Using the wrong nozzle can cause decreased efficiency or even damage the machine. Therefore, users must refer to their pressure washer's manual to ensure they select the appropriate pressure washer spray nozzle.

In addition to the standard nozzles, there are also specialized attachments available for pressure washer spray nozzles. Turbo nozzles, for example, combine the power of a 0° nozzle with the coverage of a wider spray, making them ideal for tough cleaning tasks. These nozzles rotate as they spray, providing a more efficient cleaning action. Furthermore, foam cannons can be attached to pressure washer spray nozzles to create thick foam for enhanced cleaning, particularly useful in automotive detailing.

Safety is another critical consideration when using pressure washer spray nozzles. The high-pressure water streams can cause injury if not handled properly. Users should always wear protective gear and maintain a safe distance from the surface being cleaned. Understanding the capabilities and limitations of each type of washer spray nozzle can help prevent accidents and ensure effective cleaning.
