Filter Type

The Dolphin Proteus DX4 comes with ultra-fine filters, giving it an edge over the DX3, which is equipped with standard fine filters. These ultra-fine filters in the DX4 can trap even the smallest particles, ensuring a higher degree of cleanliness in your pool.

Which Would I Choose?


The final verdict comes down to your pool cleaning needs and budget.

If you’re working with a tight budget but still require efficient floor cleaning, the Dolphin Proteus DX3 would be your best bet. It’s simple, effective, and provides excellent value for money. Plus, it’s lightweight, making it a breeze to handle when it’s time to remove it from the pool.

On the flip side, if you’re looking for comprehensive cleaning coverage and convenience features like the Weekly Scheduler, then the Dolphin Proteus DX4 might be worth the extra investment. Its ability to clean every inch of your pool, coupled with the convenience of setting a cleaning schedule, sets it apart. The DX4’s ultra-fine filters also ensure a higher degree of cleanliness, trapping even the smallest particles.
