As the title says. I know ladders are better, cheaper etc etc, but: 1. I'm not getting up ladders if I can help it and 2. Most of the jobs that I'm quoting for have awkward access that I wouldn't be able to use a ladder for anyway. I have enough jobs to pay for a vac, but I want to know if they really work. Whats the consensus? It seems some say they work and some say they don't. I'll get a 3000w vac and some cf poles. So its either the vacs work great I'll get one and do the jobs and everyones happy or of they don't work I won't get one and turn the jobs down. Whats everyones experience, do they really work?
