How to Choose the Right Pressure Washer?

Selecting a pressure washer with all the right capabilities for your needs is extremely important.

How much pressure (PSI) do I need?- Lower PSI (pounds per square inch) models are more applicable for general use like cleaning your driveway or car. With the higher PSI models being well suited for heavier commercial applications; like cleaning greasy industrial spaces, floors and machinery.

What Size Pressure Washer do I need?- for commercial, construction, industrial or any other heavy-duty work, a pressure washer of 3500 PSI or higher will suffice. However, for home and light use, a 3000PSI or lower model will generally have all the power you require. Blue Diamond only stocks high powered and high-quality pressure cleaners of 3000PSI and above, so you can be sure that our pressure washers are designed to handle almost any job you throw at them – big or small.

Petrol or Diesel Drive Pressure Washer?- Petrol models are excellent for high power output requirements where the user needs to have the freedom to move around. Diesel pressure washers are generally more fuel efficient in comparison with their petrol pressure washer counterparts and are often the obvious choice for businesses who rely on diesel to run most of their other power equipment e.g. tractors, excavators & other machinery.
