Top rated gas pressure washers

Muck, grime, dirty driveways and patios, nasty oil spills in the garage, that’s part of everyday life. However, there’s an easy way to deal with dirty surfaces and the hard way. Since you landed here on the best gas pressure washer and Top rated gas pressure washers page, that means you already know about the easy way.

Pressure washers can be powered by a gasoline engine or an electric motor, and there are clear differences between these two types of pressure washers. We will explore them all in detail, focusing on the gasoline-powered washers and their superiority.

The choice for a suitable gas pressure washer becomes easy once you know the important things to consider. So, take a look below:

1. Pressure

Without appropriate pressure, it is not possible to thoroughly clean any surface. The gas pressure washers are equipped with the mechanism to employ high pressure for thorough cleaning. With the assistance of gas pressure output, any kind of dirt is effectively eliminated.

In most of the above-discussed gas pressure washer models, the pressure (in PSI) found is in the range of 2500-3300 PSI. The pressure in this range is enough for different kinds of cleaning applications. With the help of this pressure output, the device can effectively clean any dirt.

2. Flow rate

The flow rate denotes the Gallons of water flow per minute. It is measured in GPM (gallons per minute). This unit measures the water supply by the pump of your gas pressure washer. For thorough cleaning, the GPM must be high. Generally, you will find GPM in the range of 2-2.5 in all the discussed gas pressure washers in this article.

3. Construction

The construction of the carriage frame and overall construction plays a vital role in deciding a gas pressure washer. The powerful units come with the wheelbarrow stance to make more space for the larger engine and pump. Moreover, the frame is welded steel and must be equipped with the vibration isolator engine mounting.

4.  Manufacturing design

The quality parts and manufacturing design both matters when choosing a gas pressure washer. You don’t want the unit to just have a high PSI, high flow rate, and a powerful engine. Besides, it is important to make sure it is constructed the quality parts and quality manufacturing design. This makes sure it can seamlessly withstand the rigors of different types of jobs.

Whether you want to use your gas pressure washer for residential jobs or want to take it to construction job sites, make sure the body is suitable for heavy-duty use. Make sure the materials used to hold up long-term use. Usually, the stamped steel parts are good and they can hold up well for different applications. Welded steel is even better.

5. Fuel Efficiency

Your chosen gas pressure washer should be fuel-efficient and produce low emission. Generally, gas prices are high in recent times, so fuel efficiency must be high. If you intend to use your gas pressure washer frequently, then the fuel efficiency must be high. It should not burn excessive fuel.

The higher fuel efficiency directly indicates reduced carbon emissions. For the residential purpose and small businesses, the fuel emission must be lower. Try to find the gas pressure washer model equipped with a powerful engine with high fuel efficiency.

6. Portability

In addition to the cleaning power and build quality, one more essential aspect to consider is portability. It is essential to pick a model that can be easily carried along. Fortunately, the top quality gas pressure washers come with huge diameter wheels that provide excellent portability. So, it is easy to move them around your backyard without any hassles.

7.  Additional features

A gas pressure washer becomes easier to use if it comes with thoughtful design features. It must be equipped with a crank-operated mechanism for rolling the hose and a compartment dedicated to the storage of the spray wand. This wand must have plenty of options for altering the PSI as per the need. This means that it must come with multiple spray nozzles.

Another additional feature to consider is the onboard reservoir for chemical solvents or detergents. The presence of dial is one more additional feature. You can use it to vary the level of soap entering inside the water spray. Furthermore, it must have a wide range of options for flow rates and temperature.

8. Price

For gas pressure washers, you get what you pay for holds true. These units are available at a budget-friendly price and an expensive price too. There are very few brand-new gas pressure washers that come at less than $300.  The price range of $300 – $500 is the most popular. Most of the heavy-duty units are available in this range. Generally, these units boast twice or thrice the cleaning power than the common electric washers.
