The handle on my old manual pool vac finally snapped. Not broke—snapped, like a dry twig, right in my hands while I was trying to fish a leaf out of the deep end. Pool water up to my armpits, pollen count so high I could taste it, and I’m holding two pieces of broken plastic wondering if this is what my life has come to. So yeah, I started looking at robots.
First impressions: it’s a box that cleans
The Dolphin Nautilus CC Plus showed up in a box that was surprisingly light. I was expecting something that felt like a small appliance—you know, the heft that says “I cost $800”—but nope. It’s got that hollow, plastic-y feel that made me immediately suspicious. The kind of lightweight that makes you wonder if they skimped on something important, like the motor or the brain.
But then I flipped it over and saw the brushes. Two big scrubbers on the bottom, and they actually spin freely. Not that cheap, sticky plastic that catches on everything—these have actual bristles, like a miniature street sweeper for your pool floor. The tracks are rubber, chunky, with deep treads that look like they could climb a brick wall. I pressed a track with my thumb—good grip. This thing wasn’t going to slip off my pool’s weird, textured plaster.
For the record, my pool is a mess. 16x32 in-ground, gunite, with a deep end that drops to 8 feet, some corners that aren’t quite 90 degrees, and a main drain that sticks up like a speed bump. The previous “automatic” cleaner I tried (a pressure-side unit that shall remain nameless) spent more time tangled around the ladder than actually cleaning. That was a rental. This one I actually bought.
The “plug it in and pray” phase See Today’s Deal on Amazon
Instructions are basically: drop it in, plug in the power supply, hit the button. That’s it. There’s a control box that sits on the pool deck—waterproof, or at least water-resistant, with a single button that cycles through cleaning cycles. No app. No Bluetooth. No Wi-Fi. Just a button and a little LED that blinks at you.
I threw it in the water, and it sank immediately. Which, you know, I guess is what it’s supposed to do. But there’s something unsettling about watching an $800 piece of electronics just disappear under the surface. It hit the bottom with a soft thump, sat there for maybe three seconds like it was thinking about its life choices, and then started moving.
CleverClean is actually clever
The navigation system is called “CleverClean,” which sounds like a buzzword that a marketing team came up with after three rounds of coffee. But I’ll be damned if it doesn’t work. It doesn’t bounce around like a Roomba that’s had too much caffeine. It moves in a pattern—overlapping passes, not random zigzags. I watched it do a full lap around the perimeter of the deep end, then start making rows across the floor.
It got the corners. Not perfectly—nothing gets corners perfectly—but it got close enough that I wasn’t fishing stuff out with the pole afterward.
The wall climbing? That’s the part I didn’t believe. I’ve seen the videos. Every pool cleaner on Amazon shows you a little animation of a robot scooting up a wall like Spider-Man. But seeing it actually happen in my pool, with my gross, slightly algae-filmed walls? It just tilted upward at a 45-degree angle, didn’t slow down, and just kept going. The tracks bit into the plaster, and it climbed all the way to the waterline, stopped, and scrubbed. Then it turned, like a little aquatic Roomba, and went back down.
It did this for two hours.
The waterline thing is real
One of the things that sold me on the CC Plus over the base model (which I’ll talk about in a second because I almost bought it instead) is the waterline cleaning. The Nautilus CC—the one without the “Plus”—doesn’t do the waterline. The Plus does. And I’ll be honest, I didn’t think it would actually scrub the scum line off. I thought it would just kind of bump into it, splash some water, and call it a day.
Nope. The thing parks itself at the top, brushes rotating, and just… scrubs. It doesn’t do the whole perimeter in one go—it has to work its way around—but after the full cycle, that oily, sunscreen-and-bug-spray film that always collects at the waterline was gone. Completely. That alone saved me a ton of scrubbing with a sponge.
Let’s talk filters because they matter
The CC Plus comes with two large filter panels. They slide into the top of the unit, and you lift them out to clean them. Easy. No tools. Just pull the handle, lift, and hose them off.
Here’s the thing: the standard filters are fine for leaves, bugs, and the occasional acorn that falls in. But for fine debris—dust, pollen, the silt that blows in during a storm—they’re not great. The water just pushes through them, and the fine stuff gets recirculated. A lot of people buy the ultra-fine filters separately, and I’m one of them now. If you’re considering the CC Plus, factor in an extra $25 for the aftermarket fine filters. Seriously. Dolphin Nautilus CC Plus on Amazon does exactly what it says. But if you want crystal-clear water, get the fine filters. It’s one of those “why didn’t they include these in the box” things.
The cord is a thing
Everyone complains about the cord. It’s 60 feet long, which is great for my pool, but it wants to twist. The CC Plus has a “swivel” mechanism that’s supposed to reduce tangling. It does, sort of. It doesn’t turn into a pretzel like my old cleaner’s cord, but it does get loops and kinks that I have to straighten out after every few uses.
The key is to not leave it in the pool. Run the cycle, pull it out, straighten the cord. If you leave it floating around, the cord will coil itself into a mess that takes 20 minutes to untangle. I made that mistake once. Learned my lesson.
How it handles my pool’s quirks
My pool has a set of steps in the shallow end. Gradual steps, not sharp ones. The Dolphin climbs them, gets to the top, and then… just sits there. Its bumper sensor triggers, it tries to back up, and sometimes it takes a while to figure out that it can’t go any farther. It always backs out eventually, but there’s a solid 15-second window where I’m watching it, thinking, “Come on, buddy, you can do it.”
The main drain is a different story. The suction is strong enough that it doesn’t get stuck. It just drives right over it. That’s a big deal for me, because my old cleaner would park itself on the drain and stay there until I fished it out. This one? Doesn’t even slow down.
It’s rated for pools up to 50 feet. Mine is 32, so it has plenty of room.
The one that got away—Nautilus CC vs. CC Plus
If you’re looking at the Nautilus line, you’ll see the base model CC and the CC Plus. The CC is cheaper. It also doesn’t do the waterline, and it has a simpler filter system. I almost bought it. I’m glad I didn’t. The waterline cleaning alone is worth the extra hundred bucks. And the larger filter panels on the Plus are easier to clean.
If you’ve already read my review of the Dolphin Nautilus Titan, you know I’m a fan of the brand’s bigger units. The Titan is for larger pools—deeper, wider, more demanding. The CC Plus is its smaller sibling for pools like mine. It doesn’t have the same battery life or the advanced mapping, but it doesn’t need to. For 50-foot pools and under, it’s the right tool.
If you’re still shopping around, my guide to the best robotic pool cleaners for small inground pools covers the CC Plus and a few alternatives. I also tested the WYBOT C1 and the Aiper Scuba S1 alongside it, but honestly? The Dolphin just worked better on my plaster. YMMV.
The downsides See Today’s Deal on Amazon
I promised you honest downsides, so here they are.
The power supply gets hot. Not “oh it’s warm” hot—hot enough that I wouldn’t want to touch it for long. It sits in direct sun on my pool deck, and after two hours of running, the plastic casing is uncomfortably warm. I started putting a towel over it. That helps. But it’s a little worrying.
The filter cleaning is messy. There’s no way around it. You pull the filters out, and water—not clean water, but the water that was in the robot—drips everywhere. I do it on the pool deck, right next to the water, so I can just rinse it off with a hose. But if you’re carrying this thing inside to clean it, you’re going to track water through your house.
The cycle time is two hours. That’s a long time for a robot to swim around. But it does a thorough job. I’m not complaining—I’m just warning you that you can’t run it and expect a quick fix. You drop it in, walk away, and come back when it’s done.
The price. It’s $829. That’s not cheap. For comparison, the Polaris 9450 Sport is close in price but has a remote control and better navigation. The Zodiac MX6 is cheaper but it’s suction-side, so it uses your existing pump. Different category entirely. For a robotic cleaner that doesn’t need your pool’s plumbing, the CC Plus is in the middle of the pack—not the cheapest, not the most expensive. It’s the Goldilocks option.
Does it actually last?
That’s the question, right? The reviews are all over the place. Some people have had theirs for four years and it’s still running. Others say it died after 18 months. The common thread is maintenance. You can’t leave it in the pool 24/7. You can’t leave it plugged in after it’s done. You have to clean the filters after every run. If you do that, it seems to last.
I read a review from a guy who said his black streaks on the plaster after the first use. He had a brand new pool and the robot left marks on his steps and bench. That’s a horror story. I haven’t seen that on my older plaster, but it’s a risk with any tracked robot on new surfaces. The rubber can leave marks if the surface is soft. If you have new plaster, maybe wait a few months before using a robot.
If you grab one through the links here, I might get a small cut—costs you nothing extra and keeps the lights on. But if you’re worried about durability, I’d buy through Amazon for the return policy. The 30-day window is enough time to test it out and see if it’s going to destroy your pool.
I also want to mention the customer reviews I read about the Dolphin Proteus DX3, which is a similar unit at a lower price. Some people really like it, but the consensus seems to be that the Nautilus CC Plus is the more polished product.
The little things
The LED on the control box stays on for about 45 minutes after the unit finishes its cycle. It’s a tiny, dim blue light, but it glows in the dark. If your pool equipment is near a bedroom window, it’s annoying.
The power cable is thick and not particularly flexible. It’s got a permanent curve from being coiled in the box. Even after weeks of use, it hasn’t straightened out. It wants to coil.
The rubber tracks have a faint chemical smell. You don’t notice it unless you put your face right up to it, but it’s there. It fades after a week or two.
When it’s climbing the wall, the sound changes. The motor whirs differently, and you can hear the brushes scraping against the plaster. It’s not loud—you can barely hear it from the deck—but the tone shift is noticeable underwater if you’re in the pool. Don’t swim with this thing. It’s a robot, not a pool toy. But you can hear it working, and there’s something reassuring about that.
I was writing this review at my kitchen table, and the cat kept trying to sit on the keyboard. Classic.
Who actually needs this See Today’s Deal on Amazon
If you have a pool and you hate cleaning it, this is for you. If you have a pool and you’re paying someone $150 a month to clean it, this pays for itself in a year. If you have a pool and you’re tired of scrubbing the waterline, this does it for you.
If you have a small pool (under 50 feet), this is probably a better fit than the bigger units. It’s lighter, easier to handle, and cheaper. I’ve spent more than $829 on two manual cleaners, a pressure-side unit that didn’t work, and enough replacement hoses to circle the globe. This is an investment, but it’s a one-time investment if you take care of it.
I still have to do some manual cleaning. The corners don’t get everything. The steps need a quick brush once a week. But the bottom? Spotless. The waterline? Clean. The filter basket? Full of stuff I used to scoop out with a net.
The little pool robot lives next to my pump, tucked under a shelf. I pull it out, unwind the cord, drop it in, and hit the button. Two hours later, I pull it out, hose off the filters, and put it away. It’s a routine now. It’s not exciting. But my pool stays clean, and I don’t have to stand on my head with a pole to make it happen.
Anyway, I have to go clean the cat’s litter box. If that’s not a metaphor for pool ownership, I don’t know what is.
