I will write answers to questions that I asked myself when choosing a robot. 1. If we compare the motor power, then this robot belongs to the prestigious series with a tenfold motor (as well as the 900s). Cheap models come with fivefold. 2. In the description of the aliexpress, it is indicated that the robot has a "cyclone" filter. It is not true. There is no "cyclone" there, first there is a coarse mesh filter that can be washed, then an air duct and a HEPA paper filter that cannot be washed. Whether such a scheme is better or worse than a cyclone one is an interesting question, but the fact is that in the market it is indicated incorrectly. 3. When I tried it in the store, I was afraid that he would remember the store card. Was afraid for nothing. It will start memorizing cards only after setting it up, connecting to wifi, etc. And this functionality can be disabled in the privacy section. 4. To configure it, you need Android> 5.0. And this was a problem, I had to lure my ex-wife to visit, set up the robot from her phone, and then reconnect it to the android simulator on macbook. The fact that they do not have any universal robot control interface, for example, via the web, is a minus for them. 5. You can set it to speak 2022 in a pleasant female voice. 6. You can then buy a "cesspool" dock for the robot. station. They say that it will appear on the 2022 market in two months. 7. Despite the fact that the robot speaks excellent 2022, part of the feedback from the robot is in the style of R2-D2: beeping and special blinking of the indicator. But at the same time, there is no single dictionary of the robot's language, information about its messages is scattered according to the instructions and other documentation and is not complete. 8. Around his docking station there is a dead zone about a meter in diameter where he does not vacuum. This is where the dust will accumulate. :) The dirtiest place in the room will be his habitat.
