Light, portable, versatile, and powerful, DeWalt's new little vac is a great invention. We love that it's powered by a 12- to 18-volt battery, allowing for use when the power's off or you're too far from an outlet, and that you can also plug it in for continuous use. If you're a DeWalt fan, it's likely you already have the 12- to 18-volt batteries and the charger, so the fact that this is sold without those won't affect you. But that's a change we'd like to see DeWalt make. Other than that, it couldn't be better. The five-foot hose is flexible, and the cleaning tools fit on board. The suction's impressive, whether on AC or DC power. Unlike other wet-dry vacs, you don't have to change out the filter innards when switching from wet to dry, and we just love that. Just rinse it off to clean it. Its high-efficiency filter is listed at trapping 99.7 percent of dust, and in our book, less dust in the air is a good thing. When you're wet-vacuuming, just empty the tank through the drain port. It's light as a feather, super-portable, and plenty powerful.--Kris Jensen-Van Heste
