DeWalt 1/2 Gallon Wet/Dry Vacuum, Vacuum only, Battery Not Included. Never used as I bought this new on Amazon, thought I was getting a great deal...then when I got it delivered realized that my battery packs were different then the ones it used (Doh!!). It requires a slide battery pack where I have a clips. So if you have a any DeWalt tools that use a 20V Lithium Ion slide battery packs then this vacuum is for you!! I got it to clean up our cars, seemed ideal for all the food our kids drop.
