Main Difference Between the Models
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).
Comparison table
Even though the models Dolphin E20 and E30 are from the same model series, they have a lot of differences. Here further listed the main differences between Dolphin E20 vs E30; a more detailed explanation of these and other differences will be shown later in another chapter – Buyer’s Guide.
- Dolphin E30 can scrub a waterline and clean the floor and walls like Dolphin E20.
- Dolphin E30 has two active rubber brushes moving at the same speed as track wheels. Dolphin E20 has only one active rubber brush in the front.
- Both Dolphin cleaners have filter baskets. Dolphin E20 has a large basket, while E30 has an extra-large basket.
- Dolphin E20 is designed for small and medium swimming pools up to 33 ft, while Dolphin E30 can clean large swimming pools up to 50 ft in one cleaning cycle. In addition, E30 has a longer cable with a swivel – 60 ft.
All differences show that the E30 model is an advanced model with more extensive features than the E20. But still, E20 has a lot of advantages. Please see below a detailed description of two models proving that.
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.
attentionThe 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.

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.
attentionThe 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.
