The problem lies when cleaning the pool.
In fact, every 15 days I brush with a broom, the fund of the pool, and a light cloud green / brown forms.
Before the establishment of the skimmer, I presented this slight cloud suspension to filter input mouth, located halfway up and was immediately absorbed. This mouth location, considered by the pool builder, allows maximum absorption of fine particles in suspension.
Now this light cloud is no longer absorbed, or much less quickly.
So, what we gain with this surface cleaning accessory, you lose performance when cleaning the pool unless the pool provides more input mouth (which is not my case) .
Hence an evaluation at 3 stars.
