Pressure Washer

A pressure washer is an appliance that helps eject water at great pressures which is used primarily for washing purposes. The concept is similar to that of a garden hose, but the pressure that is provided by a pressure washer is significantly greater than that of a garden hose, most times from 15 to 50 times higher or even more. The high pressure with which the water is ejected helps in the removal of embedded dirt and other matter and making the surface cleaner than regular cleaning methods can provide. They are so effective at cleaning that they can even remove graffiti from walls, sometimes to a greater extent than the cleaning would actually warrant, leaving permanent scars on the walls.

Most pressure washers are connected to the garden hose to get their supply of water. There is an important point to note while inputting water to a pressure washer. The source of water must provide at least or more water than the pressure washer is set to draw. If the source does not provide as much water as the pressure water can take, it can damage the pressure washer and even lead to accidents.

When water is ejected through a garden hose, it is released at a greater pressure than at the source. This pressure is regulated by the nozzle that is fitted at the end of the garden hose. However, a pressure washer can provide much more pressure than what this mere nozzle can provide. Pressure washers have nozzles too, which can eject water in thin streams or with a more spread-out triangulated stream, but the main pressure that is provided by the pressure washer is because of a pump.

The pump present in the main body of the pressure washer compresses the water that is fed into it and releases it under high pressure. This water won’t be released until and unless the user opens a valve that is attached to the hose of the pressure washer. There are various ways in which the user can have the water get ejected from the hose. It can also be triggered to make the water come out in a continuous form or in the form of short staccato bursts.

There are basically two types of pressure washers depending on the kind of water that they can generate. Some of the pressure washers eject water at its normal temperature. These are called as cold pressure washers. Yet others can heat the water as they eject it. These pressure washers are commonly known as hot pressure washers. Hot pressure washers are more effective than cold pressure washers; however, they are also more expensive than the cold ones.

Again, there are two kinds of pressure washers based on the kind of energy source they require for their function. These are the gas powered ones and the electrical ones. The gas powered ones require gases such as natural gas for their operation. These are much more effective for cleaning because the pressures that they can provide are considerably higher. Electrical pressure washers are used for moderate cleaning requirements where using the gas washers could be dangerous. For example, when washing a glass surface, electric pressure washers could be ideally used.

Most pressure washers are used in industrial setups. These were used to clean surfaces and other such jobs connected to industries. There was a very low demand for them in the household market. However, with reducing prices and, most importantly, reducing sizes, the pressure washers have become more acceptable in the household market. The pressure produced by a pressure washer is directly dependent on the size of the machine, but for residential cleaning purposes, even moderately-sized pressure washers can do a very satisfactory job.
