A pressure washer is simply a water pump driven by an electric motor. The washer gets its water from a faucet, while the pump increases the pressure of the water and then squirts it out a hose at fast speed through a trigger pistol.

The following are the common parts of a pressure washer:

Water Inlet

The pressure washer is connected to the main water supply through a hose. A filter in the inlet prevents dirt and debris from entering the washer and clogging the system. Little bits of grit is the last thing you want inside your washer because they may come blasting out of the other end at top speed.

Water Pump

This is similar to a hand-operated ground-water pump. It is powered by an electric motor or gas engine rather than your hand. Whenever the engine pulls the pump on one side, water is sucked in from the faucet.

When the engine pushes the pump to another side, water is sprayed out in a high-pressure jet. Pumps are built to handle 4–8 liters of water per minute.

High-Pressure Hose

The tube extends from the washer to whichever cleaning attachment you have chosen. A regular piece of tubing would not be able to withstand the enormous pressure of the water pouring through the nozzle. The high-pressure hose comprises two or more layers of high-density polyethylene and is reinforced with wire mesh.

Cleaning Attachment

It usually depends on what you want to be cleaned, pressure washers can use a basic trigger gun, a spinning wand spray, or a revolving brush to scrub your drive or any inconspicuous area. The water pressure flowing through powered attachments propels them.
