Buy Dolphin QuantumDolphin Premium 2000 or Dolphin S2000: our take
Dolphin Premium 2000 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.
Pool fit and cleaning reach
Both robots are intended for inground and above-ground pools. Both are rated for pools up to 40 ft. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Dolphin Premium 2000's documented cleaning system includes 2 active brushes and CleverClean navigation.
Filtration and debris
Both models include Basket and UltraFilter. Both have documented fine-debris media, so basket capacity and ease of cleaning matter more than fine-particle capability.
Controls and day-to-day ownership
Both models provide a weekly timer and smartphone control. Both use continuous corded power. Both are listed at 17.9 lb, so lifting effort is effectively the same.
Price, warranty and the decision
Both are listed at $1,199. Each lists a 2-year manufacturer warranty. Dolphin Premium 2000 and Dolphin S2000 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Quantum. Inground pools up to 50 ft that need floor, wall and waterline cleaning, with fine debris.
