Buy Dolphin CaymanDolphin Active 15 or Polaris 9300 Sport Pool Cleaner F9300: our take
Dolphin Active 15 and Polaris 9300 Sport Pool Cleaner F9300 are compared on pool fit, cleaning reach, debris handling, controls and ownership details. The recommendation is based on the job the robot must do—not a simple feature count.
Pool fit and cleaning reach
Dolphin Active 15 has a published maximum pool length of 33 ft; the other model does not have a verified length in our source material. Dolphin Active 15 cleans floor and walls; Polaris 9300 Sport Pool Cleaner F9300 cleans floor. Dolphin Active 15's documented cleaning system includes 1 active brush.
Filtration and debris
Dolphin Active 15 has documented included filtration—Basket and UltraFilter—while the other model's included media is not fully published. That gives Dolphin Active 15 the clearer documented edge for fine silt, pollen and sand. Dolphin Active 15 also has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Dolphin Active 15 provides a weekly timer and power-supply controls; Polaris 9300 Sport Pool Cleaner F9300 provides daily scheduling. Dolphin Active 15 uses a 40 ft corded cable, while Polaris 9300 Sport Pool Cleaner F9300 uses a 60 ft corded cable. Dolphin Active 15 is listed at 14 lb versus 18 lb for Polaris 9300 Sport Pool Cleaner F9300; that 4 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Dolphin Active 15 is listed at $849 and Polaris 9300 Sport Pool Cleaner F9300 at $1,393.60; Dolphin Active 15 is $544.60 less. Dolphin Active 15 and Polaris 9300 Sport Pool Cleaner F9300 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Cayman. Inground and above-ground pools up to 40 ft that need floor and wall cleaning.
