Capacity, Size, and Features Compared
Tank capacity
The DEWALT 6-Gallon 20V Cordless Wet/Dry Vacuum offers a significantly larger 6-gallon tank compared to the 2-gallon capacity of the DEWALT 2-Gallon Cordless Wet/Dry Vacuum. This larger volume allows you to handle more debris, such as sawdust or larger spills, before needing to empty the canister. The 2-gallon model is compact, which may suit smaller tasks like clearing a toilet or clogged pipe, but requires more frequent emptying during larger jobs. If you are doing extensive cleanup in a garage or workshop, the 6-gallon unit reduces interruptions. For quick, small messes, the smaller tank is sufficient.
Physical dimensions
Size differences are notable between these two cordless vacuums. The DEWALT 6-Gallon 20V Cordless Wet/Dry Vacuum measures 17.2 inches in width, 23.9 inches in height, and 18.5 inches in length. In contrast, the DEWALT 2-Gallon Cordless Wet/Dry Vacuum is much more compact, measuring 12.3 inches in width, 13.1 inches in height, and 17.3 inches in length. The smaller unit fits easily into tight spaces or small car trunks. The larger unit takes up more storage space but offers greater internal volume. Consider your storage constraints and the size of the areas you need to clean when choosing between the two form factors.
Weight
Portability is influenced heavily by weight. The DEWALT 2-Gallon Cordless Wet/Dry Vacuum weighs only 10 pounds, making it very easy to carry up ladders or into vehicles. The DEWALT 6-Gallon 20V Cordless Wet/Dry Vacuum is substantially heavier at 27.6 pounds. While it includes a portable handle, the increased mass may make it less convenient for overhead cleaning or frequent repositioning. If you need to move the vacuum often or store it in a tight space, the lighter 2-gallon model is more manageable. For stationary use in a workshop, the heavier unit provides more capacity.
Filtration
Filtration specs differ in the provided data. The DEWALT 2-Gallon Cordless Wet/Dry Vacuum features a HEPA-rated wet-dry filter that is washable and reusable, trapping 99.97 percent of particles at 0.3 microns. This is ideal for fine dust and allergens. The DEWALT 6-Gallon 20V Cordless Wet/Dry Vacuum includes a cartridge filter, a foam filter, and a disposable dust bag, but specific HEPA ratings or micron efficiency are not listed in the available specifications. If capturing fine dust is your priority, the HEPA rating on the 2-gallon model is a clear advantage. For general debris, the bag and filter combo on the larger unit is effective.
Additional features
The DEWALT 6-Gallon 20V Cordless Wet/Dry Vacuum includes a built-in blower function, allowing you to switch from vacuuming to blowing leaves or debris from driveways and patios. This adds versatility for outdoor or garage use. The DEWALT 2-Gallon Cordless Wet/Dry Vacuum does not list a blower feature in its specifications. Both units are cordless and use the 20V MAX battery system. If you need a tool that can also blow debris, the 6-gallon model offers this extra capability. For pure vacuuming tasks, both units perform their core function without this additional mode.
Which DEWALT Wet Dry Vacuum Fits You
Users needing high-efficiency fine dust filtration
The 2-gallon model includes a HEPA-rated filter that traps 99.97 percent of particles at 0.3 microns. This specification makes it ideal for capturing fine dust and allergens. You can wash and reuse this filter easily. If air quality and fine particle capture are your priority, this smaller unit delivers the necessary filtration performance for your workspace.
Those handling large debris or liquid spills
With a 6-gallon tank, this vacuum holds significantly more debris than the 2-gallon alternative. You will empty it less often when cleaning large areas like garages or workshops. The larger capacity handles sawdust and liquid spills with ease. It reduces the frequency of interruptions, allowing you to complete bigger jobs without stopping to dump the tank.
People needing outdoor versatility and blowing
This model features a built-in blower function, adding versatility beyond standard vacuuming. You can switch modes to clear leaves, dust, or debris from driveways and patios. This dual capability is not mentioned for the 2-gallon unit. If you need to move light debris outdoors as well as vacuum indoors, this larger tool offers that extra utility.
Users prioritizing lightweight portability and storage
Weighing only 10 pounds, this vacuum is much lighter than the 27.6-pound 6-gallon model. Its compact dimensions of 12.3 by 13.1 by 17.3 inches make it easier to store in tight spaces. If you frequently move the vacuum between cars or small work areas, the reduced weight and smaller footprint will make handling it significantly less cumbersome.

Frequently asked questions
Can the DEWALT 2-Gallon vacuum handle large spills?
No, this unit is designed for small spills and tight spaces. Its 2-gallon tank capacity is limited, making it unsuitable for large cleanup tasks. You should use the 6-Gallon model if you need to manage significant liquid volumes or heavy debris loads on a jobsite.
Is the 6-Gallon model heavier than the 2-Gallon version?
Yes, the 6-Gallon vacuum weighs 27.6 pounds, which is significantly heavier than the 10-pound 2-Gallon unit. The larger tank and motor assembly add substantial mass. You will notice a difference in portability, so consider how often you need to carry it up stairs or into tight areas.
Do both vacuums run on the same battery platform?
Yes, both the DEWALT 2-Gallon and 6-Gallon models operate on the 20V MAX battery platform. You can use your existing 20V batteries with either unit. This compatibility allows you to switch tools without buying new power sources, provided you already own DEWALT 20V MAX batteries.
Does the 6-Gallon vacuum include a blower function?
Yes, the DEWALT 6-Gallon 20V Cordless Wet/Dry Vacuum features a blower function. This adds versatility for clearing debris from work areas or blowing light dust. The 2-Gallon model does not list this feature, so you must check its specific capabilities if you need dual functionality.
Which vacuum is better for small workshop messes?
The DEWALT 2-Gallon Cordless Wet/Dry Vacuum is better for small spills and tight spaces. Its compact dimensions of 12.3 inches wide and 17.3 inches long allow it to fit in smaller areas. The lighter weight also makes it easier to maneuver in confined workshops or vehicle interiors.

The 6-Gallon model measures 17.2 inches in width, 23.9 inches in height, and 18.5 inches in length. These larger dimensions accommodate its increased 6-gallon capacity. You need more floor space to store or operate this unit compared to the more compact 2-Gallon alternative.
Can I use the 2-Gallon vacuum for wet pickup?
Yes, the DEWALT 2-Gallon Cordless Wet/Dry Vacuum is rated for both wet and dry use. You can safely pick up liquids as well as dry debris. However, its small 2-gallon tank limits the volume of liquid you can collect at one time before needing to empty it.
