Powerstream Technology

The Dolphin DX4 Proteus uses the same Powerstream Technology as the Maytronics Active 20 which allows for maximum grip during vertical cleaning. This feature works by propelling water in multiple direction as the cleaner moves vertically up the pools wall, this in return creates constant grip. This feature also allows for the Dolphin Proteus Dx4 to perform a more precise clean and allows it to remove any algae built up on the waterline.

Fine and ultra fine filtration

Much like the Dolphin S300, the Dolphin Proteus Dx4 comes loaded with two different types of filters. Fine for debris like leaves and small sticks, and ultra fine for small particles like dust, and pollen. To make it even better these filters are easily removed, and simple to wash!

CleverClean technology

When the Proteus DX4 pool cleaner is put in the water for the first time it will spend the first 20 minutes using its CleverClean system to map out the most efficient path to take while cleaning your pool.
