This Pressure Washer Means Business (And It’s Under $400!)

If you’ve got dirt, stains, or a driveway that looks way past help, you’ll want a serious outdoor cleaning machine. The Simpson 3400 PSI gas pressure washer packs the punch to blast away years of grime fast. With a powerful 3400 PSI rating and a flow of 2.5 GPM, this unit makes cleaning large outdoor surfaces much easier.

It’s more than just strong water pressure. It’s built for real work. From weathered decks to stained garage floors, this washer handles tough spots like a pro. The price? Starts at just $379, depending on the model. That’s serious value for a high pressure gas washer that performs like the big guys.

Here’s why it might be your next favorite tool.

Let’s start with performance. With 8,500 cleaning units (PSI × GPM), this washer removes thick grime, old stains, and tough buildup across large areas. It covers up to 1,800 square feet per hour. That’s a huge jump from regular residential power washer models.

The CRX engine pressure washer version comes at a lower price and still gives reliable power. For bigger jobs, the models with the Honda GX200 or Kohler SH270 engines kick things up a notch. They're known for starting easily and lasting longer under heavy use.

You also get a 25-foot MorFlex hose. It’s flexible, kink-resistant, and doesn’t leave marks. That means fewer interruptions and smoother handling while you clean patios, siding, or concrete.

This pressure washer handles everything from cars and fences to mildew-covered bricks and oil-stained driveways. Need something tougher? The ALH3228-S version uses a CAT Triplex pump and a Honda engine. It’s built for contractors or anyone who cleans often.

Even if you’re not a pro, the mid-range MS61084-S with the Kohler SH270 engine hits the sweet spot. It’s $379 and packs more than enough power for home use. It also holds up better over time than a basic electric or lower-end gas unit.

Every model comes with quick-connect nozzles for different spray angles. From laser-sharp to wide spray patterns, you get control over how hard you hit each surface.

If you're a homeowner, you’ll like that this machine is easy to move. It’s got 10-inch pneumatic tires that roll smoothly over uneven paths. The steel frame feels solid and can handle the vibrations of a gas engine.

Storage is simple too. The handle folds down, and there are built-in holders for the gun, nozzles, and hose. No more tangled cords or scattered parts in your garage.

For most yards and driveways, the 3400 PSI models are more than enough. They help restore surfaces without calling in a pro. Think moldy patio furniture, green siding, dirty sidewalks—you name it.

• Honda GX200: Quiet and reliable. It’s the premium pick for regular use.
• Kohler SH270: Easy to start in cold weather and powerful enough for most tasks.
• CRX 210: A budget-friendly option that still meets the 3400 PSI mark.

Each engine uses a simple pull-start system. On a full tank, you can run for 1.5 to 2 hours. That’s enough to get most weekend projects done without needing a refill.

• Simpson ALH3228-S – $772.50: Pro-level with a CAT pump and Honda engine.
• Simpson MS61084-S – $379.00: A great middle-ground with strong power and durability.
• Simpson CM61083 – $379.99: A budget choice with the CRX engine.

All three models meet the same power level, but the pump and engine quality affect price and longevity. The ALH3228-S will last the longest if you clean often. For weekend driveway work or occasional deck cleaning, the MS61084-S gets the job done without stretching your budget.

• Siphon Tube: Lets you pull detergent from any container—no mixing needed.
• Thermal Relief Valve: Keeps the pump safe from overheating.
• Axial Cam Pump: Great for homeowners, and it requires no maintenance.
• CAT Pump (on select models): Built for long life and higher cleaning hours.

You’ll also find the build compact for the power it holds. Many models measure around 34" by 21" by 24", making them easy to tuck away when not in use.

Homeowners love how it revives outdoor surfaces without using harsh chemicals. Many say it’s easy to use, even for beginners. They also like how fast it works compared to older or weaker units.

Contractors mention long-term reliability. The weight is heavier than small units, but the results are worth it. Several users say they’ve used the same model for years with just basic upkeep.

The Simpson 3400 PSI gas pressure washer brings strong performance for both everyday cleaning and heavy-duty jobs. It’s built to last, easy to maintain, and has models that fit different budgets and needs.

Want the longest life and best power? Go with the ALH3228-S. Need a great washer without spending over $400? The MS61084-S is a smart pick.
