We had a composite pool installed 2 years ago. I was a little worried about the maintenance requirements of a pool so I had the pool floor automatic popup cleaning system installed. After 2 years experience I am amazed at how efficient this cleaning system is. I guess over the two years I have had virtually no need for manual cleaning. We could not be happier with the pool, it has transformed the entertainment area of our house and has been a breeze to look after.
