Differences Between Dolphin Active 30 vs Dolphin Active 40
Design Comparison
The Dolphin Active 30 and Dolphin Active 40 are both designed with residential in-ground pools in mind, supporting up to 50 feet in length. Their outer shells feature rugged construction, top-mounted handles for easy lifting, and compact dimensions for maneuvering around steps and ladders. The Active 30 weighs 18.5 lbs, while the Active 40 comes in slightly heavier at 19 lbs, offering improved stability during wall and waterline scrubbing.
Both cleaners include a 60-foot swivel cable, which prevents tangling and ensures uninterrupted cleaning cycles, especially in large or uniquely shaped pools. The swivel design improves navigation and durability over time, particularly in daily or high-frequency use.
Visually, both models look nearly identical, with subtle branding variations. They also share the same top-loading access to the internal filter basket, which contributes to their easy-clean design.
Winner: Tie
Both models offer the same premium construction, swivel cable, and ergonomic design, making them equally convenient to handle and store.
Cleaning Performance Comparison
Both the Active 30 and Active 40 come equipped with dual active brushes that rotate at high speed to scrub pool floors, walls, and the waterline. These brushes are designed to loosen algae, scale, and fine sediment from all pool surfaces, including tile, concrete, fiberglass, and vinyl.
Each unit delivers 4000 gallons per hour (GPH) of suction power, enough to handle heavy debris loads and deliver clear water in a single cycle. Runtime is set at 2 hours, which is more than sufficient for cleaning most medium to large residential pools.
The Active 30 features a multi-layer filtration system, including both fine and ultra-fine filters, capturing everything from leaves to sand and pollen. The Active 40 includes the same filter system, with the added benefit of an extra filter basket that increases debris capacity. This upgrade reduces the need to clean the basket during or between cycles, which is particularly beneficial for pools surrounded by trees or subject to high debris levels.
Both units also offer waterline scrubbing, allowing them to clean all the way up to the pool’s edge—an area that often collects oil, grime, and buildup.
Winner: Dolphin Active 40
With the same powerful cleaning hardware but an extra filter basket for higher debris volume, the Active 40 offers more efficient maintenance with fewer interruptions.
Feature Comparison
The Dolphin Active 30 operates with a basic plug-and-play interface. Users simply press the button on the power supply to begin the cleaning cycle. It runs the preset 2-hour program and returns to its original position when finished. While easy to use, the Active 30 lacks programmability and remote access.
The Active 40 retains the same fundamental simplicity but adds smart control through the MyDolphin™ Plus mobile app. Via WiFi or Bluetooth, users can start, stop, schedule cleanings, and receive maintenance alerts directly from their smartphones. This makes pool maintenance more flexible and reduces the need for manual interaction with the power supply.
Both units use CleverClean™ navigation, a smart scanning algorithm that maps the pool to ensure full coverage while avoiding overlap. The navigation system is highly effective in standard pool layouts and performs well around ladders, drains, and corners.

With the addition of smart connectivity, scheduling, and remote management, the Active 40 provides a more modern and customizable user experience.
