The Dolphin Nautilus CC Plus is one of the best-selling robotic pool cleaners of all time. The Dolphin Premier is the best robotic pool cleaner I've ever tested. So what happens when you put them head to head?
Hey there, Pool Nerds. I'm Justin, your resident pool aficionado. I've spent years testing both of these robots, and while the Nautilus CC Plus is a solid mid-range cleaner, the Premier plays in a completely different league. With commercial-grade motors, Multi-Media filtration, a leaf bag, and a 3-year warranty, the Premier delivers a level of performance the CC Plus simply can't match.
Bottom Line: The Dolphin Premier is a commercial-grade ProLine robot with Multi-Media filtration, NanoFilters, a leaf bag, waterline cleaning, and a 3-year warranty. The Nautilus CC Plus has none of these features.
But is the Premier worth the price difference? Let's compare them across every category that matters: pool coverage, filtration, suction power, navigation, automation, and warranty.

The specs already paint a clear picture, but the real-world differences are even more dramatic. Let's break it down.
Pool Coverage: Complete Clean vs Partial Clean
Both of these robots clean the floor and walls of your pool with dual scrubbing brushes. The Nautilus CC Plus does a solid job on these surfaces — I won't take that away from it. But it stops at the walls. It cannot clean the waterline.
Do you know what pool pros call the waterline? The scum line. It's where algae, bacteria, biofilm, sunscreen, body oils, and stuck-on debris all accumulate. It's arguably the dirtiest part of your pool. If your robot can't clean it, you're still scrubbing by hand — which defeats the purpose of owning a robotic pool cleaner.
The Dolphin Premier is the king of the waterline. It climbs all the way to the top of the pool and moves horizontally along the waterline, scrubbing away everything in its path. The HyperGrip tracks keep it locked in place while the dual HyperBrushes attack the scum line with authority.
After just a couple of cleaning sessions with the Premier, the waterline in my pool was spotless. No more dull buildup, no more residue clinging to the tile. Meanwhile, the CC Plus left the waterline untouched every single time.
At the Nautilus CC Plus's price point, I expect complete pool coverage. Missing the waterline is a major oversight, and it's the single biggest reason I recommend upgrading.
Winner: Dolphin Premier
Filtration: One Filter vs Multi-Media — It's Not Even Close
If pool coverage is the Premier's biggest advantage, filtration is a close second. This is where the gap between these two robots becomes a canyon.
The Nautilus CC Plus comes with one set of standard mesh filter cartridges. They handle leaves and larger debris reasonably well, but fine particles like pollen, dust, and microscopic algae pass right through. There's no option to upgrade, no alternative media — it's a one-size-fits-all approach.
The Dolphin Premier comes with Multi-Media — and it's a game-changer. Out of the box, the Premier includes three filtration options:
- Standard fine filters for everyday cleaning
- NanoFilters for ultra-fine particles and cloudy water
- Oversized leaf bag for heavy debris and leaves
Plus, there's an optional 4th media: a disposable debris bag for the dirtiest pools where you just want to toss the bag and be done with it.
The Premier is the only Dolphin robot with a leaf bag. If you have trees around your pool, this is enormous. Instead of the filter clogging up with leaves after one cycle, the oversized leaf bag holds a massive amount of debris. I tested it after a windy Texas storm, and the Premier's leaf bag was packed — but it handled everything without breaking a sweat.
Then there are the NanoFilters. These Gen-2 pleated polyester filters capture particles so fine you probably didn't even realize they were in your pool. After using them, I could actually see a difference in water clarity — that perfect, crystal-clear sparkle that makes your pool look like a resort. The CC Plus's mesh filters simply can't compete with this level of filtration.
Swapping between filter types is easy too — just pop one out and drop another in. It takes seconds. Having the flexibility to choose the right filter for the job makes the Premier feel less like a pool cleaner and more like a smart, adaptable cleaning assistant.
Winner: Dolphin Premier (by a wide margin)
Suction Power: Commercial-Grade vs Standard
The Nautilus CC Plus has decent suction at approximately 3,600 GPH (gallons per hour). For a mid-range robot, it gets the job done on standard debris.
The Dolphin Premier crushes it with 4,500+ GPH — nearly three times more suction than many competitors and roughly 25% more than the CC Plus. These aren't standard motors either. The Premier runs on dual commercial-grade motors — the same platform found in $2,000+ commercial Dolphin units like the Wave 75.
That extra suction translates directly to cleaning performance. In my testing, the Premier aggressively pulled in debris that the CC Plus would sometimes push around or miss on the first pass. Whether it was large leaves, fine dirt, or stubborn algae stuck to the floor, the Premier didn't flinch.
The commercial-grade motors also maintain consistent suction power throughout the entire cleaning cycle. There's no drop-off, no fading. Because both robots are corded, you don't get battery degradation — but the Premier's more powerful motors deliver a noticeably deeper clean.
Reports online show Dolphin Premiers lasting over 10 years and still running strong. While the model has evolved over the years — with additions like NanoFilters, Multi-Media, and upgraded SmartNav 2.0 — it's a testament to the build quality you get with commercial-grade components.
Winner: Dolphin Premier
Navigation & Scrubbing: Both Solid, But the Premier Covers More Ground
Both robots use Maytronics' SmartNav 2.0 navigation system, which scans and maps your pool for the most efficient cleaning path. Neither robot bounces around randomly — they both systematically cover the floor and walls.
The Nautilus CC Plus navigates floors and walls well. Its track-based traction system keeps it gripped to the pool surface, and I've always appreciated how reliably it covers the floor. The dual scrubbing brushes do a good job loosening standard debris.
But the Premier takes scrubbing to a different level. Its dual HyperBrushes are faster and more aggressive, and combined with the HyperGrip tracks, the Premier maintains rock-solid contact with every surface — including vertical walls and the slippery waterline area.
I noticed during testing that even on areas with slight algae buildup, where other robots might slip, the Premier didn't flinch. It's like giving your pool cleaner hiking boots instead of flip-flops — better traction means better cleaning.
And because the Premier can reach the waterline, its SmartNav 2.0 actually covers more of your pool. The CC Plus is limited by its inability to reach the waterline, so even with great navigation, it leaves a portion of your pool untouched.
Winner: Dolphin Premier
Weekly Timer & Automation: True Automation vs App-Dependent Scheduling
I've said it before and I'll say it again — a Weekly Smart Timer is a must-have feature on a robotic pool cleaner. It completely automates your pool cleaning routine. Set it once, and the robot handles everything on its own, every single day.
The Dolphin Premier includes a built-in Weekly Smart Timer right on the power supply. Pick your schedule — every 24, 48, or 72 hours — and the Premier automatically starts its cleaning cycle. No phone needed, no app required, no connectivity issues to worry about. Just reliable, hands-off automation.
I found the timer especially useful during the busy summer months when the pool saw heavy use. I'd set it to run early in the morning before anyone got in, and by the time the day started, the pool was already crystal clear. With the weekly timer and the Premier's corded design, I only had to pull it out once a week to empty the filter. That's true set-it-and-forget-it convenience.
The Nautilus CC Plus offers Wi-Fi scheduling through the MyDolphin Plus app. It works, but it's limited. The app only lets you schedule cleanings — you can't manually control the robot, choose different cycle lengths, or change settings while it's cleaning. And the power supply itself has been stripped down to just a simple on button, forcing you to rely entirely on the app for scheduling.
If app connectivity is important to you, I'd honestly recommend the Dolphin Sigma instead. It has a full-featured app with manual control, a gyroscope for advanced navigation, and NanoFilters — all for just a bit more than the CC Plus.
Winner: Dolphin Premier
Warranty: The Premier Wins by 6 Months — and Then Some
The Dolphin Premier comes with a 3-year warranty — 50% longer than the industry standard and a full 6 months longer than the Nautilus CC Plus's 2.5-year warranty. That could mean an extra pool season of coverage, potentially saving you several hundred dollars in repairs.
A longer warranty also says something about the manufacturer's confidence in the product. Maytronics clearly expects the Premier to last, and my experience backs that up — our test Premier has been running strong for over three years without a single hiccup.
There's another important factor here: restocking fees. Many sellers of the Nautilus CC Plus charge restocking fees of 20% or more if you return it. That means even if you never open the box, you could be out several hundred dollars. With the Premier through authorized dealers, that's typically not an issue. Always check the fine print before you buy — especially on Amazon.
Winner: Dolphin Premier
Final Verdict: The Premier Is the Better Robot in Every Way
So what's my final verdict on the Dolphin Nautilus CC Plus vs the Dolphin Premier?
The Dolphin Premier wins — with a clean sweep.
Here's the final scorecard:
| Category | Winner |
|---|---|
| Pool Coverage | Premier |
| Filtration | Premier |
| Suction Power | Premier |
| Navigation & Scrubbing | Premier |
| Automation | Premier |
| Warranty | Premier |
| Overall | Dolphin Premier |
The Nautilus CC Plus isn't a bad robot — it's been one of the most popular Dolphin cleaners for years. But when you stack it up against the Premier, it's clear that the CC Plus is showing its age. No waterline cleaning, no NanoFilters, no Multi-Media, no leaf bag, weaker motors, and a shorter warranty. At its current price point, the CC Plus simply doesn't deliver enough to justify the cost when better options exist.
The Dolphin Premier, on the other hand, is a commercial-grade cleaning machine disguised as a consumer product. It cleans your entire pool — floor, walls, and waterline — with the most powerful motors and the most versatile filtration system I've ever tested. The Multi-Media system with NanoFilters, a leaf bag, and a 3-year warranty make it the best robotic pool cleaner on the market.
If you want the absolute best? The Dolphin Premier is the robot to beat. Commercial-grade dual motors, the Multi-Media filtration system with NanoFilters and a leaf bag, waterline cleaning, and a 3-year warranty. It dominates the CC Plus in every category — and it's worth every penny.
If the Premier is outside your budget, the Dolphin Quantum gives you a ProLine experience at a lower price. You still get NanoFilters, the XXL MaxBin for massive debris capacity, dual HyperBrush motors, and the weekly timer for hands-off automation. It's the sweet spot between the CC Plus and the Premier.
For an even more affordable option, the Dolphin Cayman still outperforms the CC Plus — it's cheaper, includes wall climbing and a weekly timer, and can be upgraded with NanoFilters. If you're on a tight budget, the Cayman is the smarter buy.
