Vacuuming an inground swimming pool is a standard maintenance procedure. Skimmers only remove dirt and debris that are afloat or suspended in the water. Contaminants that sink to the bottom of the pool or stick to the sides will not be removed by skimming. Often these particulates can be brushed off the bottom and sides, stirring them up so they may be gradually cleared by circulation through the skimmers. However, there are times when only vacuuming will completely clear the pool, particularly if you want fast results. A pool vacuum may be used with two valve settings on the sand filter, depending on the level of particulates in the water.
