Right up at the top of the features that I like about my Festool tools, is the great dust control that they (mostly) provide.
I say "mostly" because in some situations, I can't get adequate chip and dust control with my OF 1400 EQ-Plus router. More than one connector is provided to attach to the shop vac, but sometimes they are just not up to the job.
As an example, last night I was edge routing some door fronts (clamped to my bench) with the large bit shown in the following picture:

and the 'below the bit' connector was attached to my vacuum. I could not use the 'above the bit' connector because the bit was too wide.
As you can see in the following picture, very little was sucked up:
