Dolphin S2000 (99996291-US) at a glance
The S2000 is Maytronics' Wi-Fi corded Dolphin for pools up to 40 feet. It scrubs the floor, walls, waterline, steps and sun ledges, runs on a weekly timer you set in the MyDolphin Plus app, and uses an anti-tangle swivel on its cable. Because it plugs in, there's no battery to charge.

- Cycle: 2.5 hr default; choose 2, 2.5 or 3 hours
- Power: plug-in power supply; no battery, no charging

Our pairing pick: add a Betta SE Plus solar skimmer
Most of what ends up on your pool floor starts out floating: leaves, pollen, bugs and dust. The Betta SE Plus solar robotic skimmer patrols the surface all day on solar power and catches that debris before it sinks. With the surface handled, the S2000 has less to pick up, its filter fills more slowly, and you won't need to run it as often. The Betta has no cord, so there's nothing for the Dolphin's floating cable to tangle with.

Maytronics overview
Using it: what to expect
Corded robots like the S2000 don't have the charging limits of a cordless robot. You can run a cycle, rinse the filter and start another right away. A few things still matter:
| Situation | What to plan for |
|---|---|
| Normal weekly upkeep | Set the weekly timer in the MyDolphin Plus app and let it run on its own, or start cycles when you need them. The 2.5-hour default suits most pools; drop to 2 hours for light weeks or bump to 3 hours for heavy debris. |
| Spring opening / pool closed all winter | Net out the big leaves first and get the water clear. A winter's worth of debris fills the filter quickly, and a full filter cuts suction and climbing. Use the fine panels for heavy debris, rinse them between cycles, and run as many cycles as it takes. Because it's corded, you can run them back to back. |
| Fine dust, pollen, silt | Switch to the included ultra-fine panels once the heavy debris is gone. |
| Cable tangles | The swivel cuts down on twisting. Lay the cable out straight with no coils. If it does twist, unplug it and work the twists out starting at the robot end. |
| Getting it out | Lift it by the handle, never by the cable. Water drains out as you lift. |
| Where the power supply goes | Away from the pool edge, plugged straight into a GFCI outlet (no extension cord). Keep it out of direct sun and rain. |
| Storage | Rinse the filter, untangle and loosely coil the cable, and keep the robot out of direct sun between uses. Over a Minnesota winter, store the robot, cable and power supply indoors where they won't freeze. |
