I made a shop vacuum cart for a couple of main reasons. The twenty foot hose is very nice, and the Dust Deputy cyclone separator which put almost all of the dirt and shavings into the barrel, and keeps the shop vac clean, and more importantly the filter stays pristine. A clean filter keeps the suction at a maximum. I’ve been using the shop a lot more, and even though I have dust collection to all the main tools, the planer and jointer still can spit out quite a bit of shavings onto the floor, so I’ll be using the shop vac cart quite a bit. The 20 gallon drum makes it so I won’t have to empty that so often, as the shavings add up to quite a bit.
