Dolphin Nautilus CC Supreme: what it gives up

  • 24.6 lb out of the water, with no auto-surfacing listed
  • Still only a one-year warranty at $1,349
  • 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

Dolphin S300: what it gives up

  • Only one fixed cycle length is listed
  • The Explorer E50 adds a filter-full indicator and three cycle lengths for less money
  • No micron figure, so its fine kit can't be set against the CC Plus's 70 µm
