Dust Collection Cart
The cart is pretty basic and holds the shop vac on the bottom and the sawdust separator on top. The connectors detaches easily so I can quickly connect tools to it and the outlet strip gives me access to power when I need it. Now I don't find myself dragging along the separator, vac, power strip and tools separately and can roll them all to wherever I'm working.
Table Saw Cart
My workflow doesn't center around a table saw so I usually keep it on the side until I need to use it. That means having to find a place to set it up, plug it into the dust collector, and put up a out feed table to support the cut-off. By putting the saw on a cart with wheels, I can move it around easily. The area under the saw can hold saw accessories and the fold-up out feed table makes it more convenient then having a separate table.
I can how roll the two cart to where I'm going to use them and quickly connect the saw to the dust collector and start working!
