Pipelines use pigs to clean the pipeline. I propose the same for gutters, which could be described as half of a pipe. The pig would be dropped in the gutter and a cable attached to each end and draped to the ground like a window blind pull string. You would be able to pull the pig in both directions. The pig's shape would roughly assume the proportions of the gutter, and be small enough to fit under the gutter attaching nails. Each end of the pig would have a wedge cut. The wedge would angle outwards to force debris away from the structure and upwards to push the debris out of the gutter.-- Sunstone, Aug 21 2008 Pipeline pig pics http://images.googl...=1&um=1&sa=N&tab=wiPipeline cleaning pigs [Sunstone, Aug 21 2008] Minipig http://www.metro.co...e_id=34&expand=trueNo, not minifig - they're lego.
