Dolphin Nautilus Titan: what it gives up

  • $1,599 with a one-year warranty is the costliest warranty-year among the Nautilus models
  • 22.6 lb, about five pounds more than the CC Pro
  • No cycle options beyond the two-hour default are listed
  • In-ground only; the CC Pro and Explorer E50 are rated for above-ground pools as well

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
