Dolphin Nautilus CC Plus review: what owners and spec sheets show
Our verdict
The long-running corded choice. It never stops for a charge, owners report years of service, and Maytronics has replaced failed power supplies and cables under warranty. You give up an app, and you need a GFCI outlet about 12 feet back from the water.

Short answer: the Nautilus CC Plus is the robot to buy if leaves fall into your inground pool every day and you want a cleaner that runs as often as you like without charging. You give up an app, surface and waterline cleaning, and you get only a 1-year warranty; owners say the power supply and swivel cable are what fail.

It lists at $829 on maytronics.com, seen Oct 29, 2026 and shown in stock. That's about a third of the AquaSense 2 Ultra's price. Below: the specs that matter, what owners report over years of use, parts costs, fixes and how it fits a Florida pool.
How does the Nautilus CC Plus clean?
It's a plain corded robot. You drop it in, plug the power supply into a GFCI outlet, and it runs a fixed cycle across the floor and up the walls using Maytronics' CleverClean navigation and an active scrubbing brush. Maytronics' own page is inconsistent on cycle length: one line says about 2 hours, another says a full cycle takes 3. There's no app, no scheduling on this version and no surface skimming. The anti-tangle swivel lets the cable rotate so it doesn't coil up as the robot turns.
The filter loads from the top: lift it out, unsnap the bottom and rinse. Maytronics recommends cleaning it after every cycle. An ultra-fine filter kit comes in the box for pollen and fine dust days.

What owners report
The owner threads we read describe a durable, no-frills robot whose weak points are electrical, not mechanical.
- It lasts. Owners commonly report 3 to 6 years of service, with some longer. Maytronics doesn't publish a lifespan figure.
- Warranty claims get honored. Several owners say Maytronics replaced a failed power supply, cable or motor within the warranty.
- Power supplies and cables are the weak link. The most common failure is the power supply or the cable, often at the swivel. A thread about a 4-year-old unit that stopped is typical: out of warranty, the fix becomes a parts decision.
- Steps get skipped. Owners say it doesn't clean steps well, which matches a floor-and-wall robot.
- Leaves aren't a problem. Owners with leafy yards like that it can run daily, or twice a day, without a charging wait.
T3, reviewing a rival, called the Wi-Fi version of the CC Plus a no-frills cleaner that cleans very well. These are patterns from a handful of public threads, not a survey.
What does it cost to keep running?
After the 1-year warranty, you're paying for parts. Maytronics' US parts store listed these on Oct 29, 2026. Not every listing fits the CC Plus, so match the part number to your serial or ask Maytronics before ordering.
| Part | Maytronics US store price, seen Oct 29, 2026 |
|---|---|
| Cable with swivel, 2-wire, 17 m | $229.99 |
| Power supplies (by part number) | $209 to $399.99 |
| Fine debris filter panels, 4-pack | $109.99 |
| Grey drive tracks, 2-pack | $34.99 |
| Universal caddy | $109 |
A cable plus a power supply can cost more than half the robot's price. That's why owners of 4- and 5-year-old units often weigh a repair against a new robot. Our how long pool robots last guide covers that call.
Common problems and fixes
- Power supply lights up but the robot doesn't move: Maytronics' troubleshooting FAQ walks through checking the cable connection and the robot. Owners say a failed cable or motor is the usual cause.
- Cable twists anyway: lay the full cable out straight in the sun to relax it, and check that the swivel turns freely.
- Climbs poorly or slides: clean the filter, since a clogged filter cuts suction, and check the tracks and brushes for wear. See pool robot not climbing walls.
- Trips the GFCI: don't use an extension cord. Repeated trips usually point to a cable or power supply fault worth a warranty claim.
Is the Nautilus CC Plus good for a Florida pool?
It's a strong fit for open pools under oaks and palms, where daily leaf drop would run a cordless battery flat. Run it every day in spring and empty the filter each time. Under a screened lanai, swap in the included ultra-fine filter kit for pollen season; our lanai pollen guide explains why.
Salt pools are fine within Maytronics' 5,000 ppm limit, which most saltwater chlorinators sit well under; rinse it with tap water after each run. The 95°F upper water limit is worth knowing: shallow, sun-baked Florida pools can creep close to it in August, so run it in the morning. There's no battery to cook, but keep the power supply shaded and dry, at least 12 ft from the water.
