Pressure Washers Buyer’s Guide

How does pressure washer work?

In a pressure washer, a gas or electricity-driven motor powers the pump that accelerates the water supplied through a high pressure-rated hose to produce high pressure. At the end of the hose is a spray gun. When triggered, water mixes with air and comes out of the nozzle of this spray gun, the water stream varies in pressure, ranging from a very high concentrated stream of water that can scrape off the paint from a wall to a wider stream safer to remove dirt from surfaces.

Why do we need a pressure washer?

It is inevitable to deny the need for a pressure washer for cleaning large surfaces of all kinds that are very difficult and time-consuming to clean manually. It is also needed to get rid of tough stains like grease, oil, wax, and even rust. Since these are used for washing surfaces with large areas and tough stains, it is not a smart move to use them for regular cleaning purposes unless there are some seriously tough to remove stains because it is always going to take more time setting up a machine to clean the stain rather than cleaning it by hand.

How to Choose the Right One?

Pressure washers are among the essentials in your cleaning equipment’s panel and efficient against multiple kinds of stains and dirt. Since buying a pressure washer is such an investment, selecting the right one that suits your needs is very important. Here are a few tips to help you select better. There are a few major factors to consider while opting for a washer.

Power level

You don’t necessarily need a high-power model, just the one that suits the tasks you perform. The amount of pressure in a water stream is expressed in Pounds per Square Inch PSI, while the volume of water delivered by the pump is expressed in Gallons Per Minute GPM. It means the greater the PSI value higher the power, while the greater the GPM faster the cleaning.

In general, there is a range of water pressure for every task you do, and if you exceed that range, the pressure becomes higher enough to harm your sensitive or delicate material. For regular cleaning tasks like cleaning a vehicle, 1300 to 2400 psi is enough. Washing off tougher stains like that of concrete or steel will need a pressure of about 3000 PSI with 4 GPM, while stripping of vinyl or paint from a surface might require 4000 psi. However, you won’t be needing this much PSI value if the model is to be used as a residential pressure washer.

Electric v/s gas

If the washable item is in the vicinity of a power outlet, then the electric washer will do the trick. These generally have about 1500 PSI and a GPM of approximately 1.5. These are comparatively cheaper and less noisy. Whereas gas-driven pressure washers are used for medium to heavy-duty tasks such as washing tough stains like concrete or sidings of a house.

Coldwater v/s shot water

Cold water pressure washers are ideal for removing dirt, mud, and sand and are comparatively cheaper yet efficient. Whereas hot water pressures are preferable for eliminating oil and grease since hot water better cuts through these to provide cleaner surfaces.

Consumer v/s professional?

Consumer models are meant to be used occasionally, and these don’t work well if used daily or more often. Professional models are designed for regular use and built accordingly to support the function. These have features like in-built detergent tanks, pro-style spray guns, and wands that allow easy gripping by hand and making daily tasks easier. Some of these also include multiple quick-change nozzles.

Nozzle selection

The size of the nozzle defines the angle of a water stream. A smaller opening means more concentrated spray. Many pressure washers come with multiple nozzle tips that are color-coded according to spray angle.

Red:0-degree spray – which means water is highly concentrated sensitive surfaces are prone to damage.

Yellow: 15-degree spray – comparatively less concentrated stream and is suitable for mild washing tasks.

Green: 25 degrees – the water stream is wider and is suitable for household cleaning tasks.

Black: 65 degree – it is likely to be used for spray detergent or soap on a surface before washing it.

What features to consider while buying a pressure washer?

There are some important features to consider while buying a pressure washer, and you never know what important feature you might be missing while purchasing your perfect pressure washer. Following are some considerable features that help you decide the definition of a pressure washer that suits your requirements.

Water pressure

You don’t necessarily need a high PSI model, just the one that suits the tasks you perform. The amount of pressure in a water stream is expressed in Pounds per Square Inch PSI, while the volume of water delivered by the pump is expressed in Gallons Per Minute GPM. It means the greater the PSI value higher the power, while the greater the GPM faster the cleaning.

In general, there is a range of water pressure for every task you do, and if you exceed that range, the pressure becomes higher enough to harm your sensitive or delicate material. For regular cleaning tasks like cleaning a vehicle, 1300 to 2400 psi is enough. Washing off tougher stains like that of concrete or steel will need a pressure of about 3000 PSI with 4 GPM, while stripping of vinyl or paint from a surface might require 4000 psi. However, you won’t be needing this much PSI value if the model is to be used as a residential pressure washer

Power Supply

Be it electricity or gasoline driven, the only thing that matters is its compatibility with the task you are performing. If the washable item is in the vicinity of a power outlet, then the electric washer will do the trick. These generally have about 1500 PSI and a GPM of approximately 1.5. These are comparatively cheaper and less noisy. Whereas gas-driven pressure washers are used for medium to heavy-duty tasks such as washing tough stains like concrete or sidings of a house.

Nozzle Types

With your pressure washer, you’ll get a set of nozzles to be used according to the varying requirements of your task. The size of the nozzle defines the angle of the water stream. A smaller opening means more concentrated spray. Many pressure washers come with multiple nozzle tips that are color-coded according to spray angleThesese are generally available as 0-degree, 15-degree, 25-degree, 40-degree, 60-degree, and soap nozzle for application of detergent on the washable surface. The 0-degree nozzle has the most concentrated water stream meaning higher pressure that can even damage sensitive surfaces. In contrast, as the degrees increase in value, the stream concentration decreases towards a wider stream.

Mobility

It is one of the key factors to be considered since easy to maneuver machine allows to perform the task easily. A heavy machine that is difficult to carry and move around will cause difficulty in washing. Many models come with heavy-duty wheels, adjustable and foldable handles that make it convenient to move the machine around while working.

Budget

No one wants to waste their hard-earned money on an unsuitable product, especially machinery. In general, gas-powered washers are more expensive than electric ones. So, if you’re going to use the model for residential cleaning electric-powered model comes in handy, while for heavy-duty tasks, gas-driven models are more suitable.


FAQ

What is meant by PSI and GPM?

When considering the performance of a pressure washer, these two terms are used to define its efficiency. PSI stands for Pounds per Square Inch, and it is the amount of pressure in a water stream. GPM stands for Gallons Per Minute, and it is the volume of water delivered in one minute. It means the greater the PSI value higher the power, while the greater the GPM faster the cleaning. You don’t always necessarily need a high PSI or GPM model, just the one that suits the tasks you perform.

What PSI should my pressure washer be?

Be it electricity or gasoline driven, the only thing that matters is its compatibility with the task you are performing. If the washable item is in the power outlet’s vicinity, then the electric washer will do the trick. Whereas gas-driven pressure washers are used for medium to heavy-duty tasks such as washing tough stains like concrete or sidings of a house. In general, there is a range of water pressure for every task you do, and if you exceed that range, the pressure becomes higher enough to harm your sensitive or delicate material. For regular household cleaning tasks pressure washer having 1300 to 2400 PSI is enough.

How much water does a pressure washer uses?

Though pressure washers rely on large volumes of water to clean surfaces, a model that uses less water is considered more efficient. As a rule of thumb, the higher the pressure, the more efficient the machine is, and less water is used. An average washer is about 8 GPM, and a pressure washer of say, 5 GMP will be more efficient since using less water volume to clean the surface in a minute at high pressure of about 10 -50 PSI.

What is meant by CARB Compliant?

Since pressure washers are run by fuel, they emit exhaust and have a negative impact on the environment. You will find generators that have a tag of CARB-compliant on them. CARB stands for California Air Resources Board, and this board has set a criterion by which the equipment must abide to reduce the harm imposed by pollutants on the environment. So, when a pressure washer or any device is CARB compliant, it means that it meets the standards of this board.

What’s the difference between gas and electric models?

As the name suggests, one is fueled by gas and the other by electric power. Electric pressure washers generally have about 1500 PSI and a GPM of approximately 1.5. These are comparatively cheaper and less noisy, and suitable for household cleaning tasks and less frequent uses. If the washable item is in a power outlet’s vicinity, then an electric washer is preferred to be used. Whereas gas-driven pressure washers are used for medium to heavy-duty tasks such as washing tough stains like concrete or sidings of a house.


Summary/Conclusion

Few people might disregard the need for a pressure washer considering it unimportant, or it could harm their products through high pressure. But in a broader perspective, it is inevitable to deny the need for a pressure washer for cleaning large surfaces of all kinds that are very difficult and time-consuming to clean manually. It is also needed to get rid of tough stains like grease, oil, wax, and even rust. But some other less known benefits are that regular cleaning of surfaces around us leads to lesser environmental and health issues as the washer eliminates harmful pollutants from our surroundings. Thus, even if not much considered but the benefits an efficient pressure washer brings along must be acknowledged.
