Differences Between Dolphin Quantum vs Dolphin Sigma
Below is a summary of the specifications:
Design Comparison
The Dolphin Quantum and Dolphin Sigma are both designed for in-ground pools up to 50 feet, and each features a 60-foot swivel cable to eliminate tangling and enable smooth navigation across the pool. The Quantum, at 27 pounds, has a sleek, modern chassis designed for stability, especially during vertical wall climbing. Its hydrodynamic shape combined with PowerStream mobility allows it to maintain consistent contact with the pool surface, including steep inclines and complex curves.
In contrast, the Dolphin Sigma weighs slightly less at 24 pounds but is still solidly built for durability. Its three-brush layout adds more ground contact and balance during aggressive scrubbing and reduces any risk of flipping. The inclusion of Wi-Fi and Bluetooth hardware gives it a technological edge while keeping the form factor compact and robust.
Winner: Dolphin Sigma
With better balance, slightly lighter weight, and integrated connectivity hardware, the Sigma is the more refined and capable model in terms of construction and adaptability.
Cleaning Performance Comparison
The Dolphin Quantum utilizes dual HyperBrushes™, which rotate at twice the speed of standard brushes. These brushes are specifically engineered to tackle algae buildup, sticky biofilm, and calcium scaling along the pool’s surface. The Quantum is designed to cover the floor, walls, and waterline during every cleaning cycle. Its suction power of 4500 GPH ensures fast and thorough debris removal, and the SmartNav 2.0 mapping system minimizes overlap, allowing it to clean more area with less energy.
The Dolphin Sigma introduces a superior triple brush system, including commercial-grade center and side brushes that deliver exceptional scrubbing across wide surfaces. These brushes provide additional reach into corners and curved walls. It shares the same 4500 GPH suction rate but extends cleaning time to 2.5 hours, making it ideal for heavily soiled or larger pools. The SmartNav 3.0 system with gyroscopic navigation further improves path optimization, reducing missed spots and enabling more intelligent movement decisions.
Winner: Dolphin Sigma
The triple-brush design, longer cleaning time, and gyroscopic SmartNav 3.0 give the Sigma a measurable edge in thoroughness and surface reach, particularly for complex pool shapes and persistent debris.
Feature Comparison
The Dolphin Quantum offers premium-level hardware but limits its user interface to onboard controls. It includes a weekly scheduler and supports automated daily, alternate-day, or every-third-day cleaning cycles via the power supply. Its SmartNav 2.0 scanning system uses advanced software to chart cleaning paths and adjust routes in real time based on obstacles, but it lacks mobile control and wireless access.
The Dolphin Sigma incorporates Wi-Fi and Bluetooth connectivity, enabling full control via the MyDolphin Plus mobile app. Users can start, stop, schedule, and monitor the cleaning cycle remotely. It also provides maintenance alerts, filter status, and system diagnostics. The app syncs easily with both Android and iOS devices, and the onboard SmartNav 3.0 ensures even more precise route calculations through real-time gyroscopic feedback.
Winner: Dolphin Sigma
With app control, remote scheduling, and SmartNav 3.0, the Sigma significantly enhances the user experience with modern smart home compatibility and smarter navigation algorithms.
