The tower is 170mm was exactly what the standard nozzle of 280mm was missing. You can now bring small items just shine. The essay I can now, for example, smaller mirror collector showcases television picture frame and lattice windows get super clean. The normal nozzle is this just too powerful. I was really glad that I have this narrow nozzle and found they had directly ordered. So I am very very very happy and would never want to miss. For those with a Kärcher Fetersauger a MUST !!!!
