Dolphin Explorer E20 versus Dolphin Quantum

Comparing the Dolphin Explorer E20 to the Dolphin Quantum

Both are designed to effectively clean your pool's floor, but only the Dolphin Quantum cleans your pool walls and waterline. The Dolphin Explorer E20 will miss the walls and stay entirely on the pool floor. Breaking down their filters, the Dolphin Quantum® includes 2 filter options for its oversized basket: NanoFilters and Standard Filter. The Dolphin Explorer E20 includes only one filter option, the Standard Cartridge Filter, but won't include the NanoFilter.

Ultimate Pool Coverage of the pool floor, walls, and waterline

Filter Options

NanoFilters™ are the newest innovation out of the Dolphin ProLine™. These filters help capture microscopic particles that pass through the standard filters.

Quantum's NanoFilter™ - Our Largest Ever.

Engineers equipped the Quantum with the largest NanoFilter ever. At over 400 square inches of space, the NanoFilter provides advanced filtration to stop the most difficult of particulate, including bacteria, algae, oil, leaves, and more.

The Dolphin Quantum includes:

• Oversized NanoFilter Basket (Our Largest NanoFilter Ever)
• Standard Cartridge Filter Basket

The Dolphin Explorer E20 includes:

• Standard Cartridge Filter

Unlock Your Robot’s Full Potential

There are two types of filters available on modern robotic pool cleaners. The first-generation robots will have a filter consisting of a large pore plastic mesh. The second-generation type is the NanoFilter™ cartridge, which is a high-efficiency particulate filter. The large pore mesh filter is the more basic type and is found on many discount pool cleaners, while the Nanofilter is the more advanced option. Under a microscope, you can see the Nanofilter’s individual fibers intersecting to create a tight mesh. This webbed structure is able to sieve even the smallest of micron particles. Additionally, the filter’s deep pleats provide a larger surface area, meaning more waterborne particles can be trapped while having relatively low resistance to waterflow.

NanoFilter™ vs Standard Filter

The NanoFilter™ also has the benefit of being able to absorb oil, which is beneficial for keeping sunscreen and scum lines from forming on the pool’s surface. Overall, the pleated Nanofilter is more efficient than the plastic mesh filter at capturing all types of microscopic waterborne particles, including pollen, algae, bacteria, pet dander, and other debris. Not only does this improve the amount of contaminants that are removed from the water, but it also leads to a higher level of clarity and sparkle in the pool. The Nanofilter serves as an important booster to the pool’s main filter, and for this reason, it is the preferred choice for many pool owners.

The NanoFilters™ capture more dirt, sand, and even oil out of your pool than the standard filter cartridges, making a NanoFilter™ a must-have for any pool robot. Without it, these particles will be left inside of your pool and can lead to poor water chemistry.

Ease of Use

Both robots have a similar setup process and weigh about the same. To set up either one, simply plug the power supply into an outdoor outlet, plug the unit into the power supply, drop the unit into the water, and press start. Both robots have a weekly timer with options for daily, every other day, and every three-day cycles.

Cleaning Performance

In terms of cleaning performance, the Dolphin Quantum® is capable of cleaning pool floors, walls, and waterline (also called the scum line), which is the most vulnerable part of the pool to dirt, grime, and algae buildup. This is especially important for robotic pool cleaners because if the bot doesn't clean the scum line, you'll still need to manually brush the pool afterwards. The Dolphin Explorer E20 only covers the pool floor, missing the walls and waterline entirely. While it will clean your pool floor, expect it to be unable to clean you pool walls and waterline.

Anti-Tangle Swivel

Only the Dolphin Quantum includes an anti-tangle swivel, which helps minimize cord tangling. The Patented Tangle Free Swivel from Maytronics allows the robot to rotate 360 degrees without your cord getting tangled. Without it, the Explorer E20's cord can get tangled and caught up in your pool.
