What command can i use to clean the content of Output windows at the beginning of the workflow execution?

you cannot, that is a UI thing …

UNSUPPORTED: But you could hi-jack the window from invoke code

MainWindow window = RobotInstance.instance.Window as MainWindow;
window.Tracing.TraceMessages = "";
window.Tracing.OutputMessages = "";
