Pressure washers (jet washers) are an invaluable cleaning tool and like many things once you have used one you will wonder how you managed without it but what is a pressure washer? It basically comprises a pump a high pressure hose and a cleaning lance with a trigger switch. Water is passed through the machine and put under pressure by the pump and expelled via the hose and out from the nozzle at the end of the lance. On the face of it quite a simple machine but selecting the right pressure washer is a different matter.
The capacity and consumption of fuel to feed the burner. Most hot water pressure washers have a boiler which is normally heated by a burner using kerosene. The fuel tank capacity and consumption shows how long the machine can run before refilling. On diesel powered machines the fuel tank will normally power the pump and the burner.
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?
