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

Reliable and workhorse are the words owners attach to the CC Plus, usually in the same sentence as a recommendation. People who have owned one for several summers say it runs daily and asks for little.

The complaints are about ageing parts rather than cleaning. The cable is the big one: after a few years it stiffens, coils and tangles, and a new one is a real cost. The filter panels are the other — cleaning them means disassembly, which owners who have had a basket-style robot notice every time.

Buy it for a pool up to about 40 feet if you want a proven corded robot and are willing to maintain it. Several owners running it alongside a skimmer robot describe that pairing as the point where pool cleaning stopped being a chore.

What owners like

  • Owners call it a workhorse and mean it literally: one ran it through the debris left by a fire — boards, shingles, embers and ash — emptying it every few minutes at first, and it never stopped.
  • Long service lives come up repeatedly; owners replacing a Dolphin after around seven years often buy another.
  • It picks up fine sand and particles as well as leaves, and owners pair it with a surface skimmer for a pool that stays clean between swims.
  • When it does fail it is usually fixable: one owner revived a dead unit by taking the motors apart and cleaning them rather than spending on a new one.

Common complaints

  • The cable stiffens and tangles with age. Owners report it knotting on every run after a few years, and the fix is a new cable — around $160 for an aftermarket one, closer to $400 from Maytronics.
  • The two filter panels have to be taken apart and cleaned piece by piece, which owners who have used basket-style Dolphins call a deal-breaker compared with a single basket.
  • Late-life failures cluster in the traction motor and the power supply.
  • A few new owners report theirs spending a lot of its cycle at the waterline rather than on the floor.

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

How long does a Nautilus CC Plus last?

Owners commonly report several years of daily use, and some replaced theirs only after around seven. Cables, traction motors and power supplies are the parts that tend to go first, and all are replaceable.

My CC Plus cable keeps tangling — what fixes it?

After a few years the cable stiffens and coils. Owners fix it with a replacement cable; aftermarket ones cost around $160 and Maytronics' own more like $400. A working swivel slows the problem.

Is cleaning the filters a hassle?

It is the most common complaint. The CC Plus uses filter panels that come apart for cleaning rather than a single basket, and owners coming from basket-style robots find it tedious.

Can you leave it in the pool?

One owner leaves theirs in and runs it daily, cleaning it weekly, with no problems over three summers — while noting that Maytronics advises against it.
