Buy Dolphin CaymanDolphin Quantum or Niya Tracker 15: our take
Dolphin Quantum and Niya Tracker 15 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 Quantum is intended for inground pools, while Niya Tracker 15 is intended for above-ground pools. Dolphin Quantum is rated for pools up to 50 ft; Niya Tracker 15 is rated up to 20 ft. Dolphin Quantum cleans floor, walls, and waterline; Niya Tracker 15 cleans floor. Dolphin Quantum's documented cleaning system includes 2 active brushes, SmartNav 2.0 navigation, and Dual DC motors.
Filtration and debris
Dolphin Quantum includes XXL MaxBin and NanoFilters; Niya Tracker 15 includes Basket. That gives Dolphin Quantum the clearer documented edge for fine silt, pollen and sand.
Controls and day-to-day ownership
Dolphin Quantum provides a weekly timer, smartphone control, and included remote control; Niya Tracker 15 provides one-touch starts and power-supply controls. Dolphin Quantum uses a 60 ft corded cable with an anti-tangle swivel, while Niya Tracker 15 uses cordless battery power. Dolphin Quantum is listed at 18.3 lb versus 7.1 lb for Niya Tracker 15; that 11.200000000000001 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Dolphin Quantum is listed at $1,649 and Niya Tracker 15 at $199; Niya Tracker 15 is $1,450 less. Dolphin Quantum lists a 2-year warranty compared with 1 years for Niya Tracker 15. Dolphin Quantum and Niya Tracker 15 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.
