Buy Dolphin CaymanClear S or Niya Tracker 15: our take
Clear S 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
Clear S is intended for inground pools, while Niya Tracker 15 is intended for above-ground pools. Clear S is rated for pools up to 50 ft; Niya Tracker 15 is rated up to 20 ft. Clear S cleans floor, walls, and waterline; Niya Tracker 15 cleans floor. Clear S's documented cleaning system includes 2 active brushes, Intelligent navigation (C9 microprocessor), and Quad (2 pump + 2 drive) motors.
Filtration and debris
Clear S includes UltraFilter; Niya Tracker 15 includes Basket. That gives Clear S the clearer documented edge for fine silt, pollen and sand. Niya Tracker 15 has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Clear S provides a weekly timer, smartphone control, and included remote control; Niya Tracker 15 provides one-touch starts and power-supply controls. Clear S uses a 59 ft corded cable with an anti-tangle swivel, while Niya Tracker 15 uses cordless battery power. Clear S is listed at 27.6 lb versus 7.1 lb for Niya Tracker 15; that 20.5 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Clear S is listed at $1,749 and Niya Tracker 15 at $199; Niya Tracker 15 is $1,550 less. Clear S lists a 3-year warranty compared with 1 years for Niya Tracker 15. Clear S 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.
