When it comes to cost performance, Xiaomi is cheaper and Haier is slightly more expensive, but the cost performance can't just depend on the price, but also on the service life and experience. Comprehensive comparison, Haier's scene ecology is more worth buying. For example, in the smart kitchen scene, many people will struggle with what to eat today. In the smart kitchen, the smart refrigerator will actively recommend healthy recipes according to users' preferences. If you can't, you can also ask the specific method of smart refrigerator recipes by voice. You don't have to go out to buy food if you are short of food. It can be purchased with one click through the smart refrigerator, and the information of ingredients can be viewed at any time. After eating and drinking enough, put bowls, chopsticks, pots and pans into the dishwasher, and the voice can be turned on, saving time and effort. Of course, the above is just my personal opinion. If the landlord wants to buy it, it is still recommended to go to the offline experience center. After all, which one is more worth buying and which one is more suitable for your own needs will only be known after your own personal experience.
