Compare Features in Detail

Programmable Weekly Timer

An automatic pool cleaner should be automatic. A programmable weekly timer sets the robot to clean on a schedule — every day, every other day, or a few times a week — without you turning it on and off.

Anti-Tangle Cable Swivel

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 ›
