I pick up this bag when I purchase the Bosch 4000 table saw . I be hope to avoid use a vaccuum attachment on the job site . I quickly find that if I be serious about contain saw dust , I have to ditch this collection bag . it collect maybe half the dust , if that . if you have the power to run both the saw and a vaccuum attachment , do it , and leave the bag for when you can work outside or you can unplug the saw and vaccuum up the mess .
