I love this attachment! I use it all the time and so happy Samsung came up with this this. This makes my vacuum an all in one complete solution for hard floors! Some people say it doesn't spray when they first get it. I've had no issues. Just fill up the container and press your plus button for a bit. It eventually will start spraying. Obviously it has to prime itself the first time. After you get it going it'll work instantly the next time you use it.
