The hydrodynamic design of the Scube SE allows the device to glide through your pool as it glides across the bottom of the pool, picking up dirt and debris. The design allows the Scube SE to use less energy for propulsion and utilise this energy for cleaning performance. While other bulky corded cleaners use extra energy to simply move, the Scuba SE is designed to maximise its potential to clean the bottom of your pool and continue cleaning for a full 100 minutes.
