Every “best pool robot brand” list starts from the same place: the name you already know. So let’s start somewhere else — with the number that name actually earns.

Dolphin has the worst owner ratings of any pool robot brand we cover, on the deepest owner base of any pool robot brand we cover. Eight machines, 6,952 owners, a 3.86-star owner-weighted average — and in-ground, where most people meet the brand, it drops to 3.79, dragged there by the Nautilus CC Plus that nearly three quarters of those owners bought. Beatbot leads at 4.20, with Aiper and WYBOT level at 4.12 — a top three separated by eight hundredths of a star, which is another way of saying no brand here is winning this on owner ratings.

That is the most contrarian thing on this page and it comes entirely from reads we already did and dated. It is also the exact shape of a trap we have written about before: the most established name accumulates the most reviews, and review volume is not quality.

But the interesting part is what happens when you ask the question one class down.

The above-ground question changes the answer

Above-ground pools are a different fight, and until we scored them separately we had the brand ordering wrong.

Our robot coverage is split across two classes — machines built for in-ground pools, and machines built or rated for above-ground ones. A brand scorecard that quietly counts only the in-ground half is not a brand scorecard, and that is the version we nearly published: it would have shown Aiper at 4.21, Beatbot at 4.20, WYBOT at 4.12 and Dolphin at 3.79 — with a different brand on top of the table than the honest one puts there.

Fold both classes in and the top of the table changes hands. Aiper drops from 4.21 to 4.12 — because its above-ground machines — the Seagull SE at 3.9 stars across 1,016 owners, the deepest base the brand has anywhere, and the Scuba SE at 4.4 across 242 on a pooled, Vine-seeded base — average 4.00 across 1,258 owners. That fall is what costs Aiper the top of the table: on in-ground machines alone it leads at 4.21, and folding both classes in puts it eight hundredths behind Beatbot and level with WYBOT. Dolphin climbs from 3.79 to 3.86, because its above-ground machines average 3.98 — and one of those two, the Escape, is the best-proven machine the brand has anywhere. Beatbot and WYBOT do not move at all, because neither makes one.

And then the belts:

Dolphin holds exactly one of the nine fights we have ruled, and it is the above-ground one. In-ground, across six machines, it holds nothing. Beatbot holds six. The legacy brand’s only win is in the class the market leader does not enter.

How this scorecard is scored

We have not lab-tested these machines, and no row on this page pretends otherwise. Every scored row carries a stated basis, and every figure is computed at build time from the same dated owner-rating reads and published verdicts that drive the product cards elsewhere on this site — so a rating refresh cannot leave this table quietly disagreeing with the rest of the site.

Two of the rows are deliberately renamed from the obvious version:

• “Cleaning” is “Owner proof.” We cannot score cleaning, because we have not run these robots side by side in the same pool. What we can score is what owners report at scale, and calling the row what it actually measures is the whole position.

• “Overall” is “Belts held.” An overall winner implies a test we did not run. A belt is a verdict we did make, in public, against named rivals — and you can click through and check it.

• “App” is scored on the last 12 months, not the store badge. The badge is a lifetime average, and MyDolphin Plus has been on the App Store since 2019 — long enough for an app to be graded largely on how it behaved years ago. The row uses the mean of every written US App Store review in the trailing 12 months instead, which is the same read-the-base discipline we apply to the robots themselves.

Two rows are not scored at all, and they are shown anyway with the reason in place of a number. Navigation is the clearest case: every spec sheet in this category says “AI vision” or “smart mapping”, none of them share a unit, and no independent test covers all four brands. We would rather ship an honest blank than an opinion in a table.

The app row is the one that surprised us

We expected the app row to be a formality. It is the most interesting row on the page, because the brand with the best-looking app score has the worst-rated app of the four right now.

MyDolphin Plus carries a 4.77-star lifetime badge across 28,470 ratings on the two stores combined — by a distance the most-rated app in this category, and on the face of it a rout. Read the last twelve months instead and that same app averages 1.43 stars across 172 written reviews, 88% of which rate it one or two stars. That is not a small sample or a stale one: it is the deepest recent sample of any app here, and the fifty most recent of those reviews all landed inside 59 days. Maytronics’ newer app, Maytronics One — the one that runs its cordless EON line — reads 1.89. The scorecard blends the two into a single Dolphin figure weighted by review volume, which is why the table reads 1.48 where this paragraph reads 1.43: one is the brand, the other is its main app.

Beatbot’s app leads the row at 4.11, and it is the only one of the four whose current reviews match its lifetime badge rather than falling away from it. Aiper sits at 3.28. WYBOT reads 1.36, which is the one number on this page that surprised nobody: it is consistent with its 1.8-star badge on both stores, and consistent with everything else owners report about that brand.

Two things make the Dolphin figure worth trusting rather than dismissing. It reproduces across two independent stores and two independent populations — the iOS badge says 4.7, the Google Play badge says 4.8, and both platforms’ recent written reviews collapse the same way. And the complaints are specific and repeated rather than diffuse: the robot dropping off the app mid-cycle, having to sign in repeatedly to change a cleaning mode, and a 2.4GHz-only power supply that takes the app down with it when it cannot connect.

This is the same trap as the headline finding, one layer down. A long-lived product accumulates a favourable aggregate, and the aggregate keeps being displayed long after it stops describing the thing. It is why we read bases instead of averages, and it is why this row is scored the way it is.

The caveats that belong with the numbers

Dolphin’s in-ground rating is essentially one product. The Nautilus CC Plus’s owner base is 72% of Dolphin’s entire in-ground base, so the 3.79 is mostly the CC Plus’s rating wearing a brand label. That does not weaken the finding — the CC Plus is Dolphin’s volume seller, and it is the machine most Dolphin buyers actually end up with — but the page should not imply six machines independently converged on the same number. Fold in the above-ground line and the concentration falls to 47%, which is another reason not to read either figure without knowing which class it covers.

One Dolphin rating is not usable for a brand claim at all. The Nautilus EON 120D reads 3.4 stars on 19 ratings, of which roughly 62% are Amazon Vine reviews — free product, and Vine skews high, so a 3.4 there reads worse than it looks. It is far too thin and too incentivised to carry weight either way. Excluding it changes Dolphin’s average by less than a hundredth of a star, which is the honest reason to leave it in and label it rather than argue about it.

WYBOT’s range spans 1.6 to 4.5 stars and the low end is four ratings. That 1.6 is the WYBOT S2, which is a published SKIP on this site and a base far too thin to rank on — it moves the brand average by nothing, since it is 4 owners out of 1,416. The real WYBOT caveat is not a number: it is that owner reports of unanswered warranty email cluster brand-wide, across products, right around the two-year warranty edge. WYBOT publishes more filtration data than anyone here and answers less email than anyone here, and both of those are worth knowing before you buy.

Dolphin’s E10 rating is not a read of the E10. Its Amazon listing re-pooled in August 2026 into a variant parent spanning the whole Explorer E-series — the E10 at $568 through the E50 at $1,629 — so the 3.6 stars across 907 global ratings describe six machines across three price tiers. We publish it flagged rather than dropped, because a pooled figure is a listing’s resting state, but Dolphin’s above-ground case rests on the Escape and its 1,520 owners, not on this.

Aiper’s Scuba S3 rating is pooled across marketplaces. It is flagged global in our data, which means the base includes non-US reviewers. It is a small part of Aiper’s total and does not move the ordering.

What each brand is actually good at

Dolphin — buy it above-ground, think twice in-ground

Dolphin’s above-ground machines are the strongest thing the brand has, and they are strong on exactly the axis that matters most in this category: proof. The Escape holds our above-ground verdict on 1,520 owners, the deepest base of any above-ground robot we card (only Dolphin’s own corded CC Plus, at 3,260, runs deeper anywhere), and it is corded — so there is no battery to degrade, which in a category where every cordless machine is effectively a consumable is a real structural advantage rather than a spec-sheet one.

For most of 2026 it was also the only Dolphin that cleared our proven bar at all — in-ground, the brand fielded nothing rating 4.0 stars or better on more than 100 owners. That changed when we added the corded Dolphin Advantage, which reads 4.4 stars across 962 owners at about $669 and is now the brand’s cheapest proven machine, in-ground or out. One caveat travels with it and it is the reason the finding is softened rather than reversed: that 4.4 is pooled across three machines on one listing (Advantage, Ultra and Pro, $669 to $999), so it is not a clean read of the $669 unit. Dolphin’s in-ground case is better than it was; it still rests on a number you cannot fully attribute. We work through that in the corded showdown.

The software is the brand’s weak point, and the Escape sidesteps it entirely — Maytronics’ own spec sheet lists it as “Mobile Application: No”, so the machine we recommend is the one that never asks you to open the app that its owners rate worst. If you buy a Dolphin that does have one, check which app it needs before you buy: the corded Nautilus CC Plus runs MyDolphin Plus and the cordless EON 120D runs the newer Maytronics One, and they are separate apps with separate problems.

Dolphin Escape Robotic Pool Cleaner (2026)

Best overall

Your pick if you want a robot that just works for years on an above-ground pool and don't mind a cord or the price — the most-proven pick here, with no battery to wear out.

4.2 · 1,520 owner ratingsAmazon · August 2026

“Simple set up, easy use, good quality.”— Robert A. Krull, Amazon

Pro review “In my testing, it's the best above-ground robotic pool cleaner on the market—and a legitimate option for smaller inground pools up to 33 feet.”— Justin D., The Pool Nerd

Pros

• The most-proven pick here — 4.2 stars across 1,520 owners, the deepest base in the category by far
• No battery to die: it's corded, so it runs its full cycle and there's no sealed pack to replace down the road
• Built by Maytronics specifically for above-ground pools — dual motors, an active scrubbing brush, and a big top-load filter owners find easy to rinse

Cons

• The priciest pick here (about $699) — real money for an above-ground pool, where a cheap cordless does the basic job for a fifth of that
• You manage a floating cord, and it's a heavier unit to lift in and out
• Floor-focused — it scrubs and cleans the bottom well but isn't a dedicated wall/waterline climber

What owners complain aboutDefect reports

It tips onto its back wheels and misses floor, and it will not do the steps and walls some buyers expect; separately, the external power supply is the part that dies.

Beatbot — the division record, at a price

Beatbot holds six of the nine fights we have ruled, publishes a micron figure on six of seven machines, and its flagships rate as well as anything in the category. It is the most decorated brand here by a distance.

It also wins the app row outright, and it is the only brand here that does not have to explain a gap between its store badge and its recent reviews — 4.11 stars across the last twelve months against a 4.03 lifetime iOS badge. For a category where every flagship feature is delivered through software, that is worth more than the row’s position on the page suggests.

The catch the scorecard exposed when this page first ran was cost of entry, and it has since closed. In August 2026 Beatbot’s cheapest machine rating 4.0 or better on more than 100 owners was the $1,899 AquaSense 2 Pro; its keenly-priced models were well rated, but on bases under 100, which our own evidence-depth rule flags as early data. Those bases caught up. The Sora 10 now reads 4.1 stars across 155 owners at about $449, on a clean single-listing base, and the Sora 30 reads 4.5 across 217 at about $689 — so the brand’s proof and its affordable machines are the same machines now. What has not moved is the ceiling: the flagships still start at $1,899, and the Pro’s own base shrank to 69 owners when its listing was replaced.

Beatbot AquaSense 2 Pro

Best cordless overall

Your pick if you're ready to pay for cordless surface skimming and ultrasonic mapping — a 5-in-1 clean and a 3-year warranty; testers do question paying this much over a corded robot.

4.0 · 69 owner ratingsAmazon · September 2026 · early data · global base

“The benchmark for high-end cordless, with its camera and waterline mode.”— Pool Planet

Pro review “The surface cleaning capability alone justifies the investment for anyone dealing with constant leaf debris or surface contamination.”— Vincent Nguyen, The Gadgeteer

Pros

• Most capable cordless here — floor, walls, waterline, surface skimming, and water clarification (5-in-1)
• Genuinely smart ultrasonic mapping (SonicSense), not random bouncing
• Self-parks at the surface and returns on one app tap
• 3-year full-replacement warranty

Cons

• Still a splurge — testers question whether any cordless robot earns this price over a corded one
• Owner-review quality is hard to verify (third-party authenticity tools flag its listings)
• Cordless means recharging between cycles on very large pools

What owners complain aboutCapability limit

It strands itself on steps and on main-drain covers, its path reads as random rather than mapped, and several owners report it never surface-parks the way the listing shows.

Aiper — the most proven mid-price machine in the category

Aiper’s in-ground line reads 4.21 across 1,771 owners — the best of the four by a hundredth over Beatbot, and the most fragile number on this page. It rests on the Scuba S1, which used to carry 4.5 stars across 804 owners for around $500, and it is the clearest example on this page of why a brand average is only as stable as the listings under it: in August 2026 its Amazon listing was replaced outright, and the deepest one still selling the machine reads 4.3 stars across 837 on a base that read about 69% free-product Vine when we last checked its composition. The robot did not change. The S1 lost our Welterweight belt to the Beatbot Sora 10 on that read, and Aiper lost first place on this table with it.

Aiper is also the only brand besides Dolphin that sells to above-ground owners at all — though both of its above-ground machines are floor-only cordless cleaners. The Seagull SE at 3.9 stars, on the brand’s deepest base, is what pulls the brand average down when both classes are counted; the Scuba SE’s 4.4 sits on a pooled, Vine-seeded base of 242 and cannot lift it back.

Aiper Scuba S1

Best value

Your pick if you want a long-runtime cordless robot at about $500 and you judge it on the machine rather than the star average — its deep 4.3★/837 base carries a heavy free-product Vine share (four of ten visible cards at the September 2026 read), so the number is softer than it looks; best for light-debris pools, not heavy silt or the biggest pools.

“I picked up a S1 a few weeks ago and have been very impressed. It cleans just as good as my old Maytronics, for half the price and no cord.”— JJ_Tex, verified owner (Trouble Free Pool)

Pros

• Excellent price-to-performance
• Cleans the waterline too
• Long runtime for the price (~270 min floor-only; ~150 min combined)
• Easy to live with

Cons

• Testers ding fine-debris pickup on very silty pools
• Best for light-debris pools; weaker than corded models
• Navigation/app less refined than the premium tier

What owners complain aboutLifespan

The durability reports are the thing to read, and almost all of them are European: batteries dead inside a year, units failing after one or two seasons, one first defect after five uses. The two US cards are different - one owner ran it three times on an 8,000-gallon pool and the pool was still dirty. Worth weighing against a headline rating that is itself heavily Vine-seeded.

⚠ Safety watchNo recall on the Scuba S1. Aiper HAS recalled two other cordless robots for charging fires: Elite Pro (#23784, Aug 2023) and Seagull Pro (#25187, Mar 2025) — both records opened; neither names the S1. CPSC recall API re-checked 2026-09-04 (saferproducts.gov/RestWebServices/Recall, ProductName=Aiper → 2 records, both other models). Class queries the same sitting: "robotic pool cleaner" and "pool cleaner" return only Aiper Seagull Pro #25187; "pool skimmer" returns 0. Positive control: "Aiper" returns its two robot recalls (#23784 Elite Pro 2023, #25187 Seagull Pro 2025), so a zero is a real answer. Buy current stock, use the supplied charger, and charge away from anything flammable.

WYBOT — cheapest way into a proven machine, with a brand-level asterisk

WYBOT has the lowest cost of entry here by a wide margin: the C1 is about $400 and reads 4.0 stars across 948 ratings, which is a deeper base than anything Beatbot fields. It publishes a micron rating on all five machines we card, more than any other brand.

The asterisk is service. The pattern in owner reports is consistent enough across WYBOT products, and clustered tightly enough around the warranty boundary, that we treat it as a brand-level caveat rather than a product-level one, and we have paused adding new WYBOT products until it changes. The hardware is good value. The thing you are also buying is a support relationship, and that is the part with the complaints.

WYBOT C1 Cordless Robotic Pool Cleaner

Proven in-ground value

Your pick if you have an in-ground pool and want a proven budget cordless robot — 4-in-1 to ~1,615 sq ft, and The Pool Nerd's runner-up cordless under $500 — and you'll accept a shorter ~150-min real runtime and a modest 4.0★ owner score for the tester endorsements.

4.0 · 948 owner ratingsAmazon · September 2026 · listing-wide base · incentivised base · global base

“In short, it wildly exceeded my expectations. It completely blows away the much more expensive Active 20 at wall climbing and waterline scrubbing. It's not even close.”— Gyre (Trouble Free Pool)

Pro review “The Wybot C1 is the runner-up. At ~$420, you get floor, wall, and waterline cleaning—coverage that used to require a $600+ corded Dolphin.”— Justin D., The Pool Nerd

Pros

• 4-in-1 cleaning — floor, walls, and waterline — with smart path navigation that maps the pool instead of bouncing at random, covering in-ground pools up to 1,615 sq ft
• The testers' budget pick: The Pool Nerd ranks it the runner-up cordless under $500 — its value alternative when the Sora 10 isn't on sale — and The Gadgeteer says it 'hits the sweet spot'
• A dependable value at ~$400 (reg $570) with a proven feature set — the safe in-ground choice in a tier full of gambles

Cons

• Shorter real runtime than the spec-sheet leaders — about 150 minutes per full clean versus the 210–300 floor-mode minutes rivals advertise; fine for an average pool, tight for a big one
• One rigorous tester (Robotic Reviews) was lukewarm — 65/100, dinging the constant recharging, motor strength they called 'rather lackluster,' and an app 'not close to other pool robots we have tested'
• The replaceable-battery edge is gone: the battery is user-serviceable, but WYBOT no longer stocks a genuine replacement pack (brand-store check 2026-07-16), so you can't simply buy an official pack — plan ownership math as effectively sealed. The owner base is also global rather than US-only (884 ratings, about a quarter of the visible reviews free-product Vine), so read it as a broad average rather than a clean US read
• WYBOT brand flag — three issues (verified 2026-07-20): (1) Questionable customer service — warranty claims frequently go unanswered, clustering right at the 2-year warranty edge ("multiple emails sent to Wybot… no response", "they dont honor their warranty"); one C1 owner is the exception, reporting a fast replacement. (2) Relisting / Amazon-Vine-seeding — WYBOT pads fresh listings with free-product Vine reviews and its ASINs drift often (the B1's rosy 4.7★/65 sits on a ~77%-Vine relisting; the newer C1 listing runs ~80% Vine), so read the review base before trusting any WYBOT star rating. (3) Battery reliability with no genuine replacement — packs fade and WYBOT sells no purchasable genuine replacement (the batteries are user-serviceable, but no pack is sold in its US/EU stores or on Amazon), so the robot is the consumable. Buy where returns are easy and don't count on post-warranty help.

What owners complain aboutFit / placement

It strands itself — on a tanning shelf, or in the corner where the deep-end floor meets the wall — and the ~120-minute battery does not finish a larger pool.

✓ Safety: no active recallThe WYBOT C1 is not part of any recall. Note: WYBOT's S1 (model WY200) and Osprey 700 Max were recalled by CPSC in April 2026 for lithium-battery fire/burn hazards — the C1 is a separate model and isn't named, but confirm you're buying the C1 and charge any cordless robot somewhere sensible.

Polaris — a footnote, not a column

Three robots and 763 owners, and all three are good: the cordless FREEDOM Plus is the testers’ pick in its class at 4.4 stars on a thin 63-owner base, the corded PCX 868 iQ reads 4.2 on 72, and the corded 9450 Sport reads 4.0 stars across 628 owners and holds our corded verdict — which, taken together, is a 4.05-star brand average that would place Polaris mid-table if we scored it. We still do not, and the reason is breadth of evidence rather than depth: 628 of those 763 owners are one machine, and the other two bases are two-digit. The four scored brands field five to eight robots each across multiple weight classes, which is what makes a row like “belts held” or “cost of entry” mean anything. Polaris is a real contender in the fights it enters — it just does not yet have the proven bases to be scored as a brand, and if its second and third machines reach three-digit owner bases that changes.

Which brand should you actually buy?

The honest answer is that the question is one level too high. Nobody buys a brand; they buy a machine, for a specific pool, at a specific price. What the scorecard is good for is knowing what you are walking into:

• Above-ground pool? Dolphin or Aiper, because the other two do not make one. Start with the above-ground robot showdown — the corded Escape wins it, and the wrinkled-liner question matters more than the brand does.
• In-ground, and you want the most proof per dollar? This is the row August 2026 changed. It used to be Aiper’s Scuba S1, on the deepest owner base in its class — then that listing was replaced outright and the deepest surviving one turned out to be ~69% free-product Vine, the weakest score in its own division. The belt went to the Beatbot Sora 10, which does not post the highest number in the class either (the WYBOT C2 does, on a global base padded with free product) but is the only one there whose rating describes a single machine. Read the smart-value showdown for how that was decided — it is the clearest worked example on this site of why a base beats an average.
• In-ground, on a budget? WYBOT’s C1 is the cheapest genuinely proven machine in the category, with the service caveat above. It won the budget cordless division.
• Spending flagship money? Beatbot, which holds the premium and heavyweight classes and publishes the filtration numbers to back it.
• Set on a corded machine? The corded showdown settles that half of the category — and finds that going corded moves the failure point rather than removing it.
• Buying on the strength of the name alone? That is the one this page exists to argue with.

If you want the machine rather than the brand, the pound-for-pound robot showdown settles corded against cordless across the whole category.
