High Pressure Washer FAQ's

What Is a High Pressure Washer?

Pressure washers are part garden hose and part air compressor. A typical pressure washer has either a gas-fueled engine or electrical powered motor that powers a water pump. The pump accelerates the water, supplied from a garden hose, to produce high pressure. The washer is hooked to a high pressure-rated hose. At the end of the hose is a water gun that looks similar to the pressure guns used at car washes. When the trigger is pulled, the water mixes with the air and comes out of the nozzle. Pressure washers can aggressively blast things clean with water jets pressurized at about 75 times the pressure of a garden hose. Or, they can gently spray with lower pressures for delicate cleaning.

Why Choose a High Pressure Washer?

Pressure washers are typically used to clean hard surfaces across industrial, commercial and construction applications and for homes. Suppose you are unsure which pressure washer is best? In that case, our professional pressure washer sales team is ready to provide expert advice and guidance, ensuring you choose the right pressure washer to meet your needs. Our range includes both petrol and diesel high pressure washers.

What Are High Pressure Washers Used For?

Pressure washers use narrow, high-pressure jets of water, often mixed with soaps or detergents, that actively break down dirt and debris, to clean hard surfaces without using abrasive techniques. Pressure washers can be used for a variety of home and commercial uses like cleaning the BBQ, garage floors, front entrance ways, fences, gutters and vehicles.

How Does a Pressure Washer Work?

A high pressure washer connects to the garden tap (or a bucket or water tank) and reduces the water flow while amplifying the pressure, which is then released in a hard jet when you pull the trigger.

How Much Water Do Pressure Washers Use?

An average high pressure washer uses approximately 8 gallons (30.28 Litres) of water per minute. On the other hand, an average garden hose uses 12 to 13 gallons (45 to 49 Litres) per minute. Many high pressure washers feature an automatic shut-off valve which prevents the continuous flow of water while in use.

Which High Pressure Washer To Buy?

Most petrol machines are on four wheels, making them manoeuvrable and unrestricted by their power source. This means paired with a water tank, they can be used remotely or moved around between cleaning jobs. This does however make them heavier than electric machines because they need to carry around their own fuel, and if used remotely their water supply as well. On the other hand, diesel pressure washers have fuel efficiency as an advantage. Although diesel might be more expensive to purchase it lasts a lot longer than petrol and can be running for hours on end. They also tend to have a higher flow rate and more powerful engines, minimising cleaning times. This means diesel pressure washers are most common for industrial applications.
