Dolphin M600 and Dolphin Wave 120 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 M600 is intended for inground pools, while Dolphin Wave 120 is intended for commercial pools. Dolphin M600 is rated for pools up to 50 ft; Dolphin Wave 120 is rated up to 121 ft. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Dolphin Wave 120's documented cleaning system includes Commercial-grade motors.
Filtration and debris
Dolphin M600 has documented included filtration—Basket and UltraFilter—while the other model's included media is not fully published. That gives Dolphin M600 the clearer documented edge for fine silt, pollen and sand. Dolphin M600 also has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Dolphin M600 provides a weekly timer, smartphone control, and included remote control; Dolphin Wave 120 provides no fully published timer, app or remote specification. Dolphin M600 uses a 60 ft corded cable with an anti-tangle swivel, while Dolphin Wave 120 uses continuous corded power.
Price, warranty and the decision
Dolphin M600 is listed at $1,999 and Dolphin Wave 120 at $7,899; Dolphin M600 is $5,900 less. Dolphin M600 lists a 3-year warranty compared with 2 years for Dolphin Wave 120. 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 100. Commercial pools up to 88 ft that need floor, wall and waterline cleaning.
