Buying guidance

Clear S or Dolphin Explorer E70: our take

Clear S and Dolphin Explorer E70 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 Explorer E70 lists CleverClean navigation.

Filtration and debris

Clear S includes UltraFilter; Dolphin Explorer E70 includes Basket and UltraFilter. Both have documented fine-debris media, so basket capacity and ease of cleaning matter more than fine-particle capability. Dolphin Explorer E70 has the better documented path for bulky leaves and larger debris.

Controls and day-to-day ownership

Both models provide a weekly timer, smartphone control, and included remote control. Clear S uses a 59 ft corded cable with an anti-tangle swivel, while Dolphin Explorer E70 uses a 60 ft corded cable with an anti-tangle swivel.

Price, warranty and the decision

Clear S is listed at $1,749 and Dolphin Explorer E70 at $2,099; Clear S is $350 less. Each lists a 3-year manufacturer warranty. Pool Express pick: Clear S. Clear S is listed $350 lower. Clear S includes a 59 ft cable with anti-tangle swivel. Choose Dolphin Explorer E70 when it is the better fit for inground pools up to 50 ft that need floor, wall and waterline cleaning, with fine debris.
