How Does A Pressure Washer Work? Here’s Everything You Need To Know

Have you recently watched any of the intense cleaning or pressure washing videos online? Even if you haven’t, pressure washing can amaze any one of us. That’s because of its tremendous power to cut down the grime, grease, and dirt from tough surfaces. If done right, the surfaces appear to be restored to their new condition.  A lot of our customers inquire about how does a pressure washer work. Many of them intend to buy one for themselves, others are just curious souls. Being one of the most reliable pressure washing companies, we tend to answer your queries in the best way possible. Here is everything you need to know about the working of a pressure washer.

Key Principle Of Pressure Washer

Well, a pressure washer is less complicated than it sounds because all it uses is a jet of high pressured water. The water can be hot or cold and is generally mixed with detergent. When the water is pumped through a very thin nozzle, it breaks even the toughest of stains. Let’s have a look at the chemistry of water and detergent to understand the working of a pressure washer in a better way. Water is considered a universal solvent owing to its polar nature. Water molecules tend to make bonds with other partially charged molecules. Detergents help dislodge the grime and debris so that water can easily flush it away. Now add up the chemical power of a detergent and water with a pressure of 1500–3000 pounds per square inch and you can easily imagine why these super-powerful machines can blast things clean.

Components Of A Pressure Washer

Now you have some information about the key principle but when you are operating a power washer, you must know its components. Here is a brief description.

Gas Engine Or Electric Motor

The heart of every pressure washer is its fueled motor, which mainly drives the pump system. The ones generally used by homeowners are powered by electricity whereas the professional heavy-duty pressure washers are powered by a gas engine. They convert electrical or chemical energy to mechanical energy.

Water Pump

The water pump is driven at a high speed to suck water from the water inlet faucet and push it on the other way with a tremendous force. These water pumps are designed to handle about 4-8 liters of water per minute and squirt it out with high pressure. 

Water Inlet

As the name indicates, the water inlet connects the pressure washer to the main water supply. You will almost always find a small filter in the water inlet to prevent small particles from entering the water pump.

Water Outlet/ Nozzle/ Cleaning Attachment

The water outlet is attached to the power washer through a hose. At the other end of the hose is a cleaning attachment. They are varying forms of extension wands, rotating brushed and trigger guns to get the different surfaces sparkling clean! We hope this guide has been helpful for you.
