The Dolphin Triton PS is a discontinued model that served inground pools up to 50 feet, with energy-efficient motors and waterline scrubbing functionality. While lightweight and easy to handle, it lacks a weekly timer, anti-tangle swivel, and smartphone app control. Although it covers essential cleaning, newer models with improved filtration and features may provide better performance and longevity, making the Triton PS less appealing for users needing high-end functionality.
