Best Petrol Pressure Washer in the UK in 2022 | Comparison

What is the best petrol pressure washer? Pressure washers have a stream that is dozens of times more powerful as compared to a garden hose. The device works by pressurizing the water, which comes out through a hose attached to the unit. Petrol pressure washers are about two times as powerful and clean the same area three times as fast as electric models. Petrol models are also more durable as their engines are typically made with stronger parts. When choosing your petrol pressure washer, you need to consider three important features: horsepower, maximum flow rate, and water pressure.

How Petrol Pressure Washers Differ

The engine's horsepower rating should be 5HP for homeowners and 6.5HP for professional users. Maximum water pressure is measured in pounds per square inch (PSI) and ranges between 1,000 and 4,000 PSI depending on the model.

• If you only need to clean your car or garden tools, a 1,500 PSI pressure washer will be sufficient.

• To clean the dirt off your patio, choose a unit that features 1,500 to 2,000 PSI, however, mildew and mould require more power. In this case, you should use a 3,000 PSI pressure washer as it is designed to remove tough stains and clean large areas.

• And finally, a pressure washer that produces 3,000 to 4,000 PSI is ultra-powerful and can be used to strip paint or clean concrete.

The PSI value will tell you a lot about the unit’s performance, however, it is not the only factor that influences the water pressure strength. The quality of the pump and the direction of the engine shaft are also something you need to take into consideration. We recommend opting for a pressure washer that comes with a pump made by the manufacturer itself rather than outsourced to a third party. As for the shaft direction, horizontal shafts last longer and are more reliable.

The third feature to consider is the flow rate measured in litres per minute that indicates the amount of water coming out of the unit’s nozzle. The higher the flow rate (11-14 L/min), the faster you will clean the area.

Petrol Pressure Washers Compared

If you are looking for a machine that will cope with almost any task, go for the Wilks-USA TX750i Petrol Power Pressure Washer. This heavy-duty, 40-kilogram machine has a max water pressure of 3950 PSI and a flow rate of 11 litres per minute. Equipped with the Wilks 8HP 4-stroke Engine, the TX750i offers unparalleled performance and reliability.

Rough terrain wheels and a 30-meter hose make this machine easy to manoeuvre despite its heavyweight. Another advantage of this model is that it has a built-in 6-litre detergent tank. And finally, the product comes with an array of accessories, including a self-propelled drain cleaner and a turbo nozzle.

For those who do not need that much power and capacity, we recommend the P1PE P3500PWA Pressure Washer made with the Hyundai IC210 7HP 212cc 4-stroke engine. Although this model is less powerful and efficient than that of the Wilks brand, it is still very fast and effective as compared to many other pressure washers on the market.

The unit delivers a 2990 PSI pressure and a flow rate of 8.7 litres per minute. The 7-meter hose is four times shorter than that of the Wilks model but is sufficient to clean an area adjacent to the house. But if you value portability, this machine will be the best bet for you. It is more lightweight, compact, and has puncture-proof tyres for better mobility.
