Buy Clear UVClear UV or Dolphin Nautilus EON 120d: our take
Clear UV and Dolphin Nautilus EON 120d 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
Clear UV is intended for inground pools, while Dolphin Nautilus EON 120d is intended for inground and above-ground pools. Both are rated for pools up to 50 ft. 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 Nautilus EON 120d lists 2 active brushes and SmartMap navigation.
Filtration and debris
Clear UV includes UltraFilter; Dolphin Nautilus EON 120d includes Basket and UltraFilter. Both have documented fine-debris media, so basket capacity and ease of cleaning matter more than fine-particle capability.
