What is the difference between AquaNaut 400 and 450? Applications. AquaNaut 400 is well suited for larger pools up to 20′ x 40′ or pools with deep ends. AquaNaut 450 cleans pools up to 20′ x 40′. In order for AquaNaut 450 to effectively clean a pool larger than 16′ x 32′ pool, it must be retrofitted by a pool professional with a larger cam (sold separately).
