Differences Between Dolphin S200 vs Dolphin S300
Design Comparison
Both the Dolphin S200 and S300 are designed for in-ground pools up to 50 feet and feature a compact, lightweight chassis with an ergonomic handle for easy removal. Each includes a 60-foot floating cable, but only the S300 is equipped with an anti-tangle swivel, which significantly improves mobility in pools with steps or tight corners.
The S200 weighs approximately 16.5 pounds, making it slightly lighter and easier to carry than the 18.5-pound S300. Aesthetically, both units feature a clean and modern grey-blue design typical of the S-Series.
Winner: Dolphin S300
With its anti-tangle swivel and slightly more robust cable handling, the S300 is better suited for larger or irregular-shaped pools that require consistent movement and navigation.

Cleaning Performance Comparison
Both models use dual active scrubbing brushes that rotate at high speeds to dislodge stubborn debris, algae, and grime from the pool floor, walls, and waterline. They are equipped with the same 4000 GPH suction and complete a full cleaning cycle in about 2 hours.
The Dolphin S200 performs extremely well in standard residential pools with light to moderate debris. It climbs walls confidently and scrubs effectively at the waterline, capturing sand, silt, and leaves in its large top-loading filter basket.
The Dolphin S300, while using the same brush and suction system, delivers slightly more refined navigation. Its internal control system allows for improved cleaning patterns, and users can adjust settings through the app depending on pool conditions, such as post-storm cleanings or regular maintenance.
Winner: Dolphin S300
Both units clean exceptionally well, but the added control and refined cleaning behavior of the S300 give it a small advantage for users who want more customization.

Feature Comparison
The Dolphin S200 is equipped with a weekly scheduler built into the power supply, allowing users to schedule cleanings for every day, every other day, or every third day. It’s a highly reliable, set-it-and-forget-it system for users who prefer a hands-off experience without digital connectivity.
The Dolphin S300 enhances functionality by offering Bluetooth and Wi-Fi connectivity via the MyDolphin Plus app. Through the app, users can remotely schedule cleanings, start or stop the robot, and monitor cleaning status in real time. It also offers a Quick Clean mode, which runs a shorter cycle—ideal for light cleanups before guests arrive.
Winner: Dolphin S300
The S300’s app control, advanced scheduling, and smart cleaning modes provide significantly more convenience and adaptability.
