I received this awesome product in exchange for an honest review from influenster. It works great and the noise level is almost none. It does require you to download an app for it called iRobot, then you set it up yourself according to instruction booklet that comes with the robot vaccum. You control the robot with your phone.  Very easy to use and is easily charged. It does require you to allow ot to map your house first then you can name each room of your house and save it on your phone. No matter where you are just instruct the robot to go and clean the whole house or just a specific room/area, you actually see the robot working in the room/ area and once done you can dock it back to its place. Once back in place it empties itself automatically to its attached bin. I haven't tried the mop option yet but will try soon. I love it and I am very excited about it. By the way I named mine as Raju. Lol.
