Hello Anita Grob
We use the parquet nozzle on various Kärcher hoovers, including a VC6 Premium. The parquet nozzle can be attached to all of them without any problems. However, the locking mechanism does not click into place. But that's not a problem. In addition, you can no longer attach the suction pipe to the hoover. We accept that too. In our opinion, vacuuming on parquet, laminate and stone floors is much more pleasant. The parquet nozzle literally glides over the floor. If you are also looking for this feature, I would risk buying the VC6300. I hope this information helps. Best regards Marcel Niederer
