Where does the vacuum hook up for cleaning pool?

Normally a swimming pool had a static skimmer installed at the side of the pool this is where the surface water from the pool runs through a leaf basket to the filter. a vacuum plate fits over the leaf basket area. A hose can be plunged into the vacuum plate that hooks into a pool floor vacuum head. this head is connected to an aluminum pole or handle after that you use it the same as a normal vacuum cleaner. A pool shop will be able to advise you on the correct choice of hard ware. RB
