ABSTRACT:
An apparatus for cleaning debris from ducts. The apparatus has a pair of rotatable jets with one of the jets having a zero orifice and the other jet having a spread orifice. A means supports the jets and fluid is supplied to them. Fluid leaving the jet having the zero orifice impinges the debris and cuts it from the duct and fluid leaving the other jet having the spread orifice produces a flushing action removing the debris after it has been cut from the duct.
