Differences Between Dolphin Explorer E20 vs Dolphin Explorer E30
Below is a summary of the specifications:




Design Comparison
The Dolphin Explorer E20 is built for in-ground pools up to 33 feet. It comes with a 50-foot cable but lacks a swivel feature, which may cause some tangling during extended cycles in larger or irregularly shaped pools. The compact design and 16.5-pound weight make it easy to carry and store. Its build is tailored to floor and wall cleaning, using treads and an active brush system to climb vertical surfaces reliably.
The Dolphin Explorer E30 Wi-Fi enhances this design with a 60-foot swivel cable, allowing it to cover in-ground pools up to 40 feet without tangling. The anti-tangle swivel makes a noticeable difference in daily usability. The unit shares the same weight and overall profile as the E20 but adds slightly more robust climbing ability to support waterline scrubbing. This makes it more effective in handling complex pool surfaces, such as walls with waterline grime or textured tiles.
Winner: Dolphin Explorer E30 Wi-Fi
With a longer swivel cable and support for larger pools, the E30 Wi-Fi delivers better usability and extended range without compromising on maneuverability.

Cleaning Performance Comparison
The Dolphin Explorer E20 delivers effective floor and wall cleaning using an active PVC brush and a powerful 4000 GPH suction rate. The cleaner operates on a 2-hour cycle, effectively removing dirt, algae, and small debris. However, it does not clean the waterline, and its performance is limited to submerged surfaces.
The Dolphin Explorer E30 Wi-Fi takes performance further with dual active brushes, which provide more contact and better agitation, especially on vertical walls. The 4500 GPH suction rate increases debris pickup speed and volume. Most notably, the E30 supports full waterline scrubbing, making it more comprehensive in maintaining the visible surfaces of the pool. The improved filtration basket includes both fine and ultra-fine filters, ensuring better removal of pollen, sand, and microscopic debris.
Winner: Dolphin Explorer E30 Wi-Fi
Thanks to its dual brushes, higher suction rate, and ability to scrub the waterline, the E30 Wi-Fi offers significantly better cleaning results across the entire pool surface.

Feature Comparison
The Dolphin Explorer E20 is a manual-start cleaner using a basic internal cleaning algorithm. It doesn’t feature scheduling, Wi-Fi, or smart navigation. While it efficiently covers the floor and walls, it requires user input before every cycle, making it less convenient for busy homeowners.
The Dolphin Explorer E30 Wi-Fi is equipped with MyDolphin™ Plus App control via Wi-Fi, allowing users to start, stop, and schedule cleaning sessions from their smartphones. It also includes Smart Navigation technology, which scans the pool layout to determine an efficient cleaning route. The weekly scheduler can automate cleanings multiple times per week, reducing the need for manual activation.
Winner: Dolphin Explorer E30 Wi-Fi
With Wi-Fi control, smart navigation, and programmable scheduling, the E30 Wi-Fi delivers superior automation and ease of use.
