When I first started doing housewashing, I bought a telescoping fiberglass pole. I absolutely hate the thing. The hose twists around inside the pole, which makes the nozzle point the wrong way, the trigger is in a very bad position ergonomically, etc. I have since switched over to a long wand made of aircraft aluminum (similar to the W-15 I guess). It is very light, more controllable, and I can use a more normal trigger gun position.
