Which Dolphin pool cleaner to buy

By the BackyardRated Editorial Team
Published July 29, 2026 and updated August 19, 2026

The short answer. Two things separate the Dolphin range usefully, and neither is the model name. The first is coverage: whether a machine cleans floor and walls, or floor, walls and the waterline where the visible ring forms. The second is the warranty, and it is not one number.

On Maytronics' own US store the Nautilus CC Plus, the EON 100 and the EON 120d each list one year, while the Liberty cordless models list three. Brand comparisons that quote three to four years for Dolphin are describing the top of the range, not the machines a buyer is usually shown first.

Get coverage and warranty right and the rest of the ladder is navigation, filter handling and app control, which change how pleasant the machine is to own rather than how clean the pool ends up.

Our picks at a glance

The range, at the maker's own prices

Every figure below was read off Maytronics' own US store rather than a reseller or a comparison article, because resellers and comparison articles disagree with the maker and with each other. Two models were listed out of stock on the day we read it, which is worth knowing before a reseller sells you one.

The warranty is not one number, and that is the finding

This is the part worth taking away, because it is repeated wrongly almost everywhere. Read the specification block on each product page on the maker's own store and the warranty field changes between models in the same brand. The corded Nautilus machines we checked and the cordless EON machines we checked each state one year. The Liberty cordless models state three.

That matters most exactly where buyers compare on price. A top Nautilus and an entry Liberty can land close enough to each other that the decision looks like a coin toss on features, and the warranty is the argument nobody puts in the comparison table. It is also the reason to be careful with any article, including the well known ones, that gives this brand a single warranty figure.

Five models, one brand, and a three to one spread in cover. These are the five whose specification blocks we read ourselves; the rest of the range is left off rather than assumed.

What each step up actually buys

The one step that changes the cleaning result comes early: moving from a machine that cleans floor and walls to one that also cleans the waterline. The waterline is where body oils, sunscreen and airborne dust collect into a band that shows long before the floor looks dirty, and a machine that ignores it leaves you the one job you can see from a sun lounger.

The step up What it adds Cleaning, or comfort?
Floor and walls, to floor, walls and the waterline The band where body oils, sunscreen and airborne dust collect, which shows long before the floor looks dirty Cleaning. The one step that changes the result
Bouncing, to scanning A planned route instead of a random one Comfort
Bottom filters, to top mounted ones Lifting the basket out without turning the machine over Comfort
No app, to app control Scheduling and control from a phone Comfort

Those additions are real, and they are worth money to some owners and nothing to others, which is why the honest version of this page will not rank them for you.

Our main comparison sets the whole category against price bands, and the cordless page covers the battery trade that decides between the Nautilus and Liberty families.

Three models that mark the range

These are three points on the curve rather than a shortlist, and none of them earns us anything. We have no affiliate relationship with Maytronics, so there is no button on any of these cards and no link to their store anywhere on this site.

The one most roundups lead with: Dolphin Nautilus CC Plus w/Wi-Fi

Corded, cleans floor and walls, app control, 1 year cover on Maytronics' own spec block, in stock when we checked

$799.00 Prices verified August 14, 2026. Confirm the current price on the retailer page before buying.

We earn nothing if you buy this one. We have no affiliate link with this brand, so there is no button here.

This is the model the category writes about, and for a pool whose walls are the problem it does the job for the least money of anything with an app. It is corded, so it runs as long as the cycle needs. Read what it does not do first: the ring at the waterline stays, and that is the step most owners are trying to automate away.

Keep in mind: Cover is one year on Maytronics' own spec block, a third of what the Liberty models in the same range carry.

Best for: A pool with dirty walls and a clean waterline, and an owner who wants the established brand cheaply.

Top of the corded ladder: Dolphin Nautilus CC Supreme

Corded, cleans floor, walls and waterline, in stock when we checked, warranty NOT stated by us because we did not read one for this model

$1,149.00 Prices verified August 14, 2026. Confirm the current price on the retailer page before buying.

We earn nothing if you buy this one. We have no affiliate link with this brand, so there is no button here.

The waterline is the difference between a pool that looks cleaned and one that looks maintained, and this is the cheapest way to get it from this brand without a battery. Corded means it runs as long as the cycle needs, which on a large pool is the argument that beats every feature list. It is roughly twice the entry price for a ladder whose upper steps are mostly navigation.

Keep in mind: We did not read a warranty figure for this specific model, and this brand's cover changes between models in the same range. Ask before buying rather than borrowing a sibling's number.

Best for: A larger pool with a visible waterline ring, where session length matters more than tidiness of cable.

Cordless, and the long warranty: Dolphin Liberty 600

Cordless, 3 year cover on Maytronics' own listing, price taken from our last verified sweep because the product page publishes none

$1,729.00 Prices verified August 14, 2026. Confirm the current price on the retailer page before buying.

On a battery machine the warranty is the specification, because the one part guaranteed to wear out is the one that ends the cleaner. Three years is three times what the Nautilus models we checked carry, from the brand with the longest service record here. It is also the most expensive machine on this page, and the Liberty ladder above and below it is genuinely hard to read.

Keep in mind: A battery machine on a large pool can stop before the job is done, so check the runtime against your pool length before you buy.

Best for: A large pool where you want cordless convenience and are buying the cover rather than the brushes.

Where a Beatbot beats a Dolphin, and where it does not

We should be explicit here, because this is the page where our own commercial interest sits. Beatbot is the one brand on this site we earn a commission on, and it is the natural alternative to a mid range Dolphin. So: the honest version.

Where Beatbot wins. The hardware combination is genuinely unmatched at the top of its range, with surface skimming, wall and floor cleaning and water clarifying in one machine where Dolphin sells those as separate categories. Its headline warranty is longer than the one year the Nautilus machines carry.

Where Dolphin wins, and it is not close. Service. Maytronics has the longest established spares and repair network in the category, which is the thing that matters most in year three, and Beatbot's support runs through returns rather than through a technician near you.

And our own reading of Beatbot's paperwork found a return policy that grants a thirty day return while also excluding sale items on a permanently discounted range, plus a warranty advertised as full machine replacement but written as repair or replace with a replacement that may not be new.

Our review of the machine we earn on issues no confident recommendation, for reasons set out there in full.

What we could not verify

Stated plainly, because a page that only lists what it knows is easy to mistake for a page that knows everything. We did not read a warranty figure for the Nautilus CC Pro, the Titan, the CC Supreme, the Escape or the Active 15, so none is stated for them.

We could not re-read the Liberty prices today, because those product pages carry no price at all. We have tested none of these machines ourselves, and this page does not pretend otherwise: our method sets out what we do and do not claim.

Frequently asked questions

Which Dolphin pool cleaner should I buy?

Decide on two things before you look at a model number: whether you need waterline cleaning as well as floor and walls, and how long the warranty on that specific model runs. Those two split the range far more usefully than the names do. Everything above the entry rung is mostly better navigation and easier filter handling, which are comfort features rather than cleaning ones.

How long is the warranty on a Dolphin?

It depends on the model, and it is not the number most comparison articles quote. On Maytronics' own US store the Nautilus CC Plus, the Nautilus EON 100 and the EON 120d each list a warranty of one year, while the Liberty cordless models list three.

Articles that describe the brand as carrying three to four years are describing the top of the range, not the machines most people are shown first.

What is the difference between the Nautilus and Liberty ranges?

Nautilus is the corded family and Liberty is the cordless one, and the practical gap is longer than the names suggest: on the maker's own listings the Liberty models carry a three year warranty against the Nautilus one year. If you were choosing between a top Nautilus and an entry Liberty on price alone, the warranty is the argument you were not given.

Is a more expensive Dolphin better at cleaning?

Up to a point, and the point comes early. The step that changes the result is going from a model that cleans floor and walls to one that also cleans the waterline, because the waterline is where the visible ring forms. Steps above that buy navigation, filter access and app control, which make the machine pleasanter to own rather than better at cleaning.

Are Dolphin cleaners actually in stock?

Not all of them, and the maker's own store is the place to check rather than a reseller. When we read the range, the Dolphin Escape and the Dolphin Active 15 were both listed as out of stock on Maytronics' own site while the rest of the range was available. A reseller listing can show an out of stock model as buyable for weeks.
