NanoFilters™

Often overlooked, a NanoFilter™ can be the most important part of a pool robot. Without it, microscopic particulate — fine dust, pollen, and algae — passes right through the standard filters found on most robots. These ultra-fine filters trap that debris for a noticeably cleaner, healthier pool. Learn more ›
