Buy Clear SClear S or Dolphin Proteus DX5i: our take
Clear S and Dolphin Proteus DX5i are compared on pool fit, cleaning reach, debris handling, controls and ownership details. The recommendation is based on the job the robot must do—not a simple feature count.
Pool fit and cleaning reach
Both robots are intended for inground pools. Both are rated for pools up to 50 ft. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Clear S lists 2 active brushes, Intelligent navigation (C9 microprocessor), and Quad (2 pump + 2 drive) motors. Dolphin Proteus DX5i lists 1 active brush.
Filtration and debris
Clear S includes UltraFilter; Dolphin Proteus DX5i includes Basket. That gives Clear S the clearer documented edge for fine silt, pollen and sand. Dolphin Proteus DX5i has the better documented path for bulky leaves and larger debris.
