Pressure washers or power washers are power cleaners. The powerful spray of water coming from a pressure washer ensures effective cleaning of any kind of surface- wood, concrete, glass or fiber. The main component in a pressure washer is the pump, which creates water pressure inside the machine. This pressure can be adjusted according to the need. The hose contains a trigger, which allows for adjusting the pressure of the water further from short bursts to a continuous spray.

Some pressure washers are 100 percent more powerful than a normal garden hose. Pressure washers are especially effective in removing stubborn stains, grime and dust. Hot water pressure washers are ideal for places such as garages, industrial plants, food processing plants, agriculture machineries, and airport environments.

Pressure washers generally use gasoline and diesel. There are also hydraulic and electrical pressure washers. Pressure washers are also classified as hot or cold. Hot pressure washers are specially for industrial cleaning. They are ideal where some very tough cleaning is required. Hot pressure washers have burners inbuilt within them, which produce heat within.

There are hundreds of hot pressure washer models on the market. These have various PSI (pounds per square inch), which indicates water pressure, and GPM (gallons per minute) options ranging from 1000 PSI to 4000 PSI and 2 GPM to 11 GPM. They also vary on the basis of the voltage- 115, 208, 230, 460 or 575 volts and the phases- single or three-phase.
