How much power do I need for my jobs?

   Power is considered in two ways with pressure cleaning. There is the pressure of the water coming out the pump and the flow, or gallons per minute, that comes out of the pump to consider. Both of these factors influence the cleaning power of the unit. Car washing, or cleaning wood decks requires lower PSI so as not to damage the surface, so higher gallons per minute are required for cleaning ability. This is true for any delicate or semi delicate surface that needs to be cleaned. Concrete and asphalt can handle higher pressures, so lower flow rates can be used to clean the surfaces. Total machine power can be approximated by multiplying the pressure by the flow rate to give an overall power rating (cleaning units). This is helpful, but always consider which surface is to be cleaned to choose the specifications of your unit.
