If I told you I had invented and built a protor type pole that does not have and does not need a hose or tubing? it has a built in flow control and has the facilities for a portable water function,
Now if you have difficult access restrictions, were you have trouble getting your hose or even a backpack to the rear of a property, then this pole is the answer, if you have to go through customers homes with hoses or backpacks along with your poles, then again this pole is the answer, you can work on these propertys with ease with no trailing hoses at your feet, but pure water is still being pumped upto the windows
ok the pole has no hose running through it but you still need to connect the pole to your pump with what ? a hose this hose is still going to have to be taken through a customers house or layed on the ground ner your feet. unless you are saying that the pole can be disconected from the hose for short periods and still maintain a flow from the brush, if so well done to you.
