Any idea how to get the darn thing to move? It is stuck in the shortest postion and I am killing myself trying to clean the deep end. I have tried moving it when it is completely dry, completely wet, banged it up against stuff to "loosen" it - it is not budging. My husband has also tried and can not get it to move. I thought about spraying WD40 on it but worried about the oil getting in the pool. Any other suggestions or do I need to go buy another one? Thanks!
