We got a gutter vac this year as whenever I was asked to do gutter jobs I didn't want to go up a ladder as we are wfp , how can you bang on about safety with window cleaning then go up a ladder to do a gutter clean . What I would say is if your busy enough cleaning windows then don't worry about gutter cleaning the only reason i got one was there are now 2 of us so I'm not so busy cleaning windows Marc
