This iRobot vacuum/mop is really a useful cleaning tool to have in your home. The initial setup was very easy right out of the box. After downloading the app, my vacuum got to work mapping my house. It took quite some time, but it eventually got a full map. I sent it off to do it's first sweep, and it did a very good job. There were some crumbs left behind, but it really got a lot. When it goes back to the charging station, it empties itself. I think that is wonderful, but it is VERY loud. It would definitely wake up my kids at night, so I am not able to run this at night. I typically run it during the day when nobody is home.
