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 Cayman optional upgrade

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.

Smartphone App Control

App connectivity can put scheduling, cycle selection and cleaner status on your phone, although the exact controls vary by model. The current Dolphin Quantum includes myDolphin Plus app connectivity with its programmable weekly timer.

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 ›
