Dolphin S50

  • Plug'n'Play - Just plug it in, drop into the pool, for a hassle free clean
  • Easy Access Filter - Top-load filter access for easy and convenient debris removal and cleaning
  • Super Scrub - Intense scrubbing-power of pool surfaces, providing thorough cleaning
  • Energy Saver - Reduces water, chemical, and energy usage with every pool cleaning
  • CleverClean - Smart scanning and advanced navigation for complete pool coverage

The Dolphin S50 is a compact and budget-friendly choice for above-ground pools up to 30 feet. It provides essential floor cleaning with a scrubbing brush and is simple to set up using the Plug'n'Play functionality. However, it does not offer waterline or wall cleaning and lacks a weekly timer, anti-tangle swivel, and smartphone app support. While it may be suitable for basic pool maintenance, more comprehensive models are available for users seeking a more thorough cleaning experience and enhanced features.
