Roborock S8 MaxV Ultra Failed Me - I Want a Full Refund

After using the Roborock S8 MaxV Ultra model without any issues for about three months, I started experiencing serious problems. During every cleaning, I receive a “mop stuck” error, and the mop does not lift. In addition, the device frequently loses its Wi-Fi connection. I purchased the product in cash with insurance for ₺74,000 from the Izmir Gaziemir Optimum AVM Media Markt store (Order No: 3VA2024000060364). After the problems began, I delivered the product to Media Markt, and it was sent to Roborock service. Although the service reported it as “repaired,” I had clearly requested a refund from the very beginning, both in-store and over the phone. Despite this, Media Markt staff said they would proceed based on the service decision. Roborock service prepared a report citing “hair and fur entrapment,” but I absolutely reject this explanation. I specifically purchased this device to clean hair and similar debris at home; I don’t expect it to vacuum thin air. Even though my product is under both warranty and insurance, I do not accept repair as a solution to these problems. I demand a full refund as soon as possible. I have also filed a complaint with the Consumer Arbitration Committee, and if necessary, I will escalate the matter through legal action in court.
