, and battery-in-box are not stated. Praise in the 15 reviews is a useful small-lawn cut. One buyer returned it for crossing borders and clogging in long grass. The 50 dB line is the maker’s claim, not a measurement here. It is a budget no-wire option when you will keep the grass short. It is a poor fit beside open beds.
Pros
Cons
Best for: A small garden if you want a no-wire mower at about £370 and you will still strim and keep the grass short.
Less suitable: A lawn with open flower borders or long grass. One reviewer returned it for leaving the lawn.

YARDCARE V100 is about £349.99 with 4.0 from 32 ratings, but the review text contains only two UK review bodies. A German review further down is not used. Bullets state vision navigation, no boundary cable, up to 150 m², a 16 cm cut, five heights from 20–60 mm, slopes up to 20°, a detachable 18V 4Ah battery, and two 5 m magnetic wires. Both UK reviews describe an easy button start and a cut they were happy with, one of them in random directions. That is a short evidence base. It can be the small-lawn pick if the spec list matches and you accept the thin written reviews. It is a weak pick if you want hundreds of UK comments before you buy.
Pros
Cons
Best for: A small lawn near the stated 150 m² if you want a detachable 4Ah pack and magnetic no-go strips and you can live with almost no UK review text in this comparison.
Less suitable: Anyone who needs a deep UK review sample before paying. Thirty-two stars are not the same as thirty-two written UK reviews here.

WORX WR305E is about £799 with 4.0 from 14 reviews, 12 of them in the UK review text. The title says 500 m² and no boundary cable. Bullets match the Vision Cloud claim: RTK from the cloud, VSLAM in shade, app zones. Weight 11.1 kg, five height positions, battery life listed as 2 hours. Cutting width, height range, and slope are not stated. Reviewers who escaped a breaking boundary wire are pleased, including one who mapped paths by hand. Others say it is muddled if the garden is not flat. The area step up from the WR303E is real on the title and thinly reviewed. Use it for a large, even lawn. Do not use it to fix a rough one.
Pros
Cons
Best for: A larger lawn near the stated 500 m² if you will map no-go zones yourself and the ground is reasonably even.
Less suitable: A bumpy garden. Reviewers say it gets muddled when the lawn is not flat and neat.

SUNTEK’s vision mower is about £399.99 with 3.9 from 91 ratings and eight UK review bodies in the file. Bullets claim up to 250 m², a 20 cm cut, height 3–6 cm, no wire and no RTK base, a 20V 2.5Ah system, IPX5, and a rain sensor. The title says slopes up to 35° and a bullet says 35 percent. Those are different gradients, so this comparison will not pick one. Reviewers say the battery will not do 250 m² in one charge and that virtual boundaries were not editable in the app. Support was hard to reach for that buyer. Weight is 17.7 kg. It is a low-to-mid price vision mower only if the lawn is smaller than the badge and you can live with the slope clash.
Pros
Cons
Best for: A lawn well under 250 m² if you accept a vision mower at about £400 and you do not need to redraw boundaries in the app.
Less suitable: Anyone who needs reliable app editing or a single charge of the full stated area. The slope line is inconsistent.

MOVA LiDAX Ultra 800 is about £649. The raw extract has no customer-review line and no UK review bodies, so the rating is not stated, not a silent zero from another marketplace. Bullets claim 360° 3D LiDAR, no wires and no RTK station, edges within 5 cm, slopes up to 45 percent, and app height from 3 to 10 cm. The technical block lists a 28 cm cut and 12 kg. The word 800 in the name is not treated as a lawn area, because no square-metre rating appears in the bullets. Spare-part availability is listed as 3 years. There is nothing here to say whether the edge claim survives contact with a real fence. Do not treat it as a proven pick. It is a spec sheet with a price.
Pros
Cons
Best for: Only if you specifically want the stated 28 cm cut and 3–10 cm app height and you accept a listing with no star rating in this comparison.

Nobody mowed these lawns for this page. Shelf prices, star lines, review counts and listing figures are the amazon.co.uk figures stored for this comparison. A square metre, a slope or a wire length is the figure that listing prints. Each 0–100 score is the star component plus a review-sample step plus a specification step plus a small value step. Stars are the amazon.co.uk rating divided by 5, then multiplied by 40. A listing with no review line scores 0 on stars and on sample. It is not a lab test.
Star rating
40%Stars are the amazon.co.uk rating divided by 5, then multiplied by 40, so a five-star line would contribute 40. A listing with no review line scores 0. The weight matches that cap.
Review sample
25%Sample steps up with the review count stored for that listing: a handful scores 4, the low teens to the mid-twenties score 8, the thirties score 12, roughly 50 to 100 reviews score 16, 131 reviews score 20, and 580 reviews score 25. A thin file does not match a deep one.
Listed specification
20%Spec is 10, 15 or 20 according to how much of area, cutting width, height, navigation and battery the listing actually states. A missing figure stays missing. It is not filled from another marketplace.
Value on the shelf price
15%Value is the small stored component, between 4 and 9 points inside the 0–100 score. It is not a measured cut per pound. The published weight is 15 so these four weights add to 100. The stored add on each row stays inside 4 to 9.
Match the lawn you already mow to a stated area, a navigation method and a slope figure, then check how it charges. A wire is a different purchase from a camera or a laser scan. A dock needs an outdoor socket and a UK plug. Prices below are this amazon.co.uk snapshot, not a live re-check, and none of the scores is a lab test.
A robot lawn mower is a battery-powered rotary that holds a domestic lawn at one height by taking a little off, often, rather than waiting for a weekend cut. In a UK garden that usually means a lawn you already keep short. The machine is a poor first pass through long, wet grass. Some models return to a charging dock. Some small models have no dock: you carry them out and charge the pack indoors. That suits a house with no outside socket if you already own that battery system.
The stated square metres are a maker's rating for a lawn that is already short. Reviews on these listings often describe a recharge before that area is finished. Measure the real lawn, including narrow links, and leave headroom.
40 percent is 40 cm of rise in every metre, about 22 degrees, not 40 degrees. A tilt-sensor angle is a safety cut-out. If the bank is steeper than the stated limit, keep a push mower for that strip.
Several UK reviews describe a random path rather than a stripe, and a strip left against walls and fences. Budget a strimmer. Do not bury a thin wire and then scarify over it, and do not assume every model tracks by GPS.
Working area comes first, and it needs headroom. The figure on the listing is the maker's rating for a lawn that is already maintained. It is not a promise that one charge will finish that area. Measure the grass you actually have, including narrow links between a front lawn and a back lawn. Reviews on these listings often describe a return to the charger before the rated area is done. If the title and the bullets disagree, do not pick a single number and ignore the other.
Read the slope in the unit that listing actually prints. Percent is rise over run: 40 percent is 40 cm up in every metre, about 22 degrees, not 40 degrees. A tilt sensor is a safety cut-out. It is not a climbing claim, even when the listing prints a degree figure next to the word tilt. If one listing puts degrees in the title and percent in a bullet, those are different gradients, and this page does not choose one of them. Where the listing states no slope at all, the table shows a dash.
Three typical situations, each with a recommendation from this comparison.
You mow a lawn around the stated 100 m² and you have no outdoor socket, so the mower has to come indoors to charge. The Bosch VisiMow 100 set is about £319, with 4.5 from 58 reviews, and the 18 V 4.0 Ah pack and charger are in the box. Edges still need a strimmer.
You want a dock and a route the listing itself calls mostly flat. The eufy E15 is the top pick here, at about £1,499 with 4.6 from 580 reviews. The listing limits it to under 800 m², bumps under 3 cm and slopes under 40 percent. Separated lawns may need a second base.
The shape is straightforward and you will lay a loop once. The Gardena SILENO minimo 250 is about £374.99 with 4.4 from 22 reviews. The box lists 150 m of boundary wire and a charging station with a UK plug. The wire is the complaint in the UK reviews, and this listing prints no slope.
The top pick is the eufy E15. It scores 83, the highest figure in this set, from 4.6 and 580 amazon.co.uk reviews, at about £1,499. The listing limits it to lawns under 800 m², bumps under 3 cm and slopes under 40 percent (18°). The best value is the Bosch VisiMow 100 set, at about £319 with 4.5 from 58 reviews, a 16 cm cut and an 18 V 4.0 Ah pack and charger in the box. The bare Bosch tool is cheaper at about £296 and is not the value pick, because the pack and charger are not in that box. Neither result is a lab ranking.
