Today was the first day I tried to vacuum myself, well of course I would run into problems. When I feel the vacuum there is all kinds of suction, but when I try to vacuum in the pool it will not pick up anything. I keep checking and I feel suction, but it won't work when Iplace in the bottom of the pool. I t won't even pick up the smallest item. I even put the hole directly over the debris and when I move the head there it is still on the pool floor. I really don't want to have to call the PB builder again, is it me?
