Pressure washers operate on a simple conversion of water flow into high-pressure jets. This makes it capable of dislodging dirt, grime, and debris from various surfaces. Pressure washers rely on a combination of water flow, pressure, and specialized nozzles to achieve optimal cleaning results. 

The working mechanism of a pressure washer involves the pump pressurizing water from the inlet, which is then delivered through the high-pressure hose to the spray wand or nozzle. The high-pressure water jets emitted from the nozzle strike the surface with force, dislodging dirt, grime, and other contaminants. The combination of high pressure and water flow facilitates efficient cleaning, making pressure washers indispensable tools for a wide range of cleaning tasks. The basic components of a pressure washer include:

• Water Inlet: Pressure washers are connected to a water source, typically a garden hose, which supplies water to the machine.
• Pump: The heart of the pressure washer, the pump, is responsible for pressurizing the water. It draws water from the inlet and increases its pressure to the desired level based on the settings chosen by the user.
• High-Pressure Hose: The pressurized water from the pump is conveyed through a high-pressure Hose to the spray wand or nozzle.
• Spray Wand/Nozzle: The spray wand or nozzle serves as the point of delivery for the pressurized water onto the surface being cleaned.  
• Trigger Gun: The trigger gun controls the flow of pressurized water from the nozzle. By pulling the trigger, the user activates the flow of water, and releasing it halts the flow.
• Engine or Motor: Pressure washers may be powered by electric motors or gas engines, providing the necessary energy to drive the pump and generate high-pressure water jets.
