It sucks! It blows! It is
revolting revolutionary!
I was at a car wash a couple of months ago and not only did they have vacuums, but compressed air, which was great, but the compressed air blew dust all over, and it was frustrating needing to coordinate them.
The last step before putting my engine back together was to blow out the cylinders and stuff. I could have bought a can, but I figured ít was time to purchase a compressor and a shop vacuum.
Had it worked I would have used epoxy. With the duct tape it still required two hands, but Home Depot's cheapest compressor was stronger than their cheapest vacuum, even though it was not the highest setting.
Home Depot's strongest vacuum has less than twice the horsepower than the one I bought, so I do not think you could just buy a stronger vacuum. You could turn down the compressor, but I am not sure it would get the job done.
Perhaps having a giant fan next to the car would blow out the dust.
Well, I tried.
