What Is a Pressure Washer?
A pressure washer is a powerful cleaning tool that uses high-pressure water spray to remove dirt, grime, and other unwanted materials from surfaces. It typically consists of a motor or engine that drives a water pump, a high-pressure hose, and a wand or spray gun with various nozzles that control the spray pattern and pressure.
Pressure washers are commonly used for outdoor cleaning tasks such as washing cars, decks, patios, driveways, and sidewalks. They can also be used for industrial cleaning applications, such as removing grease and oil from machinery or cleaning industrial equipment and buildings.
How Does It Work?
Pressure washers work by using a motor or engine to drive a water pump, which pressurizes water from a connected water source and forces it through a high-pressure hose and wand or spray gun.
The water pump typically has an inlet connected to a hose that draws in water from a source such as a faucet or a reservoir. The pump then pressurizes the water and sends it through a high-pressure hose connected to the spray gun.
The spray gun has a trigger controlling the water flow and a nozzle determining the spray pattern and pressure. Different nozzles can be attached to the spray gun to adjust the pressure and spray pattern for different cleaning tasks.
When the trigger on the spray gun is pulled, the high-pressure water spray is directed at the surface to be cleaned. The pressure and flow of the water effectively remove dirt, grime, and other unwanted materials from the surface.
Some pressure washers have detergent tanks that allow soap or other cleaning agents to be added to the water stream for even more effective cleaning.
Types of Pressure Washers
There are four main pressure washers: electric, cordless, gas, and commercial. Each type has its advantages and disadvantages, and choosing the right one depends on your specific needs.
Here is a summary table of the four:

A Complete Buying Pressure Washer Guide
PSI and GPM
These two numbers are very crucial to decide what pressure washer you need.
PSI measures the pressure the water is delivered at and determines how much force the washer can generate. A higher PSI means the washer can produce more force and is better suited for tougher cleaning tasks, such as removing stubborn stains or dirt. However, it’s important to note that a higher PSI can also damage more delicate surfaces, so choosing the appropriate PSI for the task at hand is important.
GPM measures the amount of water that the washer can deliver in one minute. A higher GPM means more water is delivered and can help wash away dirt and debris more quickly. A lower GPM may be sufficient for smaller cleaning tasks, but a higher GPM is recommended for larger areas to ensure a thorough cleaning.
When choosing a pressure washer, consider the suggested PSI and GPM ranges for different cleaning tasks:
- Light-duty cleaning: PSI range of 1300-1900, GPM range of 1.2-1.5. Suitable for cleaning vehicles, outdoor furniture, and other small items.

Frequently Asked Questions
#1 What’s more important, PSI or GPM?
PSI measures the pressure the water is delivered, while GPM measures the amount of water the washer can deliver in one minute.
Generally, a higher PSI means that the pressure washer can generate more force and is better suited for tougher cleaning tasks, such as removing stubborn stains or dirt. However, a higher PSI also typically means a lower GPM, which can result in slower cleaning times.
Conversely, a higher GPM means that the pressure washer can deliver more water, which can help wash away dirt and debris more quickly. However, a higher GPM typically means a lower PSI, making it less effective for tougher cleaning tasks.
Therefore, the ideal combination of PSI and GPM will depend on the specific cleaning task. For example, a lower PSI with a higher GPM may be suitable for washing a large surface area, while a higher PSI with a lower GPM may be more effective for removing stubborn dirt or stains.
#2 What is the ideal pressure washer for home use?
For most homeowners, an electric pressure washer with a PSI of 1500-2000 and a GPM of 1.4-1.6 is sufficient for most cleaning tasks around the house, such as washing cars, cleaning outdoor furniture, and removing dirt and grime from driveways and sidewalks.
Gaspowered pressure washers are also a good option for homeowners who need more power for tougher cleaning tasks or have larger outdoor areas to clean. A gas pressure washer with a PSI of 2500-3100 and a GPM of 2.5-3.2 is suitable for most home cleaning tasks and can also handle tougher jobs such as cleaning concrete surfaces and removing paint.
#3 Can I use hot water with a pressure washer?
It depends on the type of pressure washer you have. Some pressure washers are designed to handle hot water, while others are not. Using hot water with a pressure washer can effectively remove dirt and grime from surfaces, especially greasy or oily stains.
If you have a pressure washer that is designed for hot water use, it will usually be labeled as a hot water pressure washer or have a specific temperature range listed in the owner’s manual. Hot water pressure washers typically have a heating element that heats the water as it passes through the pump, allowing for more effective cleaning.
However, if you have a pressure washer not designed for hot water use, it can cause damage to the pump and other components of the machine. In addition, using hot water with a pressure washer that is not designed for it can also create a safety hazard, as the hot water can cause the machine to overheat or malfunction.
#4 How often should I change the oil in my gas pressure washer?
The frequency of oil changes in a gas pressure washer depends on the manufacturer’s recommendation, which can vary based on the model and usage. Generally, it is recommended to change the oil in a gas pressure washer after every 50-100 hours of use or at least once a year, whichever comes first.
#5 What type of detergent should I use with my pressure washer?
The type of detergent you should use with your pressure washer depends on the surface you are cleaning and the type of pressure washer you have. Many different types of detergents are available, each formulated for specific cleaning tasks.
A mild detergent or soap designed for pressure washers can be used for general cleaning tasks, such as cleaning driveways, sidewalks, and outdoor furniture. These detergents are usually biodegradable and safe for use on most surfaces.
Or, for cleaning cars and boats, you can use a car wash soap or a specially formulated cleaner for vehicles. These detergents remove dirt, grime, and other contaminants without damaging the paint or finish.
#6 Is it safe to use a pressure washer on my car?
Yes, it is safe to use a pressure washer on your car as long as you follow some important guidelines:
- Use a low-pressure nozzle: A pressure washer can damage your car’s paint and finish if you use a high-pressure nozzle. Always use a low-pressure nozzle, such as a fan or soap nozzle, to avoid causing any damage.
- Use the right detergent: Choose a detergent that is specifically formulated for use with cars. Car wash soaps are designed to remove dirt and grime without damaging the paint or finish.
- Keep a safe distance: Hold the pressure washer wand at least 2 feet away from the car to avoid causing any damage.
- Avoid sensitive areas: Be careful when using a pressure washer around sensitive areas, such as door handles, mirrors, and windows. These areas can be easily damaged by high-pressure water.
- Rinse thoroughly: After washing your car with a pressure washer and detergent, be sure to rinse it thoroughly with clean water to remove any soap residue.

I love to share my tips & tricks to all car lovers, so that’s why I’m here at Automotive Gearz publishing my content, sharing my passion. Also, I’ve been giving my recommendations on which products are the best to have on the market. I always thought it was hard to pick the right part, so hopefully I can make that a bit easier for you.
Hope you enjoy your time on my little blog!
