Its an upgrade for us. I've tried gutter zap, gutter grenade, wild cherry, everything has been great somedays, not so great on others. I hate the marx off gutter brush, cause I can't get the pad to stay on there and I end up get an eye full of caustic soap as I'm flopping it around. Also, 75% of the time our normal hw gets em clean so I hate charging for people when I don't know if it will be necessary or not. For the pole we have just used a 3 section twist lock, I think its a mr longarm.
has anyone tried a water fed pole for gutter whitening? I thought its be cool to have something really light that can also feed the chem up there.
