How to Choose the Best Pressure Washer for Your Home and Garden

For many Brits, the garden is a source of pride and joy; where hours spent planting flowers and mowing lawns are cherished.

But one element that is often overlooked is the handy pressure washer. This indispensable tool takes on the toughest outdoor cleaning jobs in less time and with far less elbow grease than the average hosepipe and scrubber.

If you are on the lookout for the best pressure washer to spruce up your garden, then you have come to the right place. In this article, we will explore everything from how these machines work to matching the right model to your cleaning tasks, and even offering product recommendations from a trusted source. Let’s dive in.

Why should you use a pressure washer?

A pressure washer, which you may also hear referred to as a power washer or jet washer, is designed to blast away dirt and grime using a concentrated stream of water. 

The charm of the pressure washer is that they save you from back-breaking manual scrubbing. Instead of spending hours working on stubborn stains on patio surfaces, garden furniture, or even the walls of your shed, you can simply direct a high-pressure jet at the problem spots, watching the dirt vanish within seconds. 

Pressure washers are often more water-efficient than a traditional garden hose because the concentrated force of the water increases the cleaning effect without the need for a continuous, high-volume supply.

But their expertise goes beyond cleaning driveways or patios. These machines are equally adept at washing vehicles (under the right settings), garden tools, and even cleaning stubborn debris from outdoor storage areas. 

The range of attachments and adjustable settings on many modern pressure washers means that you can customise the water pressure to suit a variety of surfaces, from delicate garden ornaments to reinforced concrete.

While it may seem like a luxury to own such a machine, the reality is that the modern pressure washer is affordable to buy, and simple to operate. Even if you’re not particularly mechanically inclined, many models are designed with ease of use in mind, with clear instructions and safety mechanisms. 

This makes pressure washers an excellent tool for anyone looking to maintain a pristine home environment without necessarily having professional-grade training.

How do pressure washers work?

How do pressure washers work? It’s an understandable question; and the answer is surprisingly simple.

A pressure washer uses a motor to pump water at high pressure, which is then forced through a narrow nozzle. When water exits through this nozzle, its speed increases dramatically, and the sudden force can dislodge dirt, algae, and other contaminants from surfaces. 

This process is rooted in the basic laws of physics. By reducing the cross-sectional area through the nozzle, the water’s kinetic energy is concentrated into a forceful stream that can tackle even the most stubborn grime.

The key components of a pressure washer include the water inlet valve, water pump, motor, high-pressure hose, and lance. 

First, water enters the machine through the inlet, usually via a standard garden hose, and is directed towards the pump, which accelerates the water, boosting its pressure significantly. 

From there, the water travels along the high-pressure hose to the cleaning attachment, often a lance equipped with a specific nozzle designed to modify the spray pattern.

There are various types of nozzle available, each designed for a particular cleaning purpose. A pencil jet nozzle delivers a narrow, concentrated beam of water that is perfect for precision cleaning, whereas an adjustable fan jet nozzle disperses the water over a wider area, making it ideal for rinsing large surfaces without causing damage.

Different models offer a range of power sources as well. Electric units are popular as they are quiet, lightweight, and typically suitable for a variety of domestic tasks. However, they do require access to a mains power outlet.

For areas where electricity is not readily available, cordless, battery-operated units are gaining popularity. These models, while usually less powerful, offer incredible portability and can be used even in places without an obvious power source. 

Then there are petrol-powered pressure washers, which often have the biggest power levels, making them well-suited for larger or more demanding cleaning projects. These engines are robust and not limited by power cord lengths, but do come with the added weight and noise that typically accompany petrol machines.

Beyond the basic operation, many modern pressure washers feature additional functions. Some models come with a built-in cleaning agent tank, allowing you to mix cleaning chemicals with water for a more effective cleaning process. Others include an auto start/stop function that halts the flow of water once you release the trigger, thereby conserving water.

What to consider when choosing a pressure washer

Before you pick a new pressure washer, you need to make sure you match the machine’s capabilities to your requirements. Here are some points to consider:

What needs cleaning?

Start by evaluating the surfaces and materials that demand attention. Are you mostly looking to clean outdoor patios, garden furniture, or maybe even vehicles? 

Different cleaning tasks require different levels of pressure. For example, lightly soiled items such as bikes or garden ornaments can be effectively cleaned with a low-pressure setting, whereas a heavily discoloured driveway or a patio encrusted with algae will require significantly higher pressure.

How much pressure do you need?

The pressure of a washer is measured in bars, and the figure essentially tells you just how forceful that water jet will be. General guidelines for choosing pressure levels are as follows:

Using too little pressure might mean you spend extra time scrubbing stubborn stains, while too high pressure can damage delicate surfaces. 

Keep in mind that many modern pressure washers offer adjustable pressure settings, so you can dial in just the right amount for every task.

What water flow rate do you require?

The water flow rate is another key performance parameter, as it determines how quickly dirt is washed away from a surface. Generally speaking, a higher flow rate translates to faster cleaning, especially on large surfaces. 

Here’s a brief breakdown:

For domestic users, a medium flow rate is often sufficient. But if you’re dealing with commercial cleaning, where time is of the essence, a high flow rate might be well worth the extra investment.

What type of motor do you need?

For electric pressure washers, the motor’s wattage is an excellent proxy for performance. Typical ranges include:

Larger motors generally deliver higher pressure and flow rates, but also tend to increase both the weight and price of the unit. 

The type of motor plays a big role in the performance and durability of the washer. There are three primary motor types:

• Brush motors: these use electrical brushes that can suffer wear over time and may lower the machine’s overall efficiency.

• Universal motors: typically compact and capable of high speeds, these motors are noisier and have a relatively shorter lifespan.

• Induction motors: more complex and quieter, induction motors benefit from longer life spans, particularly when paired with water-cooling systems that significantly extend their longevity.

What type of power source is best?

Pressure washers come in three main flavours based on their power source.

• Electric pressure washers are usually lighter and quieter, making them a perfect fit for a range of tasks from light to heavy duty. They require a nearby power outlet (preferably an RCD-protected outdoor socket) and can extend their reach via a good outdoor extension lead.

• Battery cordless pressure washers are beloved for their easy portability. They allow you to clean where a fixed power source is lacking. However, they often come with limitations such as lower pressure and flow rates, and their run time is determined by the battery capacity.

• Petrol-powered pressure washers are best for larger or commercial tasks since they operate independent of any external power source, and can deliver impressive power. On the downside, they tend to be heavier and noisier. When using petrol models, it’s important to manage fuel properly. This includes using E10 fuel, draining the tank if stored for over 30 days, or using a stabiliser to keep the fuel in good condition.

Essential pressure washer features

Modern pressure washers come packed with features and accessories that make the process a breeze. Pay close attention to the additional functions and attachments that come with your unit, as these can often be the difference between a good cleaning job and a great one.

Hose length

Pressure washers typically come with hoses of varying lengths, usually from 5m or more. A longer hose is particularly advantageous if you need to cover extensive areas like a sprawling patio or a lengthy driveway. It allows you to work without having to reposition the unit constantly.

Lances and nozzles

The lance is the tool that connects the high-pressure hose to the cleaning task at hand. It usually comes fitted with a trigger gun for activating the water flow, but many lances offer additional adjustments for pressure control. Telescopic lances are especially useful when you need to reach both low and high areas without bending over repeatedly. 

Nozzles come in various forms. Rotary nozzles provide an intense, concentrated stream, while fan jet nozzles distribute water over a larger area. Some models even offer adjustable nozzles that enable you to switch between different spray patterns effortlessly.

Handles and wheels

For heavier or larger pressure washer units, ergonomics is especially very important. 

Look for models with tall or telescopic handles that are comfortable to hold and easy on your back. Wheels will do a lot of the heavy lifting - arguably quite literally on bumpy or uneven ground. Large rubber wheels offer better stability and reduce the strain when transporting the machine from one area of the garden to another. 

Carry handles are also useful if you need to lift the unit onto steps or move it from storage to the work area.

Cleaning agent integration

We mentioned it before, but it really bears repeating. Some pressure washer models offer innovative cleaning agent features, such as integrated tanks or detachable detergent bottles fitted between the lance and the nozzle.

This makes it easy to mix and apply cleaning chemicals directly, which can be a huge time saver when dealing with grease, algae, or stubborn dirt.

Matching the pressure washer to the task

All the considerations and discussions mean nothing if you are unsure what you should use to suit your task. Not every surface or object requires the same intensity of cleaning, so matching your pressure washer’s output will save you a lot of hassle.

Cleaning vehicles

When cleaning cars, you need to remain cautious. Standard cars will be fine on a pressure setting between 90 and 130 bar. But for larger vehicles or commercial transport, the pressure might need to exceed 130 bar. 

With car cleaning, it’s important to use the right attachments. Angled tools or brushes can help maintain a low pressure of around 80 to 130 bar (equivalent to 1200-1900 PSI). 

Start with a pre-rinse, add a suitable shampoo, then wash top-down and finish with a gentle rinse and a microfiber cloth for drying.

Cleaning surfaces

Patios and concrete surfaces present different challenges. Lightly soiled areas can usually be satisfactorily cleaned with a mid-range machine offering 110 to 130 bar and a moderate flow rate.

If you’re facing heavy grime, algae, or oil stains, a machine capable of 130 bar or more will be more efficient. A longer spray lance is particularly helpful here, letting you work without excessive bending or strain.

Paving, whether for domestic gardens or professional settings, also requires considered output. For typical home use, a pressure washer with 110 to 130 bar and a medium flow rate should be good enough.

For frequent, professional daily usage, machines that push 150 bars and deliver a high flow rate, typically at least 420 litres per hour, are ideal. 

Additionally, a patio cleaning attachment can be super handy in this context, diffusing the spray across a wider area and minimising the risk of blasting away the sand that holds paving in place.

Cleaning decking

Decking is another area that calls for careful selection. For cleaning softwood or lightly soiled hardwood decking, a pressure of up to 100 bar is usually safe. 

If the wood is stained or overgrown with algae, stepping up to a setting between 110 and 130 bar may be necessary. Exceeding 130 bar, however, risks damaging the wood grain or splintering the boards. 

Using a 25- or 40-degree nozzle and washing in the direction of the grain, after a pre-soak and the application of a wood-friendly detergent, can help avoid unwanted damage.

Cleaning other outdoor items

Other outdoor items, including bikes, garden furniture, caravans, guttering, and even garden toys, are classed as light duty. 

For these, a pressure washer delivering up to 100 bar with a low flow rate is generally sufficient. Accessories such as telescopic handles or extension poles can make it easier to reach high or awkward areas.
