Buy Dolphin PremierDolphin Premier or Dolphin S2000: our take
Dolphin Premier and Dolphin S2000 are compared on pool fit, cleaning reach, debris handling, controls and ownership details. The recommendation is based on the job the robot must do—not a simple feature count.

Dolphin Premier is rated for pools up to 50 ft; Dolphin S2000 is rated up to 40 ft. Each cleans floor, walls, and waterline, so coverage alone does not separate them.

Filtration and debris
Dolphin Premier includes Standard filter, NanoFilters, Oversized leaf bag, and Multi-Media; Dolphin S2000 includes Basket and UltraFilter. Both have documented fine-debris media, so basket capacity and ease of cleaning matter more than fine-particle capability.
