Buy Clear UVClear UV or Dolphin M550: our take
Clear UV and Dolphin M550 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 UV lists 2 active brushes, Intelligent navigation (C9 microprocessor), and Quad (2 pump + 2 drive) motors. Dolphin M550 lists 2 active brushes and CleverClean navigation.
Filtration and debris
Clear UV includes UltraFilter; Dolphin M550 includes Basket and UltraFilter. Both have documented fine-debris media, so basket capacity and ease of cleaning matter more than fine-particle capability. Dolphin M550 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 M550 provides a weekly timer and smartphone control. Clear UV uses a 59 ft corded cable with an anti-tangle swivel, while Dolphin M550 uses continuous corded power. Clear UV is listed at 27.6 lb versus 22.6 lb for Dolphin M550; that 5 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Both are listed at $1,999. Each lists a 3-year manufacturer warranty. Pool Express pick: Clear UV. Clear UV adds built-in UV-C water treatment while the robot cleans. Clear UV includes a 59 ft cable with anti-tangle swivel. Choose Dolphin M550 when it is the better fit for inground pools up to 50 ft that need floor, wall and waterline cleaning with app control, Pick-Up and a caddy.
