I have a Canon 7D mk1. This camera has a automated cleaning setting. Someone explained me the sensor has some kind of special coating that can be damaged when using fluid based cleaning. Something that was never a problem for my older 30D and 10D which of course do not have the automated cleaning.
In fairnes though, the 7D's cleaning feature works brilliantly. Even after taking it into a sand pit with helicopters flying around I had no noticable dust spots! And that's with the infamous 100-400L dustpump!
