And just to think I almost didn't click on this thread, assuming it was some trick click bait "what is 3+5?" type question that one would naturally assume was "8" but due to some newfangled common core snowflake math came out to "whatever you want it to be."
Fwiw, they have leafblower attachments premade for just such a task. I bought one.
It wasn't worth a darn. There was too much length, not enough leverage, for whatever reason, it didn't work for me.
I have included two pictures- one of my leafblower system, and the gutter to show you how much I like it.
Now I have TWO projects- one to throw out the leaf blower piping, and two, to clean out the gutters.
I hope your project* works better for you than it did for me!
*If you look closely, you can see that not only did I sqaunder $$$ on the project, I wasted precious duct tape and reinforcing trying to perfect the original concept. I lost an entire afternoon on this endeavor. Worse yet, neighbors might have seen me spinning around in circles with a silly leaf blower system blowing me around like some zany cartoon character, or those inflatable things with zany arms that you see flailing about in front of used car lots.
double edit- even if you are not looking for a system to clean the gutters from the ground but perhaps a shorter extension to let you stand on the roof and hit the gutters from above, the stuff still gets jammed under the gutter mounting nails and will not clean out well. Granted- I am cleaning out pine needles, so you might have better luck with real leaves. When I use a backpack mounted leaf blower- it is too much power to safely use while standing on steep inclines, and still gets jammed.
I have put extensive and exhaustive testing in pursuit of laziness. I wanted to share the results.
