Setup
Follow these steps to assemble your DEWALT Wet/Dry Vacuum and prepare it for use.
1. Attach Casters (Wheels)
The vacuum comes with heavy-duty swiveling casters for easy mobility. Securely attach them to the base of the vacuum according to the instructions provided in the included manual.

2. Install Filters
Depending on whether you are performing wet or dry vacuuming, you will need to install the appropriate filter. For dry vacuuming, use the washable cartridge filter. For wet vacuuming, a foam filter (sold separately or included in some kits) is typically used, or no filter if specified for certain wet applications. Ensure the filter is correctly seated to prevent damage to the motor.
3. Connect Hose and Accessories
Attach the 2-1/2 inch x 7 ft hose to the quick-connect locking vacuum port. Select the desired accessory (e.g., extension wands, floor nozzle, crevice nozzle, round brush, utility nozzle) and firmly attach it to the end of the hose.

Operating Instructions
The DEWALT DXV12P-QTA is designed for both wet and dry cleaning tasks, featuring STEALTHSONIC technology for quieter operation.
1. Dry Vacuuming
Ensure the cartridge filter is installed for dry debris collection. Connect the desired dry-use attachment (e.g., floor nozzle for large areas, crevice tool for tight spaces). Plug the vacuum into a suitable power outlet and turn on the large on/off switch. Begin vacuuming, moving the attachment over the area to be cleaned.
2. Wet Vacuuming
For wet pickup, remove the cartridge filter and install a foam filter (if available and recommended for your model) or ensure no dry filter is present. Connect a wet-use attachment (e.g., utility nozzle). Plug in the vacuum and turn it on. Guide the attachment over liquid spills to collect them. Do not overfill the tank; the vacuum has an automatic shut-off when full.
3. Using Attachments
The vacuum comes with a variety of attachments for different cleaning needs:
- Floor Nozzle: Ideal for general dry and wet pickup on large floor areas.
- Crevice Nozzle: Perfect for reaching into narrow spaces, corners, and between car seats.
- Round Brush: Suitable for dusting and cleaning irregular surfaces.
- Utility Nozzle: Versatile for various cleaning tasks, including wet pickup.
- Extension Wands: Extend your reach for floors, ceilings, or deep car interiors.

Maintenance
Regular maintenance ensures optimal performance and extends the life of your DEWALT Wet/Dry Vacuum.
1. Emptying the Tank
For wet pickup, the 12-gallon tank can be easily emptied using the built-in drain plug located at the bottom of the tank. For dry debris, unlatch the motor head and carefully lift it off, then dispose of the contents from the disposable dust bag or directly from the tank if not using a bag.

2. Cleaning and Replacing Filters
The washable cartridge filter can be cleaned by tapping off loose debris or rinsing with water. Allow it to air dry completely before reinstallation. Replace filters when they show signs of wear or reduced performance. For wet applications, ensure the foam filter is clean and properly installed, or removed if not required.
3. Hose and Accessory Storage
The top handle and side wraps provide convenient organization for the hose and power cord. Store accessories in the included accessory bag to keep them readily available and prevent loss.
Troubleshooting
If you encounter issues with your DEWALT Wet/Dry Vacuum, refer to the following common troubleshooting tips:
- Loss of Suction: Check for blockages in the hose or attachments. Ensure the tank is not full (especially during wet pickup). Verify that the filter is clean and correctly installed.
- Motor Not Starting: Confirm the power cord is securely plugged into a working outlet. Check the on/off switch for proper engagement. Ensure the motor head is securely latched onto the tank.
- Unusual Noise: Inspect for any foreign objects caught in the impeller or hose. Ensure all connections are tight.
