Sensor cleaning

Hi all,
My camera is the mark5dIII.
A few weeks ago I noticed a red (hot) pixel. I searched on the net and found a way to remove it. I used the manual sensor cleaning option and it worked. I enabled the automatic sensor cleaning option, but now, when I turn on the camera I have to wait for about 8-10 seconds, then the sensor cleaning starts and then it is possible to use the camera (liev view etc.).
Before the red pixel issue I turned on the camera and I could immediately use all functions. As always, when I turn off the camera the sensor cleaning starts again. That's all right of course.
Is it working the same way with your camera?
