What is the self-cleaning feature on a Wolf oven?

The Wolf oven's self-cleaning mode is a feature that automatically cleans the oven in four hours time. According to Wolf, running a few self-clean sessions per year is enough to keep the oven clean.

The Wolf oven's self-cleaning mode utilizes temperatures of 900 degrees Fahrenheit to clean the interior surface. All oven racks and guides must be removed before self-cleaning. Because of the high temperatures, exterior surfaces get hotter than usual, so care must be taken. Smoke and burning smells are typical during a self-cleaning session. The amount of smoke released depends on how much food residue is in the oven prior to cleaning.
