So I finally broke down and bought a modern shop vac, a Bosch VAC090S. What a lovely machine; quiet, powerful, turns on when you turn the sander on, no plume of dust into the air when you turn it on, and as someone here noted, it even rolls over its own cord. What's not to like, one asks? The supplied hose and various fittings fit none of the attachments I already have, neither Sears, nor Shop-Vac, nor the humble home vacuum cleaner. OK, so they have some proprietary or metric fitting size, it's the way of the world to force you to buy new stuff. But what about my Bosch sander, the primary tool I will use it with? Does the Bosch hose on the Bosch sander connect to the Bosch vacuum? Not really. It's possible to put the two pieces together, but there is no friction fit nor mechanical link. The universal solution to "it moves and it's not supposed to"? Duct tape. Seems like a shame to have to kludge together such otherwise elegant parts. And here I selected against the Festool on the expectation that their parts wouldn't fit anything else. Perhaps the Bosch vac uses the Festool standard? Could this be an excuse for a whole shop full of new green tools?
