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.
For instance do you want a hot or cold water pressure washer. In most situations a cold water version is adequate but a hot water washer with an integral boiler will remove stubborn residue more easily (just think about doing the washing up – hot water is much more effective). For even more cleaning power a hot water jet washer can have a facility to make steam which is achieved by a valve reducing the water flow into the boiler causing steam to be formed when leaving the lance. Steam is useful for cleaning very stubborn deposits as well as killing bacteria.
