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.
Full Filter Indicator
Know exactly when it's time to clean. The power supply alerts you directly when the filter is full — no need to pull out the unit to check.
Dual Stabilizer
Essential for waterline cleaning, dual stabilizers let the unit cling to the walls for a more precise, deeper clean at the waterline — with increased agility and an easy pickup handle.
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 W20 is backed by a 3-year warranty, while the Dolphin Odyssey 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.
