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.
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?
One solution might be to hire a pressure washer before buying and ask a company expert in the field what they recommend. Don’t forget to factor in to your costings any servicing that may be required to make sure the washer will work at optimum efficiency.
