Another important feature is the inclusion of various nozzle types. Most pressure washers come with interchangeable nozzles that allow you to switch between narrow and wide spray patterns. A wide-angle nozzle is perfect for rinsing large surfaces, while a narrow nozzle can help target tough spots. A foam cannon attachment is also a fantastic addition, as it allows you to apply soap evenly and generously over the vehicle surface, enhancing the cleaning process.

The design of the volute is crucial for the efficiency of the pump. A well-designed volute minimizes flow separation and turbulence, ensuring a smooth transition of the fluid from the impeller to the discharge pipe. The volute shape is typically spiral, which facilitates a uniform flow distribution. If the volute is improperly designed, it can lead to inefficiencies such as cavitation, vibrations, and noise, significantly affecting the pump's overall performance.
