Our Skyvac 85 works fine with pine needles, both the long ones and the short ones. There might be other types of gunk mixed in with the pine needles where those users ate saying they don’t work with a Skyvac.
I have learned over the years that there can be a lot of local variation for operating conditions.
Has anyone successfully used a gutter vac at 4 storeys or even 5 storeys? I’m considering getting the Skyvac Interceptor but most people only seem to use it for 2 storeys?
