Roborock Q7 Max Fails to Navigate, Map, or Clean Properly Since Day One

I purchased the Roborock Q7 Max robot vacuum from the Istanbul Viaport MediaMarkt store on March 8, 2023, under contract number 01756.1079***. Since the day I brought it home, I’ve had non-stop issues. The device constantly gets confused, cannot locate its docking station, splits rooms into random sections, and frequently leaves the cleaning job unfinished. Worst of all, it fails to update its map after any changes to the room layout—even minor furniture adjustments.

Despite sending it to the service center twice, they simply returned it both times claiming “no problem was found,” without offering any real solution. This is unacceptable for a product at this price point and quality level.

I’m requesting a full resolution—either by replacing this defective vacuum with a new one or by issuing a full refund. I’ve already submitted visual evidence showing all the problems I’m facing. I expect Roborock and MediaMarkt to take this matter seriously and provide proper customer support, instead of repeatedly ignoring a clearly faulty product.
