The WEN PW3100 is a machine that gives you all the power you’ll need to pressure wash your house, patio furniture, or other household items in the way it’s meant to be done. If this is the kind of performance you need, you might expect to pay hundreds of dollars more than what this unit costs. But you won’t have to, because the manufacturers of this machine have engineered an inexpensive tool with the kind of power you usually only see in higher-end models.

WEN PW3100 Gas Pressure Washer

To get the job done, you really need the power of a 3,000+ PSI machine. Unfortunately, most electric power washers are too small for most situations. And, many quality gas pressure washers aren’t exactly affordable. With 3100 pounds of pressure at your fingertips, the WEN PW3100 will blast away dirt, grime, and caked-on mud like few other machines on the market.

And if you’re wondering about the CU score, it’s 7750, which isn’t too shabby. It’s such a fantastic unit, it even earned a spot on our top 6 best gas pressure washers of 2020.

What do you get with a WEN PW 3100

Features of the PW3100 power washer.

  • 208cc air-cooled 4-stroke PHV engine
  • 2-year warranty
  • five quick-connect nozzles: 0°, 15°, 25°, 40°, and soap
  • Nozzle storage holder
  • Nozzle usage chart
  • 30-foot reinforced hose
  • Onboard soap tank
  • Quick connect spray gun
  • Axial cam pump
  • 12-inch never-flat wheels

It has an Axial cam pump instead of a Triplex. So, if you have the unit any length of time, you’re probably going to have to replace the pump. This machine has a soap dispenser that loads from the front and holds about eight ounces of fluid.

The heavy-duty pre-installed wheels are 12 inches in diameter, which allows you to tackle a wide variety of tough terrains. And, they’ll never go flat on you since they’re not pneumatic.

Product Dimensions

  • Weight: 75 pounds
  • Height: 40 inches
  • Length: 21 inches
  • Width: 21 inches


This pressure washer pumps an impressive 2.5 gallons per minute. This is enough water flow to tackle virtually any household task you need to get done. You’ll go through a tank of gas every two hours or so. The engine is super easy to start. And, it’s quiet, so doing a job won’t turn into an assault on your poor neighbors’ ears.

Man attaching the nozzle.

This unit doesn’t have adjustable pressure control on the wand. That means to change the pressure, you’re going to have to change the nozzle. But fortunately, the nozzles change without too much difficulty. All that’s required is to slide back the collar at the end of the lance and pop in any one of the five included attachments. There’s even an onboard compartment with slots for all five nozzles.

The 30-foot hose is excellent because it gives you far more range of reach than most other pressure washers. Lots of them have hoses that are only 25 feet in length. It has bigger wheels than some other models, so it’s not too difficult to lug across the yard. And because the tires aren’t pneumatic, you’ll never have to worry about a tire going flat again.

What’s to love about the WEN PW3100


After adding your oil and gas, it’ll start on the first pull. It’s a 4 cycle engine, so no mixing of oil or fuel is required.

It puts out one heck of a water blast, so you should have plenty of aqueous force at your command. The assembly is quick. For most people, it will only take 30 minutes or less. You get a handy chart nozzle that’ll let you know which each nozzle is for. That way, you don’t have to guess.

The cutting path is three to four-inch-wide, which is pretty decent.

What’s not so great about the WEN PW3100


Some people report that when you wheel it around, the cotter pins used to hold the wheels in place can punch a hole in the soap tank. An easy fix for this is to put the cotter pins on the outside of the wheels.

When you first use it, the hose might feel a little too rigid. However, over time it becomes more supple. It also kinks up a little too easily, which can be a bit of a pain. Some report that engine vibration pops the tips of the nozzle attachments right out of their holder. So, you might want to think about keeping the nozzles in your toolbox where you won’t lose them.

Some users report that when the box was shipped to them, it didn’t include oil. So, you might want to buy 10W30 oil before your package arrives at your house—so you’ll be ready to use it immediately.

After all, that grimy lawn furniture probably has waited months for a bath. And it can’t wait another day!

Helpful Tips

PW3100 has a detergent tank but you might never have to use it.

This pressure washer has a detergent tank, but with this much power, you might never have to use it. However, if you’re tackling an especially tough job and you need to boost your cleaning power, add your favorite detergent to the onboard tank. This will help break down grime, dirt, and other surface buildups before the stream of water even hits it.

Make sure you use the soap nozzle when using detergent. Also, you’ve got to be very careful with the 0° degree setting. That’s because it’s so powerful it not only takes off paint but can cut into your precious stone and tile too.

Unlike some other pressure washers you can buy, the wand feels very comfortable to hold. You’ll be grateful for this ease of handling when you have a job that’s going to take hours to finish. However, be extremely careful when attaching the various nozzles. If you don’t attach them securely, they’ll fly off, and you’ll be hunting for them for days.

Final Thoughts

In spring, in some areas of the country, your patio furniture can get covered by a thick layer of yellow pollen from oak trees. If you live where this happens, you’ll love the WEN PW3100, because it’s perfect for this type of job.

After 3-4 uses in 36 months after purchase the water pump is leaking and pressure drops so it’s useless. Is this common because I read that the Axial pumps don’t hold up after a couple years but this machine was a gift and I’m not satisfied with the performance
