Hydro Dynamic Design Enhances Performance The Scuba SE?s hydrodynamic design allows the device to flow through your pool as it propels across the pool floor picking up dirt and debris. The design allows the Scuba SE to use less power in propulsion and dedicate that power to its cleaning capabilities. While other bulky corded cleaners consume additional power to simply move the Scuba SE is designed to utilize its maximum potential to clean your pool s floor and continue cleaning for a full 100 minutes.
