What you got there, Is a Frizea...Spelling wrong im sure but hopefully you get the idea,
Its the old style of shags just change them a little and change the name same stuff...
Yor right the Greenhorn wand the jets just bury beneth the fibers and you cant get the top clean, The Rx should be ok, I used it before on this stuff, with the jet extenders or ball valves on the green horn make it too long to clean this stuff,
you can take the stock recoil wand, and this will also work, Jets are just alot higher, Its a pain I know to clean this stuff,
I see alot of it down here, Looked at one yesterday, other than that it cleans up pretty nice, But of course its nylon, suck it up and deal with it, lolololololol
You can remove the ball valves off the greenhorn to clean it, then you have the drips to deal with as well, which stinks, Been there and tried that, Or just throw the Rx at it, Or carry another wand just for this.....
Two of the three stink....lol Best of luck
