Pierre Auger Observatory is the largest detector ever built for measuring the air-showers produced by ultra high energy cosmic rays. It combines a surface detector of 1600 water Cherenkov detectors spread over 3000 km2 with 27 telescopes. Currently the Pierre Auger collaboration is deploying an upgrade of the surface detector, AugerPrime. The surface detectors are being equipped with scintillators. We present the performances of the current surface detector and we describe the advantages on distinguishing the muonic from the electromagnetic components of the air-showers using AugerPrime. The performances of a detector for which the optical volume of has been separated in two are briefly described. A recent reconstruction of the properties of the air-showers for which a large fraction of the Cherenkov light has reached the telescopes will be also presented.
