Buy Clear SDolphin Nautilus CC Supreme or Polaris 9300 Sport Pool Cleaner F9300: our take
Dolphin Nautilus CC Supreme 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 CC Supreme has a published maximum pool length of 50 ft; the other model does not have a verified length in our source material. Dolphin Nautilus CC Supreme cleans floor, walls, and waterline; Polaris 9300 Sport Pool Cleaner F9300 cleans floor. Dolphin Nautilus CC Supreme's documented cleaning system includes 2 active brushes and CleverClean navigation.
Filtration and debris
Dolphin Nautilus CC Supreme has documented included filtration—Standard filter and UltraFilter—while the other model's included media is not fully published. That gives Dolphin Nautilus CC Supreme the clearer documented edge for fine silt, pollen and sand.
Controls and day-to-day ownership
Dolphin Nautilus CC Supreme provides a weekly timer, smartphone control, and included remote control; Polaris 9300 Sport Pool Cleaner F9300 provides daily scheduling. Dolphin Nautilus CC Supreme uses a 60 ft corded cable with an anti-tangle swivel, while Polaris 9300 Sport Pool Cleaner F9300 uses a 60 ft corded cable.
Price, warranty and the decision
Dolphin Nautilus CC Supreme is listed at $1,599 and Polaris 9300 Sport Pool Cleaner F9300 at $1,393.60; Polaris 9300 Sport Pool Cleaner F9300 is $205.40 less.
