Niya Sonar Ray 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

Niya Sonar Ray has documented included filtration—Basket—while the other model's included media is not fully published. Niya Sonar Ray also has the better documented path for bulky leaves and larger debris.

Niya Sonar Ray is listed at 7.1 lb versus 18 lb for Polaris 9300 Sport Pool Cleaner F9300; that 10.9 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Niya Sonar Ray is listed at $199 and Polaris 9300 Sport Pool Cleaner F9300 at $1,393.60; Niya Sonar Ray is $1,194.60 less. Niya Sonar Ray 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.
