CLEANING APPARATUS AND METHOD OF CLEANING Abstract of the Disclosure: A vacuum-type cleaning apparatus and A cleaning method employ n cleaning head which is mounted on a hous- ing and which has an intake opening that is adapted to be juxtaposed with contaminated portions of an object to be cleaned. A suction force is generated and trans- mitted via a suction channel through the intake opening and thereby to the object. Nozzles inject a stream of cleaning fluid into the channel and its flow is directed towards the intake opening and set an angle relative to the plane of the intake opening so as to impinge the object prior to the removal of the contaminants entrained in the stream from the object by suction. The flow is directed by a baffle which is inclined transversely of the plane of the intake opening, preferably at an acute angle. The baffle is mounted within the channel and provides for a dry cleaning zone to pick up loose con- taminant particles prior to contact being made by the stream of cleaning fluid in the wet cleaning zone. -2-
