Who the Dolphin Proteus Lineup Suits

The Proteus DX3 is a solid wall-climbing cleaner for pools up to 33 ft. Move to the DX4 or DX4 Plus for a 50 ft pool and a weekly timer, and to the DX5i if you want the app. For fine debris or a longer warranty, the Max-Series™ Cayman and Quantum are the better buy.

Dolphin Proteus buying guide

What separates the models, and which current Dolphin to price each one against.

DX1 to DX5i

The DX1 and DX3 clean floors and walls on pools to 33 ft in a 2-hour cycle. The DX4 covers 50 ft pools floor to waterline with a weekly timer; the DX4 Plus is the updated version of that class. The DX5i adds myDolphin™ Plus app control.

Where Proteus fits

Proteus sits beside the Nautilus line in price and a step below Max-Series™ in brush and filter technology. If the pool is under 33 ft and the debris is leaves and dirt, the DX3 does the job; for sand and pollen, the Cayman's MaxBin™ with NanoFilters™ is worth the difference.
