Choosing between an electric vs gas pressure washer depends on your cleaning needs. Both units deliver high-pressure water for outdoor tasks like washing cars, patios, and driveways. The main difference lies in their power source. One uses a plug-in motor for quiet, low-maintenance operation. The other relies on a gasoline engine for higher output. You must decide which specs match your project scope.

Electric vs Gas Pressure Washer Specs
Power source
The Sun Joe SPX1000 relies on a 13-amp electric motor, requiring a standard GFCI outlet via its 35-foot power cord. You plug it in and start immediately. The Westinghouse WPX3200 uses a 212cc gas engine with recoil start. It runs on gasoline stored in a 0.9-gallon tank. This allows you to move away from outlets. Electric models offer quiet operation and zero emissions at the point of use. Gas models provide unrestricted mobility for large properties or remote jobs where power is not available. Choose electric for convenience and gas for range.
Pressure
Cleaning power often starts with maximum pressure. The Sun Joe delivers 1600 PSI. This is sufficient for light to medium tasks like washing cars, patio furniture, and siding. It handles general grime well. The Westinghouse produces 3200 PSI. This nearly doubles the force of the electric unit. Higher pressure cuts through tough stains, caked-on mud, and thick paint more effectively. It is better for heavy-duty jobs like cleaning garage floors or stripping decks. If you have heavy dirt buildup, the gas model has a clear advantage. For routine maintenance, the electric unit is adequate.
Flow rate
Flow rate determines how much water hits the surface per minute. The Sun Joe moves 1.2 GPM. The Westinghouse moves 2.5 GPM. This is more than double the water volume. Higher flow rate rinses away loosened dirt faster. It reduces the time needed to clean large areas like driveways or siding. The Sun Joe’s lower flow rate means you may need to spend more time scrubbing or rinsing. The Westinghouse washes away debris more efficiently. If you value speed and thorough rinsing, the gas model’s higher flow rate is a significant practical benefit.
Hose length
Reach matters when cleaning large spaces. The Sun Joe includes a 20-foot high-pressure hose. The Westinghouse includes a 25-foot abrasion-resistant super-flex hose. The gas model gives you an extra five feet of reach. This allows you to clean further from your power source or vehicle without moving the unit. The Sun Joe’s shorter hose may require you to reposition the washer more often. Both hoses are sufficient for most residential tasks. However, the additional length on the Westinghouse offers more flexibility for larger yards or long driveways.
Nozzle count
Versatility comes from the number of spray options. The Sun Joe features an adjustable spray wand with a twist nozzle. You switch between a zero-degree jet and a 45-degree fan. This is simple and effective. The Westinghouse comes with five quick-connect nozzles: 0, 15, 25, 40 degrees, and soap. Having dedicated nozzles allows you to switch patterns quickly without twisting a dial. The five options cover a wider range of surface sensitivities and cleaning needs. You can optimize the spray angle for specific tasks. The gas model offers more specialized control.
Build and weight
Portability and durability differ significantly. The Sun Joe weighs 11.7 pounds and measures 19 inches high. It is lightweight and compact, making it easy to store in a garage or carry upstairs. The Westinghouse weighs 63 pounds and stands 39 inches tall. It is heavy and requires 12-inch high-profile wheels for movement. The gas model has a steel frame for durability. The electric unit is lighter plastic. If you need to lift or store the washer frequently, the Sun Joe is easier to handle. If you want a stationary, rugged machine, the Westinghouse is built for it.
Which Pressure Washer Suits Your Needs
Apartment dwellers with limited storage
The Sun Joe SPX1000 weighs just 11.7 pounds and measures 12 by 9.8 by 19 inches. Its compact design fits easily in small closets or under sinks. You avoid the bulk of gas models. The 35-foot GFCI power cord reaches outlets without extension cords. This lightweight electric unit is ideal for tight spaces and light cleaning tasks around the home.
Users needing high pressure for tough jobs
The Westinghouse WPX3200 delivers 3200 PSI and 2.5 GPM, offering significantly more power than electric options. Its 212cc gas engine handles heavy grime on driveways and decks. The axial cam pump provides durable performance for demanding projects. You get robust cleaning capability for stubborn dirt that lighter units cannot remove effectively from large surfaces.
Buyers wanting built-in soap and mobility
This gas model features a 0.9-gallon onboard soap tank for applying detergent directly. It includes five quick-connect nozzles for varied spray patterns. The steel frame and 12-inch never-flat wheels make it easy to move across uneven terrain. You gain flexibility in application and transport without needing to mix soap separately.

Frequently asked questions
Are electric pressure washers powerful enough for driveways?
Most electric models lack the force needed for heavy concrete cleaning. The Sun Joe SPX1000 delivers 1.2 GPM and is best for small surfaces like cars. For driveways, you typically need higher PSI and flow rates found in gas units. Electric machines excel at light tasks where portability matters more than raw power.
How much does a gas pressure washer weigh?
Gas models are significantly heavier due to their engines and fuel tanks. The Westinghouse WPX3200 weighs 63 pounds and measures 21 by 19.5 by 39 inches. This bulk provides stability and power but requires more effort to move. Electric units like the Sun Joe SPX1000 weigh only 11.7 pounds for easy storage.
Do gas pressure washers have soap tanks?
Many gas models include dedicated soap tanks for applying detergent. The Westinghouse WPX3200 features a built-in soap tank and comes with five nozzles for different cleaning tasks. This setup allows you to switch between cleaning agents and rinsing quickly. Electric units often rely on external bottles or siphon tubes instead.
What is the flow rate difference between electric and gas?
Gas pressure washers generally offer higher flow rates for faster rinsing. The Westinghouse WPX3200 provides 2.5 GPM, which cleans large areas quickly. Electric models like the Sun Joe SPX1000 offer 1.2 GPM. This lower flow rate is sufficient for small jobs but may take longer on larger surfaces like patios or fences.
Can I use an electric pressure washer indoors?
Electric pressure washers are safer for indoor use because they produce no exhaust fumes. The Sun Joe SPX1000 is lightweight and compact, making it easy to store in small spaces. Gas units emit carbon monoxide and should never be used in enclosed areas. Always ensure proper ventilation when operating any pressure washer.
How many nozzles come with a gas pressure washer?
Gas pressure washers often include multiple nozzles for various cleaning tasks. The Westinghouse WPX3200 comes with five nozzles to adjust spray patterns. This versatility helps you clean cars, patios, and homes effectively. Electric models may include fewer nozzles or require separate purchases for specific cleaning needs.
