The DeWALT DCV517B 20V MAX 1/2 Gallon Wet/Dry Portable Vac is a cordless handheld vacuum built for quick jobsite cleanup, service work, and punch-list debris pickup. This is a handheld wet/dry vacuum designed for portable cleanup of dust, debris, and small wet messes. Model Number: DCV517B. If you already run DEWALT 20V MAX batteries, this gives you a compact way to clean up without dragging out a full-size shop vacuum.

What makes this vacuum useful is that it is built for the kind of messes that slow you down between tasks. The 1/2 gallon tank is small enough to keep the tool light and easy to carry, but still big enough for quick pickup of sawdust, drywall dust, general debris, and small spills. The dual cleanup setup lets you work with either the front utility nozzle or the extendable rubber hose, so you can go from flat-surface cleanup to tighter spaces without switching to a bigger machine.

The filtration side is the real selling point here. DEWALT equips the DCV517B with a Gore HEPA wet/dry filter that traps 99.97% of dust at 0.3 microns. That matters if you are cleaning up fine dust from trimming, drilling, light concrete dust, or interior finish work where you do not want debris blowing back around the room. The filter is also washable, so routine maintenance is simple. Tap it clean or rinse it with water when the job calls for it.

From a design standpoint, this portable vacuum is clearly aimed at real-world use instead of shelf appeal. The heavy-duty rubber hose is built to flex without feeling flimsy, and the large on/off switch is easy to hit with one hand when you are moving fast. The tank latch is heavy-duty as well, which matters because a weak latch is one of the first things to become annoying on compact vacuums that get used hard. At about 4.5 lbs, it stays manageable for overhead cleanup, stair work, and truck-to-job carry.

Battery platform compatibility is straightforward. The DCV517B runs on DEWALT 20V MAX battery packs, making it a logical add-on for users already invested in that cordless system. It is sold as a tool only, so batteries and charger are not included. That is not a drawback if you already own the platform, but it is worth knowing before you order.

The hose diameter is 1-1/4 in., and hose length is listed at 2.5 ft. to 3 ft., which tells you the goal here is close-range cleanup rather than replacing a full shop vac. This is the tool you grab for cabinet installs, finish carpentry touch-ups, service van cleanup, or clearing out debris after drilling and fastening work. It is not pretending to be a large-capacity cleanup machine, and that is exactly why it works well.

If you are a remodeler, electrician, HVAC tech, punch-out carpenter, or serious DIYer who wants fast cordless cleanup, this vacuum makes sense. If your work creates constant small messes and you are tired of hauling a full-size vacuum for every little task, the DeWALT DCV517B 20V MAX 1/2 Gallon Wet/Dry Portable Vac is the kind of tool that earns its spot in the truck pretty quickly.
