Abstract
A cyclone outlet assembly with a frusto-conical dirt blocking plate minimizes clogging at the outlet of the cyclone separator. An upright vacuum cleaner with a cyclone separator is mounted on and in fluid communication with an elongated rigid tube that forms part of a working air conduit and also forms part of an upright handle that is pivotally mounted to a base module with a suction nozzle upstream from a conventional bag filter in a dirty air or clean air dust collection vacuum cleaner.
