I love Oneida's Dust Deputy. It keeps my shop-vac filter clean and the suction super-strong. But bolted to the side of my vac, it is an awkward appendage. I fixed that problem for good with this simple shopmade cart that marries the two into one nimble unit.
You may have noticed the cloud of fine dust that blows out the exhaust when you turn on most shop vacuums. Small dust particles flow right through standard shop vacuum dust filters. To stop this fine dust, buy a high-quality HEPA filter from any store that sells your vacuum brand. They’re well worth the price because they last a long time and can be rinsed clean.
