Why not use a ladder stabilizer? Even with the folding/articulating ladders the Werner quickclick stabilizer (one of the most popular and easiest to take on/off in seconds) still fits and locks in. Then you can rest the ladder anywhere and not damage the gutters. Plus it's SO much safer, your ladder won't budge.
Thanks for the video man. I do gutter cleaning with a gutter vac. It takes me about 2 to 3 hours to do a standard residential home (200ft of eavestrough). I like the idea of using a leaf blower, but it looks a bit messy. If you include the fact that you have to do a bit of a cleanup on the ground when using the leaf blower, I wonder which option would be more effective in the long run (vac or leaf blower?l
Leaf blower is crazy fast and effective. The only downside is there’s more risk involved and a mess to clean up, but the clean up is super quick. I just blow everything into surrounding planters. 200 linear ft of gutter will only take me around an hour and a half to clear and flush.
