The Nilfisk equivalent of the Kärcher adapter: Click&Clean to M22 female.
Read the gender
M22 exists as male and female, and adapters are sold in both. The direction you need is decided by the accessory you already own — if it terminates in a male thread, you need female here. It is the most common mistake in this family, and the photographs do not help.
The same discipline
One adapter, rated above peak pressure, fully seated, checked for weeping. And where the accessory exists in Nilfisk’s native fitting, that is the version to buy.
Availability
No such listing: the American Amazon shop answers the reference with a search box rather than a page.

The questions we hear
Male or female — how do I tell what I need?
Look at the accessory, not the machine. If the accessory ends in a male thread, you need an adapter that presents a female one, and vice versa. Half the returns in this category are the right adapter in the wrong gender, because the photographs look identical.
