this well-made dust collector for the Bosch Table see appear to be make of nylon and cotton and attach to the dust port at the rear of the saw . it have a zippered bottom , and do collect sawdust . it be not as good as connect to a shop vac but even with a shop vac you will still have sawdust to pick up -- with any make of `` job-site '' saw . I frequently use my saw in a garage so I use the dust collector and I also place a cardboard box under the saw . a great deal of the sawdust go into the box , quite a bit go into the Bosch dust collector , and a goodly amount will still be all over the floor . this be the way with all saw of this type . the price be great $ 10.99 , and I order it with a saw thus avoid any shipping fee or sale tax . I do recommend this accessory as it be a help . I order it on January 30 , with a delivery date on or before February 14 . I receive it before February 10 . it be well-packed . I be more than happy with Amazon and Bosch .
