We decided to replace it with a Samsung Navibot Silencio, which we did. It served us well for ten years, but toward the end of its useful life, it started to develop a number of bugs, and after a few repairs, it almost completely stopped collecting garbage. My decision was influenced by the absence of a camera, the fact that the older robot had a very unsatisfactory reaction when riding under a black trampoline, and the presence of rubber brushes. Both features performed exceptionally well over a period of two weeks. There has not been a single day in which he has not moved across the entirety of the apartment (according to his own report in the application). I'm sure there were some unique features that Samsung had that we don't have here, but so far I enjoy everything, and I especially like that considerably less hair accumulates on all of the brushes. Because I find it to be too loud to use when there are people in the house, it is still preferable to use it when no one is there.
