Electric vs Cordless Pressure Washer Specs
Power Source
The Sun Joe SPX1000 relies on a 35-foot GFCI power cord, requiring a nearby wall outlet for operation. This setup provides continuous power without worrying about battery levels, making it ideal for fixed locations like driveways or patios. In contrast, the DEWALT DCPW550BR is a tool-only cordless unit powered by 20V MAX batteries. This design offers complete mobility, allowing you to clean areas far from electrical outlets. You must purchase batteries separately for the DEWALT model. The Sun Joe is ready to use immediately upon plugging in, while the DEWALT requires battery investment for basic functionality.
Maximum Pressure
Pressure determines how effectively a washer removes stubborn grime. The Sun Joe electric model delivers 1600 PSI, providing robust cleaning power for light to medium-duty tasks. This pressure level is suitable for car washing, deck maintenance, and removing driveway grime. The DEWALT cordless cleaner offers a significantly lower maximum pressure of 550 PSI. While it claims to deliver ten times the power of a standard garden hose, it is less effective on tough, caked-on dirt. The Sun Joe’s higher PSI makes it more capable for general household cleaning projects that require more force to lift debris from surfaces.
Flow Rate
Flow rate measures the volume of water delivered per minute, affecting rinsing speed. The Sun Joe unit has a flow rate of 1.2 GPM, which helps rinse away loosened dirt efficiently. The DEWALT model provides 1 GPM. Both units draw water from a source, but the Sun Joe connects via a garden hose adapter for a continuous supply. The DEWALT can draw from any fresh water source or connect to a garden hose. The Sun Joe’s slightly higher flow rate means it moves more water, potentially speeding up rinsing compared to the DEWALT, though both are adequate for light cleaning duties.
Hose Length
Reach and mobility are influenced by hose length. The Sun Joe includes a 20-foot high-pressure hose, giving you flexibility to move around larger areas without repositioning the main unit frequently. The DEWALT listing does not specify a hose length, as it is a compact power cleaner often used with direct attachment or short connections. The Sun Joe’s 20-foot hose allows for easier maneuvering around obstacles like furniture or garden beds. If you need to cover a large patio or driveway, the included hose on the Sun Joe provides a practical advantage in terms of operational range and convenience.
Weight and Portability
Portability matters for storage and transport. The Sun Joe weighs 11.7 pounds and measures 19 inches in height, with a compact footprint of 12 by 9.8 inches. It is designed to be lightweight and easy to store in a garage or shed. The DEWALT unit measures 25 inches in length, 11 inches in height, and 5 inches in width. While the DEWALT is tool-only and lighter without a battery, its elongated shape may be less stable for storage. The Sun Joe’s balanced weight and compact dimensions make it easier to carry and store for occasional use around the home.
Which Pressure Washer Fits Your Needs
Homeowners needing strong cleaning power
The Sun Joe SPX1000 delivers 1600 PSI and 1.2 GPM. This higher pressure and flow rate handle stubborn grime on driveways, decks, and siding more effectively than lower-output models. The 20-foot hose and 35-foot power cord keep you connected to continuous power for extended cleaning sessions without interruption.
Users prioritizing portability and ease
The DEWALT DCPW550BR weighs less and lacks a power cord. Its 550 PSI and 1 GPM output suits light duty tasks like rinsing cars or patio furniture. The cordless design allows you to move freely around the yard without managing cables or searching for nearby outlets.
Those with limited storage space
The DEWALT unit measures 25 by 11 by 5 inches. Its compact dimensions make it easier to store in tight spaces like small garages or sheds. The Sun Joe model is larger and heavier, requiring more room for safe and convenient storage when not in use.
Buyers wanting a complete kit
The Sun Joe SPX1000 includes a 33-inch extension wand, hose, and garden hose adapter. It is ready to use right out of the box. The DEWALT is sold as a tool only, meaning you must purchase a separate battery and charger to operate this cordless pressure washer.

Frequently asked questions
Is a cordless pressure washer powerful enough for home use?
Cordless models offer sufficient power for light, portable cleaning tasks. The DEWALT 20V MAX unit is designed for mobility rather than raw force. It allows you to clean areas away from electrical outlets. This makes it ideal for quick jobs where carrying a long cord is inconvenient.
Do I need a long extension cord for electric pressure washers?
Electric units require a nearby wall outlet to operate continuously. The Sun Joe SPX1000 includes a 35-foot GFCI power cord. This length reduces the need for additional extension cords in many standard home settings. You can plug it directly into a standard outlet for steady performance.
Which pressure washer is lighter and easier to store?
The Sun Joe SPX1000 weighs 11.7 pounds and measures 19 inches in height. Its compact size fits easily into small storage spaces. This lightweight design prioritizes portability and ease of storage over heavy-duty power. It is a practical choice for homeowners with limited garage space.
Can I use a cordless pressure washer without water?
No, both electric and cordless pressure washers require a water source to function. The DEWALT cordless model needs water to generate cleaning pressure. You must connect it to a standard garden hose. The unit does not have an internal water tank for self-contained operation.
What is the flow rate of the Sun Joe electric washer?
The Sun Joe SPX1000 has a flow rate of 1.2 GPM. This water volume helps rinse away dirt efficiently after pressure loosens it. Combined with its electric power source, it provides consistent performance for light duty home cleaning tasks like patios or garden furniture.
Is the DEWALT cordless cleaner suitable for heavy grime?
The DEWALT 20V MAX is not designed for heavy grime removal. It is best for light portable cleaning tasks. Its focus is on mobility and convenience rather than high-pressure output. You should use it for dust, light dirt, or quick rinses rather than stubborn stains.
How wide is the DEWALT cordless power cleaner?
The DEWALT DCPW550BR is 5 inches wide. This narrow width makes it easy to maneuver in tight spaces. It pairs with a 25-inch length to create a compact footprint. This design supports its role as a portable tool for areas with limited access.
