Dolphin Nautilus CC Plus: Versions, Specs and Alternatives

The Dolphin Nautilus CC Plus is the model most pool owners land on when they search for a robotic pool cleaner, and it is also the one with the most confusing listings. The same name covers a plain robot, a bundle with a storage caddy and a Wi-Fi version with extra filters, and the listings do not even agree on how long a pool the robot suits. Buy the wrong one and you either pay for a feature you will not use or find out the filters you ordered do not fit.

This page is the model guide. It sets the three versions side by side, explains how the CC Plus differs from the older Nautilus CC, lists the parts that fit, and says plainly who should look at another robot. For a short verdict on the whole range, see our Dolphin pool cleaner reviews; for other makers, start with the best robotic pool cleaners.

Dolphin Nautilus CC Plus: The Quick Answer

For a standard inground pool, the classic Nautilus CC Plus is the one to buy: a corded robot that climbs walls, scrubs with an active brush and has a top-load filter basket you empty without tools. Add the caddy bundle only if you want somewhere to store and wheel the robot. Pick the Wi-Fi version only if scheduling from your phone matters to you, because that and the ultra-fine filter panels are what you pay for.

Skip it if you want no cable at all, if you need the waterline or steps cleaned and the listing for your version does not say so, or if your pool is small enough that a lighter Dolphin does the same job. The sections below give the detail.

Nautilus CC Plus Versions Compared

Three listings use the Nautilus CC Plus name: the classic robot, the robot bundled with a caddy and cover, and the Wi-Fi model. The table shows only what each listing states. One difference needs a warning up front. The classic listing says inground pools up to 40 ft, while the caddy and Wi-Fi listings say up to 50 ft. We cannot tell from the listings whether the robot differs or only the wording does, so if your pool is between 40 and 50 ft, check Dolphin's own page for the exact model number before you order.

Dolphin Nautilus CC Plus, Reviewed

The classic robot gets the full review, because the other two versions are this robot with something added. The caddy bundle and the Wi-Fi model follow with a short review each.

Top pick · Best for a standard inground pool

Dolphin Nautilus CC Plus

The sensible default for an inground pool up to 40 ft. It is a plug-and-play corded robot with the features most owners actually use, and no app to set up.

• $$$ Premium
• Pool length Up to 40 ft
• Pool type Inground
• Filter Top-load filter basket
• Walls Wall climbing

Check price on Amazon

Buy it if

You have a standard inground pool, you want the pool cleaned without a routine of your own, and you do not need an app.

Skip it if

You want no cable, you need steps or the waterline cleaned and your listing does not say so, or your pool is longer than 40 ft by the classic listing.

The Nautilus CC Plus is built around three ideas, and Dolphin states all of them in the listing. It climbs walls, so the sides of the pool are cleaned and not only the floor. It has an active scrubbing brush, which the listing describes as removing manual effort while staying gentle on surfaces. And it has a top-load filter basket, so you lift the lid and empty the debris without taking the robot apart.

Setup is the other half of the pitch. The listing calls it plug-and-play: plug in, drop the robot into the pool, power on, and Dolphin says the pool is clean in 2 hours. That is the maker's cycle figure, and a pool with heavy leaf fall will not always follow it, so treat it as the target and not a promise.

The classic listing rates the robot for inground pools up to 40 ft in length. The listed item weight is about 20.8 lb, which is worth knowing because you lift this robot out of the water every time you service it, and it comes out full of water. The cable is the cost of a corded design: you will manage a swivel and a length of cord around the deck.

What the classic listing does not say matters just as much. It does not mention Wi-Fi, an app, waterline scrubbing, steps or sun ledges. That does not prove the robot lacks them; it means the listing is silent, and you should check Dolphin's own page if one of them decides your purchase. If an app does decide it, the Wi-Fi version below is the one to read about.

This is the robot to buy when the goal is simple: a clean inground pool, a filter that is easy to empty, and no software to maintain. If your needs are more specific than that, one of the other versions, or another robot, will fit better.

What stands out

• Wall climbing and an active scrubbing brush, per the listing
• Top-load filter basket you empty without tools
• Plug-and-play: no app or setup
• Dolphin states a 2-hour clean cycle

Trade-offs

• Corded, so you manage the cable
• Listing is silent on Wi-Fi, waterline and steps
• Classic listing says up to 40 ft, shorter than the other two versions

2

Best for storage and moving

Dolphin Nautilus CC Plus with Caddy

The classic robot with a place to put it. The listing adds the Universal Caddy and a Classic Caddy Cover to protect, transport and store the cleaner.

• $$$ Premium
• Pool length Up to 50 ft
• Pool type All pools, per listing
• Filter Top-load filter basket
• Walls Wall climbing

Check price on Amazon

Buy it if

You do not want to carry a wet robot to the shed, and you want the cleaner covered between uses.

Skip it if

You already have somewhere to store the robot, or you only want the cleaner itself.

The caddy bundle is the classic Nautilus CC Plus with a wheeled caddy and a cover, which is why the listing describes it as a way to protect your investment. A corded robot is heavy and wet when it comes out of the pool, and a caddy turns that into a short roll instead of a lift.

Read the listing carefully before you assume it is a bigger robot. It says the bundle is ideal for all pools up to 50 ft, where the classic listing says inground pools up to 40 ft. The feature list is also shorter: it keeps wall climbing and the top-load filter basket, but does not repeat the active scrubbing brush. We cannot say from the listings whether the robot itself differs, so confirm the model number with Dolphin if the pool length decides your purchase.

What stands out

• Caddy and cover included for storage and transport
• Listed for pools up to 50 ft
• Same wall climbing and top-load filter basket

Trade-offs

• Listing does not repeat the scrubbing brush
• The extra is storage, not cleaning performance

3

Best for app scheduling

Dolphin Nautilus CC Plus Wi-Fi

The one to buy if you want the pool cleaned on a schedule without walking outside to start it. It is listed with always-connected Wi-Fi and added ultra-fine filter panels.

• $$$ Premium
• Pool length Up to 50 ft
• Pool type Inground
• Wi-Fi Always-connected Wi-Fi, scheduling
• Filter Ultra-fine filter panels included

Check price on Amazon

Buy it if

You want to set a cleaning schedule from your phone, and finer filtration is worth paying for.

Skip it if

You are happy to plug the robot in yourself, or you would rather not depend on home Wi-Fi reaching the pool.

The Wi-Fi model keeps the CC Plus body and adds two things. The first is connectivity: the listing says you can schedule pool cleanings from anywhere over an always-connected Wi-Fi link. The second is filtration: ultra-fine filter panels are included, which the listing describes as an additional filtration option on top of the standard setup.

It is listed for inground pools up to 50 ft in length. The listing does not name the app, so check the maker's page for the app and the Wi-Fi band it needs before you buy. Wi-Fi also has a practical limit that no listing mentions: the signal has to reach the pool equipment, and a weak connection at the back of the yard will undo the convenience.

What stands out

• Scheduling from your phone, per the listing
• Ultra-fine filter panels included
• Listed for inground pools up to 50 ft

Trade-offs

• App and Wi-Fi band not stated in the listing
• Needs home Wi-Fi that reaches the pool

Nautilus CC vs Nautilus CC Plus

The Nautilus CC is the older, plainer sibling, and the two are easy to mix up. On the page they look alike: both listings promise wall climbing, an active scrubbing brush, a top-load filter basket and the same 2-hour plug-and-play clean. The differences are in what the listings rate and what they fit.

Pool Length and Pool Type

The Nautilus CC listing rates the robot for pools up to 33 ft and names both above-ground and inground pools. The classic CC Plus listing says inground pools up to 40 ft. If your pool is between 33 and 40 ft, that gap is the main reason to step up.

Filters Do Not Swap

This is the difference that costs people money. The ultra-fine filter panels listed for the CC Plus say they are not compatible with the Nautilus CC, and the CC Plus appears on their compatibility list instead. If you own a CC and are shopping for filters, or you own a CC Plus and found a cheap CC filter, check the compatibility line before you order.

Weight and Warranty

The Nautilus CC listing gives an item weight of about 14.8 lb and a 1 year warranty. The classic CC Plus listing gives about 20.8 lb and does not state a warranty. Treat the weights as listing figures, since they may include different packaging.

4

Best for a smaller pool, above or inground

Dolphin Nautilus CC

The one to compare the CC Plus against. It is listed for both above-ground and inground pools, but only up to 33 ft, and its filter panels differ from the CC Plus.

Check price on Amazon

Buy it if

Your pool is 33 ft or shorter, and the listing's mention of above-ground pools matters to you.

Skip it if

Your pool is longer than 33 ft, or you want to share filters with a CC Plus.

The Nautilus CC listing states wall climbing, an active scrubbing brush, a top-load filter basket and the same plug-and-play routine as the CC Plus. It is listed for above-ground and inground pools up to 33 ft, and gives a 1 year warranty and an item weight of about 14.8 lb. The listing does not mention Wi-Fi or waterline cleaning.

Choose it only if the shorter rating covers your pool. If you are near the limit, the extra length of the CC Plus is the safer margin.

What stands out

• Listed for above-ground and inground pools
• 1 year warranty stated
• Lighter listing weight than the CC Plus

Trade-offs

• Rated up to 33 ft only
• Ultra-fine panels for the CC Plus do not fit it

Filters and Replacement Parts

A robotic pool cleaner lasts as long as you can keep buying its filters, brushes and tracks. The three Maytronics-certified parts below are the ones people search for. One warning applies to all of them: part numbers and compatibility lists are exactly where a wrong guess costs you, so read the compatibility line before you order.

• Ultra-fine filter basketCheck the CC Plus is on the list.
• Ultra-fine filter panels, 4-packNames the Nautilus CC Plus.
• Nautilus CC Plus tune-up kitFilters, brushes, rings and tracks.

5

Check fit first

Dolphin Ultra-Fine Filter Basket

A genuine Maytronics ultra-fine filter basket assembly. Its compatibility list names the Nautilus CC, CC Pro and CC Supreme, but not the CC Plus.

• $ Budget

Check price on Amazon

Buy it if

You own one of the models on its list and want a finer basket.

Skip it if

You own a CC Plus and have not confirmed with Dolphin that this basket fits.

The listing describes a replacement ultra-fine filter basket assembly and a long compatibility list that includes Nautilus CC, Nautilus CC Pro and Nautilus CC Supreme, among others. The Nautilus CC Plus is not on that list by name. That is the fact to hold on to: it may well fit, but the listing does not say so, so confirm before you buy.

What stands out

• Maytronics Certified Genuine Part
• Compatibility list is published in the listing

Trade-offs

• Nautilus CC Plus is not named on the compatibility list

6

Best for CC Plus filtration

Dolphin Ultra-Fine Filter Panels (4)

The replacement filters to look for. The listing is a 4-pack of ultra-fine panels that names the Nautilus CC Plus and the CC Supreme as compatible.

• $ Budget

Check price on Amazon

Buy it if

You own a CC Plus and want to refresh the filtration, or you want the finer filtering the Wi-Fi version ships with.

Skip it if

You own a plain Nautilus CC: the listing says the panels are not compatible with it.

This is the clearest answer to the question "where can I find Nautilus CC Plus filters". The listing names the Nautilus CC Plus in its compatibility list, alongside the CC Supreme and many other Dolphin models, and says outright that it does not fit the Nautilus CC. It is sold as a pack of four ultra-fine panels and carries the Maytronics Certified Genuine Parts label.

What stands out

• Names the Nautilus CC Plus as compatible
• Pack of four panels
• Genuine Maytronics part

Trade-offs

• Not compatible with the Nautilus CC, per the listing

7

Best for a full refresh

Dolphin Nautilus CC Plus Tune-Up Kit

The all-in-one option. The kit bundles fine and ultra-fine filter panels, grey brushes, climbing rings and tracks for the Nautilus CC Plus.

• $ Budget

Check price on Amazon

Buy it if

Your CC Plus has seen a few seasons and you would rather replace the wearing parts together.

Skip it if

Only a filter is worn: the panels alone are the smaller purchase.

The listing says the kit is compatible with the Nautilus CC Plus and names its contents by part number: fine filter panels 9991433-R4, ultra-fine filter panels 9991432-R4, grey brushes 6101641-R2, climbing rings 6101611-R4 and tracks 9985006-R2. Dolphin's description explains the split: the fine panels catch larger debris such as leaves and twigs, the ultra-fine panels catch dirt and sand, and the brushes, rings and tracks keep the robot scrubbing and gripping the walls as they wear.

What stands out

• Made for the Nautilus CC Plus by name
• Covers filters, brushes, rings and tracks
• Part numbers listed for reordering

Trade-offs

• More than you need if only one part is worn

Who Should Skip It: Cordless and Smaller-Pool Alternatives

The CC Plus is a corded robot with a clear job. It is the wrong buy in two cases: you do not want a cable, or your pool is smaller than the robot you would be paying for.

If You Want No Cable

The cordless Nautilus EON 120D removes the cord entirely. Its listing states up to 4.5 hours of runtime, a built-in Wi-Fi connection with the MaytronicsOne app, waterline and sun ledge cleaning (down to 8 in), stairs and corners, and an automatic return to the pool edge at the end of the cycle. It is listed for pools up to 50 ft. The classic CC Plus listing says nothing about the waterline or steps, so that is where the EON earns its place. Our cordless pool cleaner guide compares the cordless models.

If Your Pool Is Smaller or Mid-Size

The Proteus DX3 is not a bigger robot: its listing rates it for inground pools up to 33 ft, shorter than the CC Plus. It uses the same wording for wall climbing, an active scrubbing brush and a top-load filter basket. If your pool is 33 ft or less, it can be the better fit; for a pool longer than 33 ft, the CC Plus is the safer choice. For longer pools, look at the versions rated up to 50 ft, and see our inground pool cleaner guide for other makers.

Best cordless alternative

Dolphin Nautilus EON 120D

The one to buy instead if the cable is the problem. It is cordless, Wi-Fi connected and listed for the waterline, stairs and shallow sun ledges.

• $$$ Premium

Check price on Amazon

Buy it if

You want no cord to manage, and your pool has steps, sun ledges or a waterline you want cleaned.

Skip it if

A corded robot with no app is enough for your pool, or you want the simplest setup.

The EON 120D is a different kind of robot, and the listing shows it. It runs on a battery for up to 4.5 hours and offers floor-only, waterline-only, regular, smart and eco modes. You can start, stop and schedule it from the MaytronicsOne app, and its cartridge filtration is described as capturing both ultra-fine and larger debris. Intelligent scanning maps the pool, and the cleaner returns to the edge when it finishes. It is listed for pools up to 50 ft.

Those are the features the classic CC Plus listing does not state. The trade-off is the usual one for cordless: a battery to keep charged, and a different set of parts, so the CC Plus filters on this page do not apply to it.

What stands out

• Cordless, up to 4.5 hours per the listing
• Waterline, stairs and sun ledges cleaned
• Wi-Fi app with scheduling
• Returns to the pool edge for pickup

Trade-offs

• A battery to keep charged
• Does not use CC Plus parts

9

Best for a mid-size inground pool

Dolphin Proteus DX3

A fair alternative if your pool is 33 ft or less. The listing uses the same wall climbing, scrubbing brush and top-load filter wording as the CC Plus.

• $$$ Premium

Check price on Amazon

Buy it if

You have a mid-size inground pool and the extra length of the CC Plus is more than you need.

Skip it if

Your pool is longer than 33 ft, or you need Wi-Fi: the listing does not mention it.

The Proteus DX3 listing describes a corded robot with wall climbing, an active scrubbing brush, a top-load filter basket and a 2-hour plug-and-play clean. It is listed for inground pools up to 33 ft. The listing gives an item weight of about 14.8 lb and does not state Wi-Fi, waterline cleaning or steps.

Treat it as a sizing choice. When two robots list the same features, the deciding fact is the pool length each is rated for.

What stands out

• Same core features as the CC Plus, per the listings
• Plug-and-play, corded

Trade-offs

• Rated up to 33 ft only
• Wi-Fi and waterline not stated
