How to tell DEWALT Shop Vacuum Models apart: What DXV05S-QT Means
Published June 9, 2026If you’ve spent any time shopping for a DEWALT shop vacuum, you’ve probably come across model numbers like DXV05S-QT, DXV06P, or DXV12P-QT.
At first glance, these model numbers seem like a random mix of letters and numbers. In reality, DEWALT uses a fairly logical naming system that tells you the vacuum’s size, tank material, and key features before you even read the specifications.
If you’ve already read our guide to Understanding DEWALT Model Numbers, this article follows the same approach—breaking down DEWALT’s shop vacuum lineup so you can quickly identify the right model for your garage, workshop, or jobsite.
Breaking Down a DEWALT Shop Vacuum Model Number
Let’s use the DXV05S-QT as an example.
DXV05S-QT
Each section of the model number has a meaning.
DXV = DEWALT Wet/Dry Vacuum
The first three letters identify the product family.
- DXV = DEWALT wet/dry vacuum
- Most corded DEWALT shop vacuums use the DXV designation
- These are the traditional canister-style wet/dry vacuums designed for workshops, garages, and jobsites.
If you see a model beginning with DCV, you’re looking at one of DEWALT’s cordless jobsite vacuums instead of a traditional shop vac.

Stealthsonic models incorporate a redesigned motor housing and airflow system that helps dampen sound without sacrificing suction power.

The numbers in the model name generally correspond to the vacuum’s tank size in gallons.
| Model Prefix | Tank Capacity | |
|---|---|---|
 | DXV04 | 4 Gallons |
 | DXV06 | 6 Gallons |
 | DXV09 | 9 Gallons |
 | DXV16 | 16 Gallons |
In general:
- 4–6 gallon models prioritize portability.
- 8–12 gallon models balance capacity and maneuverability.
- 14–20 gallon models are designed for workshops, garages, and larger cleanup jobs.
S vs. P: Understanding Tank Materials
S = Stainless Steel | Stainless steel models offer a premium appearance and are often easier to rinse clean after wet pickup. Examples: DXV05S, DXV08S, DXV10S, DXV10SA |
P = Poly Tank | Poly tanks are lighter, resistant to dents, and commonly found on larger-capacity models. Examples: DXV06P, DXV09P, DXV12P, DXV14P, DXV16P |
T = Compact Portable Design | These models use a compact form factor designed for portability and quick cleanup jobs. Example: DXV04T |
G = Garage Models | The “G” designation is generally used for garage-oriented or wall-mounted vacuums designed to remain in a fixed location. Example: DXV06G |
A and B Suffixes | These are typically accessory-package variations rather than completely different vacuums. Example: DXV10SA, DXV10SB |
What Does QT Mean on a DEWALT Shop Vac?
One of the most common questions shoppers ask is: “What does QT mean on a DEWALT shop vac?”
The answer is straightforward:
QT = Quiet Technology (Stealthsonic)
DEWALT uses the Stealthsonic branding for its quieter shop vacuum lineup.
Examples include:
- DXV05S-QT
- DXV06P-QT
- DXV10S-QT
- DXV12P-QT
- DXV16P-QT
DEWALT Stealthsonic models are built for users who want the cleaning power of a full-size shop vacuum without the ear-splitting noise. DEWALT redesigned these vacuums to better manage motor and airflow noise, resulting in a quieter operating experience while maintaining strong suction for sawdust, debris, and liquid cleanup. While traditional shop vacs can quickly dominate a garage or workshop with noise, Stealthsonic models are designed to be less disruptive during use. DEWALT claims some models operate below 65 dBA and can be up to 50% quieter than comparable standard shop vacuums, making them a compelling option for homeowners and DIYers who regularly work in attached garages or shared spaces.
For many homeowners, the Stealthsonic models are easier to use indoors, in attached garages, or around family members because they produce less of the high-pitched shop-vac noise that many people dislike.
If you’re deciding between a standard model and a QT model, the QT version is typically the better choice if quiet operation is important to you.
What Is the Difference Between QT and QTA?
You may also encounter models such as:
- DXV12P-QT
- DXV12P-QTA
The vacuum itself is generally the same. The difference is usually the included accessory package.
Based on retailer documentation and owner discussions, QTA models often include DEWALT’s upgraded yellow contractor hose and additional accessories or dust bags, while standard QT models include the standard hose package.
For most buyers, this is not a performance difference—it’s an accessories difference.

Final Thoughts

For example:
- DXV05S-QT = 5-gallon stainless steel quiet model
- DXV12P = 12-gallon poly tank standard model
- DXV16P-QT = 16-gallon poly tank Stealthsonic model
Instead of comparing specifications page by page, you can often identify the most important differences just by looking at the model number.
And if you see QT at the end, you’ll know immediately that you’re looking at one of DEWALT’s quieter Stealthsonic shop vacuums.
