What should I look for when buying a pressure washer?

When purchasing a pressure washer, consider your cleaning needs.

Different models vary in power and features. Pressure washers can clean anything from exterior surfaces, garden furniture and vehicles. Look for appropriate pressure (measured in bar pressure or PSI), flow rate (litres per hour), and accessories. Consider build quality, brand reputation, and user reviews to ensure you get a reliable and suitable machine for your tasks.

The possibilities for cleaning with a pressure washer are extensive, covering a wide array of outdoor items and surfaces. These surfaces can be categorised into hard surfaces like stone terraces, concrete and metal; medium surfaces like cars and brick walls; and soft surfaces like wood and bicycles.

Pay attention to the hose length to determine its range. Likewise, consider the power cable length to gauge how far it can reach from the power source without an extension. Also, closely consider the pressure washer's size and weight – impacting its portability.

Lastly, examine the included accessories, like brushes, lances, nozzles, hoses, detergents, and wheels. Choose a package that provides specialised lances, surface cleaners and detergents tailored for home and garden cleaning needs.
