The 5 Best Petrol Water Blaster NZ

When it comes to cleaning your garden, the best tool is a powerful petrol water blaster. This high-powered tool will cut through grease, grime, and more, leaving your garden fresh, clean, and smudge-free. 

Most pressure washers have a stream that is 50 times more powerful than water coming out of a garden hose. When combined with detergent, this enables the washer to remove everything from dirt to the sticky sap on your hands. The best petrol water blasters are actually using less water as compared to garden hoses.

As with all tools, there are considerations that must be made before selecting a pressure washer and there are many to choose from. In this blog, we will discuss the best types of pressure washers, what they do, and what aspects of the different pressure washers should be considered before purchasing.

How to choose the Best Petrol Water Blaster for you

Here are some of the important factors to consider when choosing the best petrol water blasters:


How much power a washer can produce?

Power is the first consideration when identifying the best petrol water blasters for you. The higher the power, the better it will be to clean larger areas. While smaller washers may be sufficient for occasional or light use, you will want to consider a more powerful one if you need to clean an extensive area. Most of these larger power pressure washers are gas-powered as they hold more power and are more efficient.

A pressure washer can generate between 4 and 15 horsepower. A higher number of horses may be more powerful, but the pressure washer will take more fuel to produce the same amount of power. Also, there is a direct correlation between how much power a pressure washer holds and its price. 


How much psi (PSI) is required?

When looking for a high pounds per square inch (psi) pressure washer, consider the types of cleaning you plan to do. A high psi pressure washer will provide more power than a low psi washer, but be careful not to go over the limit.

Here is a general psi range usage:

  • Home cleaning: 2,000 psi or more
  • Light duty tasks: 2,400-3,000 psi
  • Medium duty tasks: 3,500-5,000 psi

The higher end of the scale typically has more water flow and a larger engine. Make sure to use proper gear and protective clothing when using high-pressure washers.


What other things need to consider?

Portability: This is probably the most important aspect of a pressure washer. The one that you choose must be easy to move around, whether it’s by hand or in a vehicle, and into the places where you need it. Make sure the wheels are  25 cm+ in size to ensure you can easily move them around.

Hose length: The hose length must be between 3 meters to 5 meters in order to make sure you have enough distance to clean every part of your garden and house.

Changeable Nozzles: Look for the best petrol water blasters with changeable nozzles so you can adjust the flow of water as needed. This is also good if you want different types of sprays, such as a fine mist or solid stream.

Safety features: There are some safety features that you should consider when purchasing a pressure washer. Look for the best petrol water blasters with an automatic shut-off function in case the trigger is released mid-spray.

Detergent tank: Look for a pressure washer with an inbuilt detergent tank to help you avoid the hassle of mixing, storing, and applying the correct amount of detergent.

Adjustable Pressure Options: A pressure washer with a range between 500 to 3,000 PSI is ideal for almost all households and gardens. They are simple to adjust and offer this degree of pressure at a low cost.

How does a petrol water blaster work?

Petrol pressure washers work on the same principle as in a jet engine. A jet engine uses a compressor to draw air into its chamber where it combusts and creates an internal pressure between 50-150 psi. The compression chamber causes the air to be forced out of the exhaust of the jet engine, resulting in propulsion power. This is exactly how petrol pressure washers work.


Which is better Petrol or Electric washers?

They each have their advantages and disadvantages. Petrol washers are generally more powerful than Electric washers, but they are also the noisier and, obviously, the ones you need to be careful with. Electric washers are quieter, safer and can power through the dirt of all kinds. Each has its uses; it really comes down to what you need.


What PSI is good for a water blaster?

Pressure washers with a PSI of 2000 or more are the most effective for household jobs. Some residential units shoot at about 2800 PSI. When buying a pressure washer, you should consider the size of the cleaning job you plan on doing. 

The higher the PSI, the more power and force it has to remove tough dirt. Professional pressure washers run much higher than average household pressure washers and may run as high as 3000-4000 PSI depending on your needs.


Can you use a water blaster on a car?

A pressure washer is basically the same as a water blaster or garden hose with a high-powered nozzle. The main difference between a pressure washer for your car and your garden is nozzle size, PSI (pressure per square inch), and gallons per minute. Make sure the pressure on the best petrol water blasters is set to a level that won’t damage car paint.
