Review on Robot Vacuum Cleaner iRobot Roomba i7, black by Ada Lewandowska ᠌

The robot somewhere in the brain has a map with the layout of our apartment. He always knows exactly where he is. He can be given a separate task, for example, to clean only the kitchen and the corridor. He takes commands over Wifi, so he can be made to clean the rooms via the Internet even before we return home.
