FWIW - use of zoom lenses will sometimes pull in dust from the outside and send it into the sensor cavity of the camera. Zooming the lens in and out are a bellows basically, so not changing a lens will not always prevent dust particles from entering the camera. Some zooms will pull more air in and out of the camera.
I have been shooting with a Nikon D7100 for several years now, change lenses often, and do not get much dust on the sensor. I set the camera to clean off the sensor at power on and power off, always making sure to hold the camera in the proper position so any dust shaken off falls down to the catch area.
I have not needed a "wet cleaning" yet, every now and then I will use a rocket blower to clear the sensor and the blower and lens brush to clear the lenses.
I will also remove spots in post processing easily until it looks like the time is right for a cleaning session with the rocket blower ;)

i also have the d7100 and the d810 ..use them all the time and so far have not had any spots or issues with these .if and when i change the lens i use a blower also as shown by a nikon tech...but unfortunately i have had spots twice now with the d7000s which i hardly used ..so they are packed up for now since i've been spoiled using the newer ones.
