Warning: The nozzle is not the one shown in the photo. The one I received is pierced on the front and more pointed shape. This may be boring for some configuration but this time the drain cleaner does not advance alone (or almost) with the drain cleaner Karcher and brass nozzle. Another negative point: the adapter that fits well on my "old" karcher does not remain in place for running too easily and detaches of my spear. So if you were to use it every day take the other brand;) For the occasional AC not working too bad.
