The WOLF VAC 3s is similar to the Wolf Vac 3 in every aspect.  The difference is the Separator. 

The Wolf Vac 3s comes equipped with a Separator that catches dust and debris before it hits your main filter in the vacuum. Both the separator and the Vacuum are equipped with bags to continually collect dust.  The Separator saves you time and wear and tear on your main filter.
