Anyone thought of incorporating a spike on the back of the looped head? Flip the pole to rake then flip back to suck what do you reckon?
I use the spike in a few different ways -on its side, straight in and pull etc, so Im not sure fixing it to the guttervac tubing / pole / head would help as it would limit movement. Also it would add weight. I like the spike on a separate pole too so if you have a mate, he can rake and you can vac.
Its an idea, give it a go and let us know how it went
