The best cordless pool robots, compared.
Top pick: AIPER Scuba S1 (2025) – Highest score in the set: 4.4 from 136 reviews, with walls, 180 minutes and both filter grades claimed. The ASIN clash and the moved price stay on the page. Best value: POOLPURE RPC100A (8° slope) – Lowest coherent shelf price whose floor sentence you can match: flat or up to 8°, about £88.63, with a hook. No UK review text in the file. Updated October 2026.
A cordless pool robot drives itself across the pool floor, and on some models the walls, and keeps debris in its own basket. On amazon.co.uk the usual job is a flat above-ground pool, with no cable and no hose. A flat-only robot fails on a hopper, wrinkles stop the drive, and a robot that is too fast throws silt up. Seven listings are compared here from the amazon.co.uk snapshot of 19 . Stars on the cheaper robots sit around 2.8 to 3.5. How to match floor, debris and lift is in the [cordless pool robot buying guide](/hub/pool-care/cordless-pool-robot/sub/cordless-pool-robot-buying-guide). Handheld hoovers and hose jets are a different category and stay out of this table. The floor class is a button or LED start, about 100 minutes, and an IPX8 or IP68 claim. The climber class adds an app and a wall and waterline claim, and it is heavier. The U8 says rectangular and square, not round or oval. Heavy wrinkles and steps are excluded even on the gentler wording. Bestway’s note on its own robot is the practical version of that limit: wrinkles or an unlevel floor stop the drive.

Question 1 of 2
What is the floor like?
The AIPER Scuba S1 (2025) raw row is about £999, with 4.4 stars from 136 reviews, the highest star line and the largest review count in this set. The bullets claim floor, wall and waterline cleaning, 180 minutes, a flow of 15,900 litres per hour, a replaceable 3 μm filter, a 180 micron basket and a 2-year warranty line. Dry weight is 7.7 kg. A spot check on 19 October 2026 showed £549 under a 2026 title, so that later price and the raw £999 are not the same page. The product URL is B0FCFDMQH6 and the technical-details line in the same file prints B0DP6JFJPV. Two UK reviews in the file are short and positive, and one mentions the extra filter pulling out more dirt. Area, charge time and a slope limit are not stated, and the battery line prints 14.52 Wh, which sits oddly beside a 180-minute claim. In this set it is the top pick.
Pros
Cons
Best for: You want the wall-cleaning row with the most reviews, and you will check the live price and the ASIN on the page before you pay.
Less suitable: You need a stated pool area, a stated charge time, or a price that has stayed at the raw £999.
Specifications
Common questions
Which ASIN is on this raw page?
The product URL is B0FCFDMQH6. The technical-details line in the same file prints B0DP6JFJPV. The price in the raw file is £999.
What filtration does the listing claim?
Bullets describe a replaceable 3 μm filter and a standard 180 micron basket. Flow in the title is 15,900 litres per hour. Runtime claimed is 180 minutes.
What do the UK reviews in the file say?
Two UK reviews are short and positive. One mentions the extra filter pulling out more dirt. France and Germany reviews are also in the file and are not UK opinion.
The EVERCROSS BOT U8-2026 is listed at about £399.99, with 3.9 stars from 58 reviews, and it is the mid-price row that claims floor, walls and the waterline. The bullets limit that claim to rectangular and square pools up to 200 m², and they exclude round and oval pools. Runtime is claimed at 120 minutes, the basket is 6 litres, control is by app, and the charge is listed at 4.5 hours. Dry weight is 12 kg, so lifting it clear of an above-ground wall is a two-hand job even before it is wet. One UK review says there was no Bluetooth and no reply from the supplier. Another UK review praises app control and docking. A water-resistance rating is not in the raw file. The shape line is the part you have to match before the wall claim is useful.
Pros
Cons
Best for: Your pool is rectangular or square and you want a wall claim inside this set without the raw £999 AIPER row.
Less suitable: You have a round or oval pool, or you need to lift the robot over a high above-ground wall on your own.
Specifications
Common questions
Will the U8 clean a round pool?
The bullets say it is for rectangular and square pools up to 200 m² and is not suitable for round or oval pools.
How heavy is it to lift out?
The spec table says 12 kg dry and a battery of 783.7 g. The first bullet calls the chassis lightweight. Wet weight is not given.
Do UK owners get the app?
The spec field says control is by app. One UK review says there was no Bluetooth and no reply from the supplier. Another UK review praises app control and docking.
This POOLPURE RPC100A is the lowest-priced floor listing in the set whose floor sentence can still be matched to a pool, at about £88.63, with 3.5 stars from 55 reviews. The bullets allow flat bottoms and gentle slopes up to 8°, a claimed 100 minutes and 900 sq ft, a dry weight of 3.63 kg, and a retrieval hook as well as a floating handle. The review texts saved in the raw file are from the United States, so there is no UK owner comment to quote. The page still says to avoid steep slopes, steps and heavily wrinkled liners. The storage line says recharge at least every three months and do not leave the pack fully depleted. IP68 is a claim on the listing. A US star line is not British opinion, and faults reported on the other POOLPURE rows are not disproved here. In this set it is the best value.
Pros
Cons
Best for: Your floor is flat or within about 8°, and you accept that the written reviews in the file are from the United States.
Less suitable: You want UK owner comments, walls, or a steep hopper.
Specifications
Common questions
Can this POOLPURE robot use a gentle slope?
The bullets allow flat bottoms and gentle slopes up to 8°, including many above-ground and in-ground pools. They still say to avoid steep slopes, steps and heavily wrinkled liners.
Are the written reviews from the UK?
The listing score is 3.5 from 55 ratings. The review texts saved in the raw file are from the United States. There is no UK review text in that file.
How should the battery be stored?
The bullets say store it cool and dry, recharge at least every three months, and do not leave it fully depleted or run it out of water for long.
The POOLPURE RPC-100A sits in the same flat-floor class as the AquaGuard, at about £149, with 3.4 stars from 100 reviews. The bullets claim about 100 minutes, up to 90 m², a 3.8 kg dry weight and a push-button start. UK owners who are pleased say it cleans a flat above-ground floor and keeps the dirt inside the robot. Other UK reviews say it drives too fast and throws debris back into the water instead of collecting it. One UK review says the button often needs many firm presses, and another says it runs for about 20 seconds and then switches off. The page still excludes sloped floors and heavy wrinkles. A floating handle and a park at 5% are claimed, which does not retrieve a unit that has already died in the middle.
Pros
Cons
Best for: You want the flat-floor POOLPURE listing with the most UK reviews, and you can accept a robot that some owners say is too quick.
Less suitable: You need walls, a gentle slope, or a slow pass that does not cloud the water.
Specifications
Common questions
Will the RPC-100A clean an uneven floor?
The bullets limit it to flat above-ground and in-ground pools and say it is not suitable for sloped floors or heavy wrinkles. The listing question about uneven floors has no answer.
Why do some UK owners say it makes the pool worse?
UK reviews say it drives too fast and throws debris up into the water instead of sucking it up. Other UK owners say it cleans a flat above-ground pool well.
Is the on/off button reliable?
One UK review says the button often needs many firm presses. Another says it runs for about 20 seconds and then switches off, and that shaking it only helps briefly.
The POOLPURE AquaGuard SE II is a 3.8 kg floor robot that the raw amazon.co.uk snapshot priced at about £139, with 3.4 stars from 60 reviews. The bullets claim a flat pool up to 90 m² and about 100 minutes, then a recharge of 2.5 to 3 hours. A spot check on 19 October 2026 showed the same listing at £118.15, so the shelf price moves. UK reviews in the raw file report a wheel coming off on first use, a charge that then fails, and a robot that stops after about half a minute while the display still shows a full battery. The listing excludes sloped floors and heavy wrinkles, which rules it out for a hopper or a creased liner. The floating handle and a park at 5% only help if it is still driving. IPX8 is printed as a claim, and it does not mean a cracked case stays sealed.
Pros
Cons
Best for: You have a flat above-ground or in-ground floor and you have read the early wheel and charge complaints before you pay.
Less suitable: Your floor slopes, the liner is heavily wrinkled, or you want UK reviews that describe a trouble-free first season.
Specifications
Common questions
Does the AquaGuard SE II work on a slope?
The listing says it is for flat-bottom above-ground and in-ground pools and is not suitable for sloped floors or heavy wrinkles.
How long does this POOLPURE robot claim to run?
The bullets claim up to 100 minutes from a 5000 mAh pack, and a recharge of 2.5–3 hours. The spec table lists 3 hours and 56 Wh.
What do UK reviewers say goes wrong?
Of four UK reviews in the raw file, owners report a wheel coming off on first use, charging then failing, and the robot stopping after about half a minute while the battery still shows full.
The YDHZ listing is about £81.62 and 3.3 from 9 reviews, and the title claims 120 minutes and 1,000 sq ft on above-ground or flat in-ground pools. The spec table then prints battery and size figures that conflict with a 3.63 kg weight and a lithium-ion description, so those table lines are not specifications. The title’s runtime cannot be checked against the table. The only UK review in the raw file says the cleaner is not worth £5, let alone the price paid, and it gives no further fault detail. Charge time and a water-resistance rating are not stated. Self-parking is claimed in the title. Nine reviews and a broken spec table are why this row sits below the POOLPURE floor robots, even though the shelf price is the lowest.
Pros
Cons
Best for: You are only comparing prices and you will not treat the spec table as a battery or a size.
Less suitable: You need a floor sentence, a battery figure and a review file you can use.
Specifications
Common questions
Can the battery figures on this listing be used?
The spec table prints figures that conflict with the weight and with a lithium-ion description. Those fields are not a usable battery or size. The title’s 120 minutes is a claim, not a reconciled spec.
What did the UK review say?
The only UK review in the raw file says the cleaner is not worth £5, let alone the price paid. It gives no further fault detail.
Which pools does the title claim?
Above-ground pools and flat in-ground pools up to 1,000 square feet, with auto-parking. A water-resistance rating is not in the raw file.
The green POOLPURE RPC100A is listed at about £149 and 2.8 from 13 ratings, the lowest star line in this set. The bullets match the white flat-floor rows: about 100 minutes, up to 90 m², roughly 3.8 kg, and a ban on slopes and heavy wrinkles. The title adds a green shell and detachable wheels. One UK reviewer with a 24 x 12 ft above-ground pool said it has no tidy pattern, needed two runs, and still called the result a good job, while wanting a longer runtime. Thirteen ratings is a thin sample next to the white listing’s 100 reviews. Voltage and watt hours are not in this raw file. Colour is the difference you can see. The rating is not an improvement on the white twins.
Pros
Cons
Best for: You want this green shell for a flat pool and you treat 13 ratings as a small sample.
Less suitable: You want the larger UK review file, a slope, or a stated battery capacity.
Specifications
Common questions
How is the green RPC100A different from the white POOLPURE listings?
The title adds a green shell and detachable wheels. Runtime, 90 m² and the flat-floor limit match the other POOLPURE bullets. Voltage and watt hours are not in this raw file.
Does it cover a 24 x 12 ft above-ground pool in one run?
One UK reviewer with that pool size said it has no tidy pattern and needed two runs, and still called the clean a good job.
What is the star rating on this listing?
The raw file shows 2.8 out of 5 from 13 ratings, lower than the white POOLPURE rows in this set.
Seven amazon.co.uk listings were scored on 19 October 2026 from the raw snapshot, the review notes in the display file, and a same-day spot check of B0G1Y8TZC2 and B0FCFDMQH6. There was no laboratory clean. Area, runtime and IP ratings are listing claims. Amazon evidence, listing fit, review outcome and value are weighted 30, 35, 20 and 15. A small review count, reviews that are not from the United Kingdom, and a spec table that contradicts the title are deducted. US review text is not scored as British opinion.

A cordless pool robot is a battery cleaner that drives the floor, and on some models the walls, and keeps debris in its own basket. On these seven amazon.co.uk listings the shelf runs from about £81.62 to about £999 in the raw snapshot of 19 October 2026. Area lines and star counts are not a pool test. Start with the floor you actually have, then whether you need walls, then whether you can lift the robot out and whether the reviews are from the UK.
A cordless pool robot drives itself on the pool floor, and on some models the walls, and keeps debris in its own basket. UK shoppers on amazon.co.uk mostly want that for a flat above-ground pool, without a cable or a hose. Handheld hoovers and hose jets are a different category and stay out of this table. The floor class is a button or LED start, about 100 minutes, and an IPX8 or IP68 claim. The climber class adds an app and a wall and waterline claim, and it is heavier.
90 m², 200 m², 900 sq ft and 1,000 sq ft are listing claims. They are not a measured clean. Match the floor and the shape first, then the runtime against a charge of 2.5 to 4.5 hours.
The AquaGuard, the white RPC-100A and the green shell exclude slopes and heavy wrinkles. Only the about £88.63 POOLPURE listing allows a gentle slope up to 8°, and it still excludes steep slopes, steps and heavy wrinkles.
Use the original charger, a 30 mA RCD, and keep the charger at least 3.5 m from the water, as Maytronics states for a Liberty. Stop if the case is hot, swollen or cracked. Call an electrician for a new socket in the pool zones.
The floor sentence is the first filter. A flat-only robot fails on a hopper. Wrinkles stop the drive. In this set the AquaGuard, the white RPC-100A and the green RPC100A say flat floors and exclude slopes and heavy wrinkles. The POOLPURE listing at about £88.63 allows flat bottoms and gentle slopes up to 8°, and it still says to avoid steep slopes, steps and heavily wrinkled liners. Shape is a separate line.
Runtime claims in this set are about 100 minutes on the floor robots, 120 minutes on the U8 and the YDHZ title, and 180 minutes on the AIPER row. Charge times that are actually printed run from 2.5 hours to 4.5 hours, so a second cycle is not instant. The YDHZ title’s 120 minutes cannot be checked against a spec table that conflicts with a 3.63 kg weight. Treat every minute figure as a claim. Filter and retrieval decide what you get back.
Three typical situations, each with a recommendation from this comparison.
You have a flat floor, or a gentle slope within about 8°, and you can live with mixed reliability in this price band. The POOLPURE listing at about £88.63 is the floor sentence you can still match. Written reviews in that file are from the United States.
You want a wall and waterline claim and you will check the live price and the ASIN on the page. The AIPER Scuba S1 row has the strongest star line here. The raw shelf is about £999. A later spot check the same day said £549.
Your pool is rectangular or square, not round or oval, and you can lift a 12 kg dry robot over the wall. The EVERCROSS U8 claims floor, walls and the waterline at about £399.99. UK reviews disagree on whether the app connects.
The top pick is the AIPER Scuba S1 row. It has 4.4 from 136 reviews, and the bullets claim walls, 180 minutes, a 3 μm filter and a 180 micron basket. The raw price is about £999. A spot check on 19 October 2026 showed £549 under a 2026 title, and the URL ASIN does not match the spec-table ASIN. The best value is the POOLPURE listing at about £88.63, because the floor sentence allows a flat bottom or a slope up to 8° and the spec table can still be used. Its written reviews are from the United States. The YDHZ row is cheaper, at about £81.62, and its spec table conflicts with the title, so the lowest price is not the bargain. None of these scores is a lab test.
AIPER Scuba S1 (2025)
Highest score in the set: 4.4 from 136 reviews, with walls, 180 minutes and both filter grades claimed. The ASIN clash and the moved price stay on the page.
POOLPURE RPC100A (8° slope)
Lowest coherent shelf price whose floor sentence you can match: flat or up to 8°, about £88.63, with a hook. No UK review text in the file.
