The in-depth review
The S2000 is the Dolphin for pools that other robots quietly ignore — the ones with steps and sun ledges. It's a dealer-line model built for full coverage, not just the open floor.
Coverage most robots skip
Beyond floor, walls, and waterline, the S2000 is designed to work steps and sun ledges, the shallow features where debris collects and most cleaners give up. Interchangeable ultra-fine filtration handles fine dust, a weekly timer runs it on schedule, and it's sold and serviced through the dealer network. Coverage is rated to about 40 feet.
The trade-offs
That 40-foot ceiling means it isn't the pick for the largest pools, there's no app, and it's corded. You're buying coverage and service, not connectivity.

Frequently asked questions
Is the Dolphin S2000 cordless or corded?
The Dolphin S2000 is corded — it runs on continuous mains power through a floating cable, so there is no battery to recharge between cycles.
What does the Dolphin S2000 clean?
The Dolphin S2000 is rated to clean the floor, walls, waterline, steps and sun ledges. That includes the waterline, where sunscreen and body oils build into a greasy ring. It is an underwater cleaner, so it does not skim floating debris off the surface.
What size pool is the Dolphin S2000 designed for?
It is rated for pools up to 40 feet. On a longer pool it covers less ground per cycle and can miss spots, so size up if your pool runs past that.
Does the Dolphin S2000 have app control?
No — the Dolphin S2000 runs from on-unit controls rather than a mobile app, though it does include a weekly timer.
What filtration does the Dolphin S2000 use?
It filters debris through an interchangeable and ultra-fine kit. Rinse it after each cycle so suction and pickup stay strong.
What warranty does the Dolphin S2000 come with?
It comes with a 3-year limited manufacturer warranty (confirm current terms at purchase).
