A pressure washer is the rare tool that pays for itself in a single weekend, and the rare tool that disappoints just as quickly. The problem is almost never the number printed on the front of the box. Two machines can both claim 2,000 PSI and clean nothing alike, because flow rate and the wand end of the machine do most of the actual work. If you are shopping for the best pressure washer for driveways, cars, decks, and siding, the numbers worth comparing are gallons per minute, detergent draw, hose quality, and the nozzles that come in the box.
This guide covers six products: four complete pressure washers split between electric and gas, plus a replacement hose and a wand nozzle that upgrade a machine you already own. Every specification below comes from the manufacturer's product data, and each card links to the exact model shown so you can confirm current details yourself.

Quick answer
The Westinghouse ePX3100 Electric Pressure Washer is the strongest fit for most home driveways, cars, and patios because it combines a 1.76 max GPM rating with 2300 max PSI, an onboard soap tank, a pro-style steel wand, and a five-nozzle set in an electric package with anti-tipping technology. Choose the Westinghouse WPX3200 Gas Pressure Washer instead when you need the higher flow of a gas unit for large, repeated, or commercial-scale jobs.
Pressure washers worth comparing
The real differences between these machines are flow rate, detergent delivery, hose and wand quality, and whether the power source suits how often you actually work. A weak-flow machine with a great nozzle will still out-clean a strong-flow machine with a toy wand, which is why the two upgrades below belong in the same conversation as the washers.

How these products were compared
This guide compares rated flow in gallons per minute, rated pressure in PSI, the detergent system, wand and hose quality, and power source and portability. Product names, images, and retailer links are matched to the same product, so every card points to the model shown.
The figures here are manufacturer ratings rather than bench measurements, and that distinction matters. A 1.2 GPM washer and a 2.5 GPM washer can share a similar PSI figure while cleaning at completely different speeds, because flow is what carries soil off the surface. Treat the ratings as the starting point for comparison and confirm the details on the product page before you buy.
How to choose the right pressure washer
Start with flow, then look at pressure. Gallons per minute is the volume of water doing the work, and PSI is how hard that water arrives. A unit rated near 2.5 GPM moves roughly twice the water per minute of a unit rated near 1.2 GPM, which is the difference between rinsing a driveway in a few passes and standing there watching a wet stripe. If two machines sit at similar prices, the one with the higher GPM is usually the one that finishes the job first.
Then decide on the power source, because it shapes everything else. Electric washers like the Westinghouse ePX3100, the Kärcher K5 Power Control, and the CRAFTSMAN CMEPW1700 plug into a household outlet, need no fuel, and start with a switch. They suit cars, patios, siding, fences, and most residential driveways. Gas machines like the Westinghouse WPX3200 trade that convenience for higher rated flow and no cord to manage, which is why they show up on larger properties, boat hulls, and jobs where you are running the machine for hours rather than minutes.
Detergent delivery is the next filter. A washer with an onboard soap tank, such as the ePX3100 or the WPX3200, lets you apply cleaning solution without dragging a separate sprayer around. Downstream injection through a wand works, but a tank you can refill on the machine is simpler and less likely to clog. If you plan to clean siding, fences, or a moldy patio, the soap function is not a bonus feature, it is the reason the job comes out even.
Finally, look at the hose and the wand, because those are what your hands touch every single time. Hose length decides how far you can reach before moving the machine, which is why a 32 ft hose on the Kärcher K5 and a 50 ft replacement hose like the Simpson 41028 change the rhythm of a job. Wand quality decides whether the tool feels like equipment or a toy. If you already own a washer with a stiff, kinking hose or a flimsy wand, replacing those parts is often cheaper and more satisfying than replacing the whole machine. Our nozzle and wand guide covers those upgrades in more detail.
Westinghouse ePX3100 Electric Pressure Washer
The Westinghouse ePX3100 is the pick for most households because its spec sheet lines up with the work most people actually do. It is rated at 2300 max PSI and 1.76 max GPM, which puts it above the small 1.2 GPM class while staying on a standard household outlet. It ships with an onboard soap tank for detergent draw, a pro-style steel wand rather than a plastic one, and a five-nozzle set that covers the usual spread of tasks from a wide fan for rinsing to a tight stream for concrete. Anti-tipping technology addresses the practical annoyance of a tall electric unit that wants to fall over when you pull the hose.
The trade-off is the one every electric washer shares: it is not a gas machine. If your normal job is a two-car driveway, a full fence line, and a boat hull in the same afternoon, the rated flow of the gas WPX3200 is the better match, and electric units generally expect you to work within their duty cycle rather than run them flat out all day. For cars, patios, decks, siding, and a typical suburban driveway, the ePX3100 covers the job with a soap tank and a real wand included.
Alternatives to consider
The Westinghouse WPX3200 Gas Pressure Washer is better suited to large properties, boat owners, and anyone who cleans for hours at a time, with a rated 3200 PSI and 2.5 GPM, an onboard soap tank, a spray gun and wand, and a five-nozzle set. The Kärcher K5 Power Control is a stronger fit when hose reach and wand choice matter most, since it is rated at a maximum 2500 PSI and 1.55 GPM and arrives with a 32 ft hose and two spray wands.
The CRAFTSMAN CMEPW1700, the Simpson 41028 hose, and the Upgraded Jet Nozzle for Garden Hose Power Washer Wand cover the other end of the market. The CRAFTSMAN is a compact, lightweight cold-water corded unit rated at 1700 PSI and 1.2 GPM, which suits car washing, patio furniture, and light garage cleanup where a smaller machine is easier to store and handle. The Simpson hose is a 50 ft, 3/8 inch replacement rated to 4500 PSI, which makes it a sensible upgrade for a short or stiff factory hose on a gas machine. The jet nozzle is a low-cost change for a garden hose wand setup that needs a more concentrated spray.
Day-to-day use and maintenance
Match the nozzle to the surface before you pull the trigger. A tight, high-impact stream belongs on concrete, not on siding, deck boards, or a car's clear coat, and the five-nozzle sets included with the ePX3100 and WPX3200 exist so you can move up and down that range without changing machines. Work top to bottom on vertical surfaces and rinse in the direction the water wants to run, so you are not pushing dirt back into what you just cleaned.
After a job, flush the detergent system rather than leaving soap sitting in the tank or line. Run clean water through the machine and the wand until the output runs clear, which is the simplest way to avoid the clogged injection systems that make people give up on the soap function entirely. Coil the hose without sharp bends, check the O-rings and connections for wear, and store the unit somewhere it will not freeze.
Cold water is the norm for all four machines here, including the CRAFTSMAN, and that is worth remembering when a job seems to stall. Cold water plus the right detergent plus a few minutes of dwell time does more than raw pressure ever will.
Safety matters more than any spec. Never point the wand at people or pets, keep water away from electrical outlets and fixtures, and be careful around window seals, siding joints, and anything already loose. A pressure washer removes paint, caulk, and grime with equal enthusiasm, so test an inconspicuous area first.
Buying checklist
- Measure the longest run you need to reach, from the outlet or fuel storage spot to the far edge of the driveway, then compare it against the hose length included with the machine.
- Choose rated GPM based on normal use rather than an occasional edge case, since flow is what determines how fast the work goes.
- Confirm that the exact model includes the detergent system you want, whether that is an onboard soap tank or downstream injection.
- Read the cleaning and maintenance instructions, including winterizing steps and any duty cycle guidance.
- Verify the current retailer price, availability, and return terms before ordering.
Final recommendation
Choose the Westinghouse ePX3100 Electric Pressure Washer when you want one machine for cars, patios, siding, and a typical driveway, with a soap tank, a steel wand, and a five-nozzle set included. Choose the Westinghouse WPX3200 Gas Pressure Washer when your regular jobs are large enough that the rated 2.5 GPM flow and freedom from a cord are worth the extra weight and noise. Choose the Kärcher K5 Power Control when hose reach and two wands matter most, the CRAFTSMAN CMEPW1700 when light, compact, and easy to store is the priority, and the Simpson 41028 hose or the Upgraded Jet Nozzle when the machine you already own is fine and only its hose, wand, or nozzle is holding it back.
