I have spent twelve years detailing cars and boats out of a van in Tampa, which means I have pressure washed more driveways, decks, and boat hulls than I can count, and I have burned through more than one cheap machine learning what actually matters. Most people shopping for a corded washer get sold on the PSI number printed on the front of the box, and that number tells you almost nothing about how the machine cleans. This electric pressure washer comparison puts four corded units side by side, explains what their flow rates mean on a real driveway, and stays honest about where each one gives something up.

The best pick for most people here is the Westinghouse ePX3100s, because it matches the higher-flow Westinghouse on GPM and includes a foam cannon and a turbo nozzle, which is the accessory kit you would otherwise buy on its own. If you want the most pressure and the most nozzles in the box, the ePX3100 is the other half of that argument. If you want the longest hose and the brand with the strongest reputation for durability, the Kärcher K5 Power Control is the one you will end up defending in the comments.

Westinghouse ePX3100s Electric Pressure Washer, 2100 Max PSI 1.76 Max GPM with Foam Cannon and Turbo Nozzle, for Cars/Fences/Driveways/Home/Patios
Same 1.76 max GPM flow as the bigger Westinghouse, plus a foam cannon and turbo nozzle in the box
2100 max PSI is the second lowest here, and no onboard soap tank is listed

Westinghouse ePX3100 Electric Pressure Washer, 2300 Max PSI 1.76 Max GPM with Anti-Tipping Technology, Onboard Soap Tank, Pro-Style Steel Wand, 5-Nozzle Set, for Cars/Fences/Driveways/Home/Patios
Highest flow of the group at 1.76 max GPM, 2300 max PSI, onboard soap tank, steel wand, five nozzles
No foam cannon and no turbo nozzle, so the two accessories I use most cost extra

CRAFTSMAN Electric Pressure Washer, Cold Water, Lightweight Corded Power Washer for Cars, Driveways, Patio and Garage, Powerful 1700-PSI, 1.2-GPM, Compact, Easy to Use (CMEPW1700)
Lightweight, compact, corded, cold water, and simple enough to hand a first time owner
1.2 max GPM is the lowest flow here and lands under the 1.5 GPM floor I would set for anything past light duty

Kärcher Pressure Washer, K5 Power Control, Max 2500 PSI, 32 ft. Hose, 2 Spray Wands - 1.55 GPM
2500 max PSI, a 32 ft hose, two spray wands, and the best hose length of the group
Most expensive of the four, and 1.55 max GPM still trails both Westinghouse units

What the numbers on these boxes actually mean
Two of these washers advertise 1.76 max GPM, one advertises 1.55, and one advertises 1.2. That spread matters more than the PSI spread across the whole group. Cleaning is flow working with pressure, and flow is the part you feel as speed. A 1.76 GPM machine lays down roughly half again as much water per minute as a 1.2 GPM machine, which means fewer passes, less streaking, and less time standing in the Florida sun waiting for a nozzle to do work it cannot do.
The pressure figures run 1700, 2100, 2300, and 2500 max PSI. Every one of those is a maximum measured at the pump, not a working pressure at the surface you are cleaning. Put a wide fan nozzle on a 1700 PSI machine and you have a safe tool for car paint, patio furniture, and vinyl siding. Put the same narrow nozzle on a 2500 PSI machine and you can etch concrete or peel paint off a fence if you get careless. Pressure is the thing you aim. Flow is the thing that cleans.
The spec nobody prints in big letters is detergent draw. Two of these machines give you a real soap path: the ePX3100s through its foam cannon, the ePX3100 through its onboard soap tank. If a washer cannot pull soap out of a bottle on its own, you are rinsing with extra steps.
Westinghouse ePX3100s: the one I would hand a car person
The ePX3100s is rated 2100 max PSI and 1.76 max GPM, and it ships with a foam cannon and a turbo nozzle. Those two accessories are the entire reason this is my pick for anyone whose washer is going to spend most of its life on vehicles. A foam cannon is how you get a thick, clinging layer of soap on paint so the dirt lifts before you touch it. A turbo nozzle is how you turn the same machine into a concrete tool for the driveway apron and the sidewalk. The name lists cars, fences, driveways, home, and patios as the intended work, and that accessory pair is exactly why.
What you give up is straightforward. At 2100 max PSI this is the second lowest pressure figure in the group, and no onboard soap tank is listed, so detergent duty falls to the foam cannon. For car work that is not a loss at all. For a greasy garage floor, where you want to flip between soap and rinse without swapping bottles, it is a small annoyance. The important part is that the 1.76 GPM flow matches the higher-priced Westinghouse, so you are not trading cleaning speed for the accessories. You are trading a little peak pressure you probably were not going to point at paint anyway.
Westinghouse ePX3100: more pressure, more nozzle, no foam cannon
The ePX3100 is the machine the ePX3100s is built from, and on paper it is the better washer. It is rated 2300 max PSI and 1.76 max GPM, so it beats everything else here on the combination of pressure and flow. It adds anti-tipping technology, which sounds like a marketing line until you have watched a narrow corded unit tip over on a sloped driveway and yank its own hose off the inlet. It carries an onboard soap tank, a pro-style steel wand, and a five-nozzle set.
That wand and nozzle package is the part I care about. Wands that feel like toys are a daily irritation, and a steel wand with a proper quick-connect collar is the difference between a tool and a toy. Five nozzles in the box also means you are not guessing which one you need; you have the full spread from a wide fan for rinsing a car to a narrow jet for a stubborn stain on concrete.
The catch is the accessory gap. There is no foam cannon and no turbo nozzle in the box, and those are the two add-ons that change what the machine can do. Buy them separately and you have spent the difference between this and the ePX3100s, and you end up with a slightly stronger washer plus the same kit. If you mostly wash concrete and siding rather than vehicles, that trade works in your favor. If you are a car person, it does not.
CRAFTSMAN CMEPW1700: the light duty machine, and I mean that kindly
The CMEPW1700 is rated 1700 PSI and 1.2 GPM, cold water only, and it is designed to be light and compact with simple controls. There is a real customer for this machine and I do not want to talk anyone out of it. If your list is a car every other weekend, a set of patio chairs, a grill, and the walkway to the front door, this will handle all of it, and it will be the easiest of the four to carry up a flight of stairs or hang on a garage wall.
The problem is the flow rate. At 1.2 max GPM this is the only machine in the group under the 1.5 GPM floor I use as a hard cutoff. Flow is what flushes loosened dirt away instead of just moving it around, and at 1.2 GPM you are going to make slow, overlapping passes and you are going to use more water than you think, because the passes take longer. On a two-car driveway or a fence line, that gap stops being a number on a spec sheet and starts being an extra hour of your Saturday.
My honest read: this is a good second washer for someone who already has a gas machine for the heavy work, or a first washer for someone with a small patio and a short list. If your plan is a full driveway every spring, spend the difference and get the flow.
Kärcher K5 Power Control: the hose argument
The K5 Power Control is rated 2500 max PSI and 1.55 max GPM, and it comes with a 32 ft hose and two spray wands. That hose length is the most underrated spec in this entire comparison. A 32 ft hose means you park the machine once and walk the work, instead of dragging the unit around the driveway every few minutes or fighting a short hose that kinks at the worst possible moment. Anyone who has spent an afternoon repositioning a washer to reach the back of a car knows exactly what that is worth.
The two wands matter too. Having a second wand set up means you are not swapping nozzles with wet hands mid-job, and it gives you a spare if one gets dropped on concrete. At 2500 max PSI this is also the highest pressure figure of the four, which makes it the best choice for concrete and for stripping a fence, as long as you respect what that pressure does to softer surfaces.
The trade-offs are real. It is the most expensive of the four, its 1.55 GPM flow still trails both Westinghouse units, and the brand's accessories tend to cost more than generic equivalents. You are paying for the hose, the wands, and the reputation for durability, not for the highest flow in the group.
The trade-offs that decide it
Flow versus pressure. If you want the fastest cleaning, buy flow. The two Westinghouse units at 1.76 GPM will cover more square feet per minute than the Kärcher at 1.55 GPM and considerably more than the CRAFTSMAN at 1.2 GPM. If you want the most aggressive single pass on concrete, buy pressure, and that points at the Kärcher.
Detergent draw. The ePX3100s gives you a foam cannon, the ePX3100 gives you an onboard soap tank, and the Kärcher uses its own detergent system. The CRAFTSMAN, with no soap system listed, is the one that leaves you doing the soap step by hand.
Hose and wand quality. The Kärcher wins this on paper with 32 ft of hose and two wands. The ePX3100 counters with a steel wand and five nozzles. The ePX3100s gives you the foam cannon and turbo nozzle instead. The CRAFTSMAN is the light, compact option, which is a feature until the hose is too short for the job.
Footprint and stability. Anti-tipping technology on the ePX3100 is a genuine safety feature on a sloped driveway. A lightweight compact unit is easier to store and easier to knock over.
Which one for which job
- Cars, boats, and anything with paint: the Westinghouse ePX3100s. The foam cannon is the whole argument, and 1.76 GPM rinses fast.
- Driveways, fences, and siding: the Westinghouse ePX3100. More pressure, more nozzles, onboard soap, and the same strong flow.
- Concrete and heavy stripping, plus the longest reach: the Kärcher K5 Power Control. 2500 max PSI and 32 ft of hose.
- Patio furniture, a grill, a small walkway, and easy storage: the CRAFTSMAN CMEPW1700, as long as you accept the slower pace.
- One machine for everything a normal homeowner does: the ePX3100s, then add a surface cleaner attachment when the driveway starts bothering you.
The short version
If you want one answer, it is the Westinghouse ePX3100s, because 1.76 GPM of flow plus a foam cannon and a turbo nozzle covers car work, concrete, and everything between without a second shopping trip. If pressure and nozzle count matter more to you than detailing accessories, the ePX3100 is the stronger machine. If hose length and a durability reputation are worth a premium to you, the Kärcher K5 Power Control earns it. And if your list is short and your storage is tight, the CRAFTSMAN CMEPW1700 will do the job, just slower.
Check the flow rate before you check the pressure. Every time I have been disappointed by a pressure washer, that is the number I ignored.
