The adjusting head.. I use it all the time and thank you for pointing that out, depending on how close I am working to the building I will angle it out.. Defo over connie roof.
The guttercleaningsystem poles are well thought out and each nozzle is locked in place preventing damage to you and people's property..
As for nozzles I do use even that super skinny one from time to time if roof tiles are to far over hanging, always expect the unexpected cause there will be a time you might need it..
Weed hook works a treat as I've already pointed out,..yes the bigger the vac the better but I was on a budget so only have 1400w vac and works without a problem.
