Best Pressure Washers Updated November 2018

Conclusion

Pros

Cons

Champion

3200-PSI 2.4-GPM Dolly-Style Gas Pressure Washer
Check Price at: 1 store
One customer said it best: Mind. Blown.
Clear instructions and an easy, single-pull start get it up and running in no time. 2 ½-gallon detergent dispensers are attached for fewer refills.
There’s a break-in period. The hose is stiff and the engine may vibrate the first few hours of use.

Annovi Reverberi

Blue Clean AR383
Check Price at: 1 store
Good for hosing down grills, fences, and lawn mowers.
A long hose (20 feet) for hard-to-reach scum. It conserves 80% more water than standard power washers.
A trigger lock would be nice to have. Plastic hose adapter leaks. A brass male-to-male adapter is a quick, cheap fix.

Sun Joe

SPX3000 Pressure Joe
Check Price at: 1 store
Nearly 6k pressure washer reviews and a 4-star rating.
We loved the variety of nozzle tips and their click-in-place storage behind the soap dial. Simply turn this dial to switch between 2 dispensers and reduce refills.
Some of the lower ratings are due to a plastic hose connector, which Sun Joe has since replaced with a metal piece.

Generac

OneWash Gas Powered
Check Price at: 1 store
Includes a surface cleaning attachment that scrubs driveways and walkways with rotating nozzles and tough bristles.
Extremely powerful—3,100 PSI. The preset dials (car, wood, concrete, and soap) make it easy to adjust pressure based on what you’re cleaning.
This Generac pressure washer is loud and the fuel requires more maintenance.

GreenWorks

13 Amp Electric
Check Price at: 1 store
Don’t expect the GreenWorks pressure washer to transform your entire driveway, but it’ll target dirt and mildew on siding and pavers.
Most portable pressure washer—just shy of 17 pounds with a 35-foot power cord. Excellent coverage under a 4-year warranty.
Less powerful than the others on our list (1,500 PSI). Air bubbles can affect performance.

Pressure washers offer instant gratification, but only the ones that actually work. A power washer isn’t an everyday purchase, so it can be difficult to narrow your options. We weighed the pros and cons of electric vs. gas pressure washers. We deciphered the ratings for you and learned what PSI, GPM, and CU meant. We essentially swapped our bedtime reading for pressure washer reviews and manuals, so you can save time on research and see results immediately.

Pressure washer reviews guide 

Sometimes you don’t realize how dirty something is until you give the pressure washer a shot. These machines can turn gray houses white again, make dusty patio furniture look like new, and even cut through years of built-up grease on driveways, lawn mowers, and grills.

Until now, you might have thought the garden hose would do the trick and it probably helped—a little. However, pressure cleaners are much more powerful and effective than your average hose. They even conserve more water.

When it comes to boosting curb appeal and preparing your home for resale, power washers deliver a high ROI every time. We can just about guarantee that you’ll be amazed by the results, especially if this is your first time using one. We have to admit. Pressure washing can be addicting. You may very well spend a whole day pressure cleaning everything in sight.

Pressure washers conserve more water than garden hoses. An average garden hose has 280 cleaning units while pressure washers have at least 1,000 cleaning units.”

Electric vs. gas pressure washers

Electric pressure washers are quieter, lighter, and cleaner than gas-powered machines. Because they don’t emit fumes, electric power washers are better for the environment and your health. You’ll be able to remove dust, dirt, and debris from smaller surfaces, like grills, patios, and lawn mowers. Because they use less pressure than gas power washers, electric pressure washers are safe to use on vehicles and bicycles.

Gas pressure washers are definitely more powerful than their electric counterparts. They can cut through grease and grime in addition to dust and dirt. Your garage, driveway, and siding will never look better after a good pressure washing with a gas-powered machine. Power comes with a price though. Gas pressure washers are often more expensive, they emit fumes, and they require more maintenance.

Our recommendation is to use gas sparingly—once or twice a year—when you really need to deep clean a large area. For all other occasions, use an electric power washer.

Best gas pressure washer CHAMPION 3200-PSI 2.4-GPM DOLLY-STYLE GAS PRESSURE WASHER

The Champion pressure washer will boost curb appeal in no time at all. Customers have reported a job well done on wooden decking, vinyl siding, and concrete garage flooring. It’s the most powerful pressure washer on our list and you’ll have a hard time finding anything above 3,200 PSI in the residential pressure washer market. Although heavy, customers love how sturdy the wheels are on this thing. That means you can clean the whole house from top to bottom, front to back.

4 Major factors to consider

PSI

Water pressure is measured in pounds per square inch (PSI). You should expect about 1,500 to 2,000 PSI when shopping for an electric power washer. Although, the Sun Joe pressure washer is exceptional with a generation of 2,030 PSI. Gas-powered units are more powerful with 2,000 to 3,000 PSI. At 3,200 PSI, the Champion pressure washer stands apart from other gas-powered machines.

Cleaning units

Performance is an important factor in finding the best pressure washer. Performance may sound subjective, but it can actually be calculated by finding the cleaning units. Simply multiply the pressure (PSI) by the gallons per minute (GPM). Here are the cleaning units of the top five pressure washers:

Adjustability

You’ll want to adjust the water flow and pressure according to the task at hand. It doesn’t take as much pressure to wash a car as it does a driveway. In fact, you could actually peel the paint off your car if you’re not careful. Some washers, like the Champion and Sun Joe pressure washers, include interchangeable nozzles that attach to the end of the spray wand. These nozzles are often labeled from zero (targeted quarter-size stream) to 40 degrees (gentle fan spray). You could use a zero-degree nozzle for removing packed debris from tight spaces (i.e. sidewalk cracks) and a 40-degree nozzle for larger areas that are more fragile (washing windows for example). A 65-degree soap nozzle is sometimes included with your purchase.

Portability

Portability is prized when you’re working around the house. You’ll want a power washer with wheels unless it’s unusually small, like the 17-pound GreenWorks pressure washer. Still, 17 pounds can feel like 40 after you’ve been lugging it around for a few hours. Electric machines are always lighter than gas-powered pressure washers. The ones we reviewed weigh 17 to 30 pounds. The gas pressure washers are much heavier—60 to 70 pounds—and that’s before you even fill the machine with fuel. However, because they’re gas-powered, you won’t be tethered by a short power cord. Rubber tires often replace plastic wheels on these machines, making them easier to navigate through grass.

The 25-degree nozzle is the most versatile. You can safely wash vehicles, outdoor furniture, and walkways.”

Pressure washing do’s and don’ts

  • Don’t leave nozzles attached to spray wands after use. Wands will rust if they don’t dry completely.
  • Do use a pump protector liquid to extend the life of your power washer.
  • Don’t use a gas-powered pressure washer on light jobs, like your car or patio furniture.
  • Do keep the spray wand 18 inches away from any surface to avoid damage.
  • Don’t pressure wash siding if it’s from the 70’s or earlier. Call a professional first. Paint can peel and you don’t want lead-based paint chips floating around the yard, especially one inhabited by children or pets.
  • Do slow down and overlap your strokes to avoid lines.
  • Do use hot water on grease- or oil-stained pavement. However, refer to your owner’s manual on this one. Some machines can be used with only cold water.
Best electric pressure washer SUN JOE SPX3000

The Sun Joe pressure washer is certainly popular with 5,743 customer reviews and a 4.5-star rating. Our team was curious what all the hype was about, so we brought it into our lab and put it to the test. Our editor—who had never used let alone assembled one of these contraptions before—followed an easy video tutorial to put it together. She and our director of operations used the Sun Joe and all of its colorful, quick-change nozzles to erase chalk off of asphalt and blast debris from our office’s entrance. After it left our editor’s Nissan sparkling clean, everyone started putting in their bids to take the Sun Joe home.

Want to boost curb appeal? Pressure washing is a worthwhile task to add to your seasonal home checklist.”

Frequently asked questions

What is the best brand for pressure washers?

We narrowed our top five to some leading brands in the pressure washer vertical: Champion, Annovi Reverberi, Sun Joe, Generac, and GreenWorks. Champion and Generac are known for their powerful products from pressure cleaners to portable generators. Annovi Reverberi has engineered some ultra-efficient pumps for the agriculture market. Sun Joe and Greenworks specialize in lawn equipment.

What is the best pressure washer to buy for home use?

The gas-powered Champion is the best pressure washer for home use. It’s backed by 3,200 PSI and is, therefore, the most powerful one on our list. At 7,680 cleaning units, it can handle just about any type of dirt, debris, grease, and grime you put in front of it. Although it’s heavy, this dolly-style pressure washer is portable enough to clean the whole house front to back.

What PSI pressure washer to clean concrete?

Depending on how dirty your driveway is, you’ll need a 2,000 to 3,000 PSI pressure washer to clean concrete. Gas-powered pressure washers are more effective for this type of heavy-duty job.

What PSI is needed to power wash a deck?

You’ll want to use a maximum of 1,500 PSI to wash a deck. Higher pressure than that could damage the wood. Just about any electric pressure washer will do the trick.

What pressure washer is best for car cleaning?

The Sun Joe is the best pressure washer for car washing because it’s portable, electric, and adjustable. 2,300 PSI is more than enough to wash a vehicle and you’ll get to switch between five quick-change nozzles as you wash wheels and the grill to the hood and windows. Use the soap nozzle and two detergent dispensers for a quick car wash at home.

What PSI is safe for washing cars?

You don’t need a ton of pressure to wash a car. We’d recommend sticking to 2,000 PSI with a 25-degree nozzle. If you use too much pressure or too targeted of a stream, you’ll risk peeling paint or denting the car.

What is a good PSI for a pressure washer?

The power washers we reviewed range from 1,500 to 3,200 PSI. Electric pressure washers max out at 2,000 PSI while gas pressure washers boast 3,000+ PSI.
