I cashed in some credits to get this vac. My primary use is cleaning the dust out of my home computers. Pros: It says DeWalt on the side and I assumed that meant quality. I was mistaken. Cons: 1) short power cord, 2) short hose, and 3) I'm glad others have units that actually work, but mine can't even lift dustbunnies off the cooling vents of my computers. He airflow is so minimal that when the power is turned off, everything falls out of the hose. I've tried cleaning the internal motor and filter with no success. It does make a lot of noise, however. It 'sounds' like a vacuum, but doesn't work like one. I've used the DCV517M1 extensively at work and I dearly wish I had gotten that one instead.
