The Blue Pearl’s Aqua Smart guidance will clean the largest of pools five times more efficiently than conventional robotic cleaners. Targeting debris and problem areas to maximize efficiency, the Blue Pearl will save you time, maintenance, and electricity. Made of the highest quality parts including the industry’s best chemical and algae resistant Polyvinyl Alcohol (PVA) brushes, the Blue Pearl can clean any pool surface quickly and effectively.
