Which is The Best PSI for Pressure Washer

Last update: 2021-09-17

They say the best pressure washers are those that have the right pressure settings. If you don’t know the PSI rating of your tool it’s hard to say if it can cut through the types of hard stains you want to wash.

This is why we recommend choosing a pressure washer based on PSI ratings. The higher the pressure rating the more powerful and effective it will be.

What is the Best PSI for a Pressure Washer?

Before we get down to the detailed reviews of our top 13 pressure washers, let’s first clear out some basic definitions and concepts. Knowing about them will help you make a better purchase. More so, you can see through all the glittery marketing copy with lofty numbers that some manufacturers and retailers peddle online.

What is PSI?

Pounds per square inch (PSI) is the unit with which water pressure is measured. In other words, it is a measure of the force with which water is guzzled out of a hose, faucet, or nozzle. A typical garden hose has a PSI of between 40 and 60 vs an electric pressure washer that can amplify it up to 60x.

The higher the PSI the faster the cleaning process.

What is GPM?

Gallons per minute (GPM) is a measure of the amount of water being guzzled out. If PSI denotes the force, GPM denotes the volume. As you can guess, a higher GPM means more water is splashed onto the surface, giving you more cleaning power. GPM in cold pressure washers usually falls in the range of 1 and 5.

What are Cleaning Units (CU)?

Cleaning Units (CU) are a product of PSI and GPM. In the pressure washer industry, it’s a figure used to showcase the “cleaning power” of a tool. For example, if the PSI and GPM of a pressure washer are 2,000 and 2 respectively, the CU will be 4,000.

We don’t recommend measuring a washer’s worth by CU numbers. Instead, focus on pressure, GPM, and other metrics individually.

PSI versus GPM

Both PSI and GPM denote two different things. Therefore, they are both equally important.

PSI is a figure influenced by the motor and pump being used. On the other hand, GPM depends on the motor, pump, and the cross-section of the hose and nozzle. However, it can be said that they are interrelated. If you find a pressure washer with a decent PSI, it will naturally have a decent GPM rating.

This is why we recommend balancing them out. But, if you still had to choose between the two, focus on PSI as that will tell you how strong the motor and pump are.

How Do You Choose the Best PSI for Your Pressure Washer?

Which is The Best PSI for Pressure Washer

Choosing a pressure washer with the ideal PSI for your needs comes down to the following parameters. Check your pick against these points to make a wise purchase.

  • Type of use – homeowner vs professional (commercial use)
  • Type of operation – gas-powered vs electric
  • Type of water – cold vs hot pressure washer

As you can guess, commercial use will require more power to cut through harder stains (e.g.: industrial washing). Such heavy use will also demand a gas-powered pressure washer that can provide higher PSI (up to 5,000). Such high-powered tools are not ideal for home use as they require more care and precautions. In comparison, electric washers have lower PSI.

What PSI Pressure Washer Do I Need?

Based on your cleaning requirements, you can go with any of these three ranges:

  • Up to 2,000 PSI – Light-duty tasks such as washing dirt off patio, deck, walls
  • 2,000 to 3,200 PSI – Medium-duty tasks such as washing the grime off car tires, mildew off walls
  • 3,200 to 5,000 PSI – Heavy-duty tasks such as washing oily surfaces, grime, garage grunge

In America, the best pressure washer PSI for cleaning equipment is between 2,000 and 3,000. For cars, it can be slightly lower as there’s always the risk of chafing the paint off the surface.

Most professional pressure washer manufacturers provide a sample set of eligible tasks in their user manual. We recommend going through it once.

Best Pressure Washers by PSI Review

Now that we have a fair idea of the concepts, let’s dive deep into the top pressure washer models currently ruling the US market. For your convenience, we have categorized them by PSI.

#1 - Best 1450 PSI Pressure Washer: Sun Joe SPX1000

Snow Joe, the parent brand of Sun Joe, started as a snowblower manufacturer in 2004. Since then, it has diversified into pressure washers with this model here being one of its bestsellers.

Which is The Best PSI for Pressure WasherBest 1450 PSI Pressure Washer: Sun Joe SPX1000

Pros
  • Total Stop System (TSS) shuts off the pump automatically when the trigger is not pressed
  • Lightweight and compact tool design
  • Adjustable spray wand
Cons
  • Spray button needs to be bought separately

Pressure Washer Review

We love the compact design of this best light-duty pressure washer that ejects a decent amount of water at a maximum pressure of 1,450 PSI.

You can carry it anywhere as long as there is a power outlet nearby. It can cut through most types of dirt on surfaces such as concrete, deck, windows, siding, and driveway. The TTS system that shuts off the pump when the trigger is not pressed will save power and extend the lifespan.

#2 - Best 1500 PSI Pressure Washer: WORX WG601

Worx is that friendly neighborhood brand but based out of China. It focuses on simple tools that make the task at hand a lot easier, as opposed to advanced machines that sometimes make it harder. This 1,500 PSI pressure washer is a fair example of its tech marvel.

Which is The Best PSI for Pressure WasherBest 1500 PSI Pressure Washer: WORX WG601

Pros
  • Total Stop System (TSS) for power conservation
  • Turbo nozzle for 360-degree spray
  • Compact design with easy carry handle
  • On-board storage
Cons
  • Weak attachments (water hose plug)

Pressure Washer Review

Compared to the Sun Joe machine, this one is a tad lighter and compact. While that may be because of the cheaper material used to build it and its plugs, it does pack a lot of power.

With a max PSI of 2,000, it can cut through most types of dirt at a faster rate than most entry-level pressure washers.

We also like the Turbo nozzle that provides a 360-degree washing mechanism that can be used across home surfaces such as walls, patio, driveway.

Pro Tip – Register your tool on the Worx website to get an additional year of warranty.

#3 - Best 1600 PSI Pressure Washer: STANLEY SHP1600

Pioneer of tape rule, utility knife, carbide blade, and several mechanical tools that are ubiquitous today, Stanley Tools began its operations in 1943 in Connecticut, USA. It’s one of the oldest manufacturers in the business.

Which is The Best PSI for Pressure WasherBest 1600 PSI Pressure Washer: STANLEY SHP1600

Pros
  • 14-ounce detergent tank for soap washing
  • Variable turbo nozzle with various spray angles (no additional nozzle needed)
Cons
  • Soap washing is cumbersome

Pressure Washer Review

The feature that stands out in this Stanley portable pressure washer is the variable turbo nozzle. You don’t have to replace the nozzles every time you want a different flow/angle of spray. Just twist the nozzle and you are done.

Although this 1,600 PSI pressure washer boasts of a detergent tank, we are not too impressed with the way it works. Setting up the soap dispenser is a lot of work, plus the wand just sputters the liquid instead of constant soapy water. Not really efficient for car washing but will get other tasks done.

Pro Tip – Open your faucet all the way to get the maximum pressure.

#4 - 1800 PSI Pressure Washer: Cat Electric Pressure Washer

Who doesn’t recognize the CAT (Caterpillar) brand? If you don’t, just know that CAT is a leader when it comes to putting technology and high-precision engineering together to produce smart tools. This 1,800 PSI pressure washer is a great example.

Which is The Best PSI for Pressure Washer1800 PSI Pressure Washer: Cat Electric Pressure Washer

Pros
  • Robust 5-piston pump for heavy water flows
  • 4 metal spray tips and metal wand
  • Long 35-foot cord solves the issue of a distant power outlet
  • Large detergent bottle
Cons
  • Heavier (29 pounds) than other tools in this PSI and price range

Pressure Washer Review

Of all quality pressure washers under 2,000 PSI that you have seen, this one will be slightly different.

Evidently, CAT has a very different approach. It has a large detergent bottle that provides constant soapy water for foamy cleaning.

It also has a stronger pump that can jet spray up to 2 gallons of water per minute. This will ensure that even larger surfaces are cleaned in less time. The metal wand and tips will last for years, and definitely longer than the plastic ones that are more common these days.

Instead of TSS, it has a push button interface. This is not exactly power efficient.

Note – CAT 1800 is marketed as a tool with 3,600 units. As we noted before, it’s just a product of PSI and GMP.

Cons
  • Warranty lasts only a year but covers machine, hose, wand (bumper to bumper)

Pressure Washer Review

This AR Blue Clean tool is a good pressure washer for car, home use, and entry-level commercial purposes. This is because it does not have many fringe features and instead focuses on a high-powered pump that guzzles water and ejects it out at a faster rate. The 1,900 max PSI with 1.5 GPM is enough to cut through dirt on most surfaces.

The highlight is that it has two different wands for your convenience. If one malfunctions, you have a backup. No need to replace the entire unit.

Pros
  • Detergent bottle also acts as a foam machine
  • 4 quick-connect nozzles
  • Strong built; strong materials such as brass hose connector
Cons
  • Foam dispenser sometimes does not provide the required pressure

Pressure Washer Review

The best part of this 2,000 PSI electric pressure washer is its high rating. Everything else is similar to the other tools we have seen above.

The detergent bottle, as an exception, produces foam with equal pressure. But we have noticed the pressure is not constant when you use liquid soap.

As the pressure setting and price increases, you get better benefits too such as a longer hose.

Pros

Cons

Pressure Washer Review

This 2,700 PSI pressure washer has more power thanks to its gasoline-driven 4-stroke motor. Although it makes some noise during operation, you get a lot more pumping power than pulls a lot of water and jets with more pressure and flow. It has a GPM of 2.3, the highest so far on this list.

That’s not all; the steel body is heavy-duty and strong enough to last for years. Plus, the four-nozzle set makes all your tasks – from washing your patio to the floor of a greasy garage. This is a top pressure washer for decks, greasy floors, paved floors, and blocks of any materials including stone.

Moreover, the power dial spray that changes the flow setting according to the surface (car and wood, for example) is another great feature that we love. Despite the shortcomings, this pressure washer for deep cleaning packs a punch.

Best PSI for Pressure Washer FAQs

Still have questions? Check out these frequently answered questions (FAQs) about pressure washers, PSI settings, and more.

Is a higher PSI pressure washer better?

Yes, for most cases. While a high PSI pressure washer will give you more cleaning power, it may or may not be ideal for the tasks at hand. For instance, using a high pressure washer for car washing may harm the paint. We recommend the CAT 1,800 for car washing.

What is the highest PSI pressure washer you can buy?

The highest PSI pressure washer is 5,000. There are two notable tools with 5,000 PSI: NorthStar Model# 1571493 and Simpson WaterShot WS5050H.

How much PSI can hurt you?

Anything above 2,000 PSI should be dealt with care and precaution. Even so, if you place your fingers in front of an electric water pressure wand, you may get hurt. According to Consumer Product Safety Commission, over 6,000 people are affected by injuries caused by pressure washers. To avoid mishaps, we recommends pointing the nozzle away from your body and using the widest spray option among others.

What's the best PSI for a residential pressure washer?

The PSI range of 1,600 to 3,000 will be sufficient for most residential washing purposes.

How many PSI do you need to clean concrete?

You will need 3,000 PSI or more to clean dirt off concrete surfaces. You may also need foam and a concentrated water spray nozzle to get rid of harder stains from concrete slabs.

How many PSI do you need to clean concrete?

A PSI setting in the range of 1,600 and 2,700 is sufficient for washing the house and associated nooks and corners. Use soap and a suitable spray angle to get the best results. The broom option in the Simpson MegaShot will be a great choice for floor cleaning.

How much PSI do you need to pressure wash the driveway?

Anything above 2,000 PSI will be good enough to pressure wash the driveway. You will also need a foamer or soap dispenser to get better results.

Which is the best PSI for car wash? What PSI is safe for washing cars?

The best PSI for car wash is in the range of 1,600 to 2,700. If you are looking to wash the tires and other under-the-hood areas, you may need slightly higher PSI and soapy water. Anything above this range will harm the paint and other sensitive surfaces. As an expert, we recommend using the garden hose to wash your cars to avoid any harm to the car’s surface. If you want to use a washer, consider the widest spray angle and the lowest pressure setting.

Which is the best PSI for vinyl siding?

Anything around 3,000 PSI is sufficient for vinyl siding. Just use the right spray angle and soap liquid for best results.

How much PSI do you need to wash decks?

Anything in the range of 2,000 and above will be sufficient to wash decks. This will also depend on the type of dirt you are trying to wash; grime, dirt, and mud can be easily cleaned with a low PSI. Sap, mildew, fungus, algae, grease, and other harder substances will require more pressure and concentration.
