Once did a gutter clear on a bungalow in the middle of a dry summer. Used the vac and it was a nightmare, dust everywhere. Ended up just using the ladder and it was quicker and far easier. Today I cleared one with grass growing out of the full length of back gutter. The customers were saying that it will be hard with all the grass in it. I told them it will be fairly easy because its been so hot it will have shrunk. The moment I got hold of a big clump the whole lot nearly came out. They were pretty upset that I made it look so easy because nothing was holding the roots in place and it was dry as a bone. I reckon it would have took me three times longer with the vac.
