Hi guys, I live in an apartment with a very dusty carpet (I have to vacuum once a week because it is that bad). Given the fact that the fans of the RMBP work somehow like a vacuum too I was wondering if anybody had made the same experience and already cleaned them. So, how easy is it to clean them and how often do you clean them? Is there a way how I could check if need to clean them without opening the machine? Thx.
