We know: You’ve seen dozens of not-inexpensive dust collection vacs, and if you can’t afford one, you’ve probably managed to throw your own together with an auto switch and shop vacuum. So why tell you about this new one from DeWalt? Answer: It cleans its own filters.
Every 15 seconds, this vac pushes a pulse of air back through the filter to dislodge any dust buildup. Theoretically this lets you keep on cuttin’ (or sandin’ or…) without stopping to bang on the filter. Besides auto-clean, it’s a standard, pretty powerful vac, delivering 129 CFM via a 9 A motor. It weighs in at 32 lbs, and DeWalt claims the filters are 99% efficient. (We note the absence of the word HEPA, but then again your home-built solution isn’t HEPA certified, either.)
Expect to shell out around $550 for one.
