Buyers Guide

Clean your deck, car, or siding with the wrong pressure intensity and you might strip off the paint –– or worse –– physically damage the surface. Many factors, not just the pressure washer’s cleaning power, should play into your decision when buying the perfect pressure washer for you and your home. 

Here are some key pressure washer terms and their definitions:

PSI and GPM

When shopping around for your pressure washer, PSI and GPM are two factors you’re sure to see the most. Here is what they mean: 

What is PSI?

PSI is short for pounds per square inch. PSI measures the water pressure. The PSI helps you determine how powerful the stream of water will be. 

If a pressure washer has a 4000 PSI, that means the water stream is hitting the dirty surface with 4000 pounds of pressure per square inch. 

What is GPM?

GPM is short for gallons per minute. It measures how much water is moving through the pressure washer. If a pressure washer has 2 GPM, that means it has a water flow of 2 gallons per minute. 

The GPM helps you determine how fast the pressure washer will clean the surface and wash away debris. If two pressure washers have the same PSI, the one with the higher GPM will clean the debris faster. A lower GPM means it will take longer to clean the surface. 

How to calculate cleaning power:

To calculate a pressure washer’s total cleaning power, multiply the tool’s PSI by its GPM (PSI x GPM). Calculating the cleaning power will help you compare the performance of different pressure washers. 

PSI levels

A big mistake you can make when operating your new pressure washer is using it on a surface that can’t handle the cleaning power. A high PSI pressure washer may significantly damage the surface you are trying to clean. 

Always review the owner’s manual or item specification to see what tasks the pressure washer is designed to perform. 

Switching out the nozzles for the appropriate spray pattern and angle can help reduce the intensity of your pressure washer, making it safer to use for lighter jobs and sensitive surfaces, like cars or outdoor furniture. 

The Pressure Washer Manufacturers’ Association breaks down appropriate PSI levels into three categories:

Best for light-duty work

Definition of light-duty work:

  • Up to 1900 PSI
  • Between 1.1 GPM and 1.4 GPM

Examples of light-duty work:

  • Patio furniture
  • Grills
  • Cars
  • Walkways
  • Boats
  • Windows
  • Dirt bikes

Best for medium-duty work

Definition of medium-duty work:

  • Between 1900 PSI and 2800 PSI
  • Between 1.8 GPM and 2.5 GPM

Examples of medium-duty work:

  • Driveways
  • Sidewalks
  • Siding
  • Paint prep

Best for heavy-duty work

Definition of heavy-duty work:

  • 2800 PSI or more
  • 2.5 GPM or more

Examples of heavy-duty work:

  • Decks
  • Patios
  • Oil stains
  • To remove rust, paint, or graffiti. 

Consider what your cleaning needs are. If you only need to wash your cars, windows, or boats, you may want to stick with a pressure washer designed for small jobs. Otherwise, you’ll pay more for higher pressure you really don’t need. 

Power source

A pressure washer can have one of three power sources: gas, electric, or battery. Users will find that each power source will meet their needs in different ways.

Gas-powered: 

Pros: 

✓ Most gas-powered pressure washers have significantly better cleaning power than corded electric and battery-powered pressure washers. 
✓ Ideal for commercial work or heavy-duty applications. 
✓ Gas-powered pressure washers ensure mobility, as the machine doesn’t need to be plugged into an outlet and isn’t restricted by a power cord. 

Cons: 

✗ Gas pressure washers are often more expensive, noisier, and heavier than corded electric or battery models. 
✗ Because they run on gasoline, these machines emit exhaust fumes harmful to you, the user, and the environment. 

Corded electric:

Pros: 

✓ Corded electric pressure washers are a great choice for light-duty or medium-duty home projects. 
✓ They are much better for the environment than gas-powered pressure washers, quieter, lighter, and far less expensive. 

Cons: 

✗ Corded electric pressure washers tend to have lower cleaning power than gas-powered pressure washers.
✗ Power cord restricts the user’s mobility. 

Battery: 

Pros: 

✓ Battery-powered pressure washers allow the user to work anywhere –– no outdoor outlets needed. 
✓ Better for the environment than gas-powered pressure washers.

Cons: 

✗ Battery-powered pressure washers aren’t as powerful as gas pressure washers.
✗ Cordless tools have a limited run time. Once the battery runs out of juice, it will need recharging. 

Pump

Your gas-powered pressure washer will have either an axial or triplex pump. Let’s look at the difference between the two: 

Axial

Axial pumps are best for homeowners taking care of small jobs. Your pressure washer’s axial pump will require little maintenance from you while still getting the job done. 

Triplex

Triplex pumps are best for frequent commercial or heavy-duty use. Despite the added maintenance and higher price tag, a triplex pump ensures the pressure washer has a longer lifespan and greater efficiency. 

Amperage

Amperage is the strength of an electric current in amperes, written amps for short. Amps help measure the maximum time a motor can run continuously without exceeding its temperature limits. If your corded-electric pressure washer begins to overheat, this isn’t so great for the machine.  

Hose length

Hose length will vary depending on the pressure washer you buy. 

A long hose adds mobility. When operating a heavy gas pressure washer, a long hose helps you avoid lugging a 130-pound machine as you work. When using a corded-electric model, you’ll likely find a long hose gives you an extended reach. 

Wheel size

The bigger a pressure washer’s wheels, the easier it is to maneuver the machine over bumpy terrain. 

Water source

Plan where you’ll get all the needed water from. If your pressure washer operates at 4 GPM, that means you’ll need a water source that can consistently provide four gallons of water per minute. And remember: You’ll need a garden hose that connects to the water source.

A water well is typically not a good source, as it may not provide enough water. A city water supply may be more reliable. 

Don’t have a water source? Don’t sweat. Buy a water tank to hook up to your pressure washer. Some pressure washers even come with a built-in water reservoir you can refill in the bathroom sink. 

Detergent 

Some pressure washers are compatible with detergents or other cleaning chemicals. Always check the instruction manual before using your power washer with a cleaning aid. 

Nozzles

A pressure washer’s various nozzles control the angle and focused intensity of the water stream. Depending on the task, you may want to change the nozzle to either lower or increase the stream’s intensity. If you don’t use the correct nozzle for the job, the severe pressure may be too much for the surface to handle. 

Your pressure washer’s wand ought to come with color-coded interchangeable nozzles or an all-in-one adjustable nozzle. 

Noise 

Your pressure washer is going to emit a lot of noise. Before swiping the credit card, ensure your pressure washer’s decibel rating (dBA) is appropriate for local laws. Many counties and cities have ordinances in place to limit noise pollution. 

Remember, gas-powered pressure washers are often noisier than corded electric and battery models.

Potential risks

A pressure washer is not a toy. It can cause serious injury if not operated with care. A pressure washer with a high enough PSI can slice through the skin or send a person to the emergency room. 

Never point a pressure washer at another person. 

FAQs About Pressure Washers

1. What is the difference between a power washer and a pressure washer?


Power washers and pressure washers have one key difference. Both use pressurized water to remove grime from surfaces. But only a power washer heats the water. 

Heated water can damage the surface you are cleaning. Never assume that you can use a power washer on the same surface you used a pressure washer. 

2. How do I use a pressure washer safely?


It’s essential to operate a pressure washer safely and correctly. Otherwise, you risk causing serious injury to yourself, others, or the surface you are cleaning. 

Here is a checklist to safely use a pressure washer:

  • Avoid setting the water angle to 0 degrees. This angle channels the stream’s entire intensity into one single point, making it more dangerous to use. 
  • Use the appropriate nozzle for the surface you are cleaning.
  • Read and follow the instruction manual. 
  • Always wear safety goggles, boots, gloves, long pants, and hearing protection.
  • Be aware of your surroundings as you use your pressure washer.
  • Check electrical cords before use to avoid shock.
  • Check the user manual before plugging an electric pressure washer into an extension cord. 
  • Never aim the pressure washer wand at another person. 
  • Never clean a surface with a PSI that is too high.
  • Never operate a gas-powered pressure washer in an enclosed space. 
  • Never operate a pressure washer while on a ladder. 

When to Call a Professional

Worried about damaging your driveway, siding, or walkway? Concerned about pressure washer safety? You may feel more at ease with a professional on the job. Call a pressure washing professional near you to take the worry off your hands. 

After all, there’s no need to work under pressure. Leave that to the professionals.
