Pressure alone is not an indication of effective cleaning as water volume plays an important part. For instance high pressure used with a low water volume will produce a powerful but narrow water jet which may be ideal for cleaning small areas of ingrained dirt but not so effective for cleaning larger areas with a lot of debris to be removed. In this situation a pressure washer with a larger water volume cleans more efficiently.

Hot water pressure washers are also available with electrically heated boilers which offer limited temperatures. These machines are normally used where using kerosene is not an option. Deciding on which pressure to buy or hire is complex. This relationship between water flow and pressure is important depending on the type of cleaning being carried out. Reading the technical specification of a washer is fine but is the pump of good quality? Is the hose of the correct rating for the machine and is it long enough for your needs?
