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 ›

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.

Warranty Coverage

A robot is only as good as its warranty. The Dolphin Nautilus EON 100 is backed by a 1-year warranty, while the Dolphin Cayman 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.
