Dolphin E20 vs E30 – Detailed comparison

Dolphin E20 vs E30

Maytronics has produced products for pool maintenance for about 40 years. They have distributors in more than 50 countries and provide technical support 24/7 for their customers. They specialize in innovative robotic pool cleaners for residential and commercial pools – more than ten different Dolphin models.

An exciting fact is that, nevertheless, Maytronics produces a lot of robotic pool cleaners of different series; in reality, most of them are very similar in functionality to each other. For example, Dolphin E20 is similar to Dolphin S200, Dolphin Cayman, and Dolphin Nautilus; Dolphin E30 is similar to Dolphin S300 and Dolphin Quantum.

That is why today’s comparison is between top-rated and effective models Dolphin E20 vs E30, as these models also represent the other models. Previously, Dolphin E20 was compared with Dolphin E10 (a simple standard cleaner with limited functionality).

Detailed Product Review

2. DOLPHIN Explorer E20 Robotic Pool Vacuum Cleaner

Dolphin E20 is a trendy model of the robotic pool cleaner. It is compact, lightweight, and suitable for all types of inground pools up to 33 feet, making your pool maintenance a nice event.

You do not need to install this cleaner; plug it into a power control unit, put it in the water, and push a start button. Weekly Timer allows starting the cleaning procedure automatically for one week – every day, every other or third day. However, the cycle is presented only in one mode – 2 hours– no enhanced or delay features are available. After you push the button on the Power control unit, it will start to move with two-track wheels and a rubber brush with high-speed start scrubbing the pool surface, eliminating any dirt or organics. All debris up to fine particles is effectively sucked into the inlet on the bottom and goes to the filtration bucket.

The control is executed only through a power control unit and one push button connected to the electricity grid with a black cable from one side and a blue cable of 50 ft. length to the robotic cleaner. There are no obstacles for Dolphin E20; it cleans all drains without stopping. A powerful motor with suction of 4000 rpm allows climbing and cleaning walls, but not so good with steps. Patented Clever Clean Technology will create a map of your swimming pool to ensure complete coverage within a cleaning cycle of 2 hours.

After any working day, you need to take the cleaner out of the water with ergonomic water and clean the filter. It will not take much time, as the robotic cleaner is equipped with an automatic quick water release function. The filter basket has access within one click, opening the lid and allowing to take out the large capacity filter easily. This filter, like many others, should be cleaned with fresh water from a hose, and proper cleaning will last for many years, all seasons long. The filtration system with a single filtration level provides proper debris capture.

attention

Unfortunately, the filter does not have a full bag indicator, and to provide each time effective cleaning before each cycle should be properly cleaned.

The proper storage should be in the shade and dry place. A caddy cart purchased separately is a perfect storage way. Most of the time, the most attention should be paid to the cable, and store it in coils, but once a week, unplug and stretch it in the sun for a couple of hours to prevent tangling. You can keep the cleaner for a week in the water but with a clean filter.

Like any other pool cleaner, it saves your money, and the work cost is amazing – only 5 cents per kWh of cleaning cycle.

Pros
  • Fully automatic mode with the possibility of a week ahead program of settings
  • Robust floor and wall scrubbing
  • Top easy access large filter
  • Light weight
  • 50 ft cable length
  • For all inground pools, small or medium sizes up to 33 ft of all shapes
  • Cleaning cycle 2 hours
  • No extra pumps are required for working only electricity
  • Budget friendly
Cons
  • No delay feature or shortened cleaning cycles
  • No smartphone application or remote controllers
  • No waterline scrubbing
  • Only one rubber brush in front
  • No swivel on the cable
  • No indicator of full filter

2. Dolphin E30

If you desire more advanced pool robotic cleaner features, then Dolphin E30 is a better choice. In addition to all advantages of Dolphin E20, the E30 model is super-efficient in waterline scrubbing. This model’s design is very similar to E20, with the same color pattern, but the lid is black, not white. It also comes with a power supply control panel that executes the control function. It has a button for setting a timer for the upcoming week (start the program automatically every day. every second or third day). The panel should be plugged into the socket with a black cable and located 12 ft. from the pool. The excellent option of this cleaner is as it climbs the wall, the longer blue cable – 60 ft. with a swivel prevents its tangling.

The cleaner is moving around the pool without interruption and achieving all corners. It has an additional rubber brusher with a slightly smaller size on the back, allowing scrub the pool surface twice efferently. The brushes rotate with the speed of the robot. The filter basket has the same access from the top, and the basket allows to collect all leaves and debris with extra-large capacity and, after that, easily clean it. Do not be afraid to take the cleaner out of the water; the debris will not go back into the water; they are trapped in the filter basket even with a function of fast water release. You can purchase an optional ultra-fine cartridge assembly if you have a lot of fine dirt. This optional basket will be installed instead of the original one and requires the exact cleaning procedure. Do not let the filters dry before they are clean.

attention

Clogged filters reduce the effectiveness of cleaning.

The start-up procedure is as usual: connect the panel to the electricity, pull the cleaner into the water and push the start button on the panel. Thanks to the navigation system Cleaver clean system, the pool up to 50 ft. will be thoroughly cleaned, and the cleaner automatically will turn off in 2 hours. When the Dolphin E30 is climbing the wall and reaching the top, water is extracted from two jets from both sides, allowing the cleaner to stay horizontally for a while.

When pulling the cleaner out of the pool, you need to pull it by the cord up to the surface edge of the pool, and then grab the handle and take out the cleaner only with a handle. As Dolphin E20, E30 has a limited warranty on manufacturer’s defects and does not include wear and tear of brushes or tracks.

This cleaner will definitely extend the life of your pool system and save energy with every cleaning cycle.

Pros
  • Clean waterline in addition to walls and a floor
  • 60 ft. cable with a swivel
  • 2 active rubber brushes – on the front and back
  • For all inground pools up to 50 ft of all shapes
  • It is possible to set a schedule for one week ahead
  • No pumps are required for work, only electricity
  • Extra-large filter basket with easy top-access
  • Light weight
  • Cleaning cycle only 2 hours
Cons
  • No remote control or delay feature
  • No fast or enhanced cleaning cycles
  • A little bit more expensive than Dolphin E20
  • No indicator of full filter

Design and functionality

Dolphin E20

Dolphin E20 Design
Dolphin E20 is a black efficient pool cleaner with a white lid and handle, grey track wheels, and grey rubber active brush in front. During two hours of the cleaning cycle, it provides powerful suction of debris using a large filter basket and scrubs the floor and the walls.

Dolphin E30

Dolphin E30 Design
Dolphin E30 is a black super-efficient pool cleaner with a black lid and white handle, two-track wheels on the back, and two grey rubber brushes in front and back. It sucks debris into an extra-large filter basket and scrubs a waterline, walls, and a floor during each 2 hours cleaning cycle.

verdict

The slight difference between Dolphin E20 vs E30 in color scheme is not significant, but E30 has an additional rubber brush on the back. That provides better pool surface scrubbing. Also, during the same two hours cleaning cycle, E30 can scrub the floor, walls, and a water line; meanwhile, E20 can scrub only the floor and walls. Another significant difference – E30 has a larger filter basket. So, the E30 is more functional than the E20 with the same design.

How to choose the Best Pool Robotic Cleaner?

After reading the detailed description, and if you have already decided to buy a robotic pool cleaner, please go through the list of main parameters that should determine the choice of the best pool robotic cleaner for your swimming pool. The cleaner technical characteristics should ideally match the requirements of your swimming pool maintenance.

Type of pool surface.
The fiberglass swimming pools require more gentle scrubbing with rubber brushes than concrete ones.
Pool size and type.
During the standard cleaning cycle, the cleaner can scrub only the pool size per design effectively. You can definitely put a cleaner in different pool spots if you have a larger swimming pool. Also, some cleaners are designed only for inground pools or above grounds, and some for both.
The cleaner functionality.
Some cleaners can clean only the floor, some floor and walls, and only minor parts can additionally clean a waterline. If you already have some devices to scrub, for example, a waterline, you can skip this function. It makes the robotic pool cleaner significantly more expensive.
Suction power.
Good robotic cleaners have a suction of 70 gallons per minute and higher. This value ensures suction debris from large to small.
Type and size of the filter.
The amount and type of debris should determine the filter type and size. If you have a lot of leaves, you should choose a filter with a big capacity. If you have a lot of fine particles, you should use a filter with a mesh size of 5 microns or less.
Available control function.
Not all cleaners have remote controls or shortened cycles.
Warranty. Robotic cleaners are expensive machines; it is better to have an extended warranty to be safe in a free-of-charge change of broken details.
The Manufacturer.
The trustable Manufacturer with technical support 24/7 is a guarantee for the long life of your robotic pool cleaner.
The parameters listed are the most important for every pool owner; it is almost impossible to skip one of these by choosing the robotic cleaner. Parameters such as the color, shape, number of wheels, weight, and type of filter access are also essential but should be considered secondary, considering the available budget.

Hi! I'm Markus Robertson, and water is my passion. Five years ago, I graduated from the University of California-Los Angeles and was going to become a professional marine biologist. However, my fate had other plans for me, and due to family problems, I had to find a more stable and well-paid job. I had only one wish for my job to be connected with water. During this period of my life, I worked as a sales manager at Olympic Pool & Spa Supplies. The job helped me learn everything about swimming pools and related pool equipment, as well as how to choose the best option and what to pay attention to. Having worked there for three years, I decided to start my own blog about pools, where I can tell people about the best new pool equipment models and share my knowledge and experience. A marine biologist by education, I became a pool blogger by trade. Now I'm glad I can help the guests of my store and the visitors of my blog know a lot of exciting things about pools, their types, best pumps and filters, necessary equipment maintenance, and so on. I welcome all people who want to choose a proper basin and the stuff to my blog! Hope you'll find this information interesting and useful!
