An elongated tubular member having a valved coupling at one end to a garden hose, has an inverted J-shaped portion at its other end terminating in a hollow, paddle-like cleaning head. A user at ground level is thus enabled to extend the device into a rain gutter, and move it therealong to dislodge leaves and other debris. Water forced into the head is discharged at high velocity through small openings in the leading surface of the head, along paths calculated to aid in the dislodgement and flushing of the debris from the rain gutter. The tubular member can be sectionally constructed, so as to be extendable to selected, different lengths. The cleaning head is detachable, to permit the substitution of various cleaning heads, including, for example, a cleaning head having a plastic or rubber, resiliently deformable scraping edge, or one having a cleaning brush upon the debris-engaging edge of the head.

A device for cleaning rain gutters or the like, comprising: (a) an elongated, tubular rigid pole including valve means at one end for connecting the same to a garden hose or the like, thereby to permit water under pressure to be forced through the pole; (b) a rigid, tubular, cleaning head support portion detachably connected to the other end of the pole in communication therewith; and (c) a cleaning head detachably connected to the head support portion, said cleaning head being of hollow formation whereby water forced through the pole and communicating head support portion will be directed under pressure into the cleaning head, the cleaning head having forward and rear walls converging downwardly and including nozzle openings arranged for directing streams of water under pressure against debris lodged within the gutter, said cleaning head having a wiping edge at the convergent ends of the forward and rear walls below but in close proximity to the nozzle openings, whereby to exert a cutting action through the debris in close proximity to the area of said debris against which the streams forcibly discharged from the nozzles are directed, at least the wiping edge being of flexible materials, the cleaning head being inclined forwardly in a direction from the upper to the lower end thereof, said openings comprising a plurality of first openings and a plurality of second openings, the second openings being disposed between the wiping edge of the cleaning head and the first openings, the first openings being arranged to discharge water against the debris at an angle different from the angle at which the jet streams are discharged through the second openings, the angularity of the upper and lower openings being selected so as to cause the jet streams to be discharged therefrom along converging paths, the converging paths of the jet streams both extending downwardly in a direction forwardly of the cleaning head, so as to impact the debris at a location in close proximity to the bottom of the gutter, whereby to facilitate cutting of the debris loose from the gutter, by the cleaning head.
