I have thought long and hard about the problem of removing weeds from gutters, especially those weeds with a large root ball formed hard under overhanging tiles.
I've had an idea to solve the problem and did this today. As you can see, Alex is busy on the computer while I was fiddling around with a new "invention" of mine on a small piece of gutter and downpipe I have set up in our unit.
Alex takes no notice (he is used to my messing about) but was as shocked as me at the results of my meddling.
I jammed some weeds hard under an overhang which could not be budged by an 1800 watt vac. How hard I jammed them, no vac could have moved them. But watch what happened. I believe we are to something game changing. It removes weeds in seconds, a quick vac and the job is done.
