Differences Between Dolphin S300 vs Dolphin Active 30
Design Comparison
The Dolphin S300 and Dolphin Active 30 are both built with a durable, compact frame suitable for pools up to 50 feet. Each unit includes a 60-foot swivel cable that prevents tangling and provides smooth, unrestricted movement throughout the cleaning cycle. The lightweight design of the Active 30 at 18.5 pounds makes it easy to carry and deploy, while the slightly heavier S300 at 19.5 pounds adds a bit more stability during waterline cleaning.
Both units feature ergonomic top handles, a sleek exterior, and a quick water-release system to reduce effort when lifting the unit out of the pool. The top-load filter access on both models makes maintenance straightforward and convenient.
Winner: Tie
Both models offer excellent portability, robust construction, and user-friendly handling. There is no clear design advantage for either model.
Cleaning Performance Comparison
The Dolphin S300 holds a noticeable edge in this category. It delivers 4500 GPH of suction power compared to the 4000 GPH offered by the Active 30. That extra suction allows the S300 to pick up more fine particles and heavier debris in a single cycle. Both models feature dual active brushes that rotate at high speeds to dislodge dirt and algae from the pool floor, walls, and waterline.
The S300 also operates for 2.5 hours per cleaning session, giving it extended reach and deeper coverage, especially in larger or heavily used pools. The Active 30, with a 2-hour runtime, performs well but may require more frequent cycles for equivalent cleaning.
Both models include multi-layer filtration with interchangeable fine and ultra-fine filter cartridges. These systems effectively capture debris ranging from leaves to sand and pollen. The Dolphin S300 has a slightly larger filter basket, allowing it to run longer without needing to be emptied.
Winner: Dolphin S300
With greater suction power, longer runtime, and a larger filter basket, the S300 provides more efficient and powerful cleaning—especially for larger pools or those with more debris.
Feature Comparison
Both models offer intelligent pool scanning and top-loading filter access. However, the Dolphin S300 pulls ahead with its advanced features. It includes SmartNav 2.0 navigation technology, which intelligently maps the pool layout and adjusts its cleaning path for optimal coverage. The Active 30 uses CleverClean navigation, which also provides smart scanning but lacks the real-time adaptability of the S300.
The S300 is equipped with Wi-Fi and connects to the MyDolphin Plus mobile app. This enables remote control, scheduling, cycle status updates, and firmware updates directly from a smartphone. The Active 30 lacks any wireless connectivity and can only be operated manually through its power supply unit.
Winner: Dolphin S300
With Wi-Fi connectivity, mobile app control, and superior navigation intelligence, the S300 offers a significantly more advanced and automated cleaning experience.
