The Dolphin S200 and Dolphin S400 are two premium robotic pool cleaners designed for in-ground pools. While they share a similar base structure, the S400 introduces smart connectivity and advanced automation that could make a difference for tech-focused users.
In this comprehensive comparison, we’ll evaluate both models across all essential performance categories to help you determine which one offers better value for your needs.

Differences Between Dolphin S200 vs Dolphin S400
Design Comparison
Both the Dolphin S200 and S400 are engineered for in-ground pools up to 50 feet in length. They each include a 60-foot floating cable, but only the S400 is equipped with an anti-tangle swivel, which significantly improves movement in pools with complex shapes or tight corners. The S200 lacks this, which may lead to occasional tangling during long cycles.
In terms of weight and portability, the S200 is lighter at 16.5 lbs, making it easier to lift from the pool, especially for users seeking a more manageable device. The S400 weighs 18.5 lbs, but offers a more robust build and stable movement, particularly when climbing vertical walls or cleaning the waterline.
Winner: Dolphin S400
With an anti-tangle swivel cable and a more stable design for full pool coverage, the S400 is better suited for larger or irregular-shaped pools.
Cleaning Performance Comparison
Both units are equipped with dual active brushes that rotate independently, providing strong agitation to scrub away algae, dirt, and biofilm. Each model performs floor, wall, and waterline scrubbing, making them suitable for comprehensive pool cleaning.
The suction rate is identical at 4000 GPH, ensuring powerful water circulation and debris collection. However, the S400 includes multiple cycle durations (1.5, 2, or 2.5 hours), allowing users to choose a quick clean or a more thorough session. The S200 has a fixed 2-hour cycle without custom cleaning modes.
For filtration, the S200 uses a dual-layer top-load basket that handles fine and ultra-fine debris effectively. The S400 upgrades this with a multi-layer fine + ultra-fine filter system, offering better separation and improved dirt retention for clearer water after each run.
Winner: Dolphin S400
With its customizable cleaning cycles and superior multi-layer filtration, the S400 provides more flexibility and better cleaning efficiency overall.
Feature Comparison
The Dolphin S200 includes a simple but effective weekly scheduler built directly into the power supply. It allows users to automate cleaning for daily, every other day, or every third day without external devices. However, it lacks any smart features, remote control, or mobile integration.
The Dolphin S400, by contrast, comes equipped with Wi-Fi and Bluetooth connectivity through the MyDolphin Plus app. This allows users to remotely start, stop, and schedule cleanings from their smartphone. It also offers Smart Mode navigation, which intelligently scans the pool to optimize the cleaning path, reducing overlap and improving coverage. The app includes live status updates, error alerts, and access to cycle modes that the S200 cannot provide.
Winner: Dolphin S400
The S400’s smart features, app integration, and intelligent navigation provide a superior user experience and greater customization options.
