Dolphin Nautilus CC Supreme

Three brushes, a 2.5-hour default cycle and both a fine and an ultra-fine filter kit in the box put the CC Supreme at the top of the Nautilus range. It is rated for in-ground pools to 50 feet and scrubs the waterline. The trade is weight: at 24.6 lb it is the heaviest Nautilus here.

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

  • Three brushes including a combined brush
  • 1.5 h and 2.5 h cycle options
  • Delay start and weekly timer
  • Waterline scrubbing
  • Two filter kits included

What it does well

  • Ships with both a fine and an ultra-fine filter kit, so the switch for a pollen week costs nothing extra
  • Three brushes where the rest of the Nautilus range has one or two
  • Delay-start and a choice of 1.5 or 2.5 hour cycles
  • Scrubs the waterline, a job the $749 CC Plus leaves to a hand brush

What it gives up

  • 24.6 lb out of the water, with no auto-surfacing listed
  • Still only a one-year warranty at $1,099
  • In-ground only, while the cheaper CC Pro is also rated for above-ground pools
  • Maytronics' micron claims for its ultra-fine kit disagree between pages, so no figure is shown here
  • No filter-full indicator, which the cheaper Explorer E50 has

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

Most owners who report on the CC Supreme are pleased with its cleaning. One says it paid for itself in saved time by its second season, another that it keeps the pool and tile sparkling, and owners in Phoenix and Florida praise its wall and waterline work.

The complaints are about the connected features, repairs and heavy debris. One owner's Wi-Fi and Bluetooth died within three years, and two others rate the app or manual drive poorly. One owner tired of repairs after four years, and two rate the Premier above it for leaves and debris, one returning the Supreme after a week. One owner also questions why the app schedules runs when the advice is to take the robot out.

Its catalog row puts it at the top of the Nautilus range, with three brushes and both fine and ultra-fine filter kits, and at 24.6 lb it is the heaviest Nautilus here. An owner in the dusty Southwest bought it for those filters, while one owner calls it overkill.

What owners like

  • On a pebble finish over gunite, one owner says it works perfectly and expects no marks, since its tracks and wheels are grey rubber, though that finish is not white.
  • The vacuuming holds up: one owner a little over three years in said in 2024 it still works great, another nearly three years in called its cleaning superb in 2025, and a third was in year three with no problems in 2026.
  • An owner in the dusty Southwest chose it for its fine filters and wall cleaning and is very happy with it.
  • Owners say it does the walls and waterline: a new owner in 2026 calls its waterline scrubbing great and its suction strong enough to run over piles of debris, and others say it cleans the floor, sides and waterline.

Common complaints

  • The connected features draw the complaints: one owner said in 2024 its Wi-Fi and Bluetooth had died within three years, leaving it button-start only, another finds manual drive nearly useless with a five to six second lag, and a third finds the app laughable.
  • One owner's lasted four years but needed multiple repairs, including two sets of brushes on each motor and a power supply, and in 2024 that owner shopped for something cheaper rather than keep repairing it.
  • One owner is puzzled that the app offers daily and weekly cleaning schedules when the usual advice is not to leave the robot in the pool between runs.
  • Stairs and shallow areas give it trouble: a new owner in 2025 had to keep driving it to the shallow end by the stairs before it rolled back to the deep end, and an owner in Phoenix says it struggles with stairs.
  • Two owners rate the Premier above it for heavy debris: one returned the Supreme after a week in 2026 for lacking the Premier's cleaning power, and another with lots of trees wishes for the Premier's large leaf bag, having to empty it often in early fall.

Questions owners ask about the Dolphin Nautilus CC Supreme

Is the CC Supreme safe on white plaster?

The only owner report is from a pebble finish over gunite, not white plaster: that owner says it works perfectly and expects no marks, since its tracks and wheels are grey rubber.

Should I leave it in the pool to use the scheduler?

Owners differ. One is puzzled that the app offers daily and weekly schedules when the usual advice is to take the robot out between runs, another leaves theirs in about 75 percent of the time and was in its third year without problems in 2026, and a third keeps an old pressure cleaner for winter so the Supreme need not stay in the pool.

What tends to fail?

One owner said in 2024 that the Wi-Fi and Bluetooth had died within three years. Another's needed multiple repairs over four years, including two sets of motor brushes and a power supply, and a third had an intermittent fault in the swivel connection two years in, with the warranty repair requiring the owner to pay to ship the whole robot.

Does the cable tangle?

Two owners say not so far: one says the fairly stiff cable has never tangled in nearly three years, and a new owner who coils it carefully had none in the first weeks. Another owner did get an intermittent fault in the swivel connection after two years.
