Buy Clear SClear S or Dolphin EON 120d: our take
Clear S and Dolphin 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 S is intended for inground pools, while Dolphin 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 S lists 2 active brushes, Intelligent navigation (C9 microprocessor), and Quad (2 pump + 2 drive) motors. Dolphin EON 120d lists SmartMap navigation.
Filtration and debris
Clear S includes UltraFilter; Dolphin 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. Dolphin EON 120d has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
Clear S provides a weekly timer, smartphone control, and included remote control; Dolphin EON 120d provides a weekly timer and smartphone control. Clear S uses a 59 ft corded cable with an anti-tangle swivel, while Dolphin EON 120d uses cordless battery power. Clear S is listed at 27.6 lb versus 24.3 lb for Dolphin EON 120d; that 3.3000000000000007 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Each lists a 3-year manufacturer warranty. Pool Express pick: Clear S. Clear S runs from continuous plug-in power without a recharge between cycles. Clear S cleans floor, walls and waterline. Choose Dolphin EON 120d when it is the better fit for owners who value cordless handling more than automatic scheduling and continuous power.
