A month and a half ago, my husband and I were presented with such a robot by friends for our anniversary - for which we thank them again! They also asked me to write a review in a month, which I do) I am writing from the bottom of my heart, I was not asked to write a positive review) So I still never cease to be amazed at this miracle of technology. It is very easy to use it, in principle, it does everything itself, except for the fact that it does not take the garbage into the garbage chute) From the first start it is clear that he memorizes the plan of the room. He collects everything in a row, well, if only something large or heavy enough for him like a pencil or a 10 coin, then he may not be able to collect it. I even checked, deliberately tered my hair around the room and began to observe. The vacuum cleaner collected absolutely everything. By the way, speaking of brushes, I noted the benefits of a side brush, thanks to which there is no dust left near the baseboard. Of course, I do not forget about cleaning the robot itself. After almost every cleaning, I clean its brushes and container, but if I don’t do this, then over time, the wound hair on the brush begins to spoil it - wipe it. And if you do not clean the filter, then, for obvious reasons, it becomes harder to it in. So you still have to put in some effort.
