Pressure washers also have options of hot and cold water usage. Not all have both hot and cold water facility. Hot water cleaning can be used for more effective and perfect cleaning in places where dirt and grease are predominant and quite stubborn. However hot water washers are expensive to the normal washers and so can be bought in case the feature is useful. The measure of the pressure in which the water shoots from such a washer is called a PSI or the Pounds per Square Inch. The higher the PSI the greater the pressure of the water being shot from the machine. 3000-4000 PSI is quite a good measure for such washers.
The first thing you need to know is about the different types of pressure washer available on the market today. Look at your own needs and requirements and what the main purpose will be. The kind of washer you want to get will depend on what you actually want. Obviously the greater the pressure the better the ability to clean effectively. If you need a really strong one the obvious choice is a washer powered by gasoline as it gains more horsepower than one powered by electricity. On the other hand if you do not need a super strong washer you can get an electrical one. Those types can be suitable for more moderate tasks such as removing the dust and grime from windows garden furniture and similar items.
