The best pool robots, compared.
Top pick: EVERCROSS BOT U8-UK3 – Score 94 at about £339.99, with 4.7 from 14 reviews, and a wall claim that also states the rectangular limit. Round and oval pools stay excluded, and the UK note is one review. Best value: Bestway AquaTronix – About £151.20, with 4.4 from 268 reviews, for flat above-ground pools up to 18 m². A 30-minute run and a finish in the middle stay on the page. Updated October 2026.
A pool robot is a battery-powered machine that drives itself on the pool floor and collects debris in its own basket. Most people using these amazon.co.uk listings have a garden pool, often an above-ground liner. The decision is whether the listing's floor and shape sentence matches that pool. Stated runs are 30 to 180 minutes, and a printed charge is about 2.5 to 4.5 hours. Only one UK review is in the notes. The [pool robot buying guide](/hub/pool-care/pool-robot/sub/pool-robot-buying-guide) puts shape first, then runtime, lift and filter. Pole vacuums and surface skimmers were left out. Floor robots here are the Bestway AquaTronix, for flat above-ground pools up to 18 m² with a 30-minute run, and three rows, for flat pools up to 90 m² with 100 minutes stated. Wall-and-waterline claims are the two U8 rows, not for round or oval pools, up to 200 m², the C1 title, which says in-ground and 150 minutes, and the title, which says 180 minutes. The title says cordless and the power-source field says ac, so this page does not pick one power source. Pool size is not stated on the row. A different dp code on the same listing is not used.

Question 1 of 2
What should the robot clean?
The EVERCROSS BOT U8-UK3 is the top pick on these scores, at 94, listed at £339.99 with 4.7 from 14 reviews. The bullets claim floor, walls and waterline on rectangular or square pools up to 200 m², and they exclude round and oval pools. Dry weight is 10.5 kg, runtime is 120 minutes, and the basket is 6 litres with a 180-micron mesh claimed. Charge time and a retrieval method are not stated on this row. The listing notes have one UK review: a pool of about 8 m by 4 m, where it picked up leaves and dirt, climbed the walls, and let the owner leave it running, though that reviewer still checks the corners. Australian reviews on the same listing are not UK opinion. Wet weight is not stated, so the lift is at least 10.5 kg and more once the basket is full of water. A 4.7 on 14 reviews does not make a round pool eligible.
Pros
Cons
Best for: You have a rectangular or square pool, you can lift 10.5 kg dry, and you will still brush the corners.
Less suitable: A round or oval pool, or a buy you want supported by more than one UK review.
Specifications
Common questions
Can it clean a round pool?
The bullets say it is for rectangular or square pools up to 200 m² and is not compatible with round or oval designs.
Does the one UK review mention the walls?
Yes. The reviewer has a pool of about 8 m by 4 m, says it picks up leaves and dirt and climbs the walls, and still checks the corners.
How heavy is the lift?
The specification table says 10.5 kg. Wet weight is not stated.
The Bestway AquaTronix, model BW58864, is a 3.57 kg cordless floor robot for flat-bottom above-ground pools up to 18 m², priced at £151.20 with 4.4 from 268 reviews. It is the best value in this set: the next cheaper floor robot is £139 with 3.4 from 60, and this row has the largest review count in the cheap band. The bullets also say it is more efficient on rounds up to 4.88 m across and on rectangles or ovals up to 5.49 m long, and that a directional jet changes course at a wall or a larger obstacle. A stated run is 30 minutes, then a charge of 2.5–4.5 hours in the bullets or 4.5 hours in the table, so a second pass is later the same day. Fourteen UK reviews praise leaf clearance, including after a winter cover failed, and some say the battery lasts longer than 30 minutes. They also say it often finishes in the middle, that a hook was included and a pole was not, and that tipping the water back into the pool brings the dirt with it. One review describes a 10 ft by 26 ft oval steel-wall pool cleaned on one charge, which sits outside the 18 m² bullet, so that sentence is one owner's pool and not a new size limit.
Pros
Cons
Best for: You have a flat above-ground pool inside 18 m², you can fish the robot out, and you do not need the walls cleaned.
Less suitable: A pool longer than 5.49 m, a slope, or a waterline you want cleaned in the same cycle.
Specifications
Common questions
How big an above-ground pool is stated?
Flat-bottom above-ground pools up to 18 m². The bullets also say it is more efficient on rounds up to 4.88 m across and on rectangles or ovals up to 5.49 m long.
Does it clean the walls?
The bullets say it cleans the bottom. Wall climbing is not claimed.
How do you get it out?
UK reviews say it often finishes in the middle. One review says a hook was included and a pole was not, and that tipping the water back into the pool brings the dirt with it.
The AIPER Scuba S1 (2025) row is listed as B0DP6JFJPV at £999, with 4.4 from 136 reviews and a dry weight of 7.7 kg. The title claims floor, wall and waterline cleaning, 180 minutes, 15,900 L/h, a replaceable 3 μm filter and a standard 180 micron filter. Pool size, pool shape, dimensions and charge time are not stated on this row. The battery line prints 14.52 Wh beside the 180-minute claim, and that figure is left as printed. Two UK reviews in the notes are positive, and neither states a fault: one says the extra filter caught more dust over about a month than an older robot, and one calls it excellent. A French review on the same listing is not UK opinion. The URL on the same listing page is a different dp code, so this row follows the product-details ASIN, the £999 price, and the 2-year warranty in the bullets. Assembly is not required. It ties the Bestway on score and is not the best value.
Pros
Cons
Best for: You want the 2025 title's filter and runtime claims, and you accept a £999 row whose pool size is not stated.
Less suitable: A round-pool rule you need in writing on the listing, a stated charge time, or a price near the £150 floor robots.
Specifications
Common questions
Which ASIN is this row?
The product-details line says B0DP6JFJPV. The URL on the same listing page uses a different dp code, so this row follows the ASIN line and the £999 price.
What filter does the title claim?
A replaceable 3 μm filter and a standard 180 micron filter, plus 15,900 L/h. Basket volume is not stated.
What do the UK reviews in the notes say?
Two UK reviews are present. Both are positive: one mentions the extra filter catching more dust over about a month, and one calls it excellent. A fault is not stated in those two reviews.
The WYBOT C1, model OS70-C1 Green, is £649 on amazon.co.uk with 3.9 from 679 reviews, the largest count in this set. The title says a cordless wall-climbing robot, 150 minutes, for in-ground pools up to 65 ft, with larger top-loading filters. The power-source field says ac, and the item-type field on the same row says Above Ground Pool, so those lines conflict with the title and this comparison does not pick one. Dry weight is 10.4 kg and charge time is 3 hours. Twelve UK reviews say the floor is done well once it is set up, and that walls and floor can save a manual sweep, including most of an irregular kidney shape except a small patch. The same sample says the hook is not easy, wide steps are not cleaned, and fine particles go out the back because there is no micro filter. Units in those reviews stopped after about a year or would not charge, with support declined because the purchase was on Amazon. Load capacity is listed as 5 kg, and basket volume is not stated.
Pros
Cons
Best for: You have read both the cordless title and the ac line, and your in-ground pool has no wide steps you need the robot to clean.
Less suitable: A wide step, a kidney corner you cannot brush yourself, or a buyer who needs the power source to be a single sentence.
Specifications
Common questions
Is it cordless or mains?
The title says cordless. The power-source field says ac. A 99 Wh lithium battery and a 3 hour charge are also listed. This page does not pick one power source.
Does it clean steps?
A UK review says it cannot clean the wide steps. Another says a kidney-shaped pool still has a small missed patch.
What happens if it stops after a year?
UK reviews include a unit that stopped after about a year and a unit that would not charge, with support declined because the purchase was on Amazon. Warranty type on the row is Limited.
The EVERCROSS BOT U8-2026 is a different ASIN from the U8-UK3: £399.99, 3.9 from 58 reviews, 12 kg dry, 120 minutes, and a stated charge of 4.5 hours. It claims floor, walls and waterline on rectangular and square pools up to 200 m², on vinyl, tile and PVC, and it excludes round and oval pools. The bullets add a 6 litre top-loading basket, auto-edge docking and a retrieval hook. Nine UK reviews include a hopper-style pool where it coped with slopes and the walls, and a basket that is simple to empty. Other UK reviews say it is too quick, floats off a downslope by about 5 feet, repeats the same lane, and cleaned only three walls before the owner dragged it out after about an hour and a half. Bluetooth was missing for one buyer, and the supplier did not reply. One review calls a one-year guarantee stingy. The specification table does not state a warranty.
Pros
Cons
Best for: You have a rectangular pool, you want a stated hook, and you can lift 12 kg, knowing some UK reviews lose the slope.
Less suitable: A round kit pool, or a steep hopper you cannot afford to have the robot float off.
Specifications
Common questions
Is this the same unit as the U8-UK3?
No. This ASIN is U8-2026 at £399.99 and 12 kg. The U8-UK3 row is a different ASIN at 10.5 kg.
Which pool shapes are excluded?
The bullets say rectangular and square pools up to 200 m², and that it is not suitable for round or oval pools.
What do UK reviews say about slopes?
One review says a hopper pool and the walls were fine. Another says it is too quick, floats off a downslope, and repeats the same lane.
The POOLPURE RPC-100A is the white floor robot at £149, 3.4 from 100 reviews, listed at 3.8 kg with a 100-minute run and a push-button start. The bullets limit it to flat pools up to 90 m² and say it is not for slopes or heavy wrinkles. Eight UK reviews describe it as a time saver on the floor when a separate skimmer does the surface, and one says the battery life is fantastic and that it comes to the edge so it is easier to grab. The same reviews say it can be too fast and throw debris back into the water, and that the on/off button sometimes needs many firm presses before it starts. A wheel snapped off after about a week in one review, and another unit ran for about 20 seconds and then switched off. Load capacity is listed as 2 kg. Filter orientation was not obvious on first assembly for one buyer, and customer service did not reply, so that buyer returned it.
Pros
Cons
Best for: You have a flat pool inside 90 m², you will empty it after each run, and you will return it if the wheel or the button fails.
Less suitable: Fine silt you cannot afford to have thrown back, or a floor with a slope.
Specifications
Common questions
Will it climb the walls?
Walls are not claimed. The bullets limit it to flat-bottom pools and say it is not for sloped floors or heavy wrinkles.
Does it need tools to assemble?
The listing says assembly is not required. One UK review says the filter orientation and how the body fits are not obvious.
Why do some UK reviews say it misses dirt?
UK reviews say it can be too fast and throw debris up, and that the button sometimes needs many presses before it starts.
The POOLPURE AquaGuard SE II, part RPC100A, is a 3.8 kg cordless floor robot listed for flat above-ground and in-ground pools up to 90 m², with a stated run of 100 minutes. On amazon.co.uk it is £139 and 3.4 from 60 reviews. The bullets say it is not for sloped floors or heavy wrinkles, and they claim a park near the wall at 5% battery plus a U-shaped floating handle. Four UK reviews in the notes include a 16 ft by 8 ft above-ground pool that it cleaned, and a unit described as brilliant across about three uses. The same small sample also says a wheel broke off on first use, that it worked twice and then would not charge, and that after two days it ran for about half a minute and stopped with the battery still full. Charge time is 2.5–3 hours in the bullets and 3 hours in the specification table. IPX8 is a claim on the robot, not a stated test of the charger, and basket volume is not stated. It is cheaper than the Bestway and scores lower because those early failures are in the UK notes.
Pros
Cons
Best for: You have a flat pool inside the 90 m² sentence and you can return the unit if a wheel or the charger fails in the first days.
Less suitable: A slope, a heavily wrinkled liner, or a waterline you want the robot to climb.
Specifications
Common questions
Does this robot clean slopes?
The bullets say it is engineered for flat-bottom pools and is not suitable for sloped floors or heavy wrinkles.
How long is a charge and a run?
The title states 100 minutes. The bullets say a recharge of 2.5–3 hours, and the specification table says 3 hours.
What do UK reviews say about the wheels?
One UK review says a wheel broke off on first use, the unit worked twice, and then it would not charge.
The green POOLPURE RPC100A is a separate ASIN at £149, 2.8 from 13 reviews, with the same class of claim: a cordless floor robot, 100 minutes, flat pools up to 90 m², and 3.8 kg. Two UK reviews are in the notes. One describes a 24 ft by 12 ft above-ground pool that needed two runs and calls the result a great job. The other says cleaning is very good and that the battery could last longer, and that there is no cleaning pattern. The product-dimensions line says 32.4 x 32.1 x 17.1 cm, while a second line lists 33.8 x 33.2 x 19.1 cm, so the size on the page is not one figure. Voltage and watt-hours are not stated on this row, and assembly is not stated. Italian and German reviews on the same listing are not treated as UK opinion. A repeated defect is not stated, because only two UK texts are present.
Pros
Cons
Best for: You want this green floor robot and you have already matched a flat pool inside 90 m², knowing the UK sample is two reviews.
Less suitable: A buy that needs a large UK review sample, or one size figure you can trust before it arrives.
Specifications
Common questions
Is this a different robot from the white RPC-100A?
It is a separate ASIN. The part number is RPC100A, the title says green, and the price on this row is £149.
What pool size do the two UK reviews mention?
One UK review describes a 24 ft by 12 ft above-ground pool that needed two runs. The other says cleaning is very good and the battery could last longer.
Which size figure should you use?
The product-dimensions line says 32.4 x 32.1 x 17.1 cm and 3.8 kg. A second line lists display dimensions of 33.8 x 33.2 x 19.1 cm.
Eight amazon.co.uk listings were scored on 19 October 2026 from the listing fields, the UK review notes on those pages, and the public UK limits cited below. This was not a laboratory clean. Area, runtime, IP ratings and filter microns are listing claims. Reviews from outside the United Kingdom are not scored as British opinion. A missing figure stays blank. The four weights below sum to 100.
Amazon evidence
30%Star rating and review count on amazon.co.uk. A small count is a weak base. A star line with almost no UK text cannot carry this block on its own.
Listing fit
35%A floor and shape sentence you can match to a real pool scores. A wall claim scores when the shape limit is stated in the same bullets. A retrieval handle or hook scores. Conflicting power-source, watt-hour, size or ASIN lines lose points.
Review outcome
20%UK reviews that describe a finished clean on a pool the listing allows score. Early wheel, charge and cut-out notes, dirt thrown back, and a robot that stops in the middle are deducted. One UK review keeps this block modest.
Value
15%Shelf price in GBP against a listing whose floor sentence is still usable. The lowest price does not win this block when the UK notes are mostly early failures.
A pool robot in this comparison is a cordless machine that drives the floor and keeps debris in its own basket. On these eight amazon.co.uk listings the shelf runs from £139 to £999. Match the floor and shape sentence before runtime or filter mesh. A wall claim does not override a round-pool exclusion. Read [when a floor robot is enough](/hub/pool-care/pool-robot/sub/pool-robot-floor-or-walls) before you pay for a waterline claim.
A pool robot in this category is a battery-powered machine that drives itself on the pool floor and collects debris in its own basket. UK buyers on amazon.co.uk are mostly choosing one for a garden pool, often an above-ground liner. What you can check on the page is a stated area and shape, a runtime you can finish in, a way to get the robot out without swimming, and reviews that mention wheels, charging, and dirt thrown back into the water. Every robot kept in this set is cordless.
Both EVERCROSS rows say they are not for round or oval pools, in the same bullets as the 200 m² claim. A wall-climbing title does not override that sentence. The Bestway is the row that names rounds, and only up to 4.88 m on a flat above-ground floor.
POOLPURE bullets exclude slopes and heavy wrinkles even when they state 90 m². A stated run of 30, 100, 120, 150 or 180 minutes is not a second pass. Printed charges run to about 4.5 hours, and two rows do not state a charge time at all.
UK reviews of the Bestway say it often finishes in the middle, and that tipping the basket water back into the pool brings the dirt with it. These listings do not say it is safe to swim beside the robot. Charge on dry land, on a 30 mA RCD.
Flat-only bullets exclude slopes and heavy wrinkles. Two EVERCROSS rows exclude round and oval pools. A wall-climbing title does not override that sentence. Floor only in this set is the Bestway AquaTronix, up to 18 m², and the three POOLPURE rows, up to 90 m². Floor, walls and waterline are claimed by the EVERCROSS rows, the WYBOT title and the AIPER title. The WYBOT item-type field says Above Ground Pool while the title says in-ground up to 65 ft, so those lines stay in conflict.
Stated runs are 30, 100, 120, 150 and 180 minutes. Charges, where printed, run from about 2.5 hours to 4.5 hours, so a second pass is later, not immediate. Dry weight runs from 3.57 kg to 12 kg. Wet weight is not stated, so the lift is at least the dry figure and more with a full basket. The Bestway basket is 1.5 litres. The EVERCROSS baskets are 6 litres. The AIPER title states 3 μm and 180 micron filters. That is a claim, not a lab result.
Three typical situations, each with a recommendation from this comparison.
You can lift about 4 kg and the pool is a flat above-ground liner inside 18 m². The Bestway AquaTronix at about £151.20 cleans the floor only, with 4.4 from 268 reviews, a 30-minute run and a 3.57 kg dry weight. It does not claim the walls.
You want floor, walls and waterline, the pool is rectangular or square, and you can lift 10.5 kg dry. The EVERCROSS BOT U8-UK3 at about £339.99 states that job up to 200 m² and excludes round and oval pools. Only one UK review is in the notes, and charge time is not stated.
The pool is flat, inside 90 m², and you do not need the walls. The POOLPURE RPC-100A at about £149 states 100 minutes at 3.8 kg, with 3.4 from 100 reviews. UK notes include dirt thrown up and a wheel off after about a week, so the return window matters.
The top pick is the EVERCROSS BOT U8-UK3 at about £339.99. It scores 94, with 4.7 from 14 reviews, and the bullets claim floor, walls and waterline on rectangular or square pools up to 200 m². Round and oval pools are excluded in those same bullets. Only one UK review is in the notes, and charge time is not stated. The best value is the Bestway AquaTronix at about £151.20, with 4.4 from 268 reviews, because that price buys the largest review sample on a floor sentence a small flat above-ground pool can match. The £139 POOLPURE is cheaper and scores lower because the UK notes include a wheel off and a failed charge. The £999 AIPER row ties the Bestway on score and is not the value row.
