Hi Shina,
Yes, thats one of the reasons i designed aqua-dapter.
When i was window cleaning i thought theres got to be something easier than keep picking a on/off valve off the floor to turn the water off between windows, in most cases i couldnt be bothered in the end to put pole down to turn water off, so i tried taping it to my pole, but had big loop of hose keep twisting up really annoying.
So i believe that using aqua-dapter is a much more convenient way to control your water supply.
Steve.
