Ridgid's Pro Pack is a winner in my book. I purchased this model 2 weeks ago specifically for detailing vehicles, I've used it on 2 vehicles (SUV and mid-sized sedan). I'm very pleased with its performance. I have not used this as a wet-vac yet, but its clear the unit won't hold anywhere near 4 gallons of water.. and this is the only reason I initially hesitated purchasing this unit. The unit is lightweight, easy to pick up and carry. The on-off switch is large and easily accessible. The noise level is better than the 15 year old vac its replaced. The stretchable hose isn't cumbersome, I don't feel like I'm fighting the hose when reaching around different areas inside the car, I don't see a great need to upgrade to the orange Pro hose *yet*. I chose this model specifically because of the tool-box design and on-board storage - everything stores away inside the unit, cord, hose, accessories. All compartments are easy to open, the lids of the 2 storage bays open and remain open without fuss. I also purchased an additional accessory nozzle (Model #VT1739) that fits in the storage bay along side the included accessories. Everything I need is stored inside the "vac-box", it's great, a neat and clean design. Love that it tucks away on a shelf in my garage. I definitely recommend this unit, unless you have a routine need to suck up a lot of water.
