Pressure washers have many uses around your home, from cleaning decking and siding to washing cars, removing mold, cleaning lawn equipment, and more. The secret is in their tremendous power. While the average garden hose emits water at pressures under 40 psi, pressure washers—thanks to their gas or electric motors—shoot out water at an average of 1,000 psi to 4,000 psi, depending on the model.

These versatile tools come in both electric and gas versions—gas-powered models are typically more powerful—and a range of sizes. To simplify the buying process, we researched the most popular pressure washers available today and then whittled down the choices to the best for the categories most important to the average homeowner.
One of the best pressure washers on the market is the Simpson Cleaning MegaShot Gas Pressure Washer. This powerful machine houses a Honda GC190 engine for reliable power. And it delivers a whopping 3,200 psi using 2.5 gallons per minute (gpm), making it ideal for use on your house, driveway, patio furniture, car, painted surfaces, and more.

This pressure washer has a heavy-duty welded steel construction frame and 10-inch pneumatic tires for increased stability. It weighs in at 66 pounds. The MegaShot is equipped with a 25-foot kink-resistant hose, a reliable OEM axial pump, and an ergonomic spray gun. And it includes five stainless steel quick-connect nozzles for a variety of applications. This reliable, sturdy, and powerful gas-powered pressure washer is easy to set up and start.
Electric power washers are easier to maintain—no oil changes necessary—but the downside is you have to be in close proximity to an electrical outlet. One of the most highly rated electric models today is the Sun Joe Electric Pressure Washer, which delivers 2,030 psi at 1.76 gpm. This affordable unit is equipped with dual detergent tanks, and it comes with five quick-connect spray tips to help you tackle all sorts of cleaning tasks.

The Sun Joe Pressure Washer features a 20-foot high-pressure hose, a 34-inch extension wand, and a 35-foot power cord. And it even comes with a garden hose adapter. You can store two different types of detergent in the dual chambers, switching between them with the selection dial. This versatile power washer can be used for a variety of easy and tough tasks. Our testers have put it to work on siding, decking, cars, and more.
Want to wash your car without scrubbing it by hand? A pressure washer like the Karcher K5 will get the job done in no time. This electric power washer delivers up to 2,000 psi at 1.4 gpm, and it has an onboard detergent tank for easy soap application. The Karcher K5 has up to 40 times as much pressure as a garden hose, and it includes two wands—the Vario for everyday cleaning and the DirtBlaster for tough jobs.

The Karcher K5 has a water-cooled induction motor—a system that can help the motor live five times longer, and it comes with a 25-foot high-pressure hose and a 35-foot power cord. This 32-pound pressure washer is a great choice for washing cars, trucks, and SUVs, but it can also be used on tougher jobs like cleaning driveways.
Will you just need to tackle small jobs with your pressure washer? In that case, a more affordable model like the Greenworks Pressure Washer will serve you just fine. This budget-friendly model dials back the power to 1,500 psi and 1.2 gpm, making it ideal for smaller projects, such as cleaning patio furniture and washing your car.

This lightweight electric pressure washer weighs just under 16 pounds and includes a 35-foot power cord and a 20-foot high-pressure hose. It can be used vertically or horizontally for greater stability, and it comes with 25- and 40-degree quick-connect tips for different spraying levels. It's a great value, but it's still powerful enough to clean siding, driveways, and more.
Gas pressure washers are typically more powerful than electric models due to their engines. And if you’re looking for a top-rated gas model that packs a mean punch, the Simpson PowerShot Pro Gas Pressure Washer may be the best power washer for you. This heavy-duty pressure washer delivers 4,400 psi to tackle even the toughest jobs at 4 gpm.

This unit gets its power from a 420 cc engine, and it’s made from solid steel for durability. The washer’s kink- and abrasion-resistant hose is 50 feet long, and the 13-inch tires make it easy to steer across various terrains, including pavement or grass. The PowerShot Pressure Washer comes with five quick-connect nozzle tips that can be used for all sorts of applications, such as wood restoration and graffiti removal.
