Dolphin E50 vs. E70 Face-to-Face Comparison Review

Now, to the main segment of this Dolphin E50 vs. E70 comparison review, how do the two robotic pool cleaners stack up against each other?

To ensure you make the right purchase decision, we have based this comparison on the essential considerations when choosing the best robotic pool cleaner. So, without further ado, let’s get into it.

1. Design, Dimensions, and Aesthetics

Is the design of the pool cleaner you want to buy appealing? Will it complement your pool and the sparkling blue clean water? Another important consideration here is the build quality. The aim is to get a pool cleaner with a robust build quality that can withstand any conditions in the pool or on the deck. The dimensions and weight are also critical, especially regarding portability and storage.

Dolphin E50 design

The Dolphin Explorer E50 boasts a robust and aesthetic design inspired by a robotic design, as you’d expect. We really like the build quality of this cleaner. It has been crafted from high-grade materials, as is Maytronics’ tradition. The E50 can withstand all weather conditions and offers years of service while maintaining its new shape.

The robot has been finished in white on most parts, but there is a black strip at the front, while the hose is blue. The dimensions of the Dolphin E50 are 22.244×17.598×13.189 inches, while the weight averages 19.228 lbs, so you can easily carry it around.

Dolphin E70 design

The Dolphin Explorer E70 is also a robust robotic pool cleaner with a muscular design, as you’d expect with a robot. The design is also impressive, blending in with your pool and the blue water. It also boasts a sturdy design courtesy of Maytronics’ great choice of materials. Like the E50, the E70 can withstand harsh conditions in the water and on the deck.

Regarding the finish, the E70 is also black and white but has more black patches than the E50, but the hose remains blue. The dimensions are 23.819×19.724×20.157 inches. As for the weight, it is a little heavier at 25.3 lbs.

2. Assembly and Usability

The next consideration is assembly and usability. Find out if the robotic pool cleaner requires assembly. If yes, how easy is the assembly? You definitely want a model that requires minimal assembly and, preferably, a plug & play design. Another aspect is usability. How user-friendly is the robotic pool cleaner? So, which Dolphin wins this round?

Dolphin E50 Assembly

One of the advantages of the Dolphin E50 is that it is easy to get started with it. No assembly is required as it boasts Dolphin’s “Plug’n Play” design (the robot comes assembled). What’s required is setting the power supply at least 10ft from the pool’s edge, connecting the floating cable, aligning the notch with the connector, and powering the unit on.

The next step is setting up the app by connecting the Dolphin to WiFi and finishing by creating a MyDolphin Plus account and syncing your robot with the app.

When it comes to usability, the E50 is excellent as it offers remote app operation and has a power cord with patented swivel technology, so you won’t have to worry about tangling. Also worth mentioning is Pick-Me-Up mode, which, when activated, the robot moves to the pool edge for easy retrieval.

Dolphin E70 Assembly

The new Dolphin Explorer E70 is pretty similar as it also bears a “Plug’n Play” design, so no assembly is required. The only thing required is setting up the power supply 10 feet from the pool’s edge, connecting the cable, and aligning the notch with the connector before powering on the unit.

Next, sync the robot with the MyDolphin Plus app, and that’s it. As far as operation, you also get access to intuitive controls from the app. The only difference is that the E70 gives you more features here, as we will discuss later.

The power cord also boasts patented swivel technology, so tangles, and kinks are not the order of the day. The Pick-Me-Up mode has also been retained so you can effortlessly retrieve your Dolphin from the pool.

3. Cleaning Orientation

There is a lot to discuss when assessing the cleaning orientation of pool cleaners. The first question is, what kind of pools has the cleaner been designed for? Remember, we have above-ground and inground pools. The pool surface materials also vary. Next, check the shape and pool length the cleaner is suitable for. You want to look into cleaning orientation to buy the right pool cleaner.

Dolphin Explorer E50 Cleaning Orientation

The Dolphin Explorer E50 is a pool cleaner designed for inground pools only, don’t use it in an above-ground pool. Instead, consider the Dolphin E10 robotic pool vacuum cleaner for above-ground pools or the E20. The Explorer E50 is also versatile enough to handle pools with different surfaces, be it concrete, vinyl, liner, or fiberglass.

It is also suitable for all pool shapes, including rectangular pools, free shape pools, hoppers, kidneys, mountain ponds, lagoons, single Roman, lazy ll, Grecian, true ell, you name it. Last, on pool size, the Explorer E50 may be a compact and lightweight cleaner, but it can comfortably handle a 50ft pool courtesy of a 60ft power cord.

Dolphin Explorer E70 Cleaning Orientation

Nothing changes in the Explorer E70 when it comes to cleaning orientation. It is similarly a robotic pool cleaner for inground pools. Don’t dare use it on an above-ground pool. It also boasts the versatility to handle different pool materials, from concrete and vinyl to fiberglass and liner pools.

You can also rely on the Maytronics E70 to clean any pool shape satisfactorily, for example, rectangular pools, kidney pools, round pools, free shape pools, hopper, mountain ponds, lagoon, single Roman, lazy ell, Grecian, true ell, etc. As for the pool size, it might be a newer model, but it still uses a 60ft power cord to clean pools of up to 50ft.

4. Cleaning Performance

The cleaning performance is perhaps the most crucial consideration when choosing between the Dolphin E50 and E70. The first question to ask here is, where can the robot clean? Is it the pool floor only, or can it also reach the walls up to the waterline? What is the suction rate? What about the scrubbing brushes? How long does a full cleaning cycle last? Let’s dig deeper to find out more about the cleaning performance of the two robots in today’s comparison review.

Dolphin E50 Cleaning Performance

Dolphin Explorer E50 has been designed for all-round cleaning. It can satisfactorily clean the pool floor and walls up to the waterline, where stains are common. When it comes to suction rate, the E50 is a 4000GPH pool cleaner. Now, onto the cleaning components. This robotic pool cleaner has been engineered with 2 brushes; a high-speed front scrubber and a standard back scrubber.

The two are active brushes that tackle all kinds of organic and metal stains, including algae stains, foliage stains, iron stains, rust stains, salt stains, you name it. While the brushes are tough on stains, they are gentle on the pool surface.

When it comes to the Dolphin cleaning cycles, there are 3; Quick (1.5 hours), Standard (2 hours), and, Enhanced (2.5 hours).

Dolphin E70 Cleaning Performance

The Explorer E70 is not different from the E50 in terms of where it can clean. It is meant for cleaning the pool floor and walls up to the waterline. But one thing that sets the two pool cleaners apart is the suction rate. To be precise, the new E70 delivers a higher suction rate, 5000GPH. Another difference is the brush system. The E70 has an advanced brush system dubbed High-Speed Dynamic Dual Scrubbing.

There are 2 brushes in the system, just like with the E50, but the E70’s brushes have been designed for deeper cleaning. From our experience, it tackled stains and dirt more effectively. These brushes, too, are gentle on the pool surface but tough on stains and grime.

As for the cleaning cycles, the E70 also has 3 cleaning cycles; Quick (1.5 hours), Standard (2 hours), and, Enhanced (2.5 hours), with Standard as the default cleaning cycle.

5. Filtration

The filtration system can also be the deal maker or breaker, not just the scrubbing system. Here, finding out what kind of filtration system the robotic pool cleaner on your wishlist has is essential. What kind of debris can it collect? Is it just the small debris, or can it also capture large debris? How friendly is the maintenance, and are there any extras such as full bin indicators? Let’s find out what the two have to offer here.

Dolphin E50 Filtration

The E50 is a great pool cleaner, even if your pool is under trees or in a sandy environment, courtesy of the multi-layer filtration system. Under the hood, it packs an extra-large top-access filter that can capture both minute and large debris from the fine silt and sand pebbles to twigs and cones.

One thing we like about this filter is the large capacity and top-load access that makes maintenance a buzz. The E50 filter also comes with a full bin indicator so you can know when it’s time to empty it.

Dolphin E70 Filtration

The E70 has the same multi-layer filtration system as the E50, so it is also great whether your pool is under trees that often drop twigs and cones or a sandy spot.

The filter design is also top-load for easy access during emptying and still features a full bin indicator. But one addition is that the E70’s full bin indicator shows 5 debris levels.

6. Navigation

As the name suggests, the Maytronics E50 and Maytronics E70 are robotic pool cleaners. They do all the heavy lifting independently. That means they have a navigation system. Navigation is vital when choosing between Dolphin E50 and Dolphin E70. Definitely, you want a model with a reliable and precise navigation system for efficient cleaning and entire-level coverage. How does the navigation system of the E50 compare to that of the new E70?

Dolphin Explorer E50 Navigation

The Dolphin Explorer E50, as the name suggests, is an explorer with the intelligence to know which routes to use and avoid obstacles.

The robot has been engineered with CleverClean™ Coverage – Precise Navigation System that leverages intelligent systems and sensors to scan and map your pool’s shape and size and, consequently, create a map to follow systematically to clean the pool, with high precision without missing any spot.

The system also senses large obstacles and avoids them.

Dolphin Explorer E70 Navigation

Dolphin Explorer E70 is also a smart explorer that relies on an intelligent system to find its way around a pool with any shape, from regular pool shapes to irregular ones. It also deploys CleverClean™ Coverage – Precise Navigation System.

There are intelligent systems and sensors for scanning and mapping your pool and sensors that detect large obstacles and tell the robot to change course.

Unlike your typical robotic pool cleaner, the Explorers hardly get stuck and guarantee entire level cleaning.

7. Maneuvering

When it comes to maneuvering, it’s crucial to find out about the propulsion system of the cleaner and how well it can handle different surfaces. The best robotic pool cleaner should have enough propulsion to take on any surface, be it the pool floor or walls. On the other hand, the tracks should be robust enough to go over large debris and grip to climb walls. So, what’s the best Dolphin robot pool cleaner in terms of maneuvering?

We really like the fact that Dolphin opted for continuous tracks instead of wheels for maneuverability. Tracks are better because they have better traction and can go over obstacles with fewer chances of getting stuck, like wheels. The E50 can climb even those sticky walls with great agility. The only obstacles it can’t override are the steps, ladder, ledges, and maybe pop-ups.

These tracks are also gentle, so no scratches are left behind, even on fiberglass pools. When it comes to the drive system, the Explorer E50 is powered by a single drive system that leverages just a single motor.

The new E70 has also been built with continuous tracks as opposed to wheels. The tracks also boast excellent traction to climb walls and can go over most obstacles along the way, except for the likes of ladders, ledges, steps, and pop-ups. The Explorer E70 tracks are also gentle on fragile pool surfaces, so you won’t have to worry about scratches in your covered pool.

The drive system is the main difference between the E50 vs. E70 in terms of maneuverability. While the E50 uses a single-drive system, the E70 has been upgraded to a dual-drive system with 2 motors. This gives it better propulsion and agility.

8. Convenience Features

You definitely want to go for a robotic pool cleaner to avoid the hassles of manual pool cleaners. That said, you need to consider the convenience features of the Dolphin cleaner you want to buy. Here, the priority should be features like programmed cleaning and remote operation. You may also want to pop in energy efficiency in your checklist. So, what’s the best model in terms of convenience? Is it the E50 or E70?

Dolphin E50 Smart Features

The Dolphin E50 comes packed with a wide range of convenience features.

First is 3 cleaning cycles so you can decide how fast or intensive you want the pool cleaned. Switch to Quick (1.5 hours) if the pool is not that dirty, Standard (2 hours) for general cleaning, and Enhanced (2.5 hours) if the pool is too dirty. The E50 is also customizable in that you can set cleaning schedules and choose the cleaning mode for each schedule.

Now, all these features are available via the MyDolphin Plus app on both iOS and Android platforms. Other features, including Pick-Me-Up mode, Delay mode, and the full filter basket indicator, are accessible via the app. For the record, this pool cleaner is compatible with both 2.4GHz WiFi and Bluetooth.
