My first smart tech. And I got used to it easily. The vacuum cleaner is controlled directly from the smartphone. This is convenient in the sense that the remote control is not lost. He can be asked to clean a particular area or the whole room. In space, he is perfectly oriented, does not slow down when the chairs stand differently. The cleaning quality is excellent. The vacuum cleaner, apparently, determines the type of surface and contamination. Therefore, where there is a lot of garbage, it works longer, sometimes it increases power - you can hear it by the sound. Moreover, these changes occur automatically not without the need to send a command. It up everything - both dust particles and pieces of paper. A useful accessory is the side brush, thanks to which dust is removed from the skirting boards. Is that it remains quite a bit in the corners.
