From personal impressions. I am very satisfied! I have a large cat, so it has fur. Leaving for work - turn on. If I forgot, then at work I turn it on through the application. I return to a clean apartment, without wool and dust. I laugh out loud at those who say that he does not vacuum the corners. And he doesn’t close the doors to vacuum behind them and doesn’t move the sofas to remove dust from under them. I do this with a classic vacuum cleaner. Thanks to all those who invented, made and knows how to sell these robots! Thanks for helping with homework!
