Review on Robot vacuum cleaner Dreame F9 RU, white by Jnis Ginters ᠌

Different pros: It worked properly for two weeks, there were no questions, but then something went wrong Different cons: We bought a model from the Doctor Techno store. After two weeks, the vacuum cleaner stopped seeing the boundaries of the constructed map, as if it were traveling outdoors. When resetting the WiFi network and when resetting the settings, it cannot build a map, it drives randomly, and not s-shaped as indicated in the instructions. When contacting the xiaomi service center by phone, they said that the serial number is not 2022, therefore, it cannot be serviced at the official service center, which means that the product is not Certify. Very disappointing, I will issue a refund, I will supplement the review whether the money will be returned
