A pressure washer is a machine that uses a high-pressure stream of water to clean surfaces. The basic components of a pressure washer include a motor or engine, a water pump, and a high-pressure hose with a trigger gun.
When the motor or engine is started, it drives the water pump which draws water from a water source, such as a garden hose or a water tank. The water is then pressurized by the pump and forced through the high-pressure hose and out of the trigger gun at a very high pressure.
The pressure is usually measured in pounds per square inch (PSI), and the amount of water flow is measured in gallons per minute (GPM). The pressure and flow rate can be adjusted using the control knobs or nozzles on the trigger gun to suit the cleaning task.
The high-pressure water stream is very effective at removing dirt, grime, and other contaminants from surfaces such as concrete, brick, and siding. Some pressure washers also come with attachments such as rotating brushes or surface cleaners that help to further enhance the cleaning process.
It's important to note that pressure washers should be used with caution as the high-pressure water stream can be dangerous and cause damage to surfaces or injury to people. It's recommended to follow safety guidelines and manufacturer instructions when using a pressure washer.
