The S-Series is the Dolphin range sold by specialty pool retailers, from the floor-only S50 to the app-connected S400 and the step-climbing S2000. Compare all six by pool size, coverage, filtration and controls, then see the Max-Series™ and ProLine™ robots we ship free.
The S50 cleans floors only, the S100 adds walls, and the S200, S300 and S400 scrub the floor, walls and waterline of pools up to 50 ft, with a timer, app and caddy arriving as you move up. The S2000 adds steps and sun ledges for pools up to 40 ft. Prices are Maytronics list prices.

Specialty pool retailers carry the S-Series instead of the models sold online, and the ladder is easy to read: each step up adds pool size, coverage or control. The S50 is a 14.6-lb floor cleaner for above-ground and small pools; the S100 climbs walls with a combine filter kit; the S200 reaches 50 ft and the waterline; the S300 adds the myDolphin™ Plus app and a caddy; and the S400 moves to a multi-layer basket with a full-filter indicator and selectable cycles.
Every model from the S100 up includes a weekly timer, and every one is a corded, plug-and-play Dolphin with a top-loading filter basket.
The S2000 is the latest shape in the line. It cleans the floor, walls, waterline, steps and sun ledges of pools up to 40 ft on 2, 2.5 or 3-hour cycles, pairs with the myDolphin™ Plus app and routes a tangle-free swivel cable. Interchangeable filtration lets you swap between the combine kit and the included ultra-fine kit.
Start with your pool length and the coverage you need, then choose the filtration and controls that fit your routine. For recommendations across every Dolphin family, read our guide to the best robotic pool cleaners →
The S50, S200 and S300 ship with a fine filter kit, the S100 and S2000 with a combine kit for leaves and fine dirt, and the S400 with a multi-layer basket. The S100 through S300 and the S2000 include an ultra-fine kit in the box; the S400 adds a full-filter indicator so you know when to rinse.

The S50 is plug and play. The S100 and S200 add a weekly timer on the power supply. The S300, S400 and S2000 connect to the myDolphin™ Plus app, and the S400 and S2000 add a delayed start and a choice of cycle lengths from your phone.
