Well done peter with your Auto brush.
I think I will stick to my Flow control valves on each of my pole hoses. I have had these fitted for years now and do not waste any water, or find myself rushing. Also peter I personally find when scrubbibg hard that i knock the brush head from side to side on the window frame this would turn the head off and I would have to turn it on again. But for those with no other method of controlling flow (other than pinching!!!!!!) it seems like an interesting solution. How hard did you find the Patenting Process?
Ben-Chan, you need more than one pole, doing all this adjusting and taking sections off and fitting new hose just wastes time, a few years a ago we bought a Powerpole with the idea that we could remove sections, but we found it such a hassle that we left it as 4 sections and the rest stayed in the roof of the garage and we used our larger poles instead, we have since sold the powerpole because all of these twist grips were just too slow and fiddly! We have about 3-4 different poles sizes for each operator and just switch between them all, very quick and no hassle, also extends the life of each pole.
