Cordless Unit vs Surface Cleaner
Power Source
The DEWALT 550 PSI Cordless Power Cleaner (DCPW550B) operates as a standalone cordless tool. It delivers cleaning power without being tethered to an electrical outlet. You must provide your own battery and charger, as they are not included. This design prioritizes portability and freedom of movement around your property. In contrast, the DEWALT 18-Inch Cold Water Surface Cleaner (DXPA37SC) is an attachment. It does not have its own motor or power source. You must connect it to an existing cold water pressure washer to function. It relies entirely on the power output of your main machine.
Pressure Output
Pressure capability differs significantly between these two items. The cordless pressure washer generates a maximum of 550 PSI. This level is sufficient for light-duty tasks like rinsing patio furniture, cleaning cars, or washing down decks. It provides ten times the power of a standard garden hose. The 18-inch surface cleaner has no independent pressure rating. It is rated to work with pressure washers that output up to 3700 PSI. This means the surface cleaner can handle much higher pressures when attached to a powerful machine. It is built to withstand intense water force for stubborn stains on concrete.
Water Flow Rate
Flow rate determines how much water is delivered during cleaning. The DEWALT cordless unit has a specified flow rate of 1.0 GPM. This steady stream helps rinse away dirt while conserving water compared to larger gas models. The surface cleaner does not list a specific GPM in the provided data. Its effectiveness depends on the flow rate of the pressure washer it connects to. If you attach it to a high-flow machine, it will move more water. For the cordless unit, the 1.0 GPM is a fixed specification that defines its cleaning capacity.
Intended Use
These tools serve different primary purposes. The cordless pressure washer is a complete cleaning system. You can use its variable speed control and quick-connect nozzles for various tasks. It draws water from any fresh water source, including buckets or hoses. It is ideal for general cleaning around the home. The 18-inch surface cleaner is specialized for flat surfaces. It is designed to clean driveways, sidewalks, and large concrete areas evenly. It prevents the streaking often caused by handheld wands. It is not a standalone cleaner but a high-efficiency attachment for large hardscapes.
Build and Size
Physical dimensions and weight affect how you handle each tool. The cordless pressure washer measures 23.7 inches in length, 10.9 inches in width, and 6 inches in height. It weighs 9.4 pounds. This size allows for handheld operation and easy storage. The surface cleaner is wider, measuring 18 inches by 18 inches, with a height of 6 inches. It weighs only 5 pounds. Despite being lighter, its large footprint is designed to cover wide swaths of ground quickly. The cordless unit is more compact for maneuvering around obstacles, while the surface cleaner is built for broad, flat coverage.
