Another feature that can be attributed to its powerful performance is the GX390 engine, which delivers 13 HP of power. The pump is also designed in such a way that it will perform great while being able to demonstrate exceptional durability.
Still, with regards to its durability, it is good to know that it is incorporated into a frame that is made from aircraft-grade aluminum. To add, the manufacturer is offering a lifetime warranty on its frame, which is again another indication of its impressive quality.

- No pressure gauge
Simpson Cleaning PS4033 Gas Pressure Washer Powered by Honda
With only 3.3 GPM, this is one of the models mentioned in this post with the lowest flow rate. Nonetheless, this does not mean that its performance will be inferior. Thanks to its Honda GX270 engine, it is built to perform.
Another thing that makes the engine great is the low oil alert, which will minimize frustrations when using the pressure washer. You will be immediately notified when there is a need to change oil so that you can work continuously and to prevent damage to its components.
The triplex plunger pump is one feature that is worth highlighting in this model. It is an industrial-grade pump that can last through the years. More so, it comes with the revolutionary Power Boost technology, which increases its pressure.

Commercial Pressure Washer: Generac 6565 4200 PSI 4.0 GPM
If you want a pressure washer to be powerful, you should pick one that is powered by gas. They can be louder in terms of the noise that they create, but they can perform better even in the most demanding tasks. One of the reasons why this is powerful is because of its 4 GPM flow rate.
In terms of its motor, the unit is powered by a Generac 420cc OHV engine. This extra-powerful engine makes it a beast while exerting all the effort. With this engine, it does all the work and hence, fatigue can be minimized with its use.
Similar to its engine, the pump is also designed to be long-lasting. The pistons are ceramic-coated to deliver long-term functionality.
The design of the spray gun is also worth noting since it is comfortable and user-friendly. The nozzles are easy to change, depending on the intended application. The trigger is also easy to pull. Plus, the grip is designed with a cushion for your comfort.

Pressure Washer With Cat Pump: Simpson Cleaning PS4240H 4200 PSI at 4 GPM
This is almost similar to the model from Simpson Cleaning that has been mentioned earlier in this post, with the most significant difference being its engine. Rather than Honda, the engine is from Kohler, which is equally powerful.
The CAT Industrial Triplex Pump is also a great add-on to this model. The head is made from forged brass, which can withstand even high pressure. There is also a thermal relief system, which effectively provides protection from high temperature, among other things.
Meanwhile, its chassis is made from 100% aluminum. For this reason, it is lighter than those that are made from steel. It can also resist corrosion and oxidation.
You will also love the steel-braided hose, which is durable. It is non-marring. To add, it is resistant to abrasions.
- Has an on-board accessory storage

Briggs & Stratton 20507 Elite Series Pressure Washer
This model has a flow rate of 4 GPM, which is quite common in most of the 4000 PSI pressure washers. Its power is derived from its OHV 420CC engine. It can deliver 21-foot-pounds of gross torque, which is one more thing indicative of the fact that it can indeed deliver powerful performance.
One of the notable features that you can find in this product is the detergent injection system. The water and the cleaning solution will be mixed in an instant, which will make cleaning quicker and easier.
To add, it also has 12-inch never flat wheels. You do not have to worry that it will deflate or that it will have holes from hitting sharp edges on the ground. Like the machine itself, the wheels are built to withstand the test of time.
There are also built-in accessory compartments. This will make it easy to keep your things organized and will provide you with easy access to the accessory that you will need to complete a task.
This 4000 PSI pressure washer comes with a 2-year warranty from the manufacturer.

The product also comes with a user-friendly pressure control system, which is also one of its most notable features. With remote pressure control, it will be easy to adjust the pressure by just tapping the right wand.

More so, it has an upright design and a compact body. Even in tight spaces, it will be easy to move the pressure washer. This also means that it will not require too much space in the storage room.
However, there are some people who reiterated that the quality of the accessories could have been better. If this is your problem, you can easily buy replacement accessories. After all, their price is quite easy in the wallet.

- Has plenty of pressure for a wide array of tasks
- Accessories could have better quality

Amazing Machinery 4000 PSI Pressure Washer
This 4000 PSI pressure washer delivers a water flow rate of 4 GPM. It is powered by a Honda GX390 motor. Even experts would surely agree that Honda is a name that is hard to rival when it comes to quality and performance.
It is also a good thing that this model is ready to operate out of the box. Simply put, this means that you do not need to exert effort in its assembly. Once it is taken out of the box, the unit is ready to be used.
The 50-foot high-pressure hose is also a plus for this unit. You do not need to be near the product all the time. You will have the freedom to move because of the generous length of the hose. It is even made better by the fact that it has color-coded nozzles, including one that is specially designed for the application of chemicals.
For the frame and wheels, the manufacturer is offering a one-year warranty. For the other parts, meanwhile, the warranty is only three months.
- High-quality and durable frame

Be Pressure PE4013HWPACOMZ Pressure Washer
The price of this model is ridiculously high, making it one of the most expensive of the products that have been mentioned in this post. For professionals, this can be a good choice, except for the fact that it does not fare well in terms of its popularity.
As we all know, the engine is the one that will be indicative of the performance of a pressure washer. With this model, you will be happy knowing that it has a 389cc GX390 Honda engine. It is gas-powered, which makes it even more superior when talking about performance.
To add, the pressure washer is also designed with a steel braided high-pressure hose with a length of 50 feet. It has an extensive reach and is also excellent when it comes to durability. Even with frequent and long-term use, you can expect that the hose will retain its functionality.
The 10-inch pneumatic tires, on the other hand, provide you with the assurance that moving it will be easy. With an aluminum frame, it is not as heavy as the others, and hence, fatigue can be minimized. Lastly, it also comes with rubber foot that can resist vibration.
- Versatile cleaning applications
- Has a Honda engine
- Large tires
- Not as popular as the other models
- Expensive price
North Star 15781520 Pressure Washer
Gas-powered pressure washers often have a negative reputation because of the noise that they make when they are operating. Surprisingly, in the case of this model, it is quiet even as it works and delivers powerful cleaning. This is despite that it comes with a Honda GX390cc engine.
Another good thing about this model is that it has a horizontal shaft design. This is better than the vertical shaft and increases its durability by as much as five times.
The Comet pump that is incorporated in the unit is also worth pointing out. It has forged brass manifold, which is also contributory to its longevity. For protection, there is an included thermal protector, which protects the internal components of the unit.
With a push-down style cart, you can also expect that it will be easy to use. It might look heavy at first, but when pushed, you will be surprised at how user-friendly it is. Aside from the design of the tank, this is possible because of the excellent construction of the tires.
- Operates quietly despite being gas-powered
- Has a direct drive motor
- Equipped with several safety features
- Can be difficult to crank
- Not fully-assembled

I’m trying to figure out how much pressure washer I really need for the jobs I’d like to do. I want to do common things clean the bricks on the house up a bit, clean the cars on occasion, etc. but I would really like to use it to help clean and strip an approximately 400-500sqft deck. After cleaning (with just a hose, stiff bristle shop broom) and re-staining it two years ago it looks pretty rough. It does get a lot of sun, and I feel like there is great guidance on picking stains, there’s not quite enough on pressure washers.
The discussion seems to center on electric vs gas, but there seems to be some cross over in PSI for some of them, even though the flow is higher on the gas powered. My question boils down to this: if I invest in a reasonable electric pressure washer (1400-1800psi or so) and get a reasonably narrow nozzle, would it be effective enough to strip a deck?
We also have a concrete driveway and some sidewalks it would be nice to clean up probably a total of triple the area of the deck but from the sounds of it, an electric would never be able to clean those adequately in less than a day.
Based on what I’ve learned and that as much as I would like to do this I can’t afford a 3200psi small arms grade water laser that would do anything I could ever need it to for most of my life. I also don’t truly have the time and other equipment to make upkeep reasonable. I think for me, a high quality adjustable nozzle (or multi-head) electric will be fine with the understanding that some things will take significantly longer than with a high powered gas version.

I use a 3600 PSI Pressure Washer with a 15 degree nozzle/tip on all of my personal vehicles including two that have expensive custom paint jobs.
If your car’s paint in intact it is not going to harm the paint at all as long as you use a 5 degree of better tip on the gun.
If would not try the 0 degree tip at any pressure.
0 degrees is the one thin stream of water, when the water is not fanning out at all.
Also watch out for vinyl graphics, pin stripes, dealer stickers, as it will remove them, but will not harm a normal paint job in good condition.
Stand back from the car a few feet and spray away.
Most pressure washers, up to 1800 psi are made specifically for cars.
What I use is indeed excessive, but only mentioned to prove to you that it will not harm the paint.
So,
1.) Make sure the water coming out of the gun has a fan to it and not just one straight stream.
2.) Stay clear of vinyl graphics, pin stripes and dealer stickers unless you are back at least 6 feet.
3.) If this is the first time that you are using a pressure washer on a vehicle, I would make sure it is no more than 1800 psi until you get used to it.
4.) Do not hold the tip of the gun right up to the paint … stand back a few feet.
Do that and you will be fine.
Patrick says
I have a 4000 psi Honda pressure washer that I can regulate the pressure down to 200 psi and up to 4000 if need be.you won’t need all that pressure to do a car,maybe wheel barrels or floor mat blasting, pressure washing houses and decks etc..

How to operate a craftsman 2550 psi pressure washer?
Angela Nikolson says
I’m leaning on a 4 GPM/4000 PSI Pressure Washer.
Can anyone just give me a rough guideline on operating PSI on the following materials
Concrete Driveway – 3.500 PSI
Stonework – ???
Brick – brick is a soft material ???
Aluminum Siding—Window Exterior – 1200 to 1500 PSI
Wood Decking – 1200 to 1500PSI
Paint *Car washing* – 800 to 1000 PSI ?
So confused on how to adjust the PSI.
Some of recommended to use the unloader.
Others have said, let the machine run at full tilt and just buy upsized nozzles.
What’t the consensus. Do I just buy a pressure gauge and put it on the out and use the unloader or upsized #6, #8, #10 nozzles.
Roland says
I bought a cheap under $100 Greenworks 1500PSI electric pressure washer from amazon 8 months ago. I used it to clean our lanai, which had not been cleaned for over 4 years – it was filthy! Encrusted with black mold and massive amounts of dirt. This was the cheapest solution I could find – and it worked like a charm. It was a slow process, the relatively low pressure was strong enough to clean the painted concrete thoroughly, but only a 1-2″ swath at a time — it took me 1 hour per day for 8 days to get the job done — but it worked perfectly.
It may not be BIFL, but I don’t think any pressure washer is going to be “for life”. I’ve had a $400 gas powered pressure washer in the more distant past, and just starting the engine was a continual struggle — this one was so easy to use, it was pleasant! And it was so cheap, it would have cost me >>$100 to hire somebody to do the job for me, so after finishing the job, I’m already “ahead” financially.
I bought this model after looking at the customer reviews – it got very good reviews there, and my experience was similar. Maybe, in this case, don’t BIFL, but go cheap?
Bobby says
Hot electric water pressures vs. Cold electric water pressures
Which is better for what duty? Is hot or cold better for vehicles, side walks, vinyl siding, windows, brick buildings/houses, wood, removing paint/stains, etc. And also- what is a good PSI for these sort of things? Thinking between 2000 and 4000psi? What is best..?
Jasper says
