Thanks useful information: 
I had a few specks of dust starting to appear on my images at f/11, so I thought it might be time to get a sensor clean done. On pickup, I was shown before and after images and told there were a couple of spots that couldn't be removed. When I got home I took the attached image at f/22. At f/11, I can no longer see any dust particles, which is better than before, but my expectation was to come home with a truly clean sensor.
A question for those who have had sensor cleans done:
Was it unrealistic of me to expect a 100% clean sensor for $160? (ie, is it normal to be told some particles could not be removed?)
