Everything You Need to Know About Pressure Washers

Pressure washers can make any type of cleaning job easier. However, there’s more to them than people think. In this segment, we’ll highlight virtually everything there is to know about pressure washers!

Understanding the basics

Before we get into the heart of the matter, we have to address the basics first.

When discussing power washers, there are two main things that serve as a differential. If you have your priorities sorted when it comes to these two factors, then you’re in for a good ride.

Motor type

The first thing that you have to learn about is the type of motor employed.

The most common types of electrical motors are electricity based. As with similar appliances, this motor needs to be connected to a power outlet.

The other type of motor that you have to know about is a gas motor. Gas based pressure washers are more oriented towards outdoor use. This is because they are noisier than usual and more heavily built.

Power rating

Power rating refers to the general strength of the power washer.

Measured in units of pound per square inch, or PSI, power rating indicates how strong a particular pressure washer is.

Generally speaking, the higher the power rating, the higher the velocity of the water jet will be. 

Choosing the right model

When setting out to get the right model for yourself, you have to be well-informed of all the options in front of you. 

The general purpose of this sub-segment is to present you with everything you need to know before setting out. Technically speaking, there are three categories of pressure washers that you can choose from. Without further ado, here are your options.

Electrical motor (1300-1900PSI)

Electrical motor based pressure washers with a power rating below 2000PSI are optimal for cleaning jobs for outdoor furniture, car washing, plastic play sets, grills, small decks and patios.

When choosing this type, there are a handful of features that you should definitely keep your eyes out for.

For starters, the model should be compact and lightweight. To prevent redundant trips back and forth, we’d also suggest onboard storage for both water and the detergent. Other than that, there are other essentials that are already part of the package.

Gas Motor (2000-3100PSI)

Gas motor based models are more versatile and can be used for a variety of purposes. These include cleaning jobs related to decks, vehicles, patios, fences, siding, and boats. They are also good for cleaning driveways.

The general criteria that you should look for is that the exterior should be solid made and is durable. This is to prevent any sort of washer operation damage on any sort of impact, or due to operation in extreme temperatures.

We won’t recommend that you use models like these indoors. This is because gas based models are prone to producing more noise than usual, which can often get irritating if done for longer periods of time.

Gas motor (3200-4200PSI)

Gas motors with a power rating exceeding 3000PSI are more geared towards professional and heavy-duty operation. 

These pressure washers are optimal for jobs concerning graffiti removal, fleet maintenance, paint stripping and surface preparation, graffiti removal, and construction-site work.

As mentioned above, make sure that you look for something that is portable and easy to maneuver around with. This will help you immensely in moving from place to place.

Another thing to watch out for is the noise. These models might get a little noisy, which is why it’s best to be prepared for what’s to come.

Making the most of it

Now that you’ve understood the essence of pressure washers, we’ll dedicate this sub-segment to subtle and random things that might help you out.

Note that you might already be aware of these things, in which case that’s good for you. However, we feel the importance to highlight them all over again so that those of us who aren’t that well-versed with pressure washers can make the most of this as well.

Nozzle adjustments

Nozzle adjustment is where you put money to good use. 

Generally speaking, the bulk of the models out there adhere to a particular rule that makes them interchangeable.

Pressure washer nozzles are differentiated on the basis of color. Due to their color coded appearance, you can easily tell what amount of force and narrowness the nozzle can handle.

The colors are white, green, yellow, and red, and adhere to temperatures around 40, 25, 15, and 0 degrees, respectively.

Note that all of these nozzles are well-suited for different jobs. Hence, don’t be afraid to experiment a little. The best way to do that is mentioned below!

Spraying tips

When trying out new nozzles, or trying to find out what nozzle might work best for you, we would highly suggest that you first try out the particular nozzle on a hard and solid surface. This will give you a general bearing of that nozzle’s strength.

Once you’ve established that, you can move onto more hands-on techniques.

For starters, it is highly advised that when dealing with vertical surfaces, start from the bottom up. When rinsing, start from the top. This will help in better cleaning and help you save water as well.

Another good thing to remember is to adhere to the lowest-nozzle rule. If you feel that a particular nozzle can get the job done with ease, don’t use different nozzles. Since water is already pressurized, there is a decent chance that the flow will cut the surface you’re cleaning.

Additionally, it’s a good idea to hold the washer’s nozzle at an angle a little above the surface. 

This will allow for even distribution and also prevent any sort of surface damage.

To make the job even safer, make sure that you move the nozzle from time to time. Don’t stay stationary at one position because that might lead to surface damage or breakdown.


Learning is a life-long process. However, we feel that all that’s mentioned above is the bulk of what’s there to know about pressure washers. If you have any more questions or queries, leave the comment below.
