An Overview of the Dolphin Nautilus’ Features
These three features are present in all robot pool cleaners. Let’s see how the Dolphin managed to get itself on top of the list.
Design
The Dolphin’s aerodynamic design is its most standing-out feature. It’s the reason why the device plunges into the water with minimal resistance. Plus, the black color adds to the sleek look of the unit.
The outer frame is made out of high-quality plastic, and the bottom is adorned with round brushes for scrubbing. Additionally, the Dolphin features a hidden buoy for floating. And what makes it even more functional is the handle on the top. It enables you to easily maneuver it out of the water. It also helps you effortlessly lift it.
As for power, the Dolphin has a power supply unit that takes up to 25% of its size. The Dolphins power supply is not waterproof, so it doesn’t dive in with the device. Furthermore, the power cord has a length of 60 feet, which should let the device roam around just fine. Besides, it has an anti-tangle feature that lets it swivel freely.
I know what you’re thinking. The cord will tempt you to pull it when you want to lift the device out of the water. But that’s what the top handle is for. Plus, pulling the cord will damage the power supply in the long term.
Robotic Setup
Even in the digital era, robotic devices usually require some effort on your part for assembly and setup. That’s not the case with the Dolphin Nautilus, though. You order a robot cleaner, you get a fully robotic cleaner!
In other words, the Dolphin operates dependably. Once you turn it on and drop it in your pool, it takes it as its cue to start working. You won’t have to do any extra effort, unlike other robot cleaners which may need directing from you. It’ll even shut off on its own when it finishes.
On top of that, the built-in timer enables you to set the cleaning time and go your way. You can choose from three options; clean one time daily, one time every two days, or twice in seven days. Afterward, the Dolphin will operate on its own.
Functionality
When it comes to functionality, the Dolphin Nautilus CC Plus is one of the leading pool cleaners on the market. It fights swimming pool dirt like a champ. Plus, it covers large spaces despite its compact size.
Thanks to CleverClean technology, the Dolphin creates a passage for itself while cleaning. It doesn’t move around randomly sweeping whatever it finds. Instead, it scans the pool’s length and determines a path that’ll allow it to clear the pool out completely. Afterward, it follows its course until it finishes cleaning.
In addition to that, the Dolphin has an obstacle-detecting feature that allows it to move freely without getting hit. If it finds an old toy floating deeply in the pool, it’ll move around it, continuing to help keep your pool clean & beautiful!

The 3 Features That Matter the Most
These three features are the reason that the Dolphin is now globally recognized among the leading robot cleaners. See for yourself how each of them works.
CleverClean Technology
The CC in the name stands for CleverClean; the technology that’s responsible for the high functionality of the Dolphin. It enables the unit to fully clean a pool in around two hours. Plus, the technology saves energy by consuming minimal electric supply in each clean.
CleverClean technology works as follows; the sensors scan the length of the pool to detect a course to follow. The path is then lined, and that’s the device’s cue to start cleaning. Once it’s done, it shuts off automatically and waits for you to lift it out of the pool.
Filtration Process
Most pool cleaners have one common problem. They filter the water by expelling powerful jets from the bottom. While this method proved effective, it has one major side effect. The water that gets thrust out usually carries tiny dirt particles. As a result, the pool’s corners pile up unseen dirt that’s almost impossible to clean.
That’s not the case with the Dolphin Nautilus. It works in the opposite way; the water passes by the bottom and gets pushed out of the top. That way, less debris is expelled with it. Additionally, the Dolphin comes fully equipped with two sets of filters, along with a top-loading filter that wasn’t present in the original Dolphin Nautilus.
The first filter set is a polyester sieve. It’s responsible for large waste, such as tree leaves and insects. On the other hand, the second set consists of ultra-fine filters that clean tiny dirt and dust.
You can switch them whenever you like. However, it’s recommended that you only use the ultra-fine filters when you need deep cleaning.
Pool Cleaner Maintenance
Anything that has to do with a swimming pool requires maintenance. The pool itself demands frequent cleaning, which is why we’re here in the first place! The Dolphin Nautilus is highly convenient, so its ease of cleaning doesn’t come as a surprise.
To clean the filter out, you just need to open its compartment, take it out, and run it under a water stream. Afterward, you put it back where you pulled it out. The thing is, most robot cleaners require you to flip them over to reach the filter compartment. However, you don’t need to go through that with the Dolphin, thanks to its smart design.
As for periodic maintenance, it’s only necessary that you keep the unit out of direct contact with rain. Keeping it out of the sun will also prolong its life and guarantee that the power supply won’t overheat. Other than that, you don’t need to do anything besides regular cleaning.
What Users Liked
Users had a lot to like about the Dolphin. They were impressed by the full automation of the device. On top of that, they loved the Dolphin’s ability to climb walls easily and sweep them clean. You’d think it needs wheels for that, but it actually relies fully on the rear brushes.
Users also commented that the price tag is very reasonable, considering that the device comes with its own booster pump. Additionally, some users praised the Dolphin’s efficiency in cleaning odd-shaped swimming pools.
What Users Didn’t Like
Users mainly complained about the lack of smart add-ons, such as a mobile application and a remote controller. Especially that those features are available in other Dolphin models. Also, some customers wished the device would’ve come with a storage unit, instead of being left out in the open.
Furthermore, users who operated the Dolphin in extra-large swimming pools sometimes had to run it more than twice. They also mentioned that it sometimes didn’t thoroughly clean large spaces from one run.
The Dolphin Nautilus CC Plus Vs. Similar Pool Cleaner Models
If you want to take a look at some similar Dolphin models for assurance, here are two models that are somehow close to the Dolphin but come with higher price tags. But first, check out this awesome commercial and in-use video for the Dolphin Nautilus CC Plus by Maytronics below.
Dolphin Triton PS Plus
The Dolphin Triton is an inground-pool cleaner that works in a similar way to the Dolphin Nautilus. It has the same ultra-fine filter, and it also runs on dual brushes. It surpasses the Dolphin because it enables you to control it via a smartphone app. However, it costs a lot more.
Dolphin Premier
The Dolphin Premier is one of Dolphin’s most smart pool cleaners. It’s loaded with tech features that are designed to make your life easier. For starters, its timer offers more options than the Dolphin Nautilus. Besides, it has an LED light indicator that turns on when the dust bag should be emptied.
The Premier also comes with a remote controller, which the Nautilus lacks. These features are the reason it costs about $400 more than the Nautilus.
Safety Tips for Using the Nautilus CC Plus
If you’re going for the Dolphin, there are some safety precautions that you should consider. Here’s a brief list.

Frequently Asked Questions (FAQs)
These are the questions we most often get about the Dolphin Nautilus CC Plus. If you want to clear out any confusion you have regarding the device, skim through them for answers.
Which Filter Should You Use With The Dolphin Nautilus CC Plus Pool Cleaner?
For the best results, our team recommends that you initially use the leaf filter when you first open the pool for summer or anytime after big storms that blow a lot of leaves or large debris into the pool. For everyday in-season pool cleaning, we recommend that you use the ultra-fine filter with your Dolphin Nautilus CC Plus.
Can The Power Supply Dive Into The Water?
No, it can’t. The power supply unit isn’t waterproof. Therefore, it’ll get damaged if you put it into the pool with the device. That’s also why you shouldn’t leave it out in rainy weather.
Does The Dolphin Nautilus Come With A Cover?
Unfortunately, it doesn’t. It also comes without a transporting caddy. However, those accessories are easy to live without. You can cover it with any piece of cloth while it’s in storage, or purchase a cover for roughly around $50 online.
How Long Is The Cleaning Cycle Of The Dolphin Nautilus CC Plus?
In our experience, the swimming pool cleaning cycle of the Dolphin Nautilus CC Plus is right around 2 hours to 2.5 hours.
What Voltage Should I Plug The Dolphin Into?
The Dolphin Nautilus CC Plus plugs into regular household outlets of 120 volts. We don’t recommend that you use an extension cord when you plug it in. It may mess with the device and cause the cord to overheat.
How Do You Empty The Dolphin Nautilus CC Plus?
First take the Nautilus CC Plus out of the pool and then look for some notches on the top sides of the cleaner that are on the small black panels, separated by the blue middle area, pulling on these should pop open the top. Opening these will allow you to see the filter cartridges, grab the middle tab of each cartridge, wiggle it some and pull them out.
Each filter cartridge will have two filters on it, one on each side, you can remove this by turning the double-hook latches clockwise and gently removing the filters. We then recommend you spray down the filters and cartridges with a hose to remove all of the debris from inside.
Does the Dolphin Nautilus Work For Above-Ground Swimming Pools?
It might work, but that’s definitely not what it’s designed for. Therefore, we can’t assure you it’ll get you the results you want if you try to use it in an above-ground swimming pool. The Dolphin Nautilus CC Plus is made specifically to work for inground pools.
If you want an alternative device that works for above-ground ones, you may want to consider the old Nautilus CC, which was made to work on both inground and above ground pools.
What Surface Types Does The Dolphin Nautilus CC Plus Clean?
The Nautilus CC Plus will work well for all kinds of different swimming pool surfaces, including vinyl and fiberglass.
Can I Swim While The Dolphin Nautilus Is Running?
While technically you can, we do advise against it. You may get tangled with the cord, which may cut the power supply off the device. Plus, your body will serve as an obstacle for the device. So, it’ll spend more time than it should in the process.
What Comes With The Dolphin Nautilus CC Plus?
The Dolphin Nautilus CC plus comes with the Following:

Hello, I am a writer and marketing specialist in Kansas City, MO. My love for swimming pools started as a child when I would visit my aunt & uncle’s inground swimming pool on a frequent basis over the summer. Since then I have taught swimming lessons at a Boy Scout Camp, participated in the full setup, installation and maintenance of my father’s inground swimming pool, as well as enjoyed constantly researching everything there is to know about swimming pools for 5+ years. I enjoy all water related sports, being part of the online swimming pool community and always learning new things!
I am having trouble finding the correct timing belt for my Nautilus CC Plus pool cleaner. My serial number is ” P23653NC6I” AND THE YEAR WAS 04/06/2018. wEB SITES GIVE PART NUMBER AS 9985006, BUT IT IS TOO SHORT. i CAN FORCE IT ONTO THE FRONT AND BACK BRUSH rollers but not enough slack to fit onto the motor gear. I tried to contact a local rep, but no reply. Could use some help.
Charles, thank you for contacting us, I believe the piece you are are looking for is https://www.amazon.com/MAYTRONICS-Dolphin-Cleaner-Replacemen-Number9985006-R2/dp/B09XCJ91FW. It may be worth contacting Maytronics directly at 1-888-365-7446 to double check with your serial number as well.
I see that on Amazon a wifi feature is listed for an additional $20. What does that do? Will it enable me to steer the robot to missed areas or leaves.

I’ve watched a lot of videos on this product and I don’t understand how scheduling the cleaning times on the power module is a “plus”, when you have to physically put the robot into the water anyway. Why make a schedule on the unit rather than just put it in and let it run for the 2 hours it’s programmed to run when you see it needs cleaning? And this model also comes with a wi-fi option that says you can run it from anywhere at anytime by scheduling it with a smartphone. Doesn’t the same thing apply in that you have to physically be there to put it in and pull it out of the water? I have also seen where it says not to pull the unit out of the water by the cord but haven’t seen anyone explain as to how to get the robot back to a place that you can physically pull it out of the water by the handle, when it typically stays on the bottom or goes up and down the walls. This is the unit we want to purchase but still have these questions. Also, our outdoor power outlet is far enough to from the pool, that, because of the short power cord on the unit, we’d have no choice but to use an extension cord. Our pool is 36’ long and, with the distance from the pool to the house, the 50’ cord wouldn’t be enough either and we’d want to leave the power unit on the covered porch by the outlet to keep it out of the elements as suggested. Any feedback would be appreciated. Thanks!!
