Right after it attaches to the filter pump it will start cleaning away. It has an adjustable mounting bracket so it can moved to be match the pool surface's water line. Maintenance for this skimmer is simple. Empty the skimmer when it gets full and clean as needed. Details:Blue and gray10" x 10" x 12.5"Corrosion-proof plasticFor outdoor use
