The main function of the rapid drain flap is to quickly release residual water from the robotic pool cleaner when it is removed from the pool and to prevent back-flow or water surge that could impact performance. This feature is valuable because it ensures the cleaner is lightweight and easy to handle when being retrieved from the pool, and also prevents water from re-entering the unit, which could cause operational issues.
