Best Gas Power Washers Detailed Reviews

SIMPSON Cleaning PS3228 PowerShot Gas Pressure Washer Powered by Honda GX200, 3300 PSI at 2.5 GPM, Black

1. SIMPSON Cleaning PS3228 PowerShot Gasoline Power Washer

This pressure washer provides a highly powered flow that will handle most jobs. The 3300 PSI is incredibly powerful and it is backed by a 2.5 GPM. I like the fact it comes with 5 nozzles (0, 15, 25, 40 degree & soap) and its large tires make it easy to move around.

There is a 25 foot hose so you can move quite a distance away from the motor and move into harder to reach places. The pressure washer has a 16-inch steel ergonomic spray wand and features a trigger lock so it will stay off when you are not using it. The pneumatic tires absorb the vibration too.

I think one downside is that this model isn’t the cheapest available and might be out of the price range of some people. You will also need hearing protection as it is louder than other washers on this list. The handle is quite low so if you are using this a lot it can be hard to move and it weighs 84 pounds but is fine for personal use. This is an industrial level power washer that comes with a AAA Industrial triplex plunger pump combined with PowerBoost Technology for a powerful experience.

Pros

  • Heavy duty pressure washer that will clean most surfaces well.
  • 25 foot hose is great for moving around.
  • Features AAA Industrial triplex plunger pump with PowerBoost Technology.

Cons

  • Very loud so you will need hearing protection.
  • Might be out of the budget for some people.

Sale Champion 3200-PSI 2.4-GPM Dolly-Style Gas Pressure Washer

2. Champion Dolly-Style - Best Power Washers For Home Use

This model is quite similar to the previous one on our list but has a slightly lower PSI and 3200 backed by a 2.4 GPM. There are 5 nozzles (0, 15, 25, 40, and soap) and a 25 foot hose.

I think that the durable frame that is made of steel is a great feature to ensure that this pressure washer lasts. There is a low-oil shutoff sensor as well as 12 inch wheels which makes moving around fairly easy. The heat shield can become very warm when in use and the instruction manual isn’t the clearest especially if you are new to gas pressure washers.

It’ll do a range of jobs for you and only has a few features that can be considered drawbacks.

Pros

  • Durable steel frame so this should last with heavy duty pressure washing.
  • Very powerful with 3200 PSI and 2.4 GPM.
  • Low oil shut off sensor.

Cons

  • Instructions aren’t clear especially for new users.
  • Heat shield can get very hot.

Duromax XP3100PWT 2.5 GPM Gas Powered Cold Water Power Pressure Washer, 3100 PSI

3. Duromax XP3100PWT - Best Gas Powered Pressure Washer

This model is one of my favourites and it provides a powerful spray with a 3100 PSI and 2.5 GPM. It will get rid of tough grime and dirt and six nozzles (0, 15, 25, 40, soap & rotary/turbo) and it also offers a detergent tank that is built in.

It is quite light too at only 75 pounds and the hose extends to a length of 25 feet. The hose and wand retainers aren’t the most durable and they are held in place by a plastic attachment. It does need a bit more maintenance than other models as the air filter will have to be cleaned after 50 hours of usage.

I think this is one of the best models on the market. Although it needs extra cleaning and maintenance it does offer a powerful clean with good maneuverability.

Pros

  • Will produce good results with 3100 PSI and 2.5 GPM.
  • Six nozzles and built in detergent tank.
  • Lightweight with 12” oversized never-flat wheels.

Cons

  • Does require some maintenance.

Sale WEN PW3100 Gas-Powered 3100 PSI 208cc Pressure Washer, CARB Compliant

4. WEN PW3100 Heavy Duty 3100 PSI Gas Pressure Washer

The next gas pressure washer is a bit more powerful than the first. With 3100 PSI it will clean up dirt and grim in most situations. It weighs only 67 pounds so it is a bit heavier but still very light if you need to carry or wheel it around. I think this is a great model for residential use as it will clean up driveways, patios and is a budget-friendly way to have a powerful washer.

It has several nozzles (0, 15, 25, 40 degrees) that are easy to change. I think its vibration can be off-putting at times as it can be distracting and this adds to the noise level. It is still fairly quiet for a gas pressure washer. It will generate a powerful flow that will lift dirt and grim in most cases.

The wheels can be a bit shaky so moving it over long distances might be tricky. The choke is also manual so you need to set this up before you start. I think for people who have never used a gas pressure washer before this can be challenging. Overall it is a powerful pressure washer that will do the job for most people in a residential setting.

Pros

  • It provides a powerful flow at 3100 PSI.
  • Comes with several easy to change nozzles (0, 15, 25, 40 degrees).
  • Easy to set up and is quite quiet.

Cons

  • Manual choke which can be difficult for some people.
  • Level of vibration is high.

Generac 6922 2,800 PSI, 2.4 GPM, Gas Powered Pressure Washer

5. Generac 6922 2,800 PSI, 2.4 GPM, Smallest Gas Pressure Washer

The first gas-powered pressure washer on the list offers a range of features and is ideal for residential use. This power washer is very lightweight at only 57 pounds which makes it very easy to move around. The 2,800 PSI means that it packs a power punch and this is supplemented by 2.4 GPM. This isn’t the most powerful power washer that you will find but it is ideal for tackling dirt on driveways, patios and the outside of your home.

I think the 25 foot pressure hose and the 4 nozzle tips are great. It means you can move quite a distance from the pressure washer itself without having to move it around. There is a comfortable grip on the handle for easy movement.

This is for cold water pressure washing and it doesn’t offer a function for hot water pressure cleaning. The pressure washer doesn’t have a pressure output regulator. It is designed for low to medium jobs. It won’t strip the paint of your home very well but it will clean your driveway to a high standard. I think the noise level is OK. It isn’t silent but it won’t be heard down the street either.

Pros

  • It has a mobile design with durable frame.
  • This gas pressure washer comes with 4 nozzles.
  • Long hose so you don’t have to move the whole device.
  • System to shut off fuel delivery and the choke.

Cons

  • Not the most powerful model.
  • No pressure output regulator.

How Were The Best Chosen?

Reliable And Durable

A gas pressure washer should work when you want it to and also last for a long time. The unit that you buy should be able to withstand heavy usage. With pressure washing you will find many objects bouncing off the surface you are washing so it is important that it is able to tolerate this.

Even though the gas units do not need to be plugged and offer great mobility, you’ll still be moving away from the device with the hose. You will want to ensure that you buy a model that can cope with jerking and occasionally falling over too.

A pressure washer with a sturdy frame and make will be able to cope with the most demanding of jobs no matter that is thrown at it.

Cleaning Power

Many people will make the mistake of picking a gas pressure washer that provides the most power. A lot of places will rate and promote these units based on how powerful they are. Don’t get me wrong, the main purpose of the washer is to blast dirt and grime off various surfaces and if you want to try and get the most power for your money then that is great.

The problem is that some of the most powerful gas pressure washers will lack certain features. This means that a less powerful model may actually be better as it has more functionality or perhaps it is more durable.

If you are basing your decision on cleaning power then the two most important things to look out for is PSI (pounds per square inch) and GPM (gallons per minute). PSI is how much cleaning pressure you will get and GPM refers to the amount of water that actually comes out of the washer. You should look out for a good balance between the two so that you get a good steady flow of water and an adequate power level.

Many mid to low range units are unlikely to offer the same raw power as a more expensive model but most will still pack a powerful punch.

Design And Features

It is vital that you have a look at what other features are offered with the unit.

Pay close attention to what else you are getting beyond PSI and GPM. Pressure washers should come with a range of nozzles which will allow the unit to tackle a range of different situations. Some pressure washers will have 4 nozzles, some will have 5 nozzles and others may have even more.

You will also find units that have separate detergent tanks if you want to get a really deep clean. You should also pay attention to the frame to ensure that it can cope with being tipped over, withstand bumps and offer adequate protection to the unit overall.

Conclusion

All of the gas pressure washers that are listed above are capable of heavy-duty cleaning. This includes walls, driveways, sidewalks, and fences. Some of the units also let you use detergent and other chemicals to get at those tough to remove stains.

Gas washers have the advantage that they don’t have to be plugged in and you can use them practically anywhere. You won’t need to be beside a power source to get it started. Although they aren’t the best option for small enclosed spaces due to the fumes, they still offer mobility which you don’t get with other models.
