ABSTRACT:
A vacuum-type cleaning apparatus and a cleaning method employ a cleaning head which is mounted on a housing 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 transmitted via a suction channel through the intake opening and thereby to the object. Nozzles inject a stream of cleansing fluid into the channel and its flow is directed towards the intake opening and at 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 contaminant particles prior to contact being made by the stream of cleaning fluid in the wet cleaning zone.
