I just figured that out on my own lol. Kind of disappointing. I read the manual again and it mentions if it's not misting properly than it could be too much water (despite my only putting in no more than 300ml heh). I poured some out (to about 250ml) and the mist is definitely stronger. No where near as strong as that youtube video, but strong enough that I can now smell the scent all throughout the room. So now I am much happier.
