What is a good PSI for a pressure washer?

If you are a pressure washer buyer, at one point or time you might have asked yourself the right kind of PSI that is relevant for your use “What is a good PSI for a pressure washer?” This has always been a difficult question to many and answers will always differ because of many reasons.

 PSI (pounds per square inch) is the unit that is used to measure the pressure that is put out by a power washer. What is unique is that the PSI unit will always vary because of the surface or the aim you are intended to do your cleaning. You don’t have to get a more powerful pressure washer to clean salt and dirt or dust from your vehicle, but you will have to use a powerful machine when you are cleaning oil stains from the floor.

You also need to consider the gallons per minute (GPM). This is the measure of how much more water that is put out per minute by the machine. It also good to note that more water will equate to faster cleaning. You always have to learn and know how much pressure is required to clean different surfaces successfully. That is what will help you determine the size and also the kind of pressure washer that you will use successfully.

If you are never going to need a pressure washer with a PSI exceeding 2500, save your money and buy the 2600 PSI machine instead of going to use the 3000 or 4000 PSI machine. 

You don’t have to get to use the higher ones and pay for more while you will be cleaning your surfaces. But at the same time, it is good to know what is required so that you complete different tasks. at that juncture, then you might be in need of selecting powerful washer machines.

The pressure of water will provide you with the power to break up the stains and dirt that has settled in. but the availability of water and a better volume is what will ensure that filth and dirt is broken and disposed away. 

You have to know that the more water that passes through the nozzle in a minute, the faster you have to accomplish your cleaning. This essentially means that you have a greater GPM and it will ensure greater and faster cleaning. This is because more water will be available to lift and also carry away any dirt that they come across.

Now, we can do this in a practical manner or way. Let’s take a clump of dirt that has manifested itself on your sidewalk. You take a squirt gun and shoot at it while cleaning. It will be a good thing because it will just break it up but the unfortunate part is that the dirt will still be there. 

That will not have solved your problem. If you take a five-gallon bucket of water and pour it on the dirt, it will wash it away. Up to that point, you will realize that combining the pressure of the gun and the bigger volume of water will ensure that you easily wash your away dirt since you will have a better tool.

Pressure washer machines are one of the greatest tools in the world because they will just allow you to have a better cleaning tool.
