Pressure Washer Showdown: Gas vs. Electric Pressure Washers

When your deck, driveway or siding is caked with dirt, a scrub brush and bucket of water won't always clean them. A pressure washer creates a concentrated and highly powerful stream that cleans built-up debris or mold. These machines are available in electric and gas models for both standard and commercial projects. Before deciding which one is best suited for you, it's important to understand the key differences between a gas and an electric pressure washer.

Gas Pressure Washers

Advantages of Gas Pressure Washers

  • Large scale projects - Since a gas power washer typically yields more pressure, it's suitable for large tasks and frequent usage. For instance, a gas model might deliver more PSI to clean gutters, downspouts and wooden surfaces, which normally require plenty of power.
  • Portability - This model doesn't rely on power outlets so it can be transported further from your home or to different jobsites.

Limitations of Gas Pressure Washers

  • High water consumption - Since this model has more power and a higher GPM rating than an electric pressure washer, a gas washer typically uses more water than the electric model.
  • Costly - Both standard and commercial gas pressure washers cost more than its counterparts. If you frequently use your device, the price of fuel can also be expensive.
  • Weight - This machine can be heavy to carry from place to place. There are portable models available with wheels, but they can be difficult to move around.
  • Noise - Like other equipment with a gas-powered engine, this type of pressure washer tends to run loudly.

Electric Pressure Washers

Advantages of Electric Pressure Washers

  • Affordable - An electric pressure washer is typically more affordable than gas models and doesn't require fuel.
  • Lightweight Construction - Most options are light weight, making these devices easy to carry around and use regularly.
  • Low water consumption - An electric model uses fewer gallons per minute than a gas pressure washer, meaning it doesn't consume as much water during operation.
Limitations of Electric Pressure Washers
 
  • Low Power - Due to the limitations of the electric power source, an electric pressure washer might not be able to handle constant usage or heavy-duty tasks.
  • Limited Mobility - While this type of device is lightweight, it has limited range of motion because it must be plugged into a power outlet.
