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.
To reduce uncertainty ascertain how long the washer would be used each week and how hard it would have to work. To have a washer working at full tilt all the time will not improve its longevity. It is also important to think about the kind of cleaning required is the dirt caked on? Do you want to clean large floor areas or smaller pieces of equipment. Do you need a hot or cold water version?
