However, to buy a good one is a BIG challenge since there are many options in the market.
So, we are here to show you the best gas pressure washer reviews that have explained the significant features of each model that can fit any needs. As long as you follow us from the beginning, you won’t wonder which one is the best pick.
If you are ready to discover this kind of machine thoroughly, please down here now.
What is the Gas Pressure Washer?
As its name suggests, this unit helps clean a variety of surfaces via using water pressure. It is designed to take power in two different forms of gasoline including diesel and petrol and then operate the engine.
In case you prefer the most powerful engine, the diesel-powered one is ideal. But remember that it will be more expensive and noisier.
Generally, the gas pressure washer is durable, can provide more power, and remove any type of mess with ease.
Although it is a bit heavy, it is designed with the firm and treaded wheels. This means you can move this unit around no matter what the terrain is.
Advantages and Disadvantages of the Gas Pressure Washer
Advantages
One of the most excellent features that the best gas-powered power washer offers is its high pressure.
While the pressure of a garden hose can increase the water pressure between 10 psi and 40 psi, the gas pressure water can deliver pressures of over 3,000 psi or even up to 4,000 psi.
Relying on that, your cleaning jobs in larger places will become easier.
Another good point is that this unit allows you not to use detergent for cleaning. All you just do is to select a hot water option and then clean any substance from any surfaces without using the chemicals.
Since the gas pressure washer doesn’t ask for a power source or extension cords, they are more movable and excellent for outdoor uses.
Disadvantages
Although the mobility of the gas-powered pressure washers is a highlight, their weight is an issue for moving around.
Compared to the electric pressure washers, the gas pressure one is louder. So, if you are going to use it often while living in a residential place, it will not be a good choice.
Additionally, this machine requires maintenance such as oil changes, tune-ups, etc. quite often.
And if it idles for a long time, you have to winterize and stabilize it by checking oil levels and taking care of the fuel in the tank. Make sure you prime certain engines repeatedly so that you get a good start.
Last but not least, the cost you have to pay when using this machine is quite pricey. In case you have a limited budget, you should reconsider.
How to Choose the Best Gas Pressure Washer?
Before diving into a deep review of the top 12 gas pressure washers below, there are some important things that you should not miss.
Read them carefully because this makes a BIG difference between your well-spent money and a machine that is lying around in the warehouse.
Water pressure power
The power source of a gas pressure washer is defined by Cleaning Power Units (CPU), Pounds per square inch (PSI), and Gallons per minute (GPM).
The greater the CPU is, the greater the capacity the washer has for cleaning effectively and deeply. But buyers often focus on the PSI and ignore the CPU.
Let’s explain carefully!
CPU = PSI x GPM
For instance, a gas-powered pressure washer might have 2 GPM and 2800 PSI, giving a CPU of 5600. Meanwhile, another machine has only 2400 PSI yet has 3 GMP, giving a CPU of 7200.
As you see, the unit with the lower PSI has over 20% greater cleaning power than the one with higher PSI.
Hence, it’s best to check the CPU rating to find the machine you want.
Pump type
The next important thing is to determine the type of pump.
- A wobble pump has a plate that is linked with a drive shaft. And it is forced to wobble by pistons pushing against it. This type is quite inefficient (about 70% because of piston spring struggle on each stroke)
- An axial pump comes with a larger bearing and an oil reservoir, allowing the pump to operate cooler and last longer. It also creates more PSI and GPM thanks to the wobble pump.
- A triplex pump features three piston rods that can go together for producing smoother pressurization as well as lessening pulsation. Moreover, it creates much less heat and operates cooler than the axial pump, giving maximum durability. But the cost is pricey.
Engine
The engine of a gas-powered pressure engine is the main power source that runs the pump. That means the greater the engine pumps (rated in HP), the greater the PSI and GPM could be produced.
And to determine the good engine, you need to check how much horsepower it has and how many hours it is rated for.
Keep in mind that the better quality the engine is, the longer it will last.
Portability
How easy will a gas pressure washer be for you to move around as well as store it?
Of course, we don’t want to end up unsatisfied when buying the machine that wheeling it from one place to another is a challenge.
So, it’s best to find a washer with wheels that should be at least 10-inch for rolling on any terrain with ease.
Ease of use
Is the setup easy or do you need to understand intricate steps to get the washer to start?
The gas pressure washers are advertised as an easy-to-use machine. Make sure you read instructions carefully to run it correctly.
Additionally, this unit requires frequent maintenance as compared to electric ones. Even if you don’t use it for a long time, you have to winterize it well.
Price and warranty
Most customers want a cheap yet effective gas pressure washer. But our suggestion is to know your needs first.
If you want a powerful machine for heavy-duty cleaning, you should invest your money. On the contrary, going for an affordable one that is good value for your money is okay.
In terms of the warranty, keep in mind that it is divided into two different categories including one for the engine and one for the pump. And if the bigger the warranty is, the better you can get.
