I've had my little Oreck vacuum for the truck for a while now. And it's not bad, always wished it had a little more suction. Use it for cleaning up floors, the insides of cabinets and on my belt sander when I am scribing cabinets. The bag is pretty small but then again, so isn't the vacuum. I figure it has about 65 CFM. Works great on floors but doesn't have much pull in cabinets, you have to be right on the dust. Works well enough for the belt sander.
Made a small box for it in the truck and it fits in snug and doesn't take up much room which was the number 1 reason for the choice.
I've kept an eye out for small vacuums and came across the Metro line for car detailers. Just a bit bigger than my Oreck and much more powerful. 130CFM which is about what the Festool vac pull. Plus 95 inch of water so it can keep going when the bag gets near full.
Came with a bunch of tools, more than I've shown here. Has a little 4 wheeled dolly that I likely won't be using mostly to keep it compact. Since my Oreck tools work with the Metro and I have them fit to the truck setup I'll be using the Oreck tools. The wand is retractable and the floor tool has more metal in it.
I had to make a new box because it's taller by 2" and the hose ports stick out instead of in. Took about an hour to make/modify and it all fits nice. Best thing is I still get to keep my Milwaukee Rocket Light in that compartment of the truck. I was a bit worried because it was already a tight fit.
So we'll see how this one works out. The vacuum is all metal and made in the US. Cost about $280 which is about $200 more than the Oreck. It's pretty quiet, not as quiet as my Fein, but way more quiet than my Ridgid. Not sure you could use it on a tablesaw only because the bag is small. Same with a chopsaw, but that would be more feasible.
