When looking for a high-performance robotic pool cleaner that combines efficiency, convenience, and deep cleaning capabilities, two models from Maytronics stand out in the mid-tier range: the Dolphin Explorer E20 vs Dolphin Explorer E30 WiFi. Both cleaners are designed for in-ground pools and offer powerful scrubbing, intelligent navigation, and hassle-free operation. However, subtle differences in smart features, wall-cleaning precision, and cable technology can significantly affect the overall user experience.
In this comprehensive comparison, we take a detailed look at both models to determine which offers the best value and performance for different types of pool owners.

Differences Between Dolphin Explorer E20 vs Dolphin Explorer E30
Below is a summary of the specifications:
Design Comparison
The Dolphin Explorer E20 is designed for in-ground pools up to 33 feet and features a rugged, compact build with a single front-mounted active brush. Weighing 16.5 pounds, it is manageable to carry and deploy, and it uses a 50-foot floating cable that provides adequate reach for smaller pool layouts. However, this model does not include a swivel mechanism, which can lead to occasional tangling during long cycles.
The Dolphin Explorer E30 WiFi, built for pools up to 50 feet, is slightly heavier at 17.8 pounds and includes a longer 60-foot swivel cable that helps prevent tangles, even during extended cleaning runs. The E30 WiFi features dual active brushes, one at the front and one at the rear, which work in tandem to provide more aggressive scrubbing and better grip, especially when transitioning from floor to wall.
Visually, both cleaners share Maytronics’ signature modern look and ergonomic top handles, but the E30 WiFi’s internal architecture is more robust, designed to accommodate deeper cleaning in larger pool environments.
Winner: Dolphin Explorer E30 WiFi
The longer swivel cable, larger pool compatibility, and dual-brush design make the E30 WiFi the superior option in terms of design flexibility and cleaning precision.

Cleaning Performance Comparison
The Explorer E20 delivers effective cleaning on the floor and partial walls, utilizing a single active brush to dislodge dirt, algae, and fine sediment. Its 4,000 GPH suction pulls debris into a top-loading filter basket, which is easy to remove and rinse. The E20 does not scrub the waterline but climbs high enough on most walls to reduce visible buildup and algae growth. Its 2-hour cleaning cycle is optimal for most medium-sized pools.
The Explorer E30 WiFi takes cleaning to another level with full coverage of floor, walls, and waterline. The dual active brushes provide deeper agitation, while its more powerful 4,500 GPH suction ensures that dirt and large debris are removed efficiently. The multi-layer top-load filter basket separates ultra-fine particles from larger debris, improving filtration quality and reducing the frequency of filter rinsing.
With more aggressive scrubbing, longer reach, and better suction, the E30 WiFi can maintain crystal-clear pool conditions even during peak swim season or in pools located near trees and dusty environments.
Winner: Dolphin Explorer E30 WiFi
Its ability to clean all surfaces—including the waterline—paired with stronger suction and dual brushes makes it the more thorough and effective performer.

Feature Comparison
The Dolphin Explorer E20 includes CleverClean™ Navigation, an internal algorithm that scans the pool’s shape and layout to calculate the most efficient pathing. It minimizes missed spots and reduces redundant cleaning. However, this model does not include any Wi-Fi capability or app-based scheduling. It operates on a plug-and-play system—once plugged in, it begins cleaning immediately and shuts off automatically after its cycle ends.
The Explorer E30 WiFi also uses CleverClean™, but adds intelligent scheduling and remote control via the MyDolphin™ Plus App. Through this app, users can:
- Start, pause, or stop the robot remotely
- Schedule cleanings by day and time
- Choose cleaning modes or cycle lengths
- Monitor system status and receive notifications
This added level of automation gives users more control, especially for those who want to manage their pool remotely or set recurring cleanings.
Winner: Dolphin Explorer E30 WiFi
Smart features like app scheduling and Wi-Fi control place the E30 WiFi far ahead in user convenience and customization.

Conclusion
Choose the Dolphin Explorer E20 if you own a smaller in-ground pool and prefer a simple, plug-in-and-go cleaner that handles floor and wall maintenance well. Its ease of use, compact size, and solid filtration make it an excellent entry point into the world of robotic pool cleaners for users who don’t need waterline scrubbing or smart control.
Choose the Dolphin Explorer E30 WiFi if you want deeper, more complete cleaning with the ability to control your robot remotely. With full pool coverage, better filtration, and the convenience of app-based scheduling, the E30 WiFi is the smarter and more powerful solution for medium to large in-ground pools.
Overall Winner: Dolphin Explorer E30 WiFi
With superior cleaning reach, dual brush power, smart connectivity, and a tangle-free swivel cable, the Dolphin Explorer E30 WiFi stands out as the most capable and future-ready choice for pool owners who want thorough, automated, and intelligent pool maintenance.
