The best robotic pool cleaners, compared.
Top pick: EVERCROSS BOT U8-UK3 Best value: Bestway AquaTronix G150 – About £95.93, with 4.2 from 60 reviews and a UK note of a 12 ft round bottom. Runtime is not stated on the listing. Updated October 2026.
A robotic pool cleaner is a self-propelled machine that collects debris in its own filter. On amazon.co.uk, the usual choice is a domestic above-ground pool or a smaller in-ground pool. Split the listings by floor-only against floor, walls and waterline, then by cordless against corded. A useful page states the pool shape, a micron figure and a weight you can lift. Floor robots, the hzexun and the do not claim walls. U8, the raw listing, the C1 title and the CC claim walls. Both listings say rectangular or square only, not round or oval, up to 200 m². The [robotic pool cleaner buying guide](/hub/pool-care/robotic-pool-cleaner/sub/robotic-pool-cleaner-buying-guide) is the question order, and it does not pick a winner. A star line on its own is not that specification. That range is a snapshot of these files, not a market survey. A solar surface skimmer was the wrong product type and is not in the set. AquaGuard SE II and say flat bottoms, not sloped floors or heavy wrinkles.

Question 1 of 2
Which surfaces do you need cleaned?
The EVERCROSS BOT U8-UK3 at about £339.99 claims the floor, vertical walls and the waterline on rectangular or square pools up to 200 m², and it says it is not for round or oval pools. The filter is a 6 litre basket with 180 micron mesh, the runtime claim is 120 minutes, and the app offers four modes. It weighs 10.5 kg, the body is 40 x 43 x 21.5 cm, and the battery is printed as 5,100 mAh. The amazon.co.uk line is 4.7 from 14 reviews. The one UK review in the file describes an 8 by 4 metre pool, with leaves and dirt picked up and walls climbed, and corners still checked by hand. Fourteen reviews are a thin sample next to that 4.7, and a retrieval method is not stated.
Pros
Cons
Best for: You have a rectangular or square pool and you want a stated 180 micron mesh with a wall claim.
Less suitable: A round or oval pool, or a decision you will rest on 14 reviews alone.
Specifications
Common questions
Will it clean a round pool?
No. The listing says rectangular or square pools up to 200 m², and that it is not compatible with round or oval designs.
What filter does this U8 listing state?
A 6 litre basket and a 180-micron mesh. Surfaces named are tile, mosaic, PVC and vinyl.
How many UK reviews are in the file?
One. It describes an 8 by 4 metre pool, leaves and dirt picked up, walls climbed, and corners still checked. The listing average is 4.7 from 14 reviews.
The Aiper Scuba S1 (2025)-DE raw listing is about £999, and it claims the floor, the wall and the waterline, with a replaceable 3 μm filter and a 180 micron filter. The runtime claim is 180 minutes, control is the Aiper app, the weight is 7.7 kg, and a two-year warranty line is printed. The battery field says 14.52 Wh, and a charge time is not stated, so that energy figure is not reconciled with the 180 minute claim. The amazon.co.uk URL is B0FCFDMQH6, while the product-details table in the same file prints ASIN B0DP6JFJPV. The average is 4.4 from 136 reviews. Two UK reviews in the file are short and positive, and one says the extra filter pulled more dust. A pool-size limit is not stated, and the model code on the file is the DE variant. A later look at the same URL showed a retitled listing at £549. This page uses the raw file’s £999.
Pros
Cons
Best for: You want both a fine filter and a coarser one stated on the page, and you will confirm the live ASIN is B0FCFDMQH6.
Less suitable: A budget under a few hundred pounds, or a buy you will make without checking the clashing ASIN in the details table.
Specifications
Common questions
What filters does the raw listing include?
A replaceable 3 μm ultra-fine filter and a 180 micron filter. The title also prints 15900 LPH and is cut off in the file.
Which ASIN is this?
The amazon.co.uk URL is B0FCFDMQH6. The product-details table in the same file prints ASIN B0DP6JFJPV. The model name in the file is Scuba S1(2025)-DE.
What is the UK review sample?
Two UK reviews, both short and positive. One says the extra filter pulled more dust. The listing average is 4.4 from 136 reviews.
The Dolphin Nautilus CC Plus at about £1,699 is the corded robot in this set: the bullets say plug in, drop in and power on, for in-ground pools up to 50 ft, with wall climbing and scrubbing and about two hours on the mains. It weighs 9.45 kg, the basket is top-loading, and the control is described as touch. The battery-description field still says lithium-ion, which is not a runtime on an AC listing. The amazon.co.uk line is 4.2 from 13,341 reviews, by far the largest sample here. UK reviews say it cleans when it is working, and they also say the cable falls short of a 50 ft pool once the run to the socket and the depth are taken off, and that the instructions say not to use an extension cable. Several UK reviews say a motor failed or the cable sheath split, and that the warranty was then described as invalid in the UK or valid only in the US.
Pros
Cons
Best for: You have an in-ground pool, a socket the cable can reach without an extension, and you want the largest review file.
Less suitable: A socket far from the water, a round above-ground pool, or a repair path you need confirmed in the UK before you pay.
Specifications
Common questions
Is the Nautilus CC Plus cordless?
No. Power source is AC and the bullets say plug in, drop in, and power on. The battery-description field still says lithium-ion. That field is not a runtime.
Will the cable cover a 50 ft pool?
The title says in-ground pools up to 50 ft. A UK review says part of the cable is used to reach the power supply, the pool depth uses more, and the instructions say not to use an extension cable.
What do UK reviews say about the warranty?
Several UK reviews say a motor failed or the cable sheath split, and that the warranty was then described as invalid in the UK or valid only in the US. Other UK reviews say it cleans well.
The Bestway AquaTronix G150 is listed at about £95.93 and 2.41 kg, with a stated filter capacity of 2 litres. Runtime, coverage, pool size and power source are not stated on the listing. One UK review describes it working on the bottom of a 12 ft round pool for about 30 to 40 minutes. Another UK review says the run fell to about 20 minutes, and to less than that after a few uses. The amazon.co.uk average is 4.2 from 60 reviews, the strongest star line among the floor robots under £100 in this set. Included parts and a micron rating are not stated. This is the best value here if your job is a small flat bottom and you can accept a runtime the listing itself does not print.
Pros
Cons
Best for: You want a light robot for the bottom of a small round pool and you will time the first runs yourself.
Less suitable: A wall and waterline clean, or a pool where you need a printed runtime before you buy.
Specifications
Common questions
Does Bestway state a runtime?
No. Runtime is not stated on the listing. One UK review says 30 to 40 minutes on a 12 ft round pool. Another says about 20 minutes, and less after a few uses.
Does the listing say it climbs walls?
No. Coverage is not stated. UK reviews that describe a job talk about the pool bottom.
What is in the box?
Included components are not stated. Capacity is 2 litres and weight is 2.41 kg.
The WYBOT C1 is listed at about £649, and the title claims 150 minutes, wall climbing and in-ground pools up to 65 ft, with a top-loading filter. The battery field is 25.2 V and 99 Wh lithium-ion, the charge time is 3 hours, and the dry weight is 10.4 kg. The power-source field on the same page says ac, so the file does not settle whether this unit is cordless. The amazon.co.uk average is 3.9 from 679 reviews, the deepest cordless-titled count in this set. UK reviews praise the floor clean, and they also describe a missed patch on a kidney pool, wide steps left undone, a unit that stopped after about a year, and one that would not charge. One owner says Wybot would not support an Amazon purchase. A micron rating and a floor-slope limit are not stated, and a UK review calls hooking the robot out awkward.
Pros
Cons
Best for: You want the largest review file on a cordless-titled wall claim and you will read the power field before you pay about £649.
Less suitable: Wide steps, a kidney shape you need fully covered, or a warranty path you cannot confirm with the seller.
Specifications
Common questions
Is the Wybot C1 cordless?
The title says cordless and the battery field is 99 Wh lithium-ion at 25.2 V. The power-source field says ac. Both are in the raw file.
What pool length does the title claim?
In-ground pools up to 65 ft, with a 150 minute runtime and wall climbing. A micron rating is not stated.
What do UK reviews repeat?
Floor cleaning is praised. A kidney pool left a small missed patch. Wide steps were not cleaned. One unit stopped after about a year. One would not charge, and the owner says Wybot would not support an Amazon purchase.
The EVERCROSS BOT U8-2026 at about £399.99 claims the floor, the walls and the waterline on rectangular and square pools up to 200 m², and the listing says it is not for round or oval pools. You get a 6 litre basket, a stated 120 minutes, a 29.4 V 5,100 mAh pack, a 4.5 hour charge, an app with four modes, auto-edge docking and a retrieval hook. Dry weight is 12 kg. The amazon.co.uk score is 3.9 from 58 reviews, a larger file than the 4.7 on the U8-UK3. UK notes praise the filter and the wall climb for some owners, and they also say it completed only three walls, floated off a slope, or that customer service did not appear to cover the UK. A micron rating is not stated on this file. This is the top pick in the set because the wall claim, the basket and a mid-size review file sit together, though a round pool and a steep slope are outside that claim.
Pros
Cons
Best for: You have a rectangular or square pool and you want walls and the waterline from a cordless robot with a hook.
Less suitable: A round or oval pool, a steep slope, or a buy that depends on UK support the reviews already doubt.
Specifications
Common questions
Is this the same listing as U8-UK3?
No. This is model U8-2026 at about £399.99 and 12 kg. U8-UK3 is B0FS7HV992 at about £339.99 and 10.5 kg. Both claim 6 litres, 120 minutes and rectangular or square pools. This file does not state 180 micron.
Does it suit a round pool?
The listing says it is not suitable for round or oval pools.
What went wrong for UK buyers?
One says it only completed three walls. One says it is too fast on a slope and floats off the floor. One says customer service did not appear to cover the UK. Others praise the filter and wall climbing.
The POOLPURE RPC100A at about £88.63 is a cordless floor robot, and the bullets keep it on the floor of pools up to 900 sq ft. Flat bottoms and gentle slopes up to 8° are named; steps, steep slopes and heavily wrinkled liners are called out as things to avoid. The listing claims up to 100 minutes from an 11.1 V, 57.72 Wh pack, a 2.5 hour charge, IP68, and a floating handle with a retrieval hook. Dry weight is 3.63 kg. The amazon.co.uk line is 3.5 from 55 reviews. No UK review text is in the file, and the review text that is saved is marked United States, so the 3.5 is not a British verdict. A wall or waterline claim is not stated. An IP68 bullet is a listing claim, not proof the unit cannot leak.
Pros
Cons
Best for: You have a flat or gently sloped floor and you want a hook to lift a light robot out.
Less suitable: A wall or waterline job, or a buy you will make only on UK owner notes, because none are in this file.
Specifications
Common questions
Will it climb walls?
The bullets describe floor cleaning. A wall or waterline claim is not stated.
What slopes does the listing allow?
Flat bottoms and gentle slopes up to 8°. It says to avoid heavily wrinkled liners, large obstacles, steps and steep slopes.
Are there UK reviews in the file?
No. The star line is 3.5 from 55. The review text in the file is marked United States.
The POOLPURE RPC-100A at about £149 shares the flat-bottom limit, the 3.8 kg weight, the 34.2 x 32.1 x 17.1 cm body and the 100 minute claim with the AquaGuard SE II. This listing is the push-button version, with an 11.1 V pack printed as 55.5 Wh, a 3 hour charge, an IPX8 claim and a floating handle. The amazon.co.uk line is 3.4 from 100 reviews, a larger file than the SE II. Some UK reviews say a flat above-ground bottom comes up clean. Others say it drives too fast and throws fine debris back into the water, and that a wheel snapped or the button was unreliable. Saltwater is not stated, and the listing still excludes slopes and heavy wrinkles. The IPX8 line is a claim, not a leak test.
Pros
Cons
Best for: You want the larger 100-review file on a flat above-ground floor and you will watch the first cycle.
Less suitable: Fine silt you cannot have thrown back, or any floor the listing calls sloped or heavily wrinkled.
Specifications
Common questions
How is this different from the AquaGuard SE II listing?
This ASIN is model RPC-100A at about £149 with push-button control. AquaGuard SE II (B0G1Y8TZC2) is about £139 and lists part number RPC100A. Both state 3.8 kg, the same body size, a flat-bottom limit and a 100 minute claim.
Why do some UK reviews say it makes the pool worse?
More than one UK review says it moves too fast and throws fine debris back into the water. Others say it cleans a flat above-ground bottom well.
Is there a wall-climbing claim?
No. The listing limits it to flat-bottom pools and says it is not for sloped floors or heavy wrinkles.
The POOLPURE AquaGuard SE II at about £139 is a cordless floor robot for flat pools up to 90 m², with a stated run of 100 minutes and a charge of about 2.5 to 3 hours. It weighs 3.8 kg, the battery is given as 11.1 V and 56 Wh, and the listing claims IPX8 plus a floating handle that parks at 5% battery. Sloped floors and heavy wrinkles are excluded, and a wall claim is not stated. The amazon.co.uk score is 3.4 from 60 reviews. One UK review says a wheel came off on first use and the unit then would not charge. Another says it ran for two days and then cut out after about half a minute on a full battery. The IPX8 line is a claim, not a leak test.
Pros
Cons
Best for: You have a flat, firm floor and you want the £139 POOLPURE rather than the £149 push-button twin.
Less suitable: A wrinkled liner, a slope, or a first robot where an early wheel or charge failure would leave you without a clean.
Specifications
Common questions
Can it clean a sloped floor?
The listing says it is for flat-bottom pools and is not suitable for sloped floors or heavy wrinkles.
Does it claim the waterline?
No. Coverage in the bullets is the floor of flat above-ground or in-ground pools up to 90 m².
What failed in UK reviews?
One wheel came off on first use and the unit then would not charge. Another ran for two days and then stopped after about half a minute on a full battery.
The YDHZ cordless robot is listed at about £76.14, and the title claims 120 minutes on an above-ground or flat in-ground pool of up to 1,000 sq ft. You start it from a push button, and the bullets claim it parks itself. The same page prints dimensions of 25 x 25 x 25 mm and a 1 Wh AAA cell at 1 g, next to a weight of 3.63 kg. Those catalogue lines are not reconciled with the weight. The amazon.co.uk average is 3.3 from 9 reviews. The one UK review in the file says the cleaner is not worth £5, let alone the price paid. A wall or waterline claim is not stated, so this row does not cover a scum line.
Pros
Cons
Best for: You are checking the cheapest listing and you will read the size and battery lines before you buy.
Less suitable: A waterline you need cleaned, or a purchase made without noticing the conflicting catalogue figures.
Specifications
Common questions
Does the listing say it cleans walls?
No. The bullets describe an above-ground or flat in-ground pool and self-parking. A wall or waterline claim is not stated.
Do the size figures match the weight?
The listing prints 25 x 25 x 25 mm and a 1 g battery beside a weight of 3.63 kg. Both figures are on the page. They are not reconciled in the file.
What do UK reviews say?
The file has one UK review. It says the cleaner is not worth £5, let alone the price paid. The listing average is 3.3 from 9 reviews.
The hzexun floor robot at about £155 claims 100 minutes on the bottom of above-ground and in-ground pools up to 1,000 sq ft, with a 180 μm figure in the bullet and parking at the wall at 10% battery. The control field says remote, the dry weight is 4.73 kg, and the charge time is 3 hours. The bullet also says 5,000 mAh, while the energy field says 18,000 mAh, and the capacity field says 180 microlitres beside the 180 μm bullet. Both pairs are printed and neither is reconciled. The amazon.co.uk score is 3.1 from 13 reviews. UK notes say it can stick under an in-pool pump, and that one unit would not run the next season even though the light showed a charge. A wall claim is not stated.
Pros
Cons
Best for: You only need the bottom done and you will check which battery figure is on the live page.
Less suitable: A pool with a pump sitting in the water, or a robot you will store all winter and expect to start in spring.
Specifications
Common questions
Does it clean walls?
The bullet says it vacuums the bottom. A wall claim is not stated.
Which battery figure is on the listing?
The bullet says 5000 mAh and 100 minutes. The energy field says 18000 mAh. Both are printed. The file does not say which one to use.
What do UK owners report?
One says it picks up algae dust. Another says larger pieces are better than fine algae. It can stick under an in-pool pump. One unit would not run the next season even though the light showed a charge.
Eleven amazon.co.uk listings were scored on 19 October 2026 from the prices and star lines on those listings and the UK review notes kept with them. This was not a laboratory test. Runtime, area, micron and water-resistance figures are listing claims. A star line on a spec table that contradicts the title is not treated as a clean specification. US review text is not scored as British opinion. The four weights below sum to 100. The highest score is the top pick. Best value is the strongest price against a UK review that describes a real bottom clean, not the cheapest row.
Amazon evidence
30%Star rating and review count on amazon.co.uk. Fewer than 15 reviews is deducted hard. A details table that prints another ASIN, a battery line that fights the title, or a power field that says ac on a cordless title, is deducted.
Listing fit
35%A floor sentence you can match to a real pool scores. Walls, a waterline, a basket or a micron figure score when the shape limit is also stated. A retrieval handle or hook scores. Conflicting size, milliamp-hour or watt-hour lines lose points. Fields left unstated do not get a guessed value.
Review outcome
20%UK notes that describe a finished clean score. A wheel off, a failed charge, debris thrown back, a robot stuck under a pump, and a warranty described as US-only are deducted. No UK review text keeps this block low.
Value
15%Shelf price in GBP against a listing you can still match to a pool. The lowest price does not win this block when the catalogue size cannot be used, or when the only UK review says the cleaner is not worth £5.
Match the surfaces, the shape and the weight before the brand. On these eleven amazon.co.uk listings the shelf runs from about £76.14 to about £1,699. A floor robot leaves the waterline to a brush. A wall claim still has to fit the shape printed on the page. The [cordless or corded robotic pool cleaner](/hub/pool-care/robotic-pool-cleaner/sub/robotic-pool-cleaner-cordless-vs-corded) page is the battery and a hook against a mains cycle whose cable must reach. Ranking stays on this page.
A robotic pool cleaner is a self-propelled underwater machine that collects debris in its own filter. On amazon.co.uk the usual job is a domestic above-ground pool or a smaller in-ground pool. The first split is floor-only against floor, walls and waterline. The second is cordless against corded. A listing is usable when it states the pool shape, a micron figure if fine dust matters, and a dry weight you can lift. A star line on its own is not that specification.
The Bestway G150, the POOLPURE floor robots, hzexun and YDHZ do not state a wall or waterline claim. A floor robot leaves the scum line to a brush. Read the surfaces the listing names.
Both EVERCROSS U8 listings say not for round or oval pools. AquaGuard SE II and RPC-100A say flat bottoms, not sloped floors or heavy wrinkles. The £88.63 POOLPURE stops at slopes of 8°.
Cordless claims in this set run about 100 to 180 minutes. The Dolphin bullet says about two hours on the mains. None of those figures means the stated pool area is finished on every shape. One G150 review says the run fell to about 20 minutes.
The first check is the surfaces the listing actually names. Floor-only robots in this set include the Bestway G150, whose bullets never claim walls, the POOLPURE floor units, hzexun and YDHZ. They leave the waterline to a brush. Wall claims sit on both EVERCROSS U8 listings, the Aiper raw file, the WYBOT C1 title and the Dolphin Nautilus CC Plus. A wall sentence still has to match the shape. Both EVERCROSS listings say rectangular or square only, not round or oval, up to 200 m².
180 μm is the coarse figure on the EVERCROSS U8-UK3 and on hzexun. The Aiper raw listing adds a 3 μm stage beside 180 μm. “Fine” without a number is not a specification, so the WYBOT file, which states no micron, does not get a guessed grade. A UK review of that WYBOT says fine particles pass through. The U8-2026 states a 6 litre basket and does not state a micron. The G150 states 2 litres and 2.41 kg, and it does not state a micron or a runtime.
Three typical situations, each with a recommendation from this comparison.
You have a rectangular or square pool and you want the floor, the walls and the waterline from a cordless robot you can hook out. The EVERCROSS BOT U8-2026 is about £399.99, with 3.9 from 58 reviews, a 6 litre basket and a 120 minute claim. The listing excludes round and oval pools.
You want a light robot for the bottom of a small round pool, and you will time the first runs yourself. The Bestway AquaTronix G150 is about £95.93 and 2.41 kg, with 4.2 from 60 reviews. One UK review describes a 12 ft round bottom. Runtime is not stated on the listing.
You have an in-ground pool, a socket the cable can reach without an extension, and you want the largest review file. The Dolphin Nautilus CC Plus is about £1,699, with 4.2 from 13,341 reviews and a corded cycle of about two hours. UK notes say the cable can fall short of 50 ft.
The top pick is the EVERCROSS BOT U8-2026 at about £399.99. It claims the floor, the walls and the waterline on rectangular and square pools up to 200 m², with a 6 litre basket, 120 minutes and a retrieval hook, and amazon.co.uk shows 3.9 from 58 reviews. It is not for round or oval pools, and UK notes include a slope that floated the robot off the floor. The best value is the Bestway AquaTronix G150 at about £95.93, with 4.2 from 60 reviews and a UK description of a 12 ft round bottom. Runtime is not stated on that listing. The £76.14 YDHZ is not the value row: the one UK review says it is not worth £5, and the size lines conflict with the 3.63 kg weight.
Bestway AquaTronix G150
About £95.93, with 4.2 from 60 reviews and a UK note of a 12 ft round bottom. Runtime is not stated on the listing.
