I bought a sky vac about a month ago and have used it six times. So far I'm very impressed. The carbon poles weigh nothing, almost.
The first three jobs I checked afterwards with a ladder and it did it's job. I only wished I'd bought the camera at the same time.
I've always done gutter clearing using ladders but now I feel like when I first went over to using wfp from being trad as in 'why didn't I use this before now'.
The first two jobs and having watched the videos on youtube were still a bit of a learning curve. The last job I did this week, piece of cake. It's like most things, it takes a bit of getting used to what works best and what doesn't.
