Buy Dolphin EscapeDolphin Nautilus AG or Polaris 9300 Sport Pool Cleaner F9300: our take
Dolphin Nautilus AG 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 Nautilus AG has a published maximum pool length of 30 ft; the other model does not have a verified length in our source material. Each cleans floor, so coverage alone does not separate them. Dolphin Nautilus AG's documented cleaning system includes 1 active brush and CleverClean navigation.
Filtration and debris
Dolphin Nautilus AG has documented included filtration—Basket—while the other model's included media is not fully published. Dolphin Nautilus AG also has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Dolphin Nautilus AG provides one-touch starts and power-supply controls; Polaris 9300 Sport Pool Cleaner F9300 provides daily scheduling. Dolphin Nautilus AG uses continuous corded power, while Polaris 9300 Sport Pool Cleaner F9300 uses a 60 ft corded cable. Dolphin Nautilus AG is listed at 14.6 lb versus 18 lb for Polaris 9300 Sport Pool Cleaner F9300; that 3.4000000000000004 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Dolphin Nautilus AG is listed at $568 and Polaris 9300 Sport Pool Cleaner F9300 at $1,393.60; Dolphin Nautilus AG is $825.60 less. Dolphin Nautilus AG 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 Escape.
