Price kept me away but preholiday demise of my old one led me to get this. Even tho it's a lot more than a big box store product, it's worth it! I'm glad I went for the corded/cordless version also. The versatility is great.
Don't get me wrong it runs just as good on battery power. I've used the 20v 5Ah & the 12v batteries. 12v is good for small jobs of the 1/2hr range. My 20v 5Ah got over an hour & I plugged the hose into my table saw instead of the bag. Awesome!
The hepa filter had to be cleaned before the container filled with fine dust or fine wood particles. To me that's ok, means it's working. Easy to clean filter. Just twist it off, shake, reinstall & go. No dust or debris going out the exhaust!
Now that I have it I can't say enough about it. Versatile, powerful, good working design. I read one reviewer that would like a battery charger when using the cord, I agree. That's the only negative I have to say. Although I am sorry I spent $40 on a big box shop vac p.o.s.! Thanks dewalt
