Difference Between Power Washing and Pressure Washing
Pressure Washing and Power Washing are two different ways to clean surfaces. They do the same thing, but they go about it in very different ways. Both power washing and pressure washing can be used to remove dirt, mould, algae and other contaminants from a variety of building materials such as brick, vinyl siding and wood. But each is best for certain types of surfaces. For more details, visit the website.
The first big difference between power washing and pressure washing is how each method uses water to clean off those unwanted elements. With pressure washing you put water under a lot of pressure – usually with a pump – which forces the water out through a nozzle at high speed. It atomizes as it comes out creating a fine spray that’s directed onto whatever surface you’re cleaning.
With power washing, water is being pushed onto a surface under high pressure but it’s not getting atomized like with pressure washing. The result is that the water comes out of the machine in sheets rather than droplets and can clean large areas more quickly because of its weight and force.
Power washers work by pumping water from a garden hose into an open tank with a pump at one end and a spraying nozzle near the other end. The pump moves the water through the machine and out of the sprayer. A trigger allows you to control how much or how little of that pressurized water gets released which conveniently also helps regulate how strong it will be when it hits whatever you’re trying to clean.
For most power washing jobs, the nozzle is set with a fan spray pattern. That means it sprays all sides of whatever you’re cleaning. It’s able to do that because the way the water is being pushed out creates good coverage even at an angle. But if there are spots on your house or sidewalk where you need more concentrated pressure, you can switch to a pinpoint spray pattern by moving the nozzle closer in and then increasing how much-pressurized water gets released into that stream.
Smaller patterns have a less open surface area which increases their ability to put out more pressure over a specific spot compared to larger patterns with more surface area.
Pressure washing usually involves using some type of wand attached to a high-powered water pump that gets mounted on a truck, van or other vehicles. The wand is flexible so it can be bent in all directions which gives you better access to hard-to-reach spots. Plus, the weight of the water when forced through a smaller nozzle makes pressure washing more effective than power washing when it comes to removing mould and mildew from surfaces like brick walls and roofs.
Power washers usually have either gas or electric motors with their main parts consisting of a pump (for moving water), an engine (for powering the pump) and a hose (for connecting everything). They’re heavier than pressure washers but there are light-weight models available for users who want something they can easily carry around in one hand. Gas-powered machines are more powerful than electric ones but electric machines are typically cheaper.
Power washers can be used to clean many different outdoor surfaces or just about any indoor surface that gets dirty. The only restriction is that you need to use water with them so they can’t be used in areas where there’s no nearby source of potable water like a lake, stream or hydrant.
While power washing offers an easy way to get rid of mould and mildew, it’s not always the best option for cleaning surfaces because it takes off thin layers of material as well as dirt. That means your house could end up looking worn over time if you’re using this method to clean siding or exterior brick walls regularly.
