Don't waste your money. It's clear from the picture that the debri is lightweight and dry. Clearly staged. Gunk that gets in your gutter will be wet and heavy like I had today.
Many of these home improvement ads are staged. Not nearly the way you'd encounter things in real life.
This device will spray everywhere and you'll be soaked in no time.
I like this device but it will take some practice using it.
No device will get things completely clean but I just want to keep the water flowing when it rains.
