but free sensor cleaning is "fast-pace" job right? so it is actual not so clean?
someone said this before right?

Maybe should say, due to many people send in, they need to do it quickly, if not, later too many DSLR pending for cleaning.
The process is the same, just whether they have more time to do in detail and properly. Just like you go service your car, if you go when there is a lot of car, they will be doing it quickly, when there's no car, the mechanic can pay more attention to detail (also depend on the mechanic "lar").
As said, it also depend on the person doing the job; Doing it "fast" doesn't mean bad, if the person is good, does a great job, fast and efficient, then fast doesn't mean will end up bad.
