What is a pressure washer?

Pressure Washing concrete

A pressure washer is a machine that uses highly pressurised water jets to eliminate hard-to-remove grime and dirt in situations where detergent just doesn’t cut it. These jets are capable of producing pressures ranging from 750 to 10,000 PSI (Pounds per Square Inch) to take care of any blemish on the outside of your home, with commercial models additionally available with higher PSI output to help clean surfaces like machinery.

Pressure washers primarily work through two components – the pump and the motor. The motor – either an electrical or gas model – powers the pump, which in turn accelerates and pressurises the water, which then comes out of the jets at a higher output, allowing you to achieve a deeper clean, or to tackle those tough stains and marks. Depending on the model, you can simply attach your hose into the input of your pressure washer to feed it, with the pressure washer doing the rest.

Types of pressure washers

While you could be forgiven for thinking that all pressure washers do the same thing, there are actually a few key differences you should be aware of to ensure that you’re getting the best clean possible and that you don’t accidently strip away any paint. After all, pressure washers can pack a punch!

This type of pressure washers has a coil that heats up the water to a certain temperature, with hot water pressure washers also generally more powerful in terms of PSI output, and are generally more expensive as a result.

What to consider when buying a pressure washer

While pressure washers are all built to do the same thing, there are a few areas that you should consider before parting with your hard-earned dollars. Here is what you should consider before buying a pressure washer:

  • Power: Pressurised water is an easy way to clean surfaces, but can also be an easy way to ruin them as well if you aren’t careful. As a result, it’s best to look into how much PSI a pressure washer packs, and think about what type of surface you’re cleaning. For example, concrete can take a higher PSI than paint, meaning if you’re looking to lightly clean without ruining your paint job, a pressure washer with a lower PSI capability – or at least a different nozzle – will be your better option.
  • Type: Gas models are generally more powerful than electric models, meaning you can cut through dirt and grime quicker, but are also more expensive, and are generally noisier as a result. So if you’re looking to clean the outside of the house of a Sunday morning, your neighbours might prefer you pick up an electric model.
  • Features: Some pressure washers come with a soap tank to you help give your exterior a good bath, with other models coming equipped with wheels for portability. Adjustable nozzles will also help you tackle stains and grime, meaning looking into what comes with your pressure washer can make the cleaning job that much easier.
  • Price: As with any purchase, the price tag can be a big factor in which brand and model you walk out the door with. But while you may get more power and more features with a larger price tag, that doesn’t always mean you’re getting good value for money, meaning thinking about what you’re actually going to be using your pressure washer for, and how often you’re going to be using it, will help you determine how much money you’re willing to spend.

How much does a pressure washer cost?

Pressure washers can cost anywhere from $50 to $2,000, but with a larger price tag comes a larger PSI output, meaning if you’re looking to clean off a light layer of dust, a cheaper, less powerful model may do the trick, but if you’re looking to really give your house a face-lift, a more expensive model may be your best bet.

Where can I buy a pressure washer?

Pressure washers are available for purchase both online and in-store at hardware retailers such as Bunnings and online retailers such as Kogan, as well as through the brand directly, giving you plenty of options to choose from.

But with plenty of brands, models and types on the market, it’s best to look into all of your options before buying, allowing you to clean up your house without cleaning out your bank account.
