The Kärcher K Mini is compatible with various Kärcher accessories, but specific information about compatibility with the pipe cleaning kit is not explicitly mentioned in the sources provided.

However, it is known that the K Mini is compatible with the Kärcher K 2 range of accessories, which includes a wide range of accessories.

To ensure that the drain cleaning kit is compatible, I recommend checking the specific connections and compatibility information on the official Kärcher website or in the instruction manuals of the K Mini and the drain cleaning kit. If you need further help, you can also contact Kärcher customer service.
