Because I hadn't noticed that the question was full of mistakes and therefore a bit incomprehensible... Hello! We are happy with the device. But we don't have wifi, is there any way we can still use the app? Or is that a prerequisite? Since we don't have the app, we have now sometimes locked the robot in the room that should be cleaned and then let it go "home". My friend thinks this damages the logarithm. Is this true? Thanks! Caro
