You know the more I read about that DC unit the more it sounds appealing and similar to the 2 I have. And like mine it takes bags which will prolong the life of the unit. Totally worth it in my opinion. Plus the ability to roll around. For instance, I'm taking a class right now for a large project build. Prior to me going to class I'm using my TS on the other side of my shop to break down sheet goods. I just roll the unit over, it provides power and it won't cost people an arm and a leg for the Festool, Bosch or Dewalt units which are similarly priced. The power unit Comp is using is also a much cheaper way of using the shop gave but this Karcher is viable too if you afraid of dust like me.
