What Is a Foam Cannon?

A foam cannon is a car washing equipment that works with a pressure washer. The product has a container where you mix water and soap and adaptors for connecting your pressure washer.

This tool uses the pressure from your gas or electric washer to create a soap and water mixture that resembles foam when sprayed on a car. Unlike the soap from a two bucket system or wash mitt, this foam clings to your vehicle.

A foam cannon reduces the stress of going back and forth from the bucket to the car. It also eliminates the risk of scratching your vehicle with particles from the bucket. Because the foam is thicker and clingy, it’s more effective for loosening the grime and dirt on your vehicle.
Foam cannons are designed for non-touch car washing. They use high-pressure foam and water to remove the contaminants on your vehicle. You can also use them to prepare your ride for hands-on wash. It will be faster and even fun, too.

You might think foam cannons are over-hyped. But you will know the difference when you use one. They are faster, more effective, and deliver great results.

You only need to know how to choose the right one for your car. And that’s what we will cover in the next section.

Foam Cannon Buying Guide

A foam cannon is a relatively novel car washing hardware. So it is not surprising if you find it difficult to choose one of these products for home or professional use.

That’s why we researched the top brands on the market and created this in-depth buying guide. After reading this guide, you will be able to choose a top-quality foam cannon with confidence. Here we go!

Top 6 Considerations When Buying a Foam Cannon

Before you invest in a foam cannon, it is vital to consider these factors:

  1. Versatility

    You want a foam cannon that is versatile enough for cleaning your car, the driveway, and other surfaces. A few brands have nozzles designed specifically for washing cars and nothing else. But you can get models that can clean almost every other object that can withstand the force of a pressure washer.
    To get the best out of your investment, go for multipurpose foam cannons. Thankfully, all the brands reviewed here are extremely versatile.

  2. Quality of Materials

    The quality of the materials used to make a foam cannon is crucial. People have reported buying models that arrived crooked or won’t thread properly. There are lots of complaints about the cover of the plastic containers cracking after a few times.
    You can avoid these problems if you buy a brand with a heavy-duty container and brass covers and adapters. Brass is the ideal material for the cover. It tolerates the soap and water mixture, the pressure, and doesn’t break easily.
    The best part is that high-quality foam cannons are still affordable. So you have no excuse to settle for inferior models.

  3. Capacity

    You want to buy a foam cannon with a large plastic container, particularly about 30 to 33 ounces. This will allow you to mix a large amount of soap and water to work nonstop for extended periods.
    Smaller bottles will require constant refills. This can reduce your productivity and increase the time you need to complete washing vehicles.
    Meanwhile, an oversized foam cannon may also make car washing more tedious. The ideal size is the one you can work with easily.

  4. Method of Delivery

    Do you have a pressure washer or use a garden hose? Most foam cannons can only work with a gas or electric pressure washer. But a few companies make models compatible with your regular washer.
    The problem is that garden hoses lack the force of pressure washers. This means you may need more time and effort to clean your car. It’s best to invest in a pressure washer if you want to enjoy your foam cannon.

  5. Connectors

    High-quality foam cannons come with multiple connectors for easy adjustability and use. Look for brands with brass connectors because these are the most durable and won’t leak water pressure. Plastic connectors are weaker, so they break easily and are less efficient.
    The more connectors, the better. Some brands we reviewed come with five different connectors. That way, you can adjust the pattern and volume of the foam to suit the object you are washing.

  6. Transparent Bottle

    A transparent bottle allows you to monitor what’s left of your cleaner while washing the car. This will allow you to work in confidence without the need to stop to check the soap level. Some brands calibrate the side of the bottle to help you better track the cleaner you have left.

7 Important Foam Cannon Features & Specs

Here are essential foam cannon features and specifications to look out for before buying:

  1. Pressure Washer Requirements

    When shopping for a foam cannon, check the pressure and water flow requirements of the pressure washer. The water flow is measured in gallons per minute (GPM). Most high-quality brands have containers that can handle 2 gpm.
    The other important specification is the pressure in the hose, measured in psi or pounds per square inch. Most foam cannons can tolerate pressures of 1,000 to 3,000 psi. A few models can accommodate over 4,500 psi without damage.
    It is important to buy a foam cannon compatible with the gpm and psi ratings of your power washer.

  2. Bottle Size

    Foam cannon bottles are rated in ounces or liters. The best models provide up to one liter or more of container space to allow you to work for longer without refills. A bottle rated 30-33 ounces will be a good choice, especially if it’s for home use.

  3. Bottle Shape

    This feature can make or mar the utility of your foam cannon. Most foam cannons have a shape which makes it difficult for them to stand upright when empty.
    User reviews show that smaller necks are prone to cracks than wider types. Some brands feature designs for easier tightening and loosening of connectors. If possible, choose a foam cannon with an ergonomic design.

  4. Foam Thickness Dial

    A great feature to have in foam cannons is the ability to change the dilution ratio. This will allow you to use heavier foam on areas that need more attention and lighter suds on the paint and windows. Brands that have this feature come with a dial you can adjust to regulate the foam thickness.

  5. Adjustable Spray Pattern

    Being able to change the spray pattern can allow you direct the foam to specific areas for maximum impact. Manufacturers that offer these features provide additional adapters for foam pattern adjustment.

  6. Quick Detach Adapter

    Quick detach connectors make it easy to switch from spraying foam to rinsing the vehicle. They also allow you to remove the pressure washer gun easily from the foam cannon, reducing the hassle of storage.
    Most brands come with quick release adapters. However, check that your pressure washer is compatible with the 1/4″ connector found on most foam cannons.

  7. Threaded Bottle

    Here, we are referring to the top of the bottle where you install the brass connector. A threaded bottle marries the container and connector seamlessly, eliminating pressure leaks and any crookedness. If the unit doesn’t thread on easily, the foam cannon bottle feels loose and may even drop during use.

Should I Buy a Foam Cannon?

foam cannon vs foam gun vs hand wash

Foam Gun vs. Foam Cannon

We’ve seen many people ask in user reviews whether there is a difference between a foam gun and foam cannon. Well, there are many differences between the two products.

The major similarity between both tools is that they produce foam for washing. To understand the two better, let’s take a closer look at the foam gun and the foam cannon.

  • Foam Gun

    The foam gun produces suds for washing cars and other objects. It is designed specifically for use with a garden hose and requires limited pressure.
    A foam gun is extremely affordable and easy to use. In fact, its ease of handling makes it ideal for home use.
    A foam gun lacks the pressure to agitate the soap and water mixture and uses generic cleaners. So, it produces thin suds.
    If you are looking for heavy foams, this is not the product for you. But you can use a foam gun with almost any car soap if you don’t have a pressure washer.
    This product takes more time to dissolve the grime on your car and may require extra hand washing. But it works if you are looking for a foamy solution to a shiny car. A foam gun is ideal if you fear high pressure may damage your car paint.

  • Foam Cannon

    A foam cannon also produces suds for washing cars. But unlike the gun, the cannon is designed to produce thick foams under pressure using a power washer.
    Foam cannons are also easy to use but do a better job of cleaning your car in less time. This is because a pressure washer has more force to remove the contaminants on your paint and the hard-to-reach areas on your vehicle.
    Meanwhile, foam cannons have dedicated soaps, although generic car cleaners will do. They are popular in professional detailing shops, but simple enough for home use.
    Foam cannons are more powerful than foam guns, produce thicker suds, and require less effort. However, they are more expensive but still affordable. A foam cannon is an awesome piece of car washing gear if you love touchless car washing.

Foam Cannon vs. Hand Wash

Should you use a foam cannon or handwashing? Well, it depends on your ownership of a power washer. If you have a pressure washer, nothing beats the ease the tool brings to your car washing experience.
Regardless of how dirty your car is, a foam cannon is better than hand washing, for many reasons. First, the pressure washing removes most of the road grime on your car, making rinsing less tedious.
Second, pressure washing means you don’t have to use a sponge on your car. Sponges can hold particles that will leave scratches, and swirl marks on your vehicle. Also, handwashing can add more contaminants to your vehicle as you dip the sponge in the dirty soap.
We understand that hand washing your ride may be inevitable sometimes. But even stubborn, caked grime and mud will give way after soaking in foam. You only need to know the correct way of using a foam cannon to get the best results.
If you own a pressure washer, a foam gun is an excellent tool for reducing the tedium of car washing. It is especially effective for touchless washing.

5 Benefits of Using a Foam Cannon

Foam cannons offer several advantages over traditional car washing methods. Here are some benefits of using a foam cannon:

  1. Faster Washes
    One reason for the popularity of foam cannons is their speed. With this tool, you can quickly cover your whole car in thick foam that will cling and dissolve contaminants. The swiftness is thanks to the power of the pressure washer which makes foam production and application a breeze.
  2. Saves Water and Soap
    Foam cannons use less water and soap to make your car clean. Most of the washing is done under pressure, not by the volume of water. This is also one advantage of foam cannons over foam guns.
    Foam guns require more water to clean surfaces because the water jet lacks the bite of the pressure washer. Using a foam cannon can make your car soap last longer and prevent the waste of water.
  3. Prevents Scratches and Swirl Marks
    Foam cannons can prevent your car from getting scratches and swirl marks. With a pressure washer-powered foam cannon, you need not apply a mitt or sponge on your car paint. This reduces the chances of stray particles scratching your expensive paint job.
  4. Saves Cost
    A foam cannon delivers professional results if you know how to use it. If you buy a quality model, you can say bye to expensive and less effective car washes. All you need is a quality car soap and a compatible pressure washer.
  5. Versatility
    Foam cannons wash more than cars, although their primary use is for cleaning vehicles. These products make light work of your dirty driveway, porch, outdoor furniture, and gutters. You can also use foam cannons to clean motorcycles, RVs, trailers, boats, and machinery.
    After washing your car with a foam cannon, lock in the shine with a car wax. Check out this article to know what to look for when choosing car wax.

How Do Foam Cannons Work?

Foam cannons are easy to use. They use pressure to create foam for washing a car or any other surface. All you need to do is add soap and water to the foam cannon container. Then attach your pressure washer lance and start spraying.

The foam this tool creates is unlike what you get with a mitt and soap combination. Foam cannons produce thicker suds which cling to your car for longer.

Wait for a few minutes and watch as the dirt leave your paint. Once the foam has changed color, rinse it off with the pressure washer. Then you can use a wash mitt to remove the remaining dirt and contaminants on your car.

Sometimes, you can even spray the foam twice. The foam not only makes washing easier, it acts as a cushion on the paint surface. This reduces the risk of scratches and swirls during the washing process.

How to Use a Foam Cannon in 5 Steps

Follow these steps to wash your car with a foam cannon:

how to use a foam cannon

  1. First, unscrew the fluid container and fill it with warm water and car soap. Check the user directions for the ideal soap water ratio.
  2. Apply pressured water to the car to remove superficial dirt and debris from the surface.
  3. Attach the foam cannon to the pressure washer lance or wand with the quick release nozzle.
  4. Spray thick foam all over the car and wait for a few minutes until the suds start dropping off the vehicle.
  5. Complete the washing with a two bucket wash method or use the touchless technique.

To get the best out of your foam cannon, you will need a top quality car wash soap. Here is a comprehensive car wash soap buying guide for the lowdown on buying the best products.

Top Foam Cannon Tips & Tricks

Using the correct method can help you get the best results from a foam gun. Here are tips and tricks to help you maximize your foam cannon:

  • Use the correct soap and water ratio. This is important if you want to get those thick dirt-busting foam suds.
  • Learn the correct spray pattern and foam volume for different parts of your car. The grille, fenders, and other areas that see heavy road grime and dirt should get the thickest foam. Adjust the spray pattern and volume for the windows and paint to avoid damaging those fragile areas under pressure.
  • Ensure the tool produces snow foam and apply the white stuff evenly across your ride.
  • Let the foam sit for a while before washing it off. The time will depend on how dirty your car is and the soap. But 10 minutes is a good wait time.
  • Use your foam cannon in a dry place. This doesn’t mean you should wash the vehicle under the scathing sun. But the foam won’t stay on the vehicle when it is raining.
  • Rinse the foam off your car thoroughly. Any foam remnant will cause nasty spots on the paint and defeat the whole purpose of using a cannon.
  • If your car is very dirty, don’t forget to use a wash mitt to remove the dirt and debris the pressure washer and foam left behind.
  • If you are dealing with a lot of cosmetic defects on your paint, restore your car’s shine with the best car scratch remover.

FAQs & Answers

Here are commonly asked questions and answers about foam cannons:

  • Q: Why does the foam cannon move around when I connect it to the pressure washer?
    A: This problem occurs when the psi of your pressure washer is higher than the foam cannon can handle. Before buying a foam cannon, check that it is compatible with your power washer.
  • Q: Can I use a foam cannon with a public self-wash pressure washer?
    A: You can’t use a foam cannon with public pressure washers because their connectors are not compatible. Worst, you cannot use an adapter or remove the connector on these public utilities.
  • Q: Is it possible to use a foam cannon with a garden hose?
    A: Most foam cannons are designed for use with pressure washers. The foam gun is the tool that works with a garden hose. But there are a few brands that provide adapters that allow you connect a foam gun with a garden hose.
  • Q: Can I use a generic car wash soap other than the one the foam cannon manufacturer recommended?
    A: Yes, foam cannons can use most types of car wash soap. So long as you use the correct dilution ratios, the tool will deliver abundant suds with the right thickness.
