Dolphin Explorer E70: Best Premium Wi-Fi Cleaner with 3-Year Warranty Under $800
The Ultimate Choice for Large In-Ground Pool Owners
Tired of spending hours manually vacuuming your in-ground pool? The Dolphin Explorer E70 is engineered specifically for in-ground and above-ground pools up to 50 feet, delivering unmatched floor, wall, and waterline cleaning with dual active scrubbing brushes and advanced Wi-Fi connectivity . As a product from Maytronics, the pioneer and world leader in autonomous robotic pool cleaners with over 40 years of experience, this premium Dolphin Explorer E70 combines smart connectivity with multi-layer filtration to keep your pool spotless without the hassle of hoses or booster pumps. Understanding how to choose the right pool equipment is essential for maintaining water quality, and organizations like the Pool & Hot Tub Alliance (PHTA) provide valuable industry guidance on best practices for pool maintenance.
Designed for In-Ground and Above-Ground Pools Up to 50 Feet
The Dolphin Explorer E70 was built to handle larger pools, making it the best premium Wi-Fi enabled robotic pool cleaner in its category. Unlike the Explorer E50 which offers a 2-year warranty, this model stands out with an industry-leading 3-year warranty covering parts and labor—the best protection of any robotic pool cleaner on the market . It covers pools up to 50 feet with its 60-foot PowerFlex cable featuring an anti-tangle swivel .
The dual active scrubbing brushes on the Dolphin Explorer E70 work effectively on all pool surfaces, including concrete, plaster, gunite, pebble, tile, vinyl liner, and fiberglass . At 24.3 pounds (11.04 kg), this unit is designed for stability and power while still being manageable for lifting and handling.
Setup for the Dolphin Explorer E70 takes under two minutes. Plug it into a standard outlet, press start, or schedule cleaning via the myDolphin Plus app, and walk away for 2 to 2.5 hours . No hose connections, no skimmer hookup, no booster pump. This unit runs completely independently of your pool’s filtration system, putting zero added load on your pump and consuming approximately 5 cents of energy per hour—making it 8 times more energy-efficient than suction and pressure cleaners.
Always-Connected Wi-Fi with myDolphin Plus App
The Dolphin Explorer E70 sets itself apart with always-connected Wi-Fi, allowing you to schedule your pool cleanings from anywhere using the myDolphin Plus app. This model connects to your home Wi-Fi, enabling remote control and scheduling of cleaning cycles through the mobile application. If Wi-Fi isn’t available, you can also connect using Bluetooth via the same app .
The Dolphin Explorer E70 includes a built-in weekly timer accessible through the app, allowing you to automate your pool cleaning schedule every 24, 48, or 72 hours . You can also select from multiple cleaning cycles: 1.5 hours (quick clean), 2 hours (standard), or 2.5 hours (extended clean) .
Waterline Scrubbing: 100% Floor, Wall, and Waterline Coverage
Unlike entry-level robots that only clean floors, the Dolphin Explorer E70 climbs walls and scrubs the waterline efficiently . This model features Dolphin’s powerful technology that ensures a spotless waterline. As the unit constantly grips the pool walls, it guarantees a thorough cleaning of the floor, walls, and waterline.
The Dolphin Explorer E70 uses PowerStream technology, where water is propelled out in multiple directions as the cleaner moves vertically up the wall, creating a constant grip for superior wall climbing and scrubbing performance . With its dual active scrubbing brushes, this unit provides intense scrubbing for an unmatched clean on all surfaces.
Superior Suction Power: Industry-Leading Performance
The Dolphin Explorer E70 boasts an industry-leading water suction rate—significantly greater than the 4,000 GPH found on many Dolphin models . This superior filtering capability results in the best clean available for your pool, capturing more debris and leaving your water crystal clear.
Active Scrubbing Technology: Removes Algae and Debris
Equipped with dual active scrubbing brushes (combining standard and combined brush types), the Dolphin Explorer E70 actively attacks and dislodges stuck-on algae, biofilm, and compacted debris from your pool floor, walls, and waterline . The brushes physically remove contaminants before the suction pulls them into the filter canister. A suction-only robot passes over stuck debris without removing it—this unit’s active brushes do not.
The active brushes on the Dolphin Explorer E70 work effectively on multiple pool surfaces. Research published through the National Swimming Pool Foundation highlights the importance of effective cleaning systems in preventing waterborne illnesses, and this model delivers precisely that.
CleverClean Advanced Navigation System
The Dolphin Explorer E70 uses the CleverClean™ advanced navigation system, which incorporates advanced scanning and mapping to ensure that every inch of your pool including walls, floors, and waterline gets cleaned using the most efficient route possible . CleverClean routes avoid obstacles such as main drains while quickly returning to its pre-planned route. The days of random patterns and inefficient pool cleaning are over. CBS News named the Dolphin Explorer E70 the “best robotic pool cleaner overall” for 2024, noting it’s a “newly-updated-for-2024 robotic pool cleaner and vacuum that comes with its own caddy” .
Important Note on Navigation: Unlike household floor vacuums that map a home’s entire layout, robotic pool cleaners use a combination of scanning and random pattern cleaning. The Dolphin Explorer E70 typically achieves full coverage after 2 cycles. Its mapping claims are effective but not perfect, and many users find the performance more than adequate for routine pool maintenance.
Multi-Layer Top-Loading Filter System: Superior Filtration
The Dolphin Explorer E70 simplifies pool maintenance with its top-loading multi-layer (dual-layer) filter basket. Easy to access and clean, this unit ensures your pool stays fresh and inviting. The model features a top-loading filter canister that you can access without flipping it over. Simply lift the filter out, unsnap the bottom, and rinse.
The multi-layer filter on the Dolphin Explorer E70 separates and filters rough, fine, and ultra-fine dirt for highly efficient filtration that’s clog-free . The basket is larger than other Dolphin Explorer robots and can be cleaned in just seconds . Effective filtration is critical for pool safety, as the Centers for Disease Control and Prevention (CDC) emphasizes, and this unit delivers exceptional filtration.
Smart Sensor Technology: Real-Time Pool Monitoring
The Dolphin Explorer E70 features advanced sensor systems including:
Full Filter Indicator – Alerts you when it’s time to clean the filter
Water Temperature Sensor – Get real-time water temperatures directly to your smart device
Out of Water Sensor – Automatically detects when the unit is no longer submerged
Pick-Up Mode – The Dolphin Explorer E70 conveniently waits at the edge of your pool for quick and easy removal
Energy-Efficient Operation: Reduces Water, Chemical, and Energy Usage
The Dolphin Explorer E70 runs on efficient motors with selectable cleaning cycles of 1.5, 2, or 2.5 hours. This unit is designed to reduce water, chemical, and energy usage with every pool cleaning. Research from the University of New South Wales confirms that conventional pool pumping systems consume substantial energy, with robotic cleaners like this one capable of dramatically reducing pool-related energy consumption.
The U.S. Department of Energy notes that pool pumps can be the second largest energy user in a home. The Environmental Protection Agency (EPA) provides additional resources on energy efficiency in homes, and this model aligns perfectly with these conservation goals.
