Buy Dolphin Wave 60Dolphin Nautilus Titan or Dolphin W20: our take
Dolphin Nautilus Titan and Dolphin W20 can be compared on specifications, but they are designed for different jobs. Start with residential versus commercial use, then use the details below to understand the tradeoffs.
Pool fit and cleaning reach
Dolphin Nautilus Titan is intended for inground pools, while Dolphin W20 is intended for commercial pools. Dolphin Nautilus Titan has a published maximum pool length of 50 ft; the other model does not have a verified length in our source material. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Dolphin Nautilus Titan lists 2 active brushes and CleverClean navigation. Dolphin W20 lists Commercial-grade motors.
Filtration and debris
Dolphin Nautilus Titan has documented included filtration—Basket and UltraFilter—while the other model's included media is not fully published. That gives Dolphin Nautilus Titan the clearer documented edge for fine silt, pollen and sand. Dolphin Nautilus Titan also has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Dolphin Nautilus Titan provides a weekly timer and smartphone control; Dolphin W20 provides no fully published timer, app or remote specification. Both use continuous corded power.
Price, warranty and the decision
Dolphin Nautilus Titan is listed at $1,599 and Dolphin W20 at $1,999; Dolphin Nautilus Titan is $400 less. Dolphin Nautilus Titan lists a 1-year warranty compared with 3 years for Dolphin W20. These robots are built for different jobs, so pool type and facility capacity decide the comparison before individual features do. For a residential pool, the Pool Express pick is Dolphin Quantum. Inground pools up to 50 ft that need floor, wall and waterline cleaning, with fine debris. For a commercial facility, the Pool Express pick is Dolphin Wave 60. Commercial pools up to 50 ft that need floor, wall and waterline cleaning.
