Best Pressure Washers (2026)

A gas washer earns its place on flow. The WPX3400 pushes 2.6 GPM at 3400 PSI, which multiplies out to about 8,840 cleaning units, roughly three times the 2,400 or so that the best-rated electrics in this guide manage. That is the difference between spending ten minutes on a driveway and an hour.

The 212cc overhead-valve engine drives the pump directly, and a 25-foot abrasion-resistant hose, a metal gun and five quick-connect nozzles come in the box, along with an onboard soap tank. Compared with the Westinghouse WPX3400e, it moves more than twice the water, but it is louder, heavier, and needs fuel, oil and a pull start. Against the electric models it is the choice when time matters more than convenience.

Upkeep is the usual small-engine routine: change the oil, use fresh stabilized fuel, check the spark plug and air filter, and winterize the pump by draining it or running pump antifreeze through it so freezing does not crack it. Wear hearing and eye protection, since 3400 PSI can injure skin as well as strip paint, and never leave the trigger closed with the engine running because the pump heats up quickly.

Greenworks aims this one squarely at the gas-versus-electric argument. A 14 amp TruBrushless motor generates 3000 PSI and up to 2.0 GPM, and the listing says the figures were verified by an independent lab, which is worth more than a raw peak claim because it ties the numbers to a test. JETTFLOW technology is described as delivering up to 50% more flow for reaching high areas and quick rinsing.

The 2.0 GPM maximum is still short of the WPX3400 gas machine's 2.6 GPM, and it is a max, not a sustained figure at full pressure, so read 3000 PSI times 2.0 GPM, or 6,000 cleaning units, as a ceiling. Against the Westinghouse WPX3400e, this one lists a higher flow, though the Westinghouse states a lower rated flow honestly.

Ownership is simple compared with gas: no oil, no fuel, no pull cord. An axial cam pump is common in electric machines and is not normally rebuildable, so protect it by never running it dry or with the trigger closed, draining it before a freeze and using clean water. Keep the extension cord short and heavy-gauge.

What makes this Westinghouse useful is that it states both sets of numbers. The 3400 PSI and 2.0 GPM figures are maximums at different settings, while the rated output of 3000 PSI at 1.1 GPM is what the machine delivers working under load. Multiply the rated figures and you get about 3,300 cleaning units, a realistic number for comparison.

That is why it sits between the compact electrics and the gas washer: more rated pressure than the 2000 PSI ePX3500, but only 1.1 GPM, so it blasts a small area hard rather than rinsing a large one quickly. The true brushless 120V motor and axial three-piston auto-stop pump are meant to be low maintenance, and the auto-stop shuts the motor when you release the trigger.

Treat the pump as a consumable that lasts if you look after it. Drain it before freezing weather, attach a hose with enough flow so it never starves, and use the soap tank at low pressure rather than through the high-pressure nozzle. The 25-foot hose and five quick-connect nozzles are included.

Here the engineering priority is portability: it stands 16.5 inches tall, weighs about 19 pounds and has four quick-lock wheels and anti-tipping features, so it rolls around a yard and stores in a closet. The rated output of 2000 PSI at 1.2 GPM works out to about 2,400 cleaning units.

That puts it level with the Sun Joe SPX3000 in this guide and well below the 3000 PSI class, so it suits cars, patio furniture, grills, siding and light concrete, not heavy driveway grime. The 20-ounce onboard soap tank and 25-foot braided nylon hose are included. Against the Greenworks 2100, it is better documented on its rated output.

To keep it lasting, coil the braided hose loosely, store it where it will not freeze, and let the water drain before storing. Check the quick-connect o-rings and the hose ends for leaks each season. It is a sensible first machine, with no oil or fuel to manage.

Sun Joe labels this 2500 PSI max but lists the working figure as 2030 PSI at 1.2 GPM, a candid split that matches what the machine actually delivers. At about 2,436 cleaning units it is a near match for the Westinghouse ePX3500, with the main difference being the tools: a 34-inch stainless steel lance with solid brass fittings.

A longer lance means you stand upright instead of stooping, which matters on a long job such as a fence or deck. Five quick-connect tips cover everything from the 0-degree pencil jet to the soap nozzle. The corded 120V design suits small to medium jobs near an outlet.

Keep the nozzle tips away from wood and car paint at close range, and use the 25 or 40 degree tips for general rinsing. Replace the o-rings in the quick-connect when they weep, store it drained, and keep the extension cord rated for the load. It is a strong all-rounder for a modest budget.

This is the plain-vanilla option: 2100 PSI at 1.2 GPM, push-button start and an integrated GFCI that cuts electrical power if a fault occurs. The maker positions it for medium-duty jobs such as fences and decking.

Multiply the headline figures and you get about 2,520 cleaning units at the labelled maximum, but the listing does not separate rated from peak output, so treat that as a ceiling. Compared with the Westinghouse ePX3500, it gives less detail on how the figures were derived, while the Westinghouse spells out rated output clearly.

It has no oil, spark plugs or air filter to maintain, which makes it an easy machine to own. Drain it after each use, avoid kinks in the hose and use fresh water. As a starter machine it handles cars, furniture and light siding well enough.
