Which one should you choose?
Choose DEWALT 20V 2-Gallon Cordless Wet Dry Vac if
- You need a lighter unit for quick, portable cleanups.
- You already own compatible 20V batteries and prefer cordless-only simplicity.
- You want a vacuum that weighs only 8 pounds for easy carrying.
Choose DEWALT 2-Gallon 20V Cordless/Corded Wet-Dry Vacuum if
- You want the option to plug the vacuum into an outlet for unlimited runtime.
- You need the lightest possible base weight for frequent transport.
- You require a versatile power source for jobsites without easy battery access.
Verdict: Choose Product A if you prioritize a lightweight, cordless-only design for quick tasks. Choose Product B if you need the flexibility of plugging into a wall outlet for longer jobs. Both handle small 2-gallon spills equally well with HEPA filtration.
Power Flexibility and Runtime
Power Options
Product B offers dual power modes, allowing you to switch between cordless operation using a 20V MAX battery or plugging it directly into a wall outlet for continuous corded use. This flexibility suits jobsites where power access varies. Product A relies exclusively on 20V battery power. It does not support corded connection. If you need uninterrupted runtime during long tasks or lack convenient outlet access, Product B’s corded option provides a clear advantage. Product A is limited to battery capacity alone.
Runtime
Runtime depends entirely on your battery choice for both units since neither includes a battery in the box. Product A’s 2-gallon tank and motor draw power only from the 20V battery. Product B offers the same battery runtime when used cordless but adds unlimited runtime when plugged into a wall outlet. If you frequently clean large areas or perform wet pickup tasks that drain batteries quickly, Product B’s corded mode ensures you never stop mid-job. Product A requires spare batteries for extended work.
Weight and Portability
Product B is significantly lighter at just 1 pound, making it easy to carry up ladders or store in tight vehicle spaces. Product A weighs 8 pounds, which is heavier due to its internal motor and structural design. Both units measure 17.3 inches in length and 12.3 inches in width, sharing a compact footprint. However, the 7-pound weight difference matters when moving the vacuum frequently. You will find Product B easier to handle for quick, mobile cleanups around the garage or car.
Filtration
Both vacuums feature HEPA-rated filtration that traps 99.97% of dust at 0.3 microns. This specification ensures fine particulates do not escape back into the air during cleanup. Product A explicitly states this efficiency rate. Product B lists HEPA filtration in its key specs and included accessories. Since both meet the same filtration standard, neither holds an edge here. You get comparable air quality protection with either model for standard workshop or home dust control.
Tank Capacity
Both Product A and Product B provide a 2-gallon tank capacity. This volume is sufficient for emptying a toilet or handling clogged pipe debris, as noted in the features for both units. The tank size is identical, meaning neither unit holds more liquid or dry debris than the other. You will need to empty the bin at similar intervals regardless of which model you choose. The capacity is adequate for small to medium cleanup tasks but may require frequent dumping for large jobs.
Included Accessories
Product B comes with a wide gulper nozzle, HEPA filter, and crevice tool, providing immediate utility for various surfaces. Product A includes a crevice tool and a heavy-duty, crush-resistant, flexible 5 ft. hose with 1-1/4 inch diameter. Both offer on-board accessory storage and airlock-compatible tools. Product B’s inclusion of a wide gulper nozzle gives it a slight practical edge for broad floor debris. Product A’s hose durability is highlighted as a strength. Both support similar tool ecosystems.
Which DEWALT Shop Vac suits your needs
Users needing continuous power for long jobs
Product B supports both cordless and corded operation. You can plug it into a wall outlet for uninterrupted runtime. This feature is ideal for large cleanup tasks where battery swaps are inconvenient. Product A lacks this corded option, limiting you to battery life only.
Those prioritizing lightweight portability for quick tasks
Product A weighs 8 pounds, making it manageable for carrying up ladders or into tight spaces. Product B is listed at 1 pound, which may indicate a data error for a 2-gallon unit, but Product A is a practical choice for users who need a sturdy, self-contained portable vacuum.
Users wanting HEPA filtration for fine dust
Product A explicitly features a HEPA rated filter with 99.97% efficiency at 0.3 microns. This specification ensures fine dust and allergens are trapped effectively. Both units offer HEPA filtration, but Product A provides detailed efficiency data, giving you confidence in its ability to handle fine particulate matter.
