An automatic juicer turns and pushes an upward facing juicing cone into a fruit for releasing and collecting juice. The juicer includes a base containing a motor, gear and shaft assembly which rises as a unit with the juicing cone. A fixed guide extends upward from the base and inner and outer shafts reside inside the fixed guide and are driven by the motor and gear assembly to rotate and advance the juicing cone into the fruit. The juicing cone, strainer and a bowl release and catch the juice. The outer shaft includes threads to vertically advance and retreat the outer and inner shafts when the outer shaft turns. The inner shaft rises with the outer shaft and lifts and rotates the juicing cone, thereby releasing juice from the fruit. The bowl is fixed to the base.
