Differences Between Dolphin Explorer E20 vs Dolphin S200
Design Comparison
The Dolphin Explorer E20 is purpose-built for in-ground pools up to 33 feet in length, delivering an ideal solution for medium-sized residential pools. Its compact frame weighs 16.5 pounds, and it features an ergonomic top handle for easy lifting and transport. The 50-foot cable is non-swivel, which can occasionally cause tangling during longer cycles. However, its lightweight chassis allows it to move effortlessly along pool floors and ascend pool walls for vertical cleaning.
The Dolphin S200 is a more advanced unit, designed to handle larger pools up to 50 feet. Though it shares the same 16.5-pound weight, it includes a 60-foot swivel cable, which helps prevent tangling during long sessions. Its chassis is reinforced to support aggressive vertical climbing, allowing the S200 to clean the floor, walls, and waterline—a zone the Explorer E20 does not reach.
Visually and structurally, the S200 offers a more premium feel, with a reinforced exterior shell, advanced drive system, and dual active brushes. It’s a more capable design overall, tailored for homeowners with complex pool shapes or larger cleaning zones.
Winner: Dolphin S200
The longer swivel cable, full pool coverage including the waterline, and enhanced frame quality make the S200 a superior choice in overall design and versatility.
Cleaning Performance Comparison
The Dolphin Explorer E20 offers robust floor and wall cleaning through its single active brush and 4,000 GPH suction. It handles sand, leaves, dirt, and algae with ease. The E20’s CleverClean™ Navigation system efficiently scans the pool layout to follow an optimized path, ensuring complete coverage within its 2-hour cleaning cycle. Its top-loading fine filter basket is effective at trapping small to mid-sized debris, though it lacks the fine particle separation seen in multi-layer systems.
The Dolphin S200, by contrast, uses dual active brushes—one at the front and one at the rear—which rotate at high speed to scrub stubborn grime more thoroughly. The PowerStream™ Mobility System enhances traction and stability, especially on vertical surfaces and tight corners, ensuring effective waterline scrubbing. It offers both standard and Eco modes, the latter being ideal for light daily maintenance. The multi-layer filtration basket separates large and ultra-fine debris in one cleaning cycle, making it ideal for pollen, fine dust, and algae spores.
In debris-rich environments or pools located near trees, the S200’s advanced scrubbing and superior filtration outperform the E20 consistently.
Winner: Dolphin S200
With dual active brushes, multi-surface cleaning including waterline, and multi-layer filtration, the S200 offers far more comprehensive and efficient cleaning performance.
Feature Comparison
The Dolphin Explorer E20 is designed with simplicity in mind. It includes CleverClean™ Navigation, enabling it to calculate efficient cleaning routes across floor and wall surfaces. Once connected to the power supply, the unit operates with a single push of a button—offering straightforward, dependable operation. However, it does not support programmable scheduling, smart cleaning modes, or any app-based interaction.
The Dolphin S200 goes further by incorporating PowerStream™ Mobility, which enhances grip and wall-climbing capability. This allows for better transition between pool surfaces and gives the robot a more adaptive cleaning route. Though it doesn’t include Wi-Fi or mobile app control, the S200’s cleaning intelligence feels more advanced thanks to its additional sensors and targeted wall coverage.
Both robots share the absence of app control and automation, but the S200’s Eco cleaning mode provides more flexibility in daily pool upkeep, helping users reduce energy consumption during light cleaning sessions.
Winner: Dolphin S200
Thanks to its additional cleaning modes and enhanced mobility system, the S200 offers more control and better adaptability even without Wi-Fi connectivity.
