Power Washer

Understanding Types and Uses of Power Washers

The concept of a power washer is readily understandable if you think of a garden hose and the difference made when the aperture of the spay nozzle is reduced causing the water to be expelled at a faster rate and in a narrower jet. In this case the water pressure is determined by the mains water supply whereas in a power or pressure washer an integral pump creates the pressure under which the water is placed until it is emitted. This principle is used to create a variety of machines where pressure and water volume are controlled so that they are suitable for the cleaning job in hand. For instance if dried on paint or graffiti was to be removed then a high water volume with high pressure would be required. However, for a large area of pavement a lower pressure used in conjunction with a high water volume would be preferred, for effective cleaning without wasting water. These two examples show the versatility of the power washer which is why it is an invaluable tool in the field of industrial cleaning.

Cold Water Power Washer

For many applications a cold water power washer is sufficient. They vary in size and can be portable or static and powered by electricity or their own power source. For smaller jobs, a portable washer with a plug in lead may be adequate. However, movement is restricted by the length of the lead, therefore if the power washer is required for work elsewhere or off site then a washer with its own diesel or petrol engine would be better. In some situations a static washer is the best option as, if the cleaning duty is known and regular, the machine can be controlled more easily and there is less opportunity for operator abuse.

Hot Water Power Washer

Where the cleaning requirement is heavier then a hot water power washer is a better option, as cleaning is more efficient with hot water and any detergents used to aid cleaning would be more effective. The principles are the same as a cold water power washer except that a boiler is integral to the unit to heat the water, so the unit can be portable or static. An additional feature of some hot water power washers is that they can have a steam facility built in where the water pressure is lowered and the boiler allowed to heat the water until steam is produced. This is useful where additional cleaning muscle is required, although if deep sanitizing is required a propriety steam cleaner is a better option.
