hi guys, been doing a lot of houses with gutter vac. the only problem i find is when there are big pieces of broken tile in gutter. how do you get them out? also some jobs you go to quote there are literally plants, grass and all sorts growing in them. other than get a cherry picker its impossible to get that out with a vac. do you just tell the custy you cant get big pieces of tile out? also is it worth training to use a cherry picker and hiring them for commercial gutters?
