The product "250 m TCCA corded robotic lawnmower" from Wiltec, with product code "61050", is an accessory for garden machinery. However, there is no specific information indicating its compatibility with Parkside robot lawnmowers.
To determine whether it works with Parkside robots, I recommend contacting the manufacturer Wiltec directly or checking the product specifications to see if they mention compatibility with specific brands. In addition, you could also contact Parkside customer service to ask about the compatibility of their products with third-party accessories.
