Gas vs Cordless Pressure Washer Specs
Power Source
The Westinghouse WPX3200 runs on a 212cc 4-stroke gas engine. You must handle fuel, oil, and maintenance. It requires a manual recoil start. The DEWALT DCPW550BR is a cordless tool. It uses 20V MAX batteries. You need to buy batteries and a charger separately. The listing is for the tool only. Cordless operation eliminates fuel storage and fumes. Gas power offers continuous runtime without battery swaps. Cordless power offers instant start and zero emissions. You choose based on your preference for fuel management or battery convenience.
Maximum Pressure
Pressure determines how well you strip dirt and grime. The Westinghouse unit delivers 3200 PSI. This high pressure handles tough stains on concrete, driveways, and decks. The DEWALT model provides 550 PSI. This level is gentle and suitable for light dusting or vehicle washing. It is not designed for heavy-duty cleaning tasks. The difference is significant. You need 3200 PSI for deep cleaning. You need 550 PSI for delicate surfaces. The gas model wins for raw cleaning force.
Flow Rate
Flow rate measures water volume per minute. The Westinghouse pump moves 2.5 gallons per minute. This volume helps rinse away loosened debris quickly. The DEWALT cleaner outputs 1 gallon per minute. This lower flow is sufficient for light rinsing. Higher flow rates reduce cleaning time for large areas. You will rinse faster with the Westinghouse unit. The DEWALT flow is adequate for small, light jobs. The gas model provides superior water volume for efficiency.
Hose Length
Reach affects your ability to clean large areas without moving the machine. The Westinghouse includes a 25-foot abrasion-resistant hose. This length allows you to clean driveways or siding from a central point. The DEWATT model has no hose length listed. It connects to a garden hose via a quick connect adaptor. This means you rely on your existing hose length. The DEWALT is portable but depends on your water source proximity. The Westinghouse offers built-in reach for independent operation.
Nozzle Count
Nozzles control spray patterns for different surfaces. The Westinghouse comes with five quick-connect nozzles. These include 0, 15, 25, and 40-degree tips plus a soap nozzle. This variety allows precise cleaning for fences, cars, and decks. The DEWALT nozzle count is not listed in the data. It likely has a fixed spray pattern. The Westinghouse offers flexibility for various cleaning tasks. You can switch patterns instantly. The gas model provides better versatility for different jobs.
Weight and Size
Portability matters for storage and transport. The Westinghouse weighs 63 pounds. It measures 39 inches in height. It has 12-inch never-flat wheels for movement. The DEWALT measures 11 inches in height, 5 inches in width, and 25 inches in length. Its weight is not listed. The DEWALT is significantly smaller and lighter. It is easy to carry and store. The Westinghouse is a stationary unit that requires wheels. You prefer the DEWALT for easy handling.

Frequently asked questions
Can I use a cordless pressure washer on a concrete driveway?
You can, but results vary by model. The DEWALT DCPW550BR is designed for light cleaning tasks. It lacks the high pressure needed for deep concrete stains. For stubborn grime on driveways, a gas unit like the Westinghouse WPX3200 is more effective. Its 3200 PSI output handles tough jobs better than low-pressure cordless tools.
Do I need a water hose for a cordless pressure washer?
Most cordless models still require a water source. The DEWALT DCPW550BR cleans without a hose connection for specific light tasks. However, it relies on battery power rather than water pressure. For general cleaning, you likely need a water supply. Gas models like the Westinghouse WPX3200 connect directly to a hose for continuous flow.
How heavy is a typical gas pressure washer compared to a cordless one?
Gas units are significantly heavier due to their engines. The Westinghouse WPX3200 weighs 63 pounds. It measures 39 inches tall and includes a fuel tank. Cordless options are lighter and more portable. The DEWALT DCPW550BR weighs less and fits in tighter spaces. You move the gas unit less frequently because of its weight.
What PSI is enough for cleaning patio furniture?
Lower pressure is often safer for delicate items. The DEWALT DCPW550BR offers a compact, low-pressure option. It is suitable for cleaning patio furniture without damaging surfaces. High-pressure gas washers like the Westinghouse WPX3200 at 3200 PSI may be too intense. Use the lower setting or a wider nozzle for delicate materials.
Can I attach a soap tank to a cordless pressure washer?
Check the specific model features. The Westinghouse WPX3200 includes a built-in soap tank for applying detergent. The DEWALT DCPW550BR does not list this feature in its specifications. Cordless tools often focus on water-only cleaning for quick tasks. If you need to apply soap, the gas model provides a dedicated tank for easier application.
Is a gas pressure washer better for washing fences?
Gas models generally provide the power needed for fences. The Westinghouse WPX3200 is intended for fences and homes. Its 2.5 GPM flow rate rinses debris effectively. The DEWALT DCPW550BR is better for small, light tasks. It may not remove deep dirt from fence slats. Use the gas unit for thorough cleaning of vertical surfaces.
Do I need special batteries for a cordless pressure washer?
You need compatible batteries for the specific brand. The DEWALT DCPW550BR uses 20V MAX batteries. If you already own DeWalt batteries, you can use them immediately. This saves you from buying a separate power source. Gas washers do not use batteries but require fuel and oil. Choose cordless if you want to leverage existing tool inventory.
