Thinking about a Dolphin Nautilus robot? Before you click buy on that listing, there are three things Maytronics doesn't put front and center that you need to know before you choose your next pool robot — and one of them could cost you thousands of dollars if you pick the wrong robot.
Hey there, and welcome back to the Pool Nerd. I'm Justin, your resident pool aficionado. If you haven't run into us before, we review all the top pool gear — from robotic cleaners to UV disinfection to water chemistry. And today we're doing something a little different. Instead of one robot, we're breaking down the entire Dolphin Nautilus lineup: the CC, the CC Plus, the CC Pro, the CC Titan, and the CC Supreme.
The Nautilus Lineup at a Glance
Here's every Nautilus robot Maytronics sells right now, entry level on up. Each one links straight to my full review, and you can check the going price on any of them — just read the warranty section below before you buy from a marketplace listing.
Every Dolphin Nautilus, Model by Model
And here's the short version of everything that follows: every robot in that chart ships with a one-year warranty. These are the Max-Series and ProLine models I'd hand you instead — two or three years of coverage, NanoFilters, and timers that aren't buried in an app.
My Picks Over the Nautilus CC Line
I've tested more than 30 robotic pool cleaners at this point, and the Nautilus CC line comes up in almost every conversation I have with a new pool owner. It's popular, it's from a brand I trust, and those prices look mighty tempting.
But here's the thing — every model in this line makes the same three compromises. Once you see them, you'll understand why I almost always point people toward a different Dolphin. So stick around, because I'm going to walk through each model, what it does well, where it falls short, and exactly which robot I'd grab instead.
Where the Nautilus CC Line Fits
The Nautilus CC is Maytronics' budget line, often sold on online marketplaces like Amazon and Walmart — the value tier that lives below their new Max-Series and the ProLine. And to be fair, these are still Dolphins. They're plug-and-play, they run efficient DC motors, and in my testing every one of them did a solid job scrubbing pool floors. If your one and only goal is a clean floor and you're on a tight budget, a Nautilus will get you there.
One note before we go model by model: this guide covers the five in-ground CC robots. Dolphin also sells two above-ground Nautilus units, the Nautilus AG and the Nautilus Pool Up, which carry the same one-year warranty. I cover both further down, and if that's your pool, my best above-ground robotic pool cleaners guide is the better starting point.
But most of us don't buy a robot just for the floor. We want the walls, we want the waterline, and — this is the big one — we want to stop babysitting the thing. That's where the cracks start to show, and they show up in the same three spots on every model in this family.
The Three Compromises Every CC Shares
So let me lay these out, because they're the whole reason I put this guide together.
Number One: The Warranty
This is the one that can bite you. Maytronics just silently updated every Nautilus robot to a 1-year warranty across ALL models. Whether you buy the entry-level Dolphin Nautilus CC or the $1,500 Dolphin Nautilus CC Titan, you get the same short 1-year warranty. And this is a big deal.
Compare that to the ProLine Premier or Sigma, which both carry a full three years. On a robot where a replacement motor or power supply can run you three to four hundred dollars, in my opinion that extra coverage is worth it — I'd put it at two hundred dollars or more, easy.
And here's the kicker on warranty. That full coverage only counts when you buy from an Authorized Maytronics Dealer. From what I've seen, if you buy the exact same robot from a random third-party seller — and that includes a lot of listings over on Amazon — Maytronics may only honor a limited one-year warranty, or none at all. Same robot, same box, wildly different protection. That's why I never tell folks to just grab the cheapest listing they can find.
⚠ Warning — The Amazon Warranty Trap: Buying a Dolphin from an unauthorized seller — including many third-party Amazon listings — can leave you with as little as a one-year warranty, or no coverage at all. Maytronics only honors the full manufacturer's warranty through Authorized Dealers. Always confirm the seller is authorized before you buy. I break down exactly how this plays out in Stop Buying Pool Robots on Amazon.
Number Two: No NanoFilters
And this matters more than people think. NanoFilters — these pleated, high-efficiency cartridges — are exclusive to models like the Premier, Sigma, and Quantum. The whole Nautilus line runs mainly on standard fine filters, and while a couple of the higher Nautilus models add an ultra-fine kit, they don't have what Dolphin calls NanoFilters.
If your pool ever fights cloudy water, fine dust, sand, or the early stages of algae, that filtration gap is something you will notice in the water.
Number Three: The Timer Situation
And this one's a little sneaky. The base Nautilus CC used to come with a Weekly Timer, and Maytronics quietly dropped it. What was, is no more. Now the base CC runs on a single-button power supply — you press it, it cleans for about two hours, and then you're walking back out to start it by hand every single day.
The app-connected Nautilus models bring a timer back, but they bury it inside the myDolphin Plus app and strip out the simple scheduling right there on the power supply. Either way, you lose that dead-simple "set it on the box and forget it" automation. And that stings, because the Max-Series Cayman hands you exactly that at a similar price — and with a 50% longer warranty than every Nautilus robot.
Dolphin Nautilus CC
This is the entry point, usually starting around six hundred dollars. It's light — under fifteen pounds — with an active scrubbing brush, CleverClean navigation, and a top-load filter basket that's easy to rinse out. In my testing it did a nice job on the floor and the lower walls.
But it has only partial wall climbing and no waterline scrubbing at all, so the dirtiest part of your pool — that scum line — gets left for you to brush by hand. No weekly timer, no NanoFilters.
Where I land: it's a fine floor cleaner for a small pool on a budget, but you're giving up a lot to save those dollars. And it only has the 1-year warranty. My full breakdown is in the Dolphin Nautilus CC review, and if you're cross-shopping the entry level, the Escape vs Nautilus CC comparison is the one to read.
Dolphin Nautilus CC Plus
Step up and you get a robot rated for larger pools, up to fifty feet, with a higher flow rate and dual filtration. The newer units now ship with Wi-Fi built into the power supply. Sounds like a real upgrade — but in my experience the CC Plus still misses the waterline, same as the base CC.
The filters are dual cartridge filters, and it doesn't include NanoFilters. And it only has a 1-year warranty.
There's more detail in my Dolphin Nautilus CC Plus review, plus head-to-head breakdowns against the Quantum and the Premier.
Dolphin Nautilus CC Pro
Now we finally get waterline cleaning, plus Wi-Fi and the myDolphin Plus app. On paper, that's a real step up.
Still just one filter option, still no NanoFilters, and Dolphin cut the warranty down to 1 year. In my opinion, that's a lot of give-and-take for the money. Especially when for not much more, you can get the longer 2-year warranty and XXL MaxBin with NanoFilters in the Dolphin Quantum.
A standalone CC Pro review is still on my list — until then you can check the current Nautilus CC Pro price and use the lineup comparison below to see where it lands against its siblings.
Dolphin Nautilus CC Titan
This is the muscle of the CC line. It pushes the highest flow rate of the bunch, it cleans the waterline, and it comes with a weekly timer and the app. On raw performance, in my testing it's the strongest Nautilus robot you can buy.
But — and this one caught me off guard — Maytronics lists it with a one-year warranty. One year, on a premium-priced robot. No true NanoFilters either.
Powerful? Absolutely. But that warranty is a tough pill to swallow when a ProLine model gives you three years for not much more. My full testing notes are in the Dolphin Nautilus Titan review.
Dolphin Nautilus CC Supreme
The top of the CC line. Full floor, wall, and waterline cleaning, the myDolphin Plus app, a weekly timer, and multiple cleaning modes. So what's the catch? It still has a 1-year warranty.
At what the Supreme costs, you're sitting right in Dolphin Premier and Sigma territory — robots that give you NanoFilters, commercial-grade motors, and in the Premier's case a swappable Multi-Media system and a leaf bag, not to mention a longer 3-year warranty.
I go deeper on this one in the Dolphin Nautilus CC Supreme review.
Dolphin Nautilus AG (and the Pool Up)
If your pool sits above ground, the two Nautilus models to know are the AG and the Pool Up. The AG is the newer of the pair — roughly 22 by 17.5 inches, about 15 pounds, rated for pools up to 33 feet, with the same active scrubbing brush and top-load filter basket as the base CC and a cycle that wraps up in about an hour and a half. Maytronics is upfront that it doesn't do walls or the waterline, which is what you'd expect on a soft-wall pool with a vinyl liner.
The Nautilus Pool Up is the older above-ground option, and it runs a filter bag instead of a basket. Both carry the same one-year warranty as every other robot on this page. My Pool Up review is live now and the AG review is coming — in the meantime you can check the current Nautilus AG price, and if you're shopping this category, start with my best above-ground robotic pool cleaners guide.

If you want to see these robots measured against something outside the Nautilus family, I've got four head-to-head breakdowns that cover the questions I get most: Nautilus CC Plus vs Quantum, Nautilus CC Plus vs Premier, Escape vs Nautilus CC Plus, and Escape vs Nautilus CC.
Why the Upgrade to Max-Series and ProLine Is Worth It
So if not the Nautilus CC, then what? Let me point you to the two lineups I'd reach for instead — the same five robots from the chart up top, in more detail.
Dolphin Cayman — Best Value
If you want the best value in the whole Dolphin catalog, look at the Max-Series. The Dolphin Cayman is my go-to budget pick — it comes with a Weekly Smart Timer right on the box, wall climbing, the oversized top-loading MaxBin, and NanoFilters available as a free upgrade from select dealers. Plus you get a 2-year warranty, not the shorter 1 year.
Dolphin Escape — Entry-Level
For a smaller pool that doesn't need waterline cleaning, the Dolphin Escape is the entry-level model I hand out most often. It gives you that true set-and-forget experience the CC line makes you work for, along with the same 2-year warranty.
Dolphin Quantum — Best Inground
And if you've got a bigger or more demanding pool, step into the ProLine. The Dolphin Quantum is the no-regrets choice — it's the one Dolphin that's both ProLine and Max-Series, with the biggest filter in the lineup, NanoFilters in the box, waterline cleaning, and a built-in weekly timer.
Dolphin Premier — Best Overall
The Premier is my personal number one for its commercial motors and Multi-Media filtration. You can swap between a NanoFilter, standard filters, an oversized leaf bag, and disposable bags in seconds, and it carries the full 3-year warranty.
Dolphin Sigma — Most Advanced
And the Sigma sits at the very top for anyone who wants the absolute best of the best — triple commercial-grade motors, gyroscope navigation, and full app scheduling, with 3 years of coverage behind it.
Buy Authorized, Then Check Open Box
Here's the part that ties it all together: buy from an Authorized Maytronics Dealer. That's how you lock in the full warranty, and it's how you unlock one of my favorite money-savers — Certified Open Box and Refurbished units. These come fully tested with the complete 2- or 3-year warranty you would have gotten with a new robot.
You can save hundreds on a Quantum or a Premier and still end up with more coverage than a brand-new Nautilus CC bought from some random seller. I keep the best deals I dig up on my deals page.
★ Pro Tip — Buy Authorized, Then Check Open Box: Buy from an Authorized Maytronics Dealer to guarantee your full warranty — then check their Certified Open Box and Refurbished listings. In my experience these units perform like new, ship with the complete warranty, and can save you hundreds versus buying new at retail.
Final Verdict
So what's my final verdict on the Dolphin Nautilus lineup?
These aren't bad robots. Every one of them is a real Dolphin, and every one of them will clean your pool floor well. If you're on the tightest budget and you only need floors, a Nautilus CC will do the job. But across the entire line, you're paying for compromises: shorter or riskier warranties, no true NanoFilters, and automation that's either missing or locked behind an app. In almost every case, I'd rather see you spend a little smarter — a Cayman or Escape from the Max-Series, or a Quantum, Premier, or Sigma from the ProLine — and buy it from a dealer who stands behind it.
That's my full rundown of the Nautilus CC lineup. If you wanna keep nerding out over your pool, head on over to my deals page at ThePoolNerd.com/deals, where I post the best deals on robotic pool cleaners and all the top pool equipment. Until next time — enjoy that pool.
