Abstract: A cleaning device includes: a treatment container; a workpiece carrier arranged in the treatment container and configured to hold at least one workpiece; at least one nozzle configured to discharge a cleaning jet directed onto the workpiece carrier and mounted such that the at least one nozzle is moveable on a circulation track about the workpiece carrier and is pivotable about a pivoting axis extending parallel to an axis of rotation of the workpiece carrier; a pivoting device configured to pivot the at least one nozzle; and a controller configured to control a circulating movement of the at least one nozzle on the circulation track and a pivoting movement of the at least one nozzle, such that a specified point on a surface of the workpiece is impacted repeatedly by the cleaning jet at a respectively different angle, within a specified timeframe.

Abstract: A method for cleaning at least one workpiece and a cleaning device are described. The method includes: cleaning at least one workpiece held by a workpiece carrier in a treatment container, by at least one nozzle which discharges a cleaning jet directed onto the workpiece. The cleaning includes: specifying a rotational speed of the workpiece carrier and a circulation speed of the at least one nozzle on a circulation track about the workpiece carrier; rotating the workpiece carrier at the specified rotational speed; moving the at least one nozzle at the specified circulation speed about the workpiece carrier; and pivoting the at least one nozzle about a pivoting axis extending parallel to an axis of rotation of the workpiece carrier such that a specified point on a surface of the workpiece is impacted repeatedly by the cleaning jet at a respectively different angle, within a specified timeframe.
