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.
When you read the reviews take particular note about what customers say about the reliability in particular of the pump. Know that the pump is the most important part of the pressure washer. If you come across reviews that complain about the pump not being reliable you might want to consider another model with a better and more reliable pump. The best pressure washer is not of much use if the pump fails at one point.
