  1. SIMPSON ALH4240 Aluminum Gas Pressure Washer

Our topmost pick is the SIMPSON Cleaning ALH4240 unit, one of the best options for busy professionals with a low budget. The model has been creating a buzz with its strong jets of water, which can reach a maximum pressure limit of 4,200 PSI. That said, let’s check out whether it’s worth your attention.

Why Did We Like It?

Straight off the bat, the brand hasn’t left any stone unturned to pack this model with superb performance. And the prime example is its Honda GX390 engine that has left most of the users utterly satisfied with the fuel efficiency it offers. Compared to other gas-powered washers, you get longer run times amidst fuel refills with the ALH4240. That said, this model appears pretty efficient for busy handymen and construction workers with a limited budget.

Apart from that, the product also ranks very high in terms of durability, and the credits go to its sturdy aluminum frame. The build material is certified as aircraft-standard, which means that it’s built to last for years. Despite such strong tubing, it comes off to be extremely lightweight for a mid-range pressure washer. Maneuverability is further enhanced by its 13-inch pneumatic wheels, making transportation a cakewalk for the users.

We’re fans of how efficient this model is at what it does, as you can max the pressure limit up to 4,200 PSI to perform your jobs with maximum power. Not to forget, cleaning has been more comfortable with the 50 ft hose that allows you to deliver fierce jets of water in some very hard-to-reach areas.

What Could’ve Been Better?

Although this product is a complete steal of a deal for professionals and commercial users, it might be too much for personal use. Also, it’d have been a little better if the manufacturers focused on lowering its noise levels, as the model is deafeningly loud.

Pros
  • Superb pressure at 4,200 PSI
  • 50 ft hose for efficient cleaning
  • Sturdy build material
  • 5 detachable water spray nozzles
Cons
  • High noise levels
  1. Pressure PRO e4040hc Heavy-Duty Professional 4,000 PSI Pressure Washer

Moving on to some more commercial-grade alternatives on our list, the Pressure PRO 4,000 PSI pressure washer is probably the only worthy competitor of our first pick. Although we’re in love with how much the manufacturers have focused on longevity while designing this model, it’s much more than just a durable tool. Let’s find out more.

Why Did We Like It?

First and foremost, this product also features a robust Honda GX390 engine, which speaks volumes about its reliability. Fortunately, it is a little quieter than our previous pick, which makes using it a little more comfortable. Also, it beats any other product in terms of safety, all thanks to its advanced thermos-sensory feature. This sensor eliminates the chances of overheating issues, which further saves the motor from any catastrophic damage.

We’re fans of its CAT Brand Triplex Plunger Pump that helps the machine run cooler, extending the product life even further. It comes in a premium aircraft-grade frame that safeguards the engine from any unprecedented damage. And although it’s motor isn’t as fuel-efficient as the SIMPSON cleaning unit, it compensates for that with its low-oil shutdown feature. This way, it prevents any discrepancies while it’s running low on fuel.

Although it isn’t the most lightweight pressure washer we’ve tested, it doesn’t come off to be very hard to maneuver either. Its ergonomic handle and large air-filled tires make it very easy to transport anywhere. Last but not least, this model can also crank up to 4,200 PSI at its highest setting, making it eligible for hardcore commercial jobs.

What Could’ve Been Better?

Like our previous pick, this one also appears to be overkill for small-duty personal/residential jobs. The product also seems to be unbelievably expensive, but it hardly brings something new that isn’t already available in the SIMPSON pressure washer.

Pros
  • Durable build material
  • Maximum pressure output of 4,200 PSI
  • Large air-filled tires for easy transportation
  • High-pressure spray nozzles
Cons

Next on our list is Briggs & Stratton, a pioneer in the maintenance tools market. The ELITE4000 lives up to its name, as its maximum pressure output of 4000 PSI spells nothing but majestic power. For those looking for a budget-friendly commercial pressure washer, its 4.0 GPM capacity is a fair dealmaker.

Why Did We Like It?

The product had initially caught our attention with its bargain-basement price, but it easily outperforms some of the most expensive tools in the game as of now. For starters, it features a very sturdy 2100 OHV motor that delivers a maximum pressure output of 4000 PSI. And although it isn’t as powerful as the Honda GX390, it’s comparatively more compact and lightweight, which is a significant advantage for DIY home maintenance/improvement jobs.

Furthermore, we’ve found its build material to be quite robust, ensuring a long-lasting product life. It also comes with a set of pneumatic wheels for easy transportation, making it appropriate for busy cleaning/maintenance professionals. Not to forget, you also get an Annovi Reverberi Triplex Pump that enables you to control the pressure accordingly with its regulator. The model further offers 5 quick-connect spray nozzles that enhance its versatility by a fair deal.

Like our first pick, this one also features an extensive 50 ft long hose for in-depth cleaning. The tube has been tested to withstand higher water pressure and rigorous usage, which is a plus for both medium-duty and small-duty jobs.

What Could’ve Been Better?

Being a low-budget option, this product doesn’t stand out to be as powerful as our previous recommendations. Furthermore, we’re a little disappointed that it doesn’t come with ample features to make it more fuel-efficient.

Pros
  • Built to last longer
  • Powerful OHV engine
  • 4.0 GPM capacity
  • Very affordably priced
Cons
  • Not very fuel-efficient
  1. Generac 6565 4.0 GPM 420cc OHV Gas-Powered Commercial Pressure Washer

Generac has established a name for itself in the maintenance tools market with its top-notch innovations for commercial use. At a slightly higher price, the Generac 4.0 GPM pressure washer is an upgraded alternative to the Briggs & Stratton unit. That said, let’s check out its core specs and functions.

This product comes equipped with a professional-level Triplex pump, which stands out to be 4 times more durable than the axial cam pumps. Moreover, it also comes equipped with a strong OHV motor that offers a streaming capacity of 4.0 GPM, which is quite incredible for a mid-range pressure washer.

Furthermore, the 420cc OHV motor can exert a maximum pressure of 4,200 PSI that makes it eligible for heavy-duty cleaning. We’re also impressed with its excellent and robust frame, enabling the product to last longer than the usual alternatives in the market. Moreover, it also comes equipped with a low-oil shutdown sensor that prevents the motor from severe damage when it runs low on oil.

You also get a set of pneumatic wheels and an ergonomically designed body that raises the bar quite high for portability. The product doesn’t appear to be very heavy, making it easier to maneuver. Last but not least, it comes with an extended 3-year warranty period.

What Could’ve Been Better?

Quite frankly, the product isn’t bad for a mid-range pressure washer. However, it has a frequent tendency to vibrate while being used, and we’re hoping that the manufacturers would take the necessary steps to eliminate this issue.

Pros
  • Superb pressure of 4,200 PSI
  • 50 ft hose for efficient cleaning
  • Sturdy build material
  • 3-year warranty period
Cons
  • Frequent vibrations

Despite being a piece of medium-duty personal equipment, this product still packs serious power under its compact frame. For starters, we were quite surprised by what’s under the hood, as it offers a durable and long-lasting Honda GX 390 engine. Moreover, it appears to be twice as fuel-efficient as a standard tool in this category, which gives us another reason to appreciate its brilliant engineering.

At first glance, the raw naked appearance of this device might have you questioning its longevity, but the welded body is surprisingly very strong. We’re fans of its 15-inch pneumatic wheels and bent easy-grip handle that help move it around with ease. Moreover, you also get a world-class CAT pump that delivers up to 3.5 GPM capacity. It is coated with top-notch ceramic plungers, which makes it resistant to corrosion and abrasion.

That said, this product can reach as high as 4,000 PSI at its highest setting, which makes it entirely appropriate for home maintenance jobs and similar light-duty jobs. We are also impressed with the user comfort it offers, as it comes with an Easy Start option for smoother and more comfortable recoil pulling.

What Could’ve Been Better?

First and foremost, we didn’t find its unloader valve connection reliable at all, which makes us question its durability as a whole. Furthermore, it’d have been a little more comforting if the product weren’t so loud.

Pros
  • Built to last longer
  • Powerful engine for high pressure
  • 4.0 GPM capacity
  • Very easy to maneuver
Cons
  • Unloader valve connection can’t be relied upon

You also can control the pressure as per your requirements, enabling 100% user control while working. In case you’re washing areas that aren’t possible to reach easily, its 50 ft hose length will definitely come in handy.

We were also impressed by its 4 ft detergent hose, which significantly enhances the device’s versatility. Its fuel tank has a capacity of 1.6 gallons, and also offers impressive fuel efficiency as a bonus. Consequently, the motor is capable of running for hours without asking for a refill. We noticed a sensor that shuts down the machine at low fuel, which works well to prevent any damage.

What Could’ve Been Better?

There weren’t any performance issues that we observed in this model, which makes it a suitable all-rounder. However, its price is a little too high, so that’s an issue that may stop some from buying it. Moreover, we believe that it should come with a longer warranty period.

What Could’ve Been Better?

What Could’ve Been Better?

4000+ PSI Pressure Washer Buyer’s Guide  

Here are the following factors that you must consider before buying a 4000+ PSI pressure washer. Making sure that you cross-check these features before buying can lead to a brilliant purchase.

  1. Horsepower

First and foremost, the most important criterion determining the efficiency of such a powerful machine is its horsepower. It has a direct relation with the GPM and PSI of the device, and that’s why you shouldn’t settle for anything less than 15 HP.

  1. Cleaning Techniques

Many pressure washers feature a standard detergent injection technique, a system that simplifies cleaning through automated siphoning and detergent-mixing. On the other hand, various models also come with onboard tanks that store detergent. At a slightly higher cost, the detergent injection techniques make your job easier.

  1. Nozzles

Last but not least, the vents contribute a lot to enhancing the device’s overall efficiency. These adjustable nozzles come very handily at handling different jobs, as you can easily change its pattern for versatile applications.
