I am thinking of getting one of these, but my pressure washer is not the correct fitting for it, and then one I really want also is not the correct fitment!

Can some sone post some pictures of the hose pipe version and what sort of foam this produces and if it is worth getting, so I can compare to the pressure washer version.

I want to use as a pre wash to loosen up the dirt before I start washing.

thanks,
Gav
