Roborock Saros 20 Shows Error 53 on First Use and Needs Replacement

I purchased a Roborock Saros 20 robot vacuum cleaner from Teknosa and encountered an error during the very first use. The device immediately displayed error code 53 and has not been working properly since then. Since this problem occurred at first use, I have not contacted Roborock or Teknosa customer service yet. I do not currently have my invoice or order number with me, but I can provide it if needed during the process. Because a brand new product should not give an error from the first use, I request that my Roborock Saros 20 be replaced with a new and faultless device as soon as possible.
