Some differences "clean" to "power clean"
A clean brings a barbell from the floor to the lifter’s shoulders. The power qualifier describes the height at which the bar is received and arrested: with the upper legs above horizontal. That is, in a clean, the athlete receives the barbell on the shoulders at some height between standing and squatting, continues into the bottom of a squat position, and finishes the lift by standing again. In a power clean, the athlete pulls the barbell identically, but must receive it on the shoulders and stop moving downward before sinking past a parallel squat. In other words, the power clean means the athlete must pull the bar higher, get under it quicker, and stop moving immediately
