Why it matters

Dolphin Sigma vs Dolphin S200: how they compare

The Dolphin Sigma is part of the ProLine™ lineup — the most advanced Dolphin ever, with a gyroscope and app control. It cleans pools up to 50 ft with floor + walls + waterline coverage and NanoFilters™ filtration, backed by a 3-year warranty.

The Dolphin S200 is part of the S-Series™ lineup — a specialty-retailer model with a weekly timer and a 2-year warranty. It handles pools up to 50 ft with floor + walls + waterline coverage and Fine filter basket filtration, backed by a 2-year warranty.

Our verdict: the Dolphin Sigma wins

The Dolphin Sigma is our pick. As part of the ProLine™ — one of our two top-recommended lineups — it steps ahead of the Dolphin S200 with floor + walls + waterline coverage, NanoFilters™ filtration and a 3-year warranty.

The Dolphin S200 lists at a lower MSRP of $1189, but the step up to the Dolphin Sigma buys a meaningfully better clean and longer coverage that's well worth it.
