Buying guidance

Dolphin T25 or Dolphin Wave 300 XL: our take

Dolphin T25 and Dolphin Wave 300 XL 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 T25 is intended for inground and above-ground pools, while Dolphin Wave 300 XL is intended for commercial pools.

Dolphin Wave 300 XL lists 6 active brushes.

Filtration and debris

Dolphin T25 includes Basket and UltraFilter; Dolphin Wave 300 XL includes Basket. That gives Dolphin T25 the clearer documented edge for fine silt, pollen and sand.

Controls and day-to-day ownership

Dolphin T25 provides a weekly timer and power-supply controls; Dolphin Wave 300 XL provides one-touch starts and included remote control. Dolphin T25 uses a 50 ft corded cable, while Dolphin Wave 300 XL uses a 165 ft corded cable with an anti-tangle swivel. Dolphin T25 is listed at 15 lb versus 58.4 lb for Dolphin Wave 300 XL; that 43.4 lb difference matters when lifting the robot from the pool.
