Gas vs. Electric Power Washer: Which one is better?

gas vs electric pressure washer

Power washers are handy for cleaning your home or business. If you’re in the market for a new power washer, you’re probably searching for a suitable model to fit your needs. 

There is a lot to choose from, but it can get confusing as to which power washer is better. Gas or electricity is a question that can be difficult to answer. 

This blog will help you understand the differences between gas and electric power washers and help you make the best decision for your needs.

Why Do You Need A Power Washer?

A power washer is an essential tool for maintaining your home and property. It performs the difficult work of getting rid of stubborn dirt, mold, mildew, and other grime that would otherwise be difficult to clean without harsh chemicals. 

A power washer can also be used on decks, siding, gutters, and windowsills to make them look new again. It offers a solution for those who don’t want to spend all their time cleaning.

However, people may not always think about the need for a power washer. 

It might come up because of a request from a contractor or to do the annual spring cleaning, but it is easy to dismiss this device as unnecessary. 

The truth is that a power washer can be a lifesaver when preparing surfaces for painting, removing mold and grime from bricks and stone, removing dirt from cement floors, and so much more!

So that’s the reason why you should have your power washer at home.

The Difference Between The Two

There is a big difference between gas power washers and electric power washers in their features and uses.

Here, we’ll discuss the differences between the two products to determine better to use.

The Price

While gas power washers are more powerful, they also come at a higher price.

Gas Power Washer engines are expensive and need maintenance, which can be difficult in certain areas or if the user is inexperienced. 

However, there is no recoil from the engine to exhaust the system with an electric power washer, and it is much quieter when operating. 

These benefits make an electric power washer a better choice for homeowners in many cases.

Regarding when it uses

For instance, Electric power washers are easier to start and can be used in enclosed spaces. 

One of the main advantages of an electric power washer is that it will start up quickly and easily. 

In contrast, Gas powered engine-driven units have a higher power-to-weight ratio, but they need a large area to run safely and not start unless gasoline is available. 

It also requires more maintenance than an electric pressure washer because multiple moving parts wear out over time.

Since gas power washers produce carbon monoxide, which is very toxic and can’t be noticed easily, it is advised to use a gas power washer outside rather than inside your house.

Regarding the noise produce

Gas pressure washers are known to be louder than their electric counterparts. This is due to the emissions created by gas models. 

The noise produced by gas models is comparable to an idling diesel engine at full power. On the other hand, electric power washers create gentle whirls and hums, like many household appliances.

A gas pressure washer emits more emissions than an electric counterpart.

When it comes to their role, gas pressure washers are better for heavier duty jobs like cleaning concrete or removing oil stains from asphalt. 

In contrast, electric power washers are more environmentally friendly with lower noise levels, although less powerful.


Electric power washers are better for those who want to spend less time maintaining their pressure washer. It requires lubrication for the pump and cleaning it generally so the cooling filter will never block.

In contrast, gas-powered pressure washers need regular maintenance, which requires the user to drain and replace the engine oil, change the air filter, and change the spark plugs at least once per year.


Gas pressure washers can produce more pressure, approximately 2,500 to 4,000 PSI, than electric power washers which have only 1,500 to 3,000 pounds per square inch. 

The increased pressure makes them capable of cleaning surfaces that are rougher, dirtier, and with more grease than electric water-pressure cleaners can handle. 

Therefore, gas-powered units are the most suitable when you need a more potent blast of water to remove tough stains or dirt from multiple surfaces due to their higher PSI.

Pros and Cons

This time, let’s talk about the pros and cons of each type of power washer featured in this article. 

Both of them are good to use in cleaning surfaces, but each has some advantages and disadvantages to the user.

Let’s found out!

Product Pros Cons
Gas Power Washer
  • High PSI rather than electric. Good for heavy-duty cleaning.
  • No need for a cleaning agent to clean the surface because of its high pressure.
  • It cleans the surface in a quicker time.
  • Easy to maneuver because they have steel frames with wheels for easy portability.
  • Very durable.
  • Heavy and noisy
  • Need a fuel to operate which is very costly.
  • More dangerous because it emits fuel. Not eco-friendly.
  • Very expensive.
Electric Power Washer
  • Great for light-duty cleaning in patio, decking, siding, and cars.
  • The amount of pressure is enough to do a good cleaning without damage.
  • Lightweight and very simple to maneuver.
  • Easily stored because it is compact.
  • Eco-friendly equipment.
  • Very cheap and affordable.
  • No need for fuel to operate.
  • Less power than gas.
  • Not durable.
  • Need electric power to operate.

So, which one is better?

Choosing the best power washer between the two is very challenging. 

Hence, in conclusion, electric power washers are a viable option for saving money and conserving their energy sources. 

Electric power washers use less water, produce lower sound levels, and have longer battery life. 

However, if you want the best quality power washing job, I recommend you to choose the gas-powered washer since it is more powerful to do heavy cleaning jobs because of its high pressure.

With so many power washer options out there can sometimes be overwhelming, but reading this blog post should help you find the best power washer for you.
