I used this tool for the first time yesterday. It worked very well but be prepared to get super dirty and covered in gutter muck. I was covered from head to toe in dirt. It did clean the gutters for sure 100% but because it blast it right out of the gutter and onto you and the ground I had to change heads to clean outside of gutter/side of house and ground walkway from all the blasted sand and dirt of the gutter. if this had a blast shield on top of the cone area it would be helpful...
works great with my spx3000. Be careful though, first time i stuck it in the gutter and pulled the trigger, gutter debris went flyin!! Once you get the right angle of dangle, works like a champ!!
