Compare Features in Detail
Hands-Off Weekly Timer
An automatic pool cleaner should be automatic. A true weekly timer runs a complete pool-cleaning cycle on schedule — every day, every other day, or a few times a week — without you retrieving or recharging the robot between cycles. An app schedule on a cordless robot is not hands-off if the cleaner still has to be removed and recharged between cycles, so Poolbots does not count that as a true weekly timer.
Smartphone App Control
App connectivity can put scheduling, cycle selection and cleaner status on your phone, although the exact controls vary by model.
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. The Dolphin Oasis Z5i is backed by a 3-year warranty, while the Dolphin Liberty 200 carries a 2-year 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.
