choice I have the lance 24ft lance from northern tools and was going to combine it with the omnivac , the omnivac cleaning the gutters and the lance giving a final rinse, however after reading your post I will review this idea
I have seen the vacs on other sites for about £500, so might put something together myself .I just thought that the omnivac was good value for money as you were getting the powerpole along with the system
looks like a little research is needed, but thanks for posting as you have saved a few of us going down the same route.Maybe omnipole will look at this post and sort you out , start holding your breath
