Abstract: The present disclosure relates to a pad surface cleaning system to be used with a conditioning module to condition a polishing surface of a polishing pad. The pad surface cleaning system may be used to spray the polishing surface with a high-pressure fluid spray to loosen debris from the polishing surface. The pad surface cleaning system may also be used to remove the loosened debris. Further, the pad surface cleaning system may isolate a conditioning disk from a polishing fluid to protect the conditioning disk from reacting with the polishing fluid.
