Best robotic pool cleaner UK: the job, then the skip

Updated: 21 October 2026

Best on a UK search page usually means the dearest machine with the longest star line. That is how a robot at about £1,699 ends up in the basket for a 12 ft round pool it was not listed for. The best robotic pool cleaner UK question in this set is which amazon.co.uk job matches your pool, and who should skip that row. Prices and review counts are the figures for these eleven ASINs, checked on 19 October 2026. This is not a lab test. If you buy through our links, we may earn a commission at no extra cost to you.

Best is a job, not a trophy

Three jobs cover this set: a small flat bottom, a rectangular pool where you want walls from a battery, and an in-ground pool on a mains cable. Name the job first. The top pick is the EVERCROSS BOT U8-2026 at about £399.99, for rectangular walls: a 6 litre basket, 120 minutes and 3.9 from 58 reviews. The best value is the Bestway AquaTronix G150 at about £95.93, for a small flat bottom, 4.2 from 60. A round pool should skip the top pick. A waterline should skip the best value. The question order is the robotic pool cleaner buying guide.

Flat above-ground floors

For a flat bottom, start under about £160. This band will not finish a scum line. The Bestway G150, ASIN B0FMQD2N5B, is about £95.93 and 2.41 kg, 4.2 from 60. Runtime is not stated. One UK review says 30 to 40 minutes on a 12 ft round bottom. Another says about 20 minutes later. The POOLPURE at about £88.63 claims 100 minutes and slopes to 8°, at 3.5 from 55, with no UK review text in the file. AquaGuard SE II at about £139 and RPC-100A at about £149 claim flat pools up to 90 m² and exclude wrinkles. UK notes include a wheel off, a failed charge, and debris thrown back.

Walls and a battery

If the waterline is the job, the floor robots are the wrong shortlist. The U8-2026 at about £399.99 claims floor, walls and waterline on rectangular and square pools up to 200 m², at 12 kg. UK notes include only three walls finished, a float off a slope, and doubt about UK customer service. Skip it for a round or oval pool. The U8-UK3 at about £339.99 prints 180 micron mesh at 4.7 from 14 reviews. Do not crown that over 3.9 from 58. The WYBOT C1 at about £649 is 3.9 from 679, and the power field says ac beside a cordless title. The Aiper raw file at about £999 on B0FCFDMQH6 is 4.4 from 136, with a 3 μm filter and a 180 micron filter. The details table prints ASIN B0DP6JFJPV.

Corded, and the largest review count

The Dolphin Nautilus CC Plus at about £1,699 is 4.2 from 13,341 reviews, the largest sample. It is corded, for in-ground pools up to 50 ft, with about two hours on the mains, at 9.45 kg. UK reviews say the cable falls short once the run to the socket and the depth are used. An extension is forbidden. Several say cover was then called invalid in the UK or valid only in the US. If that line is refused, the Consumer Rights Act 2015 is the claim against the trader. Cable reach is on cordless vs corded pool cleaner. The day you run it is how to use a robotic pool cleaner.

Common questions

Which robot is the one for a small flat above-ground pool?
In this set that job is the Bestway AquaTronix G150 at about £95.93, 4.2 from 60, 2.41 kg, if you can accept a runtime that is not stated. One UK review describes the bottom of a 12 ft round pool for 30 to 40 minutes. Another says the run later fell to about 20 minutes. The POOLPURE at about £88.63 states 100 minutes and slopes to 8°, and it has no UK review text. Walls are not what either row is for, so a stained waterline still needs a brush.
Is the 4.7 EVERCROSS better than the 3.9 EVERCROSS?
The 4.7 is the U8-UK3, from 14 reviews, with one UK note and a stated 180 micron mesh at about £339.99. The 3.9 is the U8-2026, from 58 reviews, at about £399.99, with a hook and mixed UK notes on slopes and support. A higher star line on a smaller file is not a win by itself. The top pick sits on the larger file. You should still skip both if the pool is round or oval.
Is the cheapest robot a bargain?
The YDHZ at about £76.14 is 3.3 from 9 reviews. The listing prints 25 x 25 x 25 mm and a 1 g battery beside 3.63 kg. The one UK review says it is not worth £5, let alone the price paid. A low shelf price does not repair a catalogue you cannot match to a robot you can lift. It is not the best value row. The best value row is the Bestway at about £95.93.
What should I skip if my pool is round?
Skip both EVERCROSS U8 listings. They say they are not for round or oval pools, including the top pick at about £399.99. The Dolphin title is in-ground up to 50 ft, which is not this set’s above-ground recommendation. Start with a floor robot that does not ban a round outline, and do not paste another Bestway model’s size limit onto the G150.
Does a high star rating mean the warranty works in the UK?
No. The Dolphin’s 4.2 from 13,341 sits next to UK reviews that say cover was refused as US-only after a failure. The Aiper two-year line is a sentence on that file, not a confirmed UK workshop. Your route against the seller, if the goods are faulty, is the Consumer Rights Act 2015, which is separate from a brand service centre.
