Basically, the gutter cleaning wand is a u shaped tube with 1/4 inch quick couplers on either end. Hook it to the end of your wand and put the nozzle in the other end and go to town. You will certainly clean your gutters and what ever comes out will be either on you, the house or the ground. You can use an extension wand to give you more height. I personally have a not so steep roof and normally get my back pack blower and walk the roof to clean the gutters. that worked well for me,,,,,,,,,,,,,and I am in the pressure washing business. The gutter cleaners work fine,,,,,,,,,,,,,,,but me,,,,,,,,,,,I had my trees cut down
