How to Choose the Best Water Cannon Gun

What factors should you consider when selecting the best water cannon gun? Let’s take a look at everything we considered when ranking the best water cannon guns. A variety of water cannon guns could be good for different reasons, you just need to decide which factor is your top priority before deciding which tool to purchase.

How You Use It

While many water cannon guns can be used for all your needs, some are going to function better than others for different tasks. The primary thing to consider, are you going to use this more to clean your vehicle or to power wash stubborn dirt off of patios?

If washing your car is a top priority, you’re going to want an option that has a built-in soap dispenser and allows you to get a soapy foam. Whereas, if you’re looking to wash dirt and grime, soap is less of a priority than how powerful the stream of water is.


There are a variety of different price options to choose from when you’re deciding when what water cannon gun to purchase. We’ve reviewed a bunch of different water cannon guns in almost every different price range, and we determined that you can get a good cannon gun at any price range.

Consider this video that shows the differences between a water cannon gun and a pressure washer. You’ll learn about what is available in terms of quality and price. In this video, you see different pressure washers and water cannon guns cleaning a vehicle, so you can compare the quality of work.


This depends on your needs. If you are washing a vehicle you absolutely want to use soap with your water cannon gun.

But, if you are power washing a house or a patio, you might need soap. If you are looking to powerfully hose off moss, dirt, and grime, you can do that with just a heavy stream of water. You do not need to add soap to a surface like a sidewalk. In fact, adding soap might only make the surface slippery when you’re all done and need to walk on it.

You can also consider a water cannon gun like the one in this video. This water cannon gun can perform a variety of tasks like washing your car, or watering and fertilizing your plants. It can be used either with soap or without soap.

Water Pressure

If you are using the type of water cannon gun that attaches to a garden hose, then you will be limited to using the water pressure that is available through your faucet.

When the water cannon gun attaches to a pressure washer, then we can look at water pressure. In general, the higher the pressure the more effective your tool is going to be. You’ll be able to clean more with a higher pressure. For most tasks, you should find that pressure between 1,300 PSI and 2,400 PSI will be sufficient to meet your needs.


You might decide on a certain water cannon gun based on how often you need to use it. Some are made for repeat daily use, and others are more served for less use and good for yearly spring cleanups.

Best Water Cannon Gun Brands

There are many different reputable brands that sell water cannon guns:

  • DusichinDusichin is a company headquartered in China. They make a variety of car washing products, airless paint sprays, and hydraulic pressure test kits. You’ll find they make quality water cannon guns that are suitable for you if your primary focus is on cleaning your vehicle.
  • EZ Jet – EZ Jet is a popular brand, and they have a variety of water cannon gun options. Their products are best suited if you’re looking for water cannons that attach to a garden hose, as they can serve the added purpose of watering your lawn.
  • ProwessPro – ProwessPro sells a variety of garden tools. They have a water cannon gun that is a good option if you are looking for one with a long extension.


Q: Is a water cannon gun the same thing as a pressure washer?

A: Not exactly. You can use a water cannon gun with a pressure washer in most cases. However, some are also specifically designed to be used with a garden hose, and will not work with a pressure washer. Pay attention to the specific model you buy, and be sure to read the manufacturer’s manual before using your tool.

Q: Does water temperature matter when using a water cannon gun or a pressure washer?

A: While using cold water will not harm anything, it might cause your job to last longer. By using hot or warm water, your water cannon gun and/or power washer is going to be more effective and clean quicker. Using cold water might leave some greasy streaks behind, or cause you to clean things more than once in order for them to come truly clean, whereas hot water should eliminate grease and grime on the first try.

Q: How does a pressure washer work?

A: Water cannon guns can be very effective when used with a pressure washer. Pressure washing is done when you want to remove loose paint, dirt, mold, grime, etc. You can also use a pressure washer to give the exterior of your vehicle a deep clean. For example, if you park your RV under a tree and sap drips on it, you might want to power wash your RV, at least on the top where the sap landed.

Q: Are water cannon guns difficult to use?

A: Not particularly. It might take some getting used to, especially if you are accustomed to using something with less pressure, like just a hose. Here is a good video that walks you through how to use a water cannon gun when it is attached to a pressure washer. Once you get the hang of it, you’ll never forget the skill, and can easily use your new tool for years to come.

Q: Is it easy to pressure wash a house?

A: There are a lot of tips available if you are trying to pressure wash and clean the siding on your house. With the right tools, it is not too difficult of a task. A water cannon gun attached to the pressure washer will help make your job easier as if the siding is extra dirty, you might be able to add soap to the water cannon, which will help remove the dirt and grime.

Final Thoughts

The best water cannon gun for you is probably the pressure washer cannon gun with a 21-inch extension. It can be used with a variety of either gas or electric pressure washers, and also has 5 different nozzles to help control the pressure. It’s versatile, and the long 21-inch extension can help you clean those hard to reach places.

If you do not need to buy one with a long extension, then I’d probably take a good look at the Voodoo Pressure Washer Cannon Gun, as it’s a great option for cars, and creates a foamy soap lather that will really help you clean well. Having that extra foamy lather can really make cleaning your car a lot easier.
