A:AnswerYou have to plug the robot in to charge. Once there is enough juice in the robot the app will be able to discover the robot under the same wifi. Then just follow instructions on app.
A:AnswerIt is capable of building more than one map, so you can move it upstairs and down, but you should probably move the base with it, so it can empty.
