ABSTRACT:
A portable vacuum cleaner contains within its housing a dust collecting part in front of a fan. A suction inlet is at the front end and the opening surface defined by it is nearly horizontal and either coplanar with or protruding below the bottom surface of the housing so that the accumulated dust will not fall out of the suction inlet when the fan is stopped.
