It handles pools up to 50 ft with floor + walls + waterline + steps coverage and Multi-layer top-load cartridge filtration, backed by a 1-year warranty.
Our verdict: the Dolphin Premier wins
The Dolphin Premier is our pick. As part of the ProLine™ — one of our two top-recommended lineups — it steps ahead of the Dolphin Nautilus EON 120D with floor + walls + waterline coverage, MultiMedia™ + NanoFilters™ filtration and a 3-year warranty.
The Dolphin Nautilus EON 120D is the cheaper option at $1199, but the step up to the Dolphin Premier buys a meaningfully better clean and longer coverage that's well worth it.
