Got the tornador black the other day and tried it out this weekend. I was pretty disappointed in the performance but I feel this is due to my compressor. It only produces 3.3cfm at 90psi and I know the black requires 4.5cfm. My question is does this difference in cfm really effect the performance that much. Truthfully I feel like this was just blowing air around, not really doing a deep clean. I could see no difference in cleaning results and dont feel it justified the 200 dollar purchase. I may be getting another compressor for stuff around the garage and might consider finding a higher cfm machine.
