rich,
I can answer that. The gutter spike and other various attachment i.e camera connects to a different pole than the one used to vacuum. What i would suggest you do is purchase a 48ft power pole. You can use it for power washing and also the sections come apart so you can use them for camera and spike. Also a collet adaptor is an item that is put into pole to allow you to remove the top 3 sections making pole way lighter for power washing. Its a must buy.
Ps, I find if you want to find out something a phone call is the best way.
