Power Washing and Roof Cleaning Forum

You could add a swivel goose neck on the Gardiner if you think it would make it easier.
Here's the swivel form their site - swivel goose neck  it will thread onto the pole or this one fits in the end

For cleaning gutters I'd recommend the sill brush for best coverage 

I think Dwight at J Racenstein can help you find the set up to work on the pole for roof cleaning.
