The instructions and different youtube videos I see online say that the hose (leader and feeder hoses together) should be long enough so that your cleaner can be stretched to just reach the farthest point of your pool.
But that doesn't make sense to me, since that's just reaching to the farthest point of the pool *at the surface* and doesn't take into account depth. That also happens to be the deepest part of my pool. It seems like I would want the feeder hose alone to reach the farthest point of my pool at the surface, since that's supposed to remain at the surface, and then the the leader house gives it enough length to reach the bottom.
Am I missing something here? This seems like basic spatial reasoning.
