How To Tell If A Pressure Washer Is Good At Cleaning?

Pressure washers are fantastic tools.
These multi-purpose tools can save you a tonne of time and effort when it comes to accomplishing a variety of tasks around the house!
Pressure washers were once just used to clean the paving stones around your home, but they are now commonly used to clean walls, fence panels, conservatories, barns, cars, and much more!

A pressure washer is a machine that uses water pressure or force to remove dirt and debris from various hard surfaces.
But what makes a pressure washer so effective at cleaning and doing what it does?
What makes them so valuable for the extra money spent on soap and a strong brush?
Because, let’s face it, they’re absolutely worth the money!

The Mechanics of a Pressure Washer

Water is employed to some amount in practically all cleaning scenarios, and there’s a solid reason for it!
Water molecules have a small amount of electrical polarity, which causes them to adhere to surfaces (these things will then remain stuck to them when the water washes away).

If you then boost the pressure of this water to the same level as a pressure washer, you can’t go wrong!
The pressure washer’s water pump increases the pressure of the water to the point that it is forced out of the nozzle at such a fast speed that it hits the surface with great kinetic energy, knocking the dirt away.
To put it in perspective, the water jets are propelled out at pressures ranging from 1500 to 3000 psi (pounds per square inch), which is more than 100 times the pressure of the air around us!

Furthermore, many pressure washers now allow for the addition of a detergent attachment (or sometimes this can be added into the actual water tank itself).
Detergents are designed to break down grime and grease, causing the filth to adhere to water molecules even more, making it easier to wash away!

We know, it’s so easy, but it’s also so ingenious!

What Is the Process of Using a Pressure Washer?

A pressure washer is made up of several different pieces that work together to make it perform as effectively as it does!
It’s critical to comprehend each part’s function in order to properly comprehend how they function.

Water inlet – The water inlet is where the pressure washer gets its water from.
This is usually accomplished with a hose attached to the pressure washer (or a tank attached to the pressure washer if you don’t have access to an outdoor tap!).

The pump is powered by an electric motor (or, in certain cases, petrol-fueled motors for much larger, more commercial pressure washers) (which is arguably the most important part of the pressure washer).

Water pump – You can’t have a pressure washer without a water pump!
It’s difficult to comprehend how fast the water pump operates!
The pump whips the water into a frenzy, causing it to build up to dangerously high pressure!
Once the water tank is pressurised, it will pull one way to suck water into it, then push the other direction at high rates to drive the water out.
These water pumps typically pump 4 to 8 litres per minute (in regular household units)!
This is difficult to comprehend, yet it explains why pressure washers are so effective at cleaning!

High-pressure hose – The hose that emerges from the washer is strengthened with wire mesh and high-density polyethylene to withstand the pressure of the water that is being sprayed through it!
After that, it’s on to the nozzle!

Last but not least, Nozzle!
The water is shot via a small hole in the nozzle, increasing the pressure on the surface you’re trying to clean.
The small opening ensures that the water jet hits the surface in a tight, high-pressure stream, making it more effective in cleaning!
This will frequently feature adjustable settings that allow you to vary the way the water strikes the surface, as well as the ability to add a cleaning chemical to make a pressure washer even more effective!

The key to all of these elements functioning together is that they generate a tremendous amount of pressure, which forces tough dirt off whatever surface you’re working on.
However, because it is merely water and hits at such a high speed (as anyone who has ever been sprayed with a pressure washer knows! ), it will not destroy the actual hard surfaces that you are striking because they are so much stronger.

TOP TIP: Test the pressure washer on a less visible region before tackling the entire area!
When the surface you’re dealing with is already weak or broken (for example, grouting between flags), the pressure of the washer can be too much for it, causing even more damage!

Most Commonly Asked Questions

What is the best way to clean a pressure washer?

Because your pressure washer cleans so well, it’s easy to forget that it will need to be cleaned at some point!
Make sure the inlet filter is removed and cleaned to ensure there are no clogs.
Inspect and unclog the hose’s real nozzle as well (this can be done with a small pin or needle if you are careful not to stretch the hole as this will reduce the pressure).

What’s the difference between power and pressure washers?

Pressure washers and power washers are nearly identical, but there are a few major differences.
A pressure washer uses cold water at a specified pressure to remove filth (although it can function with water of any temperature), whereas power washers only use pressurised hot water.
