Buy Dolphin CaymanDolphin Premier or Niya Tracker 25: our take
Dolphin Premier and Niya Tracker 25 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
Dolphin Premier is intended for inground pools, while Niya Tracker 25 is intended for above-ground pools. Dolphin Premier is rated for pools up to 50 ft; Niya Tracker 25 is rated up to 26 ft. Dolphin Premier cleans floor, walls, and waterline; Niya Tracker 25 cleans floor. Dolphin Premier lists 2 active brushes, SmartNav 2.0 navigation, and Dual commercial-grade motors. Niya Tracker 25 lists Sonar navigation and Brushless motors.
Filtration and debris
Dolphin Premier includes Standard filter, NanoFilters, Oversized leaf bag, and Multi-Media; Niya Tracker 25 includes Basket. That gives Dolphin Premier the clearer documented edge for fine silt, pollen and sand.
Controls and day-to-day ownership
Dolphin Premier provides a weekly timer, power-supply controls, and optional remote control; Niya Tracker 25 provides one-touch starts and power-supply controls. Dolphin Premier uses a 60 ft corded cable with an anti-tangle swivel, while Niya Tracker 25 uses cordless battery power. Dolphin Premier is listed at 20.3 lb versus 10 lb for Niya Tracker 25; that 10.3 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Dolphin Premier is listed at $1,999 and Niya Tracker 25 at $379; Niya Tracker 25 is $1,620 less. Dolphin Premier lists a 3-year warranty compared with 1.5 years for Niya Tracker 25. Dolphin Premier and Niya Tracker 25 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Cayman. Inground and above-ground pools up to 40 ft that need floor and wall cleaning.
