Dolphin S2000 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 S2000 is intended for inground and above-ground pools, while Dolphin Wave 120 is intended for commercial pools. Dolphin S2000 is rated for pools up to 40 ft; Dolphin Wave 120 is rated up to 121 ft. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Dolphin S2000 lists 2 active brushes and CleverClean navigation. Dolphin Wave 120 lists Commercial-grade motors.
Filtration and debris
Dolphin S2000 has documented included filtration—Basket and UltraFilter—while the other model's included media is not fully published. That gives Dolphin S2000 the clearer documented edge for fine silt, pollen and sand. Dolphin S2000 also has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Dolphin S2000 provides a weekly timer and smartphone control; Dolphin Wave 120 provides no fully published timer, app or remote specification. Both use continuous corded power.
Price, warranty and the decision
Dolphin S2000 is listed at $1,199 and Dolphin Wave 120 at $7,899; Dolphin S2000 is $6,700 less. Each lists a 2-year manufacturer warranty. 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.
