Differences Dolphin Explorer E25 vs Dolphin Nautilus CC Plus
Below is a summary of the specifications:
Cleaning Coverage and Pool Compatibility
The Dolphin Explorer E25 WiFi is built for in-ground pools up to 40 feet in length. It offers complete floor and wall cleaning, powered by CleverClean navigation that scans the pool’s layout to ensure efficient route planning. While it performs well in smaller to medium-sized pools, its 50 ft standard cable limits its effectiveness in larger or more irregular pool shapes.
The Dolphin Nautilus CC Plus WiFi, designed for in-ground pools up to 50 feet, enhances its coverage with a 60 ft swivel cable and gyroscopic navigation. This allows for more accurate orientation detection and seamless directional changes, particularly when transitioning from the floor to the wall. It’s built to handle expansive pools with greater coverage needs and more complex contours.
Winner: Dolphin Nautilus CC Plus WiFi
With longer reach, enhanced navigation precision, and better handling in large or deep pools, the Nautilus CC Plus WiFi offers superior cleaning coverage.
Filtration System and Debris Management
The Explorer E25 WiFi uses a single fine filter basket, which provides effective filtration for standard debris like leaves, bugs, and dirt. The basket is top-loading for easy access, but it lacks a second ultra-fine layer, which may limit its ability to trap fine sediment such as sand, pollen, or silt without an aftermarket upgrade.
The Nautilus CC Plus WiFi includes a dual-layer filter system with fine and ultra-fine cartridges built-in. This allows it to separate coarse debris from microscopic particles more effectively, leading to better water clarity and less frequent filter maintenance. The filtration system is also top-loading for convenience.
Winner: Dolphin Nautilus CC Plus WiFi
Its superior dual-layer cartridge system ensures cleaner water, more efficient debris separation, and better long-term performance for pools with fine particulate matter.
Brush Performance and Scrubbing Action
The Explorer E25 WiFi is equipped with a single front-mounted active brush, which rotates faster than the unit’s movement to provide scrubbing pressure against the pool floor and walls. While effective for light to moderate algae or grime, its reach and surface contact are limited compared to dual-brush systems.
The Nautilus CC Plus WiFi features dual high-speed active brushes, delivering comprehensive contact across both the front and rear. These brushes scrub simultaneously, enabling it to dislodge stubborn dirt, algae, and scaling on pool floors and walls more thoroughly and efficiently.
Winner: Dolphin Nautilus CC Plus WiFi
The dual-brush system offers greater scrubbing surface, deeper cleaning strength, and better performance on slick or debris-heavy surfaces.

Both cleaners use CleverClean navigation, but the Explorer E25 WiFi employs a basic version with onboard sensors that map the pool layout and guide its cleaning pattern. It follows a logical path but may occasionally overlap or miss edges in pools with complex geometries.
The Nautilus CC Plus WiFi upgrades this with gyroscopic assistance, which enhances its directional stability and improves wall-to-floor transitions. This results in more consistent and accurate coverage, particularly in larger pools or ones with obstacles like ladders and tanning ledges.
Winner: Dolphin Nautilus CC Plus WiFi
Gyroscopic navigation delivers smoother operation and more precise cleaning paths for advanced pool layouts.
WiFi App Integration and Scheduling
Both the Explorer E25 WiFi and the Nautilus CC Plus WiFi feature full support for the MyDolphin Plus App, which allows pool owners to remotely start or stop cleaning cycles, set weekly schedules, and monitor system status from anywhere. This modern smart functionality gives users hands-free control and ensures that the pool remains clean without constant supervision.
Scheduling flexibility includes cleaning on specific days or at recurring intervals, making either cleaner ideal for vacation homes, rentals, or daily residential use.
Winner: Tie
Both models provide equal smart control through the MyDolphin Plus App, offering advanced convenience and automation.
Cable Design and Tangle Prevention
The Explorer E25 WiFi uses a standard 50 ft floating cable. While sufficient for smaller pools, the lack of a swivel mechanism increases the likelihood of cable tangling, especially during extended cleaning sessions with frequent turns or wall climbing.
The Nautilus CC Plus WiFi includes a 60 ft swivel cable, which actively prevents twisting and enables smoother rotation and directional changes. It reduces maintenance effort and keeps cleaning cycles uninterrupted.
Winner: Dolphin Nautilus CC Plus WiFi
The swivel cable extends reach and ensures tangle-free operation, particularly in longer or more complex pool designs.
Weight and Handling Ease
The Explorer E25 WiFi weighs just 13.8 lbs, making it one of the most lightweight models in Maytronics’ lineup. It’s easy to lift from the water, carry, and store, which is a major benefit for pool owners who prioritize portability or ease of handling.
The Nautilus CC Plus WiFi, while still manageable, is heavier at 19 lbs. The added weight is due to its dual filtration system, additional navigation hardware, and larger cleaning motor. It includes a sturdy top handle for secure lifting, but may feel bulkier to some users.
Winner: Dolphin Explorer E25 WiFi
Its lighter weight makes it more user-friendly for frequent manual handling and convenient storage.
Durability and Warranty Coverage
Both units are backed by a 2-year limited warranty, ensuring protection against manufacturing defects and premature wear. Maytronics is known for its high-quality construction, and both cleaners are built with robust materials suitable for extended exposure to pool chemicals, UV rays, and high-debris environments.
Internally, the Nautilus CC Plus WiFi features more powerful drive and cleaning systems, which are designed to withstand more demanding usage. However, the Explorer E25 WiFi offers dependable performance in more moderate cleaning conditions.
Winner: Tie
Both cleaners offer solid build quality and equivalent warranty coverage, ensuring dependable long-term use.
