What this page is, and what it is not

We have not run these machines in a pool. This is a research comparison built from the makers own specifications and prices, plus published tests we name where we lean on them. Everywhere a number appears here, it came from the seller's own page on the date stamped above.

We are saying that plainly because the alternative is what the rest of this category does. Of the pages currently ranking for this search, most are published either by a company that sells the machine or by a site paid to place it. Our method explains what we will and will not claim, and we would rather be useful and honest than sound more authoritative than we are.

If your question is about a particular maker rather than which machine to buy, start from our brand by brand review index, which covers what we have verified about Beatbot, Dolphin, Aiper, WYBOT and Polaris, and how to tell an honest review in this category from a paid one.

Robotic, automatic, suction side: which one are you actually shopping for?

This trips people up because the words are used loosely. Automatic pool cleaner is the umbrella term for anything that cleans without you pushing it, and it covers three different machines:

• Robotic: self powered, with its own motor and its own filter basket. It works whether or not your pool pump is running.
• Suction side: plugs into the skimmer and borrows suction from your pool pump. Cheap, and useless when the pump is off.
• Pressure side: driven by a booster pump, pushing debris into its own bag.

In practice, when a retailer or a review site says automatic pool cleaner in 2026, they mean a robot. That is why this page covers both terms rather than splitting them: the search results for the two phrases are largely the same pages, and pretending otherwise would just mean writing the same guide twice.

If you have not settled on a type yet, start one step further back: pool vacuums and which of the four types suits your pool sets the four machines side by side, including the two we do not sell, and gets you to the right category before you compare a single model.

Worth settling before you spend anything: a robot competes with the cleaning slice of your pool bill, not with the whole thing. What pool maintenance actually costs breaks the yearly total down and shows which part of it a machine can and cannot touch.

Two price lists that agree on almost nothing else, a national cost guide and a Texas service company, put the same monthly value on the cleaning job itself. That is what a machine is actually bidding against, and the arithmetic is set out on that page rather than repeated here.

One number you will be asked for constantly, and which decides every chemical dose you ever measure, is how much water the pool actually holds. Our pool volume calculator works it out and shows the arithmetic rather than just the answer, including why a kidney shaped pool cannot honestly be given the single multiplier most calculators use. It sells nothing, which is the point of it.

Note that volume is not the number that picks a machine. Makers size cleaners against the pool itself, and they do not even agree on which measure, which is worked through below.

What the money actually buys

The single most useful thing to understand before shopping is that price does not track cleaning quality in a straight line. It tracks how many jobs the machine does. Scrubbing the floor is cheap. Climbing walls costs more. Skimming the surface, mapping the pool and dosing chemicals is where the top of the range goes.

Which band is right for you depends less on budget than on what kind of pool you own. An inground pool has deep walls and a waterline that shows a ring, so the middle bands earn their money: what an inground pool demands covers sizing and surfaces. An above ground pool usually needs far less machine, and the above ground page explains why the expensive features mostly go unused there.

How big a machine do you actually need?

Sizing is the step most roundups skip, and it is the one that decides whether a machine finishes your pool or leaves the far end for tomorrow. The awkward part is that the brands do not agree on what to measure, so the ratings on two product pages are often not comparable at all.

Beatbot rates the AquaSense 2 Pro by surface area, at up to 3,875 square feet on its own product page. Maytronics rates the Nautilus CC Plus by length, at up to 40 feet. Neither figure converts into the other without knowing the shape of your pool, so comparing a square footage rating against a length rating tells you nothing.

What both of them agree on, by omission, is that volume is not the sizing number. Gallons govern your chemistry and your running costs, not your machine choice.

In practice: measure your pool's length and its surface area once, write both down, and check each shortlisted machine against whichever of the two its own maker publishes. If a listing gives you neither, that is worth noticing on its own. Our calculator covers the gallons side, and says plainly that it is the wrong number for this decision.

The axis the comparison tables leave out: warranty

Feature tables in this category compare brushes, navigation and app control. They almost never compare cover, and cover is where the money goes when a three year old machine stops. The reason it gets left out is that it does not fit in a column: the warranty is not one number per brand. It changes between models made by the same company.

Two things follow. The first is that any article giving a brand a single warranty figure is describing one end of its range: Dolphin gets called a three to four year brand routinely, and the machines most buyers are shown carry one. Our Dolphin page works through that range model by model at the maker's own prices.

The second is that an advertised phrase and a written policy are different documents. Beatbot's product page advertises three years with full machine replacement, while the warranty policy behind it is written as repair or replace, with a replacement that may not be new. We did not infer that, we read both.

Our review of the machine we earn on sets out that gap and a second one in the return policy, and issues no confident recommendation as a result.

We deliberately do not list a warranty figure for the AquaSense X below, because its own product page shows more than one and we are not going to pick the flattering number on the maker's behalf.

The machines

Prices below were read off each maker's own store and are stamped with the date. Where we earn a commission, the card says so with a button. Where we do not, the card says that too. Availability was re-checked on the makers' own product pages rather than their category listings, which is a distinction that matters more here than it should.

Best for most in ground pools: Beatbot AquaSense 2 Pro

Cordless, five-in-one cleaning (surface, waterline, floor, walls, water clarification), 22 sensors, rated by Beatbot to 3,875 sq ft (an AREA figure, not a pool length), 3 year cover advertised

$1,899.00 Prices verified August 14, 2026. Confirm the current price on the retailer page before buying.

You cannot buy this one right now. The maker's own page shows it sold out, so we have taken the button off rather than send you to a page you cannot order from. The card stays because the machine has not changed and it will come back.

This is the point in the range where the waterline gets scrubbed without paying for surface skimming as well, which is the capability most inground pools actually need. It is cordless, so there is no cable to untangle, and its maker rates it for pools up to 3,875 square feet, which covers the great majority of domestic pools.

Keep in mind: As of our August sweep this one is Sold Out on Beatbot's own product page, with a Notify Me button in place of the buy button. The category listing still shows no badge at all, so it looks buyable until you open the page.

Best for: An inground pool with a staining waterline, bought by someone who has the shipping date confirmed in writing before paying.

Full specification

Cleaning coverage	Surface, waterline, floor, walls, plus water clarification
Power	Cordless
Sensors	22
Run time (maker figure)	Up to 11 hours of continuous surface cleaning
Rated pool size (maker figure)	Up to 3,875 sq ft. This is an AREA, and Maytronics rates by pool LENGTH, so the two are not comparable
Warranty	Advertised as 3 years with full machine replacement. The written policy behind it says repair or replace, and that a replacement may not be new
Availability	⚠️ SOLD OUT on the maker's own product page as of our August sweep: the buy button is replaced by Notify Me. It was a pre-order in July, so the state has moved from "you wait" to "you cannot order it". The same page still prints "Order now, ships within 24 hours" beside the Sold Out button, and the collection listing shows no badge at all
SKU	PRCFDS02-NA-A

Best for small and above ground pools: Beatbot Sora 30

Cordless, floor cleaning only, two colours at the same price and both in stock, 2 year cover advertised

$689.00 Prices verified August 14, 2026. Confirm the current price on the retailer page before buying.

If your walls stay clean and your complaint is debris on the floor, this does that job and stops there. It is cordless and light enough to lift out without help, and it is the cheapest honest way to find out whether a robot suits your pool at all, which matters more than it sounds: the expensive mistake in this category is buying capability you never use.

Keep in mind: It will not fix a staining waterline, which is the complaint that most often sends people back to the shop. Buying this first and upgrading later costs more than buying the right machine once.

Best for: A small or above ground pool whose walls stay clean, or a first robot bought to test the idea.

Full specification

Cleaning coverage	Floor
Power	Cordless
Variants	Cosmic Orange and Deep Blue, same price, both available
Warranty	2 years on Beatbot's own product page
Availability	In stock. No pre-order or shipping-delay notice on the product page
SKU	RCMPM021-NAA-B (Cosmic Orange), RCMPM021-NAA-A (Deep Blue)

Top of the range: Beatbot AquaSense X

Cordless, cleans surface, waterline, walls, floors and shallow platforms from about 35 cm, 22 L debris basket, AstroRinse station that empties and rinses the filter

This is the machine for a pool that defeats a mid range robot: heavy leaf fall or a large surface. It cleans floor, walls, waterline and surface, and the self cleaning filter station is the real difference, not the cleaning itself. At more than five times the entry model's price, most of that gap buys features rather than better scrubbing.

Keep in mind: Its own product page advertises more than one warranty length, three years in the header and a four year extension tied to a pre-order offer. We quote neither, so read both on the page before you buy.

Best for: A large pool with heavy debris, where emptying the basket by hand is the actual chore.

Full specification

Cleaning coverage	Surface, waterline, walls, floors and shallow platforms about 35 cm and deeper
Power	Cordless
Debris handling	22 L basket, emptied and rinsed by the AstroRinse station
Warranty	Not quoted here on purpose: the product page shows more than one length and we will not pick the flattering number on the maker's behalf
Availability	Add to Cart is live with no pre-order badge. The dated launch copy we recorded in July, "pre-orders ship in late April" plus a deposit schedule dated February and April, is no longer on the page as of our August sweep. We still repeat no shipping window for this product
Variants	AquaSense X, and a bundle with an iSkim skimmer at a higher price
SKU	AquaseneX-NA

That last point is the reason the Dolphin range deserves more than one card. Which Dolphin to buy takes the whole ladder at the maker's own prices, including which models were out of stock and where the warranty jumps from one year to three, and Dolphin against Polaris covers the other incumbent, which publishes twenty eight robotic models and a price on none of them.

One thing that is not on that list, despite how often it is sold as though it were: whether your pool is saltwater. A salt pool is milder than most people assume and modern machines are rated well past it, so it rarely narrows the shortlist at all.

The bottom line

For most in ground pools the AquaSense 2 Pro is the machine that matches the job, provided you get the shipping date in writing first. If your walls stay clean, the Sora 30 does the floor and nothing else for a third of the money.

The AquaSense X only earns its price on a pool that defeats a mid range robot, and its terms are the weakest part of the offer. If a young brand is what worries you, the Dolphin EON 100 buys the service record, at one year of cover instead of three.

Cordless or corded

Every machine above is cordless, which is where the category has moved, but the trade is real. A cordless robot cleans until its battery runs down. A corded one cleans until you stop it. If your pool is large enough that a single session does not finish the job, a cable is not the inconvenience, it is the fix.

That trade deserves more room than a paragraph, so it has its own page: cordless robotic pool cleaners and what the battery actually costs you covers runtime against pool size, which brands sell what, and why a cordless pool vacuum is usually not the same kind of machine at all.

What we would ignore

• Discount framing. Most of this category sits on a permanent sale, so a strikethrough price is not the same as a saving. Compare what you pay today against the other machine you are considering, not against a number the seller chose.
• Extended warranties, accessories and filters. On our affiliate programme none of these pay us anything at all, so we have no reason to push them and every reason to tell you that the warranties exist mainly as margin. Treat any upsell you meet elsewhere accordingly.
• App features you will use twice. Scheduling is genuinely useful. Mapping screens are mostly not, and they are a common source of the disappointment that shows up in first month returns.
• A warranty figure quoted for a whole brand. There is no such number. Cover changes model by model inside every brand on this page, so a sentence beginning "Dolphin gives you" or "Beatbot gives you" is describing one end of a range and hoping you do not check.
• Stock state read off a category listing. A machine on pre-order looks exactly like one in stock until you open its own product page, and the shipping window, where there is one, lives on that page too. This caught us on the first pass and it will catch a buyer faster.

Others we considered

Dolphin Nautilus CC Plus. Maytronics rates it against pool length, at up to 40 feet, and lists one year of cover on its own spec block. It is the model most buyers are shown, and it is the reason the brand's reputation for long cover does not survive contact with its own spec pages.

Dolphin Liberty 400 and 600. These are the models that carry three years on Maytronics' own spec block, three times what the Nautilus and EON models list. They sit further up the price ladder than anything else here, which is why the Dolphin range gets its own page rather than a second card.

Polaris. The other incumbent, and the one we could not price. It publishes twenty eight robotic models and a price on none of them, so there is no figure to put on a card and nothing for a buyer to compare. Dolphin against Polaris covers what that does to a shortlist.
