How big is a big pool?
A 20 × 40 ft rectangle is 800 sq ft; a 25 × 50 ft pool is 1,250 sq ft. Most residential pools sit well inside the 3,000+ sq ft ratings of the Beatbot and Aiper flagships. For length-rated robots, the Polaris 9550 Sport (60 ft) and the Dolphin Premier and Quantum (50 ft) have the longest ratings.
A larger rating also gives more margin for deep ends, steps and ledges. Measure yours with the pool measuring guide.
