Dolphin Nautilus CC Plus Wi-Fi

The long-running CC Plus, now with Wi-Fi and the MyDolphin Plus app for weekly scheduling. Maytronics rates it for in-ground pools up to 40 feet and ships it with the ultra-fine filter it says catches debris down to 70 microns. It scrubs the floor and walls but not the waterline.

A specification not listed here is one Dolphin does not publish for this model. It is left blank rather than estimated or borrowed from a sibling.

Features

  • Wi-Fi control through MyDolphin Plus
  • Weekly timer
  • Anti-tangle swivel cable
  • Ultra-fine filter rated to 70 microns

What it does well

  • The ultra-fine filter in the box is rated to 70 microns, the only in-box micron figure Maytronics publishes for any Dolphin here
  • App scheduling means it can run on a weekly timer without anyone at the pool
  • Swivel on the cable cuts down on tangling
  • Top-loading filter, where the $2,499 Premier makes you turn the robot over to empty it
  • Maytronics rates it to 40 ft, seven more than the plain Nautilus CC

What it gives up

  • Walls and floor only; the waterline ring stays yours to brush
  • In-ground only by Maytronics' own classification
  • A one-year warranty on a robot at this price
  • At 20.8 lb it is six pounds heavier than the Nautilus CC

The two lists above come from the maker’s own specifications and this site’s arithmetic on them, not from owner reports. Where owner discussion has been read it appears in its own section below, so the two are never mistaken for each other.

What owners say

Owners who like the CC Plus talk about cleaning and staying power. One cleared fire debris with it, one who runs it beside a surface skimmer loves it for reliability and effectiveness, and others report three to six years of use, one now on a second unit.

The complaints are mostly about parts. Cables stiffen or fail at the swivel, power supplies give out, sometimes early, and tracks come loose on older units. Owners also report it getting stuck on ladders and stairs, and on the Wi-Fi version some have had the connection drop or the app lose the robot.

Maytronics rates it for in-ground pools up to 40 feet. Owners who keep one going replace cords and power supplies and clean out motors themselves, and one owner calls it among the best robots to work on, if one that needs the work. Two who tried cheaper cordless robots found them no match.

What owners like

  • One owner bought it after a fire took out the skimmer, and it cleared boards from a burned shed, shingles, embers and ash, needing emptying every 5 to 10 minutes at first but never faltering.
  • Owners report years of service: one is on a second CC Plus after the first lasted five or six years, one was in a fourth trouble-free year in 2023, and one reported six years in 2024 with only drain and track hang-ups.
  • Two owners who tried cheaper cordless robots rate it higher: one went back to a CC Plus in 2026 after a WYBOT C2 died in eight months, and another found a WYBOT B1 still left dirt after three floor-only runs.
  • Owners keep it running with their own repairs: one cleaned the metal dust out of the motors rather than pay about $800 for a new robot, and another revived a dead unit with a $150 aftermarket cable.
  • It is not sold as a waterline cleaner, yet owners say it climbs that far: one sees it scrub at the coping for a few seconds each time, and another says it gets the waterline, just not perfectly.

Common complaints

  • The cable wears out: one owner's went stiff and tangled every run after a few years, others failed or corroded at the swivel, owners priced replacements at $150 to $170 in 2026, and one saw the OEM cord at about $400 in 2025.
  • Owners describe two filters to empty rather than one basket: a former owner found taking all the pieces apart too much of a chore, and another did not know about the second, rear filter cage until it had packed with dirt over four years.
  • Power supplies fail, sometimes early: one owner's gave out at about 15 months, another's fried and was replaced under warranty, and one owner rebuilt a dead one with a $50 board in 2026 rather than pay $300 for Dolphin's.
  • One new owner in 2026 says theirs spends all its time at the waterline and is not pleased with it.
  • It gets stuck: owners name the ladder, the stairs and seats, and the steps, one says it high-centers on main drains, and another has had it flip over on a sun deck.
  • On the Wi-Fi version the connection is a weak spot: one owner's dropped out from about six months and needed resets, so it now runs off a smart plug, and the app told another its 2022 unit was unsupported when the network changed.

Questions owners ask about the Dolphin Nautilus CC Plus Wi-Fi

How long does a Nautilus CC Plus last?

Owner reports range widely. Two units quit within two years, at about 15 and 18 months, while others report three, four and six years, one first unit lasted five or six, and one owner has had theirs since 2015, though its tracks now keep coming off.

What fixes a tangling or failed cable?

Owners replace it. One whose cord had gone stiff and tangled on every run paid $160 for a new one, another fixed a dead unit with a $150 aftermarket cable, and one owner found off-brand cords disappointing and recommends the official part. One owner whose first unit had swivel trouble occasionally unplugs the cable from the power unit and stretches it out in the sun.

Is cleaning the filters a hassle?

Owners disagree. One calls the dual filters very easy to clean and another the cartridges easy to clean and reuse, while a former owner found taking all the pieces apart too much. One owner did not realize there was a second, rear filter cage until it had packed with dirt over four years.

Can you leave it in the pool?

Owners do, against Maytronics' advice. One leaves it in all the time, runs it daily and cleans it weekly, and was going into a third summer without a problem in 2025; another's lives in the pool apart from swims and had a power unit and a cable replaced under warranty in four years. One owner's stopped five days after it went in for good and needed a warranty repair.

Is the Wi-Fi worth paying for?

Owners who answered lean no. One called it just a timer with a weak connection even on strong home Wi-Fi, and owners of the non-Wi-Fi model do not miss it, one calling it not worth the extra cost or the reliability risk. Another found it useful only for remote starts and scheduling.
