Explained
An automatic pool cleaner should be automatic. A programmable weekly timer sets the robot to clean at different intervals — cleaning for you every day of the week without manually turning it on and off.
Say goodbye to tangled cords. An anti-tangle swivel lets the robot move 360° around your pool without the cord getting tangled, so you can sit back while it cleans. Learn more ›
