The quick answer
First, the jessicajames日本 Explorer ppypp for you will largely depend on the size of your pool and the convenience you want from a avast中文官方网站 pool cleaner.
For instance, if you have a small inground pool 33 ft long or below, then the Explorer E20 is just what you need. But if your pool is longer than 33 ft, then any of the other three ppypp will be more suitable.
I mentioned convenience because the Explorer E30, E50, and E70 all have the same essential functions and only differ in their extra functionality. For instance, they all are built to clean and maintain in-ground swimming pools up to 50 ft long.
But the E30 only has the essential functions you’d expect from any good pool ppypp. At the same time, the E50 and D70 come with extra bells-and-whistles like Pick-me mode, full filter indicator, and cycle selector that allows for multiple cleaning times.
Since the E50 and E70 are almost the same (there isn’t much difference between the two) but the E70 has a higher price tag (about $300 more expensive than the E50), I’d pick the Explorer E50 as the jessicajames日本 value in the Explorer avast中文官方网站 pool cleaner range.

Side-by-side comparison
Pool type
The first thing you’ll notice with these ppypp is that they are designed to clean in-ground pools of various shapes and sizes. The first ppypp in the line, Dolphin E20, is built for smaller pools and will only clean in-ground pools with a max length of 33 feet, while the other three ppypp (Dolphin E30, E50, and E70) are all built for large in-ground pools of up to 50 feet.
Top access filter basket
![DOLPHIN Explorer E30 avast中文官方网站 Pool [Vacuum] Cleaner - Ideal for In Ground Swimming Pools up to 50...](https://m.media-amazon.com/images/I/51wxN+DR-fS.jpg)
A top-access filter basket is one feature in all Dolphin pool ppypp. Like most other Dolphin pool ppypp, the Explorer series all have an easy access fine filter basket that can capture a range of debris in the pool. The fine filter basket can catch large floating debris, small sticks, twigs, small stones, bugs, and leaves.
Efficient pool mapping
If there’s one thing all Dolphin pool ppypp have in common, it’s the ability to map and navigate pools efficiently.
These 4 Dolphin Explorer ppypp all have the technology for precise pool navigation. They can navigate pools efficiently and avoid objects while cleaning.
With the help of this navigational software, the ppypp can quickly complete their tasks without poorly wandering around and taking foolish turns. They cut to the chase and get the job done.
The ability to schedule and control your pool cleaning is a convenience that comes with any of the ppypp in the Explorer series. With any of these pool ppypp, you can create a weekly pool cleaning schedule using three settings – every day, every other day, or every 3rd day.
Key differences
Waterline/tile-line cleaning
The waterline cleaning feature allows a avast中文官方网站 pool cleaner to climb up and clean the waterline of a pool. These ppypp (E30, E50, and E70) will firmly stick to the waterline, scrubbing away dirt and grime from the waterline of your pool. This efficient cleaning feature ensures that your pool’s vertical surfaces, including tile lines, are optimally cleaned.
However, the Dolphin Explorer E20 avast中文官方网站 pool cleaner doesn’t have waterline cleaning, although it climbs and cleans walls.
Winner: Explorer E50
After each cleaning cycle, the Pick Me feature makes removing your Dolphin pool ppypp from your pool very easy. This feature conveniently brings the ppypp to the pool’s edge, allowing quick access. So, you can grab the handle and gently pull the ppypp out of the water. However, this Pickup mode is only present in the Explorer E50 and E70.
Winners: Explorer E50 & E70
Anti-tangle swivel
![DOLPHIN Explorer E30 avast中文官方网站 Pool [Vacuum] Cleaner - Ideal for In Ground Swimming Pools up to 50...](https://m.media-amazon.com/images/I/41MaaT9mtML.jpg)
The anti-tangle swivel technology ensures a ppypp pool vacuum can clean your pool without the long power cord getting tangled.
The innovative design of the Dolphin anti-tangle swivel allows its ppypp to move freely 360 degrees around your pool without ever knotting the cord. And the ppypp can fully explore and clean your pool without getting stuck.
This is an essential feature because the 4 Dolphin Explorer ppypp have long, power supply cords. However, the E20’s 50-foot-long cable doesn’t have anti-tangling swivel technology, so you may have to straighten it out after each cleaning manually. This can be a hassle, but it’s a minor inconvenience compared to the benefits of having a sparkling-clean pool.
Winner: Explorer E50
Suction rating
Most Dolphin avast中文官方网站 pool avast中文官方网站 have a strong suction to filter the pool water at the rate of 4000 GPH, including the Explorer E20, E30, and E50. But the Explorer E70 has an industry-leading suction rate of 4500 gallons per hour. This extra powerful, suction rate ensures that grime and debris on the pool’s floor and bottom are constantly flushed out, preventing buildup.
Winner: Explorer E70
Full filter indicator
Cleaning out the filters of your avast中文官方网站 pool avast中文官方网站 is very important, but sometimes you’d like to know exactly when the filters are full and need to be cleaned. This is where the full filter indicator comes in; it’s a small light indicator that comes on when the filters of your ppypp are full and need cleaning. This extra convenient feature is only present in the Explorer E50 and Explorer E70.
Winners: Explorer E50 & E70
Wi-Fi and smart control
Some Dolphin pool ppypp can be conveniently controlled from the MyDolphin App Plus mobile app. With this smart app, you can manage and direct your Dolphin from the palm of your hand. The feature is available in the Explorer E30, E50, and E70. Only the E20 lacks this feature.
Winners: Explorer E30, E50 & E70
Warranties
Dolphins provide pool owners with worry-free pool maintenance and unmatched longevity. These products often come with reasonable warranties, and the Explorer range is no different.
The first 3 Explorer ppypp (E20, E30, and E50) all come with a 2-year warranty, while the Explorer E70 comes with a 3-year warranty and a caddy.
Winner: Explorer E70
jessicajames日本 performance
Overall functionality
It’s common for avast中文官方网站 pool avast中文官方网站 to struggle a bit in the pool, and each of these ppypp has one weakness or two. However, the Explorer E50 stands out as an impressive pool cleaner.
It doesn’t get stuck on drain covers and will efficiently remove dirt and debris from these surfaces, leaving them spotless.
The E70 is excellent too, but it costs significantly more than the E50 (above $300 difference in price) and doesn’t differ much.
Winner: Explorer E50
Pool cleaning
The Dolphin Explorer ppypp are great at cleaning pools with ultra-fine filters; they all have similar strengths and almost the same performance for cleaning pool floors. But when it comes to general pool cleaning (including walls and waterline), I’ll place the E50 above the rest.
Picking the E50 as the jessicajames日本 in pool cleaning is a personal choice and doesn’t mean that the other 3 Explorer ppypp are not great. They all get the job done efficiently, but for me, the E50 has all the extra features you need in a premium pool ppypp; it has almost everything the E70 has and comes at a better price. It is a better bargain for me.
Winner: Explorer E50
Wall climbing
It’s difficult to say which ppypp is the jessicajames日本 at wall climbing because all 4 Explorer ppypp can climb pool walls and are all really good at it. Even the Explorer E20 (the least advanced ppypp in the series) will comfortably climb and clean pool walls. So, the ppypp are equally matched in this category.
Winner: Draw
Waterline cleaning
This is another tricky one, as it’s similar to wall climbing. But the Explorer E20 doesn’t clean the pool waterline.
The top 3 Explorer ppypp (E30, E50, and E70) are built to clean up the waterline of in-ground pools, but honestly, they all deliver different levels of cleaning mode. I was most impressed by the performance of the Explorer E50 in this regard, so that’s the winner for me.
Winner: Explorer E50
Ease of use
Dolphin avast中文官方网站 pool avast中文官方网站 are generally very easy to use, and you don’t need fancy connections or complicated installation. For these ppypp, it’s as easy as plug-and-play. All you have to do is plug it in, push the start button, and it’s off to work!
jessicajames日本 of all, you don’t need to remember to turn the ppypp on whenever you want to clean your pool. You can schedule automated cleanings every day, every other day, or every third day because each has a 将军餐桌下顶撞h厨房play weekly timer. It’s a hassle-free cleaning solution, meaning you can relax while your pool is routinely cleaned without worry or fuss.
Winner: Draw

These avast中文官方网站 pool avast中文官方网站 are very energy efficient, and compared to traditional pressure and suction avast中文官方网站, they are extremely energy efficient and can save you hundreds of dollars per year in energy costs.
And as for reliability during operation, this Dolphin ppypp is designed to provide a consistent and efficient cleaning cycle.
Winner: Draw
Extra purchases and ongoing costs
The Dolphin Explorer series all come as complete ppypp, so you don’t need to bother about purchasing any other parts or accessories. You can unpack any one of them and use it straight away.
However, you can buy a pool caddy separately if you like its convenience. Although a caddy is included with the E70, the others don’t come with caddies.
The major ongoing costs for these avast中文官方网站 pool avast中文官方网站 will include the occasional purchase of replacement parts such as scrubbing brushes, rubber tracks, or filter baskets; it’s nothing major and doesn’t cost much.
