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

  • Two-hour floor and wall cycle
  • Top-access fine filter
  • Single active scrubbing brush
  • Rated for in-ground and above-ground pools

What it does well

  • At 14.8 lb it is one of the lightest corded robots in the catalog, so lifting it out is not a two-hand job
  • Floor and walls in one fixed two-hour run, no programming
  • Filter opens from the top, so the debris never has to be tipped out upside down
  • Maytronics rates it for both in-ground and above-ground pools

What it gives up

  • Rated only to 33 ft, so a 16 × 36 or 20 × 40 in-ground pool is outside its rating
  • No swivel, so the cable will need untwisting over a season
  • One-year warranty, the shortest term Maytronics offers
  • No waterline pass and no scheduling of any kind

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

Reports on Maytronics' entry corded robot range from owners who say they would buy it again to owners whose unit failed early, one after four months and one on its first use.

When it runs, owners praise the cleaning. One says it does the pool in about two hours, another that it picks up 98% of a week of wind-blown debris, and one with the ultra-fine basket now backwashes monthly. Complaints center on lifespan and the cable, and one owner's pool technician puts any cleaner under $1,000 at three to four years at most.

Rated for pools up to 33 feet, in-ground or above-ground, it suits an owner who can do without an app, a timer or a waterline scrub. Two owners recommend adding a finer filter, and one with a beach entry says it sometimes drives straight out of the pool and across the deck.

What owners like

  • Quick on one owner's pool: almost a year in, it cleans the pool in about two hours, where a Polaris that owner had before took about six.
  • With the ultra-fine basket fitted, one owner says almost nothing reaches the pool filter now; the robot runs weekly, brushing is every other week and backwashing once a month (2023).
  • Two owners recommend a finer filter: one suggests the sand or fine filter, and one, still amazed after four years by the tiny bits it catches, calls the extra fine screens worth buying.
  • It saves time and money by owners' own counts: two say it has saved them hundreds of hours or countless hours, and one reckoned it breaks even against about six weeks of paying a pool company.

Common complaints

  • Units vary: several owners call theirs a tank, a workhorse or a beast, but one quit after four months and another's motor seized after two and a half seasons (2025), and one went back when its warped track fell off on first use (2026).
  • One owner's local pool technician says any cleaner under $1,000 lasts three to four years at most with good care, and that owner threw a Nautilus CC out after three years (2023).
  • The cable is a weak spot: one owner's twisted until the robot was confined to a ten-foot square of the deep end (2025), and two others had a CC stop working because of the cord, one fixed by fitting a new one (2026).

Questions owners ask about the Dolphin Nautilus CC

Which filter should I get for the Nautilus CC?

One owner recommends the sand or fine filter, and a four-year owner calls the extra fine screens worth buying. Another, with the ultra-fine basket fitted, says almost nothing reaches the pool filter now, so backwashing dropped to once a month (2023).

How long does it take to clean a pool?

Its cycle is two hours. One owner says it cleans the pool in about two hours, where a Polaris used before took about six; another runs it for two or three cycles at a time, three times a week.

How long does a Nautilus CC last?

Owner reports run from four months and two and a half seasons (2025) to one thrown out after three years and one still going after four (2023). One owner's pool technician puts any cleaner under $1,000 at three to four years at most with good care.
