ok i have made the prototype automatic pole hose cleaner, took it out on a test drive today, it was a success, brilliant, kept the tubing clean, no dirt passed up into my pole, and it was damp today, my hose was on wet soil, sawdus,t from decking grass, mud, it kept everything retained, this is only the first day, i will give it a week or 2 , if all goes well then i will have them made,
