The water broom and nozzles manufactured for use in conjunction with Generac’s OneWash power washer, model number 6602, merely attach to the product’s lance, much like the other nozzles otherwise provided with the unit. If you are uncertain as to how to appropriately attach any lance-based connections, please do not hesitate to contact us directly at 888-GENERAC (436-3722).

Answer this question

Answers
answer 1
The OneWash power washer is designed to utilize one of 3 provided nozzles. Detergent can be applied with the soap applicator nozzle. The 25° “wash” nozzle has a pressure range between 2000psi to 2600psi, and is suitable for cleaning surfaces between one or two story heights. Please note that as the distance between the nozzle and the cleaning surface increases, the cleaning power decreases. The red 0° “blast” nozzle delivers up to 3000psi, but is only meant to be used on the brick/concrete application setting to remove stubborn stains from masonry and concrete surfaces. This red nozzle is used infrequently and should be used with caution, as it can cause unintentional damage to surfaces. Any damage caused by misuse or incorrect settings are not covered under the manufacturer’s warranty.
