- The thing is very useful. Launched and left, when finished - will report in the application. In general, the head does not hurt for cleaning dust from the floors. - draws maps, displays in the application, goes around the whole apartment, climbs under obstacles, does not hit anything - Through the application (everyone advises using Xiami, not Roborock), you can quite easily set cleaning zones, etc. It is convenient to launch and monitor remotely when, say, we are walking with our son - With a sink of floors business is a little differently. I would like, of course, a more advanced floor cleaning (with active rotating brushes) and the definition of surface types. But, at the time of purchase, there were no such advanced models in wide sale (at the time of writing this review, there are). Therefore, not a minus, but rather a note. But this is not enough in everyday life) For the floor washing system in this model (and in the vast majority of similar ones) on dark floors will only give the impression of "smearing" dust. On motley ones, like mine, everything is quite good (at least outwardly =-)) In general, the sink is not very good, but I won’t reduce the overall rating: at first I didn’t have a soul in it - only then I began to “sort through”)) PS. On the farm, all the same, I still use a cyclone-type battery vacuum cleaner, since it is still a little more powerful. In particular, when you need to point clean under the table after your son or on the balcony. Well, in the car, but that's another story.
