Explained
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 ›
Warranty Coverage
A robot is only as good as its warranty. Buying through an Authorized Dealer like Poolbots gets you the full manufacturer warranty — never pro-rated or limited by cleaning cycles — plus a 30-day in-pool trial with no restocking fees. Learn more ›
