I use it in 5 different rooms. I do move my kitchen chairs as it seems to want to go under them and when it does has a hard time escaping. Im a senior citizen and with the bending down to check the bag is a struggle. My husband got me this and at 85 years old I am not good with the technical part. I still have not scrubbed the floor as I don't understand how to do it. I will have to call the company. Also when it mapped the rooms out (our daughter helped put the app on my phone) it messed up and now I don't know how to remap it. I really want to use this and my husband gets a real charge out of it how it goes back "home"... I don't like it as I have to move the chairs in the kitchen and the dining room . I have bent down to check the bag and there is no dirt in it. Is my house that clean????? When one of the kids come over we will read the instructions or call you and hopefully I will like it better.. Thank You
