Buy Dolphin QuantumDolphin Premium 3000 or Dolphin S100: our take
Dolphin Premium 3000 and Dolphin S100 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. Dolphin Premium 3000 is rated for pools up to 50 ft; Dolphin S100 is rated up to 33 ft. Dolphin Premium 3000 cleans floor, walls, and waterline; Dolphin S100 cleans floor and walls. Dolphin Premium 3000 lists 2 active brushes and CleverClean navigation. Dolphin S100 lists 1 active brush.
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
Dolphin Premium 3000 provides a weekly timer and smartphone control; Dolphin S100 provides a weekly timer and power-supply controls. Dolphin Premium 3000 uses continuous corded power, while Dolphin S100 uses a 50 ft corded cable. Dolphin Premium 3000 is listed at 17.9 lb versus 14 lb for Dolphin S100; that 3.8999999999999986 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Dolphin Premium 3000 is listed at $1,449 and Dolphin S100 at $849; Dolphin S100 is $600 less. Dolphin Premium 3000 lists a 3-year warranty compared with 2 years for Dolphin S100. Dolphin Premium 3000 and Dolphin S100 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.
