Buy Dolphin PremierDolphin Active 20 or Dolphin Premier: our take
Dolphin Active 20 and Dolphin Premier 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 pools. Both are rated for pools up to 50 ft. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Dolphin Active 20 lists 1 active brush. Dolphin Premier lists 2 active brushes, SmartNav 2.0 navigation, and Dual commercial-grade motors.
Filtration and debris
Dolphin Active 20 includes Basket and UltraFilter; Dolphin Premier includes Standard filter, NanoFilters, Oversized leaf bag, and Multi-Media. 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 Active 20 provides a weekly timer and power-supply controls; Dolphin Premier provides a weekly timer, power-supply controls, and optional remote control. Both use a 60 ft corded cable with an anti-tangle swivel.
Price, warranty and the decision

Pool Express pick: Dolphin Premier. Dolphin Premier adds swappable Multi-Media filtration and an oversized leaf bag for changing debris. Dolphin Premier uses 2 active brushes instead of 1.
