Can I use Kärcher nozzles with my AVA?

Yes, most likely!

AVA is supplied with a quick coupling very similar to Kärcher's well-known coupling (K-series as it is sometimes known) which has been used on consumer models for over 20 years. The goal for the quick coupling that AVA has made was that it should be the market's easiest to use, and feel more stable than other solutions. In addition, we have made a locking ring that can be used. When you screw this down, the accessory sits even more firmly into the end of the lance or gun, which we believe gives you as a user a better and safer washing experience. Remember that the locking ring should only be screwed into place enough to stop the nozzle falling out, not tightened so much that you cannot get it undone again!

Our quick coupling therefore fits interchangeably with Kärcher's coupling, which means that you can go both ways, and use Kärcher on the AVA and AVA on the Kärcher.
