Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
114 words
A gutter and roof cleaning nozzle system for use with wet/dry vacuum devices comprising: an integral nozzle manifold; a special purpose nozzle head operatively connected to one end of said manifold whereby debris and other foreign matter can be readily contacted; a continuous, non-telescoping flexible hose means operatively connected at one end to the end of said manifold opposite said nozzle head and at its other end to the wet/dry vacuum source to allow for passage of debris therebetween; and an elongated telescopic handle means supportingly attached to said manifold to allow the height of the nozzle above the ground to be adjusted and the same can be manipulated into operative debris removing position.
Claim 2
Dependent Claim
114 words

Claim 3
Dependent Claim
11 words
The system of claim 1 wherein the manifold is generally U-shaped.
Claim 4
Dependent Claim
21 words
