Turns out, it's a pixel-remapping feature instead of a true dust
removal feature. Given the size of some dust particles, you are likely
going to have to clean as much as in the past, if you had to. From

Rich, for heaven's sake get some reading comprehension lessons, or at
least do a *bit* of extra research before shooting off these silly
posts.

===============
Canon takes..a unified giant step forward with its new, TWO-TIERED dust
removal technology called the EOS Integrated Cleaning System...
Canon begins by minimizing the dust and particles created by the camera
itself..
Canon also treats the camera's low pass filter with an anti-static
charge..
..recognizing that humidity and a variety of real world conditions can
cause dust to enter and adhere to the sensor or low pass filter despite
the most scrupulous of efforts, CANON CREATED THE "SELF CLEANING SENSOR
UNIT". The low pass filter on the front of the CMOS sensor is attached
to an ULTRASONIC VIBRATING UNIT that literally SHAKES THE LOOSE DUST
PARTICLES OFF the surface.
===============
and here's where your daft post comes in...
===============
.. there are occasions when dust particles of a stickier nature are NOT
vibrated free of the low pass filter. IN THESE SITUATIONS, the Dust
Delete Data function can be engaged. Simply put, by aiming the camera
at a white wall or even a white piece of paper (or, in a pinch,
removing the lens from the camera) the Dust Delete Data function will
map the size and position of the dust particles remaining on the low
pass filter.
===============
Sigh.

Who cares? I have a tank of nitrogen that'll blow any Canon dust removal
system away.

Is is "dry" nitrogen?

Absolutely! Only the best goes into my Nikons. The 85mm f/1.4 loves it,
can you see it smiling?
