5 Things You Need to Know When Buying a Petrol Pressure Washer

Petrol Pressure washers

Pressure washers are powerful tools and are great for a range of heavy-duty cleaning jobs. They are used for everything from graffiti removal to boat cleaning, and they can inject water at high pressure. Some pressure washers have low-pressure nozzles, which are perfect for light cleaning jobs like removing dirt and grime. Others are powerful enough to strip paint off surfaces. It’s important that you choose a pressure washer that is appropriate for your skill level and the job you want to do.

Choosing between a pressure washer is never an easy task. But before you make your choice, you need to consider what you will use it for. Will you clean cars or boats? How about the home’s driveway and front façade? You need to be sure of your requirements and needs. The wrong pressure washer simply won’t do. Once you’ve found what works and what doesn’t, you can then choose a pressure washer.

It’s important to consider three major factors when shopping for a petrol pressure washer. You should also consider three minor features that might not seem important but matters a lot if you’re going to use your pressure washer for professional purposes.


For petrol pressure washers, you’ll want to pay close attention to the engine horsepower. The HP rating of the engine determines the volume and pressure capacity of the machine. Some cheaper models advertise a higher pressure rating without increasing the engine HP. The two should be in balance.

When buying a pressure washer, you should look at the HP, PSI and GPM. Most domestic users should get a pressure washer with 5HP, but if you want to wash vehicles then you can get away with less. Professional users should get a pressure washer with at least 6.5HP for typical work, but it depends on the type of work. Some people prefer commercial-grade pressure washers, but these are only for workshops and manufacturing plants.


Pressure washers use a measurement called GPM, or gallons per minute, to determine how much water the machine can discharge per minute. Along with the PSI rating, GPM is one of the best indicators of how effective a pressure washer is.


Pressure is measured in PSI or pounds per square inch. This is the least important measurement, but it’s still an important factor of pressure washer performance. One of the best ways to measure the pressure washer power is to multiply the PSI with GPM. These two measurements together show how powerful a machine might be.


When choosing a pressure washer, always ask if the pump is built by the manufacturer or outsourced to a third-party supplier. Your best bet is to choose a model from a good brand. You might think you’re saving by buying a cheap pressure washer, but you’ll be disappointed by its performance, reduced service life and difficulty in accessing spare parts. Don’t forget to check the pump’s components as well — there are some telltale signs that it’s a high-quality pump.

Vertical or Horizontal Shaft

One of the less known factors to consider when buying a pressure washer is the direction of the engine shaft. For vertical shafts, the engine will often be more affordable but has a shorter service life. Meanwhile horizontal shafts tend to be more expensive with a longer service life. If you want your pressure washer to last for a long time, then you should buy one which has a horizontal shaft.
