Design Comparison

The Dolphin Cayman is built for pools up to 33 feet, featuring a compact and lightweight design that weighs only 14 pounds. This makes it ideal for smaller in-ground pools and for users who prefer a cleaner that’s easy to handle and remove from the water. It includes a 50-foot cable, but lacks a swivel mechanism, which means the cable may become tangled during long cleaning sessions.

The Dolphin Quantum, on the other hand, is designed for larger in-ground pools up to 50 feet. It includes a longer 60-foot swivel cable, ensuring tangle-free movement throughout the cleaning cycle.

The Quantum is significantly heavier at 22 pounds, reflecting its more robust frame and added hardware needed for advanced cleaning features. Its design is modern and industrial, with a larger filter capacity and heavier-duty tread system to grip and climb vertical surfaces with confidence.

Winner: Dolphin Quantum

With its larger pool compatibility, swivel cable, and rugged design, the Quantum offers superior build quality and coverage, particularly for larger or more complex pool layouts.

Cleaning Performance Comparison

The Dolphin Cayman features a HyperBrush™ active roller that spins twice as fast as conventional brushes, agitating dirt, algae, and debris from pool surfaces with impressive efficiency. It offers a suction rate of 4000 GPH, which is sufficient for small to medium pools. It cleans the pool floor and walls in a quick 2-hour cycle, but it does not include waterline scrubbing, limiting its reach to submerged surfaces only. The Cayman’s fine filter basket performs well against sand, leaves, and bugs, but lacks the ability to trap ultra-fine particles effectively.

The Dolphin Quantum takes performance to a higher level with dual HyperBrushes, offering double the scrubbing coverage. It can clean not only the pool floor and walls but also the waterline, which is where oils, sunscreen, and floating debris often accumulate. It operates at a stronger 4500 GPH suction rate, meaning faster, more powerful cleaning. The 2.5-hour cleaning cycle allows more thorough coverage. Its dual-cartridge filtration system includes both fine and ultra-fine filters, capturing everything from large debris to microscopic particles with ease.

Winner: Dolphin Quantum

With more suction, dual brushes, extended cleaning reach, and superior filtration, the Quantum delivers a deeper and more comprehensive clean.

Feature Comparison

The Dolphin Cayman includes a basic weekly scheduler via its power supply. Users can program it to clean every day, every other day, or every third day, without having to restart it manually. There is no Wi-Fi or Bluetooth support, and the navigation is straightforward, relying on pre-set patterns rather than intelligent scanning.

The Dolphin Quantum features SmartNav 2.0, an advanced scanning system that maps the pool’s layout and creates an optimized cleaning route. This reduces overlapping passes and ensures that every inch of the pool is cleaned more efficiently. Like the Cayman, it includes a weekly timer, but thanks to SmartNav’s adaptive navigation, it completes each cleaning cycle more intelligently. While it still lacks Wi-Fi or mobile app control, the improved logic sets it apart from other non-connected cleaners.

Winner: Dolphin Quantum

SmartNav 2.0 gives the Quantum a clear edge, delivering smarter cleaning and minimizing wasted energy and time.
