Karcher Variable Speed Vac?

[Strokes77]

So the Fein and the Festool vacs are awesome. But, in my opinion the things they do that set them apart are the auto start when you start the tool, and the variable speed.

This Karcher vacuum that is offered by Woodcraft for 199, or this amazon link has both of these features.

Does anyone have any experience with this thing?

I don't have that vac, though I recently bought a Nilfisk which is a European machine similar to the Fein and Festool vacs. I have one level above this machine Nilfisk but it is pretty much the same without a stainless tub. Has an electric tool start function and comes with a nice set of attachments, unlike some of the others.
