Abstract: A method for rinsing a treatment cell of a workpiece surface treatment system, which obtains a surface-treated workpiece by sequentially carrying the treatment cell containing the workpiece to a series of apparatuses for operations in the respective apparatuses is provided. A surface treatment apparatus performs a surface treatment on the workpiece by receiving the treatment cell from a carrying apparatus and supplying a surface treatment liquid to the inside of the treatment cell while rotating the treatment cell. A workpiece collection apparatus collects the workpiece by receiving the treatment cell from the carrying apparatus, inverts the treatment cell, and squirts the inside of the treatment cell with water from below to flow out the workpiece. The carrying apparatus carries the treatment cell to the surface treatment apparatus, and then to the workpiece collection apparatus.
