I Face Repeated Malfunction With Tefal X-Force Flex 14.80 Aqua Vacuum

I purchased a Tefal X-Force Flex 14.80 Aqua vacuum cleaner from the Media Markt Gaziantep Forum AVM store, paying around ₺27,500. Since the very first uses, the device has consistently shut itself off when used on the third power level, showing an “eco” warning.

Even after cleaning and maintaining the product as instructed, the problem did not go away. I sent it in under warranty, but when it came back from service, the exact same issue happened on the first use. I also shared the problem with store staff, yet no permanent solution was provided.

This recurring defect has caused both financial loss and major inconvenience. I expect Media Markt to take full responsibility and either replace my vacuum with a brand-new unit or issue a full refund. I do not accept temporary fixes for a product that fails repeatedly.

Service number: T03050085-R-C.
I request that my grievance be resolved urgently and fairly.
