Buy Dolphin QuantumDolphin Quantum or Clear S: our take
Dolphin Quantum and Clear S 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. Dolphin Quantum lists 2 active brushes, SmartNav 2.0 navigation, and Dual DC motors. Clear S lists 2 active brushes, Intelligent navigation (C9 microprocessor), and Quad (2 pump + 2 drive) motors.
Filtration and debris
Dolphin Quantum includes XXL MaxBin and NanoFilters; Clear S includes UltraFilter. Both have documented fine-debris media, so basket capacity and ease of cleaning matter more than fine-particle capability. Dolphin Quantum also 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. Dolphin Quantum uses a 60 ft corded cable with an anti-tangle swivel, while Clear S uses a 59 ft corded cable with an anti-tangle swivel. Dolphin Quantum is listed at 18.3 lb versus 27.6 lb for Clear S; that 9.3 lb difference matters when lifting the robot from the pool.
Price, warranty and the decision
Dolphin Quantum is listed at $1,649 and Clear S at $1,749; Dolphin Quantum is $100 less. Dolphin Quantum lists a 2-year warranty compared with 3 years for Clear S. Pool Express pick: Dolphin Quantum. Dolphin Quantum uses the high-capacity XXL MaxBin for easier top-load debris handling. Dolphin Quantum includes a large-debris bin or bag for leaves. Choose Clear S when it is the better fit for inground pools up to 50 ft that need floor, wall and waterline cleaning, with fine debris.
