Topic tags/keywords: shop vac dust extractor dust cobra

The existing 1987 Craftsman Shop Vac equipped with the Oneida Dust Deputy seems to be wearing out so it is time to consider a replacement. My options are to 1) buy another shop vac; cheap and easy, 2) buy a dust extractor and reuse the Dust Deputy separator; more expensive than the shop vac option, or 3) buy the Oneida Dust Cobra; the most expensive option whose performance for project and shop clean-up and handheld power tools is unclear to me.

My stationary tools are connected to a central dust collection system. Therefore, the shop vac replacement would be connected to the handheld router and random orbital sanders and perform project cleanup in preparation for finishing and general shop cleanup.

While the existing shop vac performs these tasks, greater suction would be appreciated. I would guess that a dust extractor equipped with a dust separator (Dust Deputy) would perform better than the shop vac. But I wonder whether, for a few hundred dollars more, the Dust Cobra would perform best.

Unfortunately I have found little in the way of product reviews for the Dust Cobra.

Any comments are appreciated, especially those from anyone who use the Dust Cobra.

it seems to me that there are a LOT more cost effective options between your #2 choice and your #3 choice.

I have a small shop, so I dont need the kind of setup you are after.

get as small a micron containment as you can afford, that’s always been my advice to anyone.

I find that dust collectors and shop vacuums serve different functions and each are needed in a woodworking shop.

Dust collectors are not portable and don’t always have greater vacuum power than a shop vac but do process larger volumes of air which pulls dust and small particles in from stationary tools. I find my shop vac indispensable for numerous uses like cleaning vehicles interior and particularly it’s ability to wet vacuum; a feature I use regularly to clean out the last few gallons of water in my hot tub that won’t go out the drain. I also frequently use the blower side of the shop vac…..sometimes I just open the big door on my shop and give it a good blowing out.

I can’t see that Oneida’s Dust Cobra would be any better than other cyclone based dust collectors so I would look at price and volume of air when making comparisons. The above comment about micron filtering is also important.
