Handheld vs Wet Dry Key Specs
Power source
The DEWALT 20V Cordless Hand Vacuum runs on a 20V battery, offering true cordless freedom. You can use it anywhere without hunting for outlets. The DEWALT 4-Gallon Poly Wet/Dry Vacuum is a corded unit, requiring a power source for operation. This limits its mobility but ensures consistent power delivery. For quick cleanups in tight spots or areas without nearby power, the cordless design is more convenient. For heavy-duty jobs where you need uninterrupted power, the corded option is reliable.
Capacity
Capacity defines how much debris each vacuum can hold before you must empty it. The DEWALT 4-Gallon Poly Wet/Dry Vacuum features a 4-gallon tank, allowing you to collect large volumes of dust, water, or debris in one go. This is ideal for garage or workshop cleanup. The DEWALT 20V Cordless Hand Vacuum does not list a specific capacity in its specs, but its handheld design implies a much smaller canister. You will likely need to empty it more frequently during larger tasks. The wet/dry model wins for volume.
Weight
Weight affects how comfortable the tool is to hold and maneuver. The DEWALT 20V Cordless Hand Vacuum weighs 6.83 pounds, making it relatively light for a power tool. You can hold it in one hand for extended periods without significant fatigue. The DEWALT 4-Gallon Poly Wet/Dry Vacuum weighs 13.2 pounds. While lighter than many shop vacs, it is nearly twice as heavy as the handheld unit. You will likely keep the wet/dry vacuum on the floor rather than carrying it around. The handheld option is easier to lift and carry.
Filtration
Filtration quality matters for fine dust and indoor air quality. The DEWALT 20V Cordless Hand Vacuum includes a HEPA filter, which captures fine particles like concrete dust and drywall residue. This ensures cleaner air is exhausted back into the room. The DEWALT 4-Gallon Poly Wet/Dry Vacuum does not list a specific filtration type in its provided specifications. It is designed for wet/dry use, but you cannot confirm if it traps fine dust as effectively as the HEPA system. For fine dust control, the handheld unit has a clear advantage.
Versatility
Versatility determines what types of messes each vacuum can handle. The DEWALT 4-Gallon Poly Wet/Dry Vacuum is explicitly labeled as a wet/dry unit. This means you can vacuum up spills, water, and liquids in addition to dry debris. The DEWALT 20V Cordless Hand Vacuum is described as a dry hand vacuum. It is not designed for liquids. If you need to clean up a spill in the garage or a wet mess in the workshop, the wet/dry model is the only suitable choice. The handheld unit is strictly for dry debris.
Which DEWALT Vacuum Fits Your Needs
Users needing quick cleanup of fine dust

People cleaning large areas or spills

Those prioritizing runtime for extended use
