Explained

Compare Features in Detail

NanoFilters™

Often overlooked, a NanoFilter™ can be the most important part of a pool robot. Without it, microscopic particulate — fine dust, pollen, and algae — passes right through the standard filters found on most robots. These ultra-fine filters trap that debris for a noticeably cleaner, healthier pool. On some models NanoFilters are included; on others (like the Escape and Cayman) they're an inexpensive optional add-on. Learn more ›

Optional Dolphin Escape optional upgrade

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. On models where it isn't standard (such as the Escape), the timer is available as an optional upgraded power supply.

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 Sigma is backed by a 3-year warranty, while the Dolphin Escape 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.
