You can use the wand at any length you want.
You will only be able to draw chemical thru it if it has a 3/8 hose (bigger then 1/4). Myself, I use an xjet to apply the chemical, then wash with the wand.
Good luck.
Also, when I lower the extension wand to the ground, I keep it on until it is six inches off the ground. The pressure breaks it's fall for you.
