Buy Clear UVClear UV or Dolphin Proteus DX4: our take
Clear UV and Dolphin Proteus DX4 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. Clear UV has a published maximum pool length of 50 ft; the other model does not have a verified length in our source material. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Clear UV lists 2 active brushes, Intelligent navigation (C9 microprocessor), and Quad (2 pump + 2 drive) motors. Dolphin Proteus DX4 lists 1 active brush.
Filtration and debris
Clear UV includes UltraFilter; Dolphin Proteus DX4 includes Basket. That gives Clear UV the clearer documented edge for fine silt, pollen and sand. Dolphin Proteus DX4 has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Clear UV provides a weekly timer, smartphone control, and included remote control; Dolphin Proteus DX4 provides a weekly timer and power-supply controls. Clear UV uses a 59 ft corded cable with an anti-tangle swivel, while Dolphin Proteus DX4 uses a 60 ft corded cable with an anti-tangle swivel.
Price, warranty and the decision
