The Chinese version, because of this, for more or less "comfortable" control through the application, I need to stand right in front of the router, otherwise, even if I move 5-10 meters away, the application can think for a very long time or even give an error.
Some pros:
The price, size of the device, ease of setup and ease of use in general, cleans and wipes the floors well, even drives over ledges that are almost a centimeter larger than indicated in the specifications.
Different cons…
