When it comes to efficient and hands-free pool maintenance, few robotic cleaners offer as much value as the Dolphin Active 20 vs Dolphin Explorer E20. Both models are produced by Maytronics, a brand known for delivering reliable, high-performance pool-cleaning technology. Designed for small to medium-sized in-ground pools, these robotic cleaners offer powerful scrubbing, smart navigation, and energy-efficient operation.
While they appear nearly identical in features and construction, important differences in availability, warranty handling, and subtle technical components set them apart. In this comprehensive comparison, we explore all essential aspects of the Dolphin Active 20 vs Dolphin Explorer E20 to help you make an informed decision for your pool maintenance needs.

Differences Between Dolphin Active 20 vs Dolphin Explorer E20
Build Quality and Design
Both the Dolphin Active 20 and Dolphin Explorer E20 are built on a rugged, compact chassis designed for residential use. Weighing 16.5 pounds, each model is highly portable and easy to lift thanks to a well-balanced handle on top. Their outer shells are made from high-durability, UV-resistant plastic that protects the internal components from chlorine, sun exposure, and wear from pool chemicals.
The design philosophy is centered around simplicity, mobility, and reliability. These units are intended for homeowners who want to drop the cleaner in, press a button, and retrieve it a couple of hours later to find a spotless pool. Visually, they differ in branding, but structurally and functionally, they offer identical construction quality.
Winner: Tie
With matching form factor, weight, and durability, both models deliver the same design and user-friendly operation.
Cleaning Coverage and Pool Compatibility
Both units are optimized for in-ground pools up to 33 feet in length and can clean both the pool floor and walls. Their wall-climbing ability is driven by efficient water propulsion and traction systems that allow them to scale vertical surfaces up to the waterline—but not beyond. Neither unit is capable of cleaning the actual waterline, which requires a model with specialized jets or an advanced climbing algorithm.
The scrubbing action on walls is strong enough to reduce biofilm and algae accumulation, minimizing the need for manual brushing. These robots are ideal for rectangular, oval, or freeform pools with gentle inclines.
Winner: Tie
Both robots are matched in terms of cleaning reach and pool compatibility, including effective wall-climbing functionality.
Each cleaner uses CleverClean™ Technology, an advanced algorithm by Maytronics that scans the pool layout and determines the most effective path. This smart navigation system ensures complete floor and wall coverage with minimal overlap or missed areas. It also allows the robot to avoid obstacles like ladders, main drains, or pool lights without getting stuck.
The result is a full-cycle clean that doesn’t waste time or energy. For most users, the pattern appears semi-random but is actually calculated to ensure high-efficiency performance.
Winner: Tie
Both units operate using the same intelligent navigation system and exhibit equal levels of accuracy in cleaning path coverage.
Scrubbing System and Performance
The Dolphin Active 20 and Explorer E20 both feature dual scrubbing brushes, located at the front and rear of the chassis. These active brushes spin independently of the robot’s movement, allowing them to aggressively scrub dirt, algae, and sediment from all pool surfaces.
This two-brush configuration is particularly useful on textured pool surfaces like gunite or aggregate finishes, where dirt tends to embed more deeply. Whether cleaning after a storm or doing routine maintenance, these brushes deliver consistent scrubbing performance across various pool surfaces.
Winner: Tie
Both models provide robust scrubbing with dual active brushes, ensuring deep cleaning and powerful debris agitation.
Filtration System and Debris Capture
Each unit includes a top-load filter cartridge, accessible by simply lifting the lid on the top of the robot. These filters are designed to capture everything from leaves and acorns to fine sand and dust particles. The units are compatible with fine and ultra-fine cartridges, which users can swap depending on their debris conditions.
The filter size is generous enough to handle a full cycle without needing to be emptied mid-session. Cleaning the cartridge is quick—just rinse with a garden hose, and it’s ready to use again.
Winner: Tie
With the same filter system and compatibility, both units deliver equal performance in debris containment and water clarity.
Cable Management and Reach
Both the Active 20 and the Explorer E20 are outfitted with a 50-foot non-swivel cable, long enough to cover their intended pool size. However, the absence of a swivel means the cable may occasionally tangle or coil during extended use or erratic movement, particularly in non-rectangular pools.
While this doesn’t typically interrupt cleaning performance, users may need to manually untwist the cable after several sessions to maintain smooth operation.
Winner: Tie
Both cleaners have the same cable design and are equally prone to tangling without a swivel feature.
Cycle Time and Energy Efficiency
The two robots complete their cleaning cycle in approximately 2 hours, balancing energy usage with thorough cleaning. Their low-voltage DC motors make them extremely energy-efficient, consuming far less power than traditional pool vacuums that rely on booster pumps or the pool’s main filtration system.
This plug-and-play functionality reduces energy bills and simplifies pool maintenance by operating independently of external plumbing or filtration lines.
Winner: Tie
Equal runtime and low-energy operation make both robots excellent choices for eco-conscious pool owners.
Control Panel and Automation Features
Both the Dolphin Active 20 and Explorer E20 use a single-button power supply, with no built-in display or control panel. There is no app control, no Bluetooth, and no weekly scheduler, which means users must start each cleaning cycle manually.
Although this minimalism appeals to those who prefer simplicity, it limits automation potential. Users seeking scheduled cleanings or smartphone integration would need to consider more advanced models like the Dolphin S300.
Winner: Tie
With identical control interfaces and lack of smart features, both models are evenly matched in terms of operational control.

Conclusion
Choose Dolphin Active 20 if you want a premium-grade robotic pool cleaner offered through select pool dealers, potentially backed by enhanced service support and exclusive promotions. It’s perfect for users who value solid cleaning power, proven performance, and the brand reliability that comes with Maytronics engineering.
Choose Dolphin Explorer E20 if you prefer a widely accessible unit with matching performance, ideal for in-ground pools up to 33 feet. It delivers the same cleaning results and technology in a slightly different retail package.
Overall Winner: Tie
Functionally identical in every key area—performance, navigation, scrubbing, and filtration—the Dolphin Active 20 and Dolphin Explorer E20 are two sides of the same coin. Choosing between them comes down to personal preference, dealer availability, and branding. Whichever model you select, you’ll be investing in one of the most capable robotic pool cleaners available in the mid-range market.
