5 Best Snow Foam Cannons: Tried & Tested

It’s so easy to neglect our cars. I’m guilty of it too.

When it comes to washing our cars, most people don’t find it fun.

We exaggerate in our heads the amount of effort that it takes to wash a car. This often results in endless procrastination.

The truth is, it doesn’t need to be hard work.

If you’re sick and tired of filling buckets, hauling them to your car, and using endless wash mitts, the snow foam lance could be a life-changer.

Foam cannons are by far the most popular pressure washer attachment. They make washing your car much less effort and greatly decrease the time spent washing it.

In this article, I will recommend what I believe to be the 5 best snow foam cannons available to buy today. I’ll also teach you what a foam cannon is, how to adjust their settings and what features to look for when buying one.

What Is A Foam Cannon?

A Foam cannon or Foam Lance is a pressure washer attachment designed to speed up the wash process and make it safer.

Using high-pressure water and soap products, you are able to cover a car in a thick soapy foam mixture within minutes.

It’s called a foam cannon for obvious reasons. They were designed with the purpose of applying snow foam to your car.

You can also fill a foam cannon with certain shampoos. This will let you wash your car without the need for wash buckets.

A foam cannon is not a foam gun.

Foam guns are designed for those without a pressure washer. They connect to a garden hose and are much cheaper, but they’re also way less effective.

Features To Consider When Buying A Foam Cannon

To the untrained eye, a lot of the foam cannons will look the same.

While they are very similar, there are a couple of factors that will influence your decision to buy each one.

I personally prioritize compatibility, capacity, and adjustable settings.

Capacity – If you’re working on a large car or truck, it’s crucial that you own a foam cannon that has a large capacity.

The last thing you want to be doing is running back and forward mixing up more product as you wash the car.

You should try your best to get a foam cannon that holds 32+ ounces.

I personally own the Karcher foam cannon, it only holds 18 ounces. It’s only just enough to wash my Volvo C30, though I’m definitely a little gung-ho.

Build Quality – A foam lance is a straightforward product but you’d be surprised at just how bad some of them can be.

Because the bottle is subject to high pressure, it should be made with strong and sturdy plastic. I once cheaped out and the plastic bottle felt nearly as thin as a ping pong ball.

The other key point is the connector. It’s under constant pressure and is the most likely to leak. When possible, try to choose a brass connector, though sometimes it may not be possible. (Karcher cannons are mostly plastic).

You don’t want a low quality foam cannon that sprays foam all over you, as well as the car.

Compatibility – When buying a foam cannon it’s crucial that it’s compatible with your pressure washer. If you can’t connect it, you cant use it.

Most industry-leading pressure washers have unique connectors. You will have to buy a foam cannon that is made specifically for your pressure washer whether it’s Karcher, Nifilisk, or some other brand.

Owning a pressure washer with a 1/4” connector will allow you to use most third-party foam cannons.

Having a pressure washer with a unique connector will limit the options you have. Though you are able to get adapters that convert specialty connectors to 1/4” connectors. Like this Karcher one

Adjustable Settings – Most people that are interested in snow foam, believe that a thick foam = better results. While that’s not necessarily true, it’s definitely more satisfying.

The best foam lances come with a dial on the top that allows you to control the water and air intake.

They’ll also have an adjustable nozzle which lets you change the spray fan width to achieve the best coverage.

Color & Transparency – My first foam cannon was a cheap Karcher one. It’s a silver/grey color and is made of very thick plastic.

While it’s not the most important factor in the world, choosing a light bottle or transparent bottle will let you see how much mixture is left.

It will also be easier when diluting products and filling up the bottle with water. When using the Karcher cannon, I often overfill it, covering my kitchen area in snow foam.

Best Foam Cannons

Now that you know what to look for in a foam cannon, you’ll be able to understand why I’ve recommended the foam lances listed below.

These are the best snow foam lances that money can buy (in no particular order).

They’ve have been selected from the hundreds on the market. Tried & Tested.

They are feature-rich, high quality and will provide you with soapy suds for many years to come.

TriNova Foam Cannon 

Tri Nova Foam Cannon

TriNova’s premium foam cannon is designed to create & deliver maximum suds.

When using Bilt Hamber Auto Foam & dilution ratios around 1:5, I was shocked at just how thick the foam was.

  • High-Quality Brass Neck
  • 1/4” Brass Quick Connect
  • 33 Ounce Container
  • Variable Spray Nozzle
  • Adjustable Air/Water Ratio Dial

As well as the mass amounts of suds, the build quality on this cannon is insane.

You can tell that they’ve really focused on creating a premium product. It’s clean, simple, and easy to use, what more could anyone want?

It completely outperforms the budget options, but that’s to be expected. It’s a premium cannon, priced in the middle of the market.

Adam’s Red Foam Cannon 

Adams Polishes is a well known detailing brand that prides itself on customer satisfaction and product quality.

When used with the optimal setup, this cannon will create a thick and clingy foam that destroys dirt and contamination.

  • 34 Ounce Container
  • Adjustable Spray Nozzle
  • Stainless Steel Connector
  • Adjustable Air/Water Ratio Dial
  • Visually Pleasing Bottle & Branding
  • Includes High-Quality SGS-28 Spray Gun

Now, if you are looking for a cheap option, you can rule this out.

The SGS-28 Spray gun costs $65 on its own. This package includes the gun and a smartly branded, sturdy container to go with it.

You get what you pay for, but you might not be able to justify spending >$50 on a pressure washer attachment.

My only complaint is that it’s very top-heavy when empty. It cannot stand on it’s own with unless it’s filled with product.

Matcc Adjustable Foam Cannon

Matccs’ Foam Cannon is a mid market option that’s got all of the features you may need and more.

The Inbuilt water filter is something that no other foam cannon on this list has. It prevents any rocks, dirt or debris from the container being picked up and thrown at your car.

While it’s rare that you’ll have debris in your foam, the filter is a nice touch and shows that they care about your car.

  • Inbuilt Water Filter
  • 1/4” Quick Connect
  • Variable Spray Nozzle
  • Adjustable Air/Water Ratio Dial
  • Heavy Duty Brass Core & Connector

I like the Matcc Cannon as an entry-level option. The light white bottle allows you to see the mixture easily and it still has all the adjustable settings that a premium cannon has.

Definitely good value for money, but the plastic bottle feels a little cheap. Could do with something a little bit thicker and heavier.

AutoCare Adjustable Foam Cannon

Upon researching foam cannons, I found that there were many third party cannons but I didn’t realize that very few of them supported Karcher Pressure washers straight out of the box.

Fortunately, there are some that are produced with the Karcher “Bayonette” connector but they are few and far between.

Autocares Adjustable Foam Cannon was the one that I found to be the best and easiest to buy.

It fits snug to any Karcher K Series Pressure Washer and produces a nice layer of foam on the car.

The tank is 34 Oz, almost twice the size of Karchers own foam cannon. And thankfully, the bottle is a light shade of white, allowing you to see the product as you mix and spray.

  • Variable Spray Nozzle
  • Transparent 34 Oz Bottle
  • Adjustable Air/Water Ratio Dial
  • Tight Sealing on the nozzle. 0 Leaks.
  • Compatible With All Karcher K Series Pressure Washers

Unfortunately, like every other Karcher compatible foam cannon, the connector is plastic. I would prefer metal, however, in this case, the plastic seems to be solid enough.

The truth is, without using adapters or being able to purchase the Autobrite foam lance, the Karcher Foam Cannon options are very limited.

You could say this is the best of a bad lot. But it still does the job.

AutoBrite Heavy Duty Foam Lance

Autobrite Foam Cannon

If you were to ask professional detailers “If you could only have one foam cannon ever, which would it be?” Most of them would answer with this.

The reason it’s so low on my list is the fact that it’s not easy to get in the US.

Autobrite is a UK company and they only seem to distribute through their branded website. They’re not listed on amazon or any other major US retail sites.

While they offer worldwide shipping, it’s going to cost over $70 to get this cannon to the states.

It’s a shame, because it’s a brilliant, heavy-duty foam cannon that offers support for almost every pressure washer you can think.

Should I use a foam cannon?

Using a foam cannon certainly has its benefits, but it’s not one size fits all.
Weigh up the pros and cons before proceeding with your purchase.

Pros
Satisfying to Use
Quickly wash cars
Increased Cleaning Power
Minimizes Potential Scratches

Cons
Controversial
Can become costly
Requires a pressure washer
Requires specific car wash products

I believe that there are more than enough benefits to using a foam cannon. It’s the reason that I upgraded from a non-branded pressure washer to a Karcher one.

I wanted to use a foam cannon because it makes cleaning the car easier, safer and more fun.

If you have the money to invest, it’s definitely worth your time. However, if you were to buy a pressure washer, foam cannon and snow foam, it could set you back over $200.

Using A Foam Cannon

Now that you’ve purchased one, you’ll now need to learn how to use a foam cannon. They’re very simple to use and are mostly plug and play.

Follow the steps below for a general guide:

  1. Measure and Dilute Snow Foam using warm water
  2. Connect the Foam Cannon to your pressure washer
  3. Spray your whole car evenly going from top to bottom
  4. Allow the foam to dwell for manufacturers recommended dwell time
  5. Rinse the foam from the car using your pressure washer

As well as the steps above, you should always work from the top down, making sure your car is evenly covered.

The worst thing that you can do is let the foam dry on your car. Avoid washing your car in direct sunlight, and don’t wait too long to rinse the snow foam off.

With a good setup and by following these steps, you will be able to make your car shine again. Quickly and safely.

Adjusting Foam Cannon Settings

As mentioned above, foam cannons often come with two settings that you can change. These are:

An Air/Water Intake dial which allows you to adjust the thickness of the foam. As you reduce the amount of water and increase the air intake, you’ll create a thicker foam.

Another way to increase the amount of foam would be to use more product in your foam cannon. Experiment with different dilution ratios.

Secondly, you can adjust the spray fan nozzle. Doing this will allow you to change between a narrow or wider fan.

The idea behind the adjustable spray fan is that you should adjust it based on the vehicles you are washing.

A wide fan would allow you to cover large vehicles quicker and more evenly. Whereas a narrow spray would be for a more targeted area, such as the wheel wells.

Best Snow Foam For Foam Cannons

If you haven’t already bought a snow foam to wash your car, I’ve compiled a list of the best snow foams.

Bilt Hamber Auto Foam

I love to use Bilt Hamber Auto Foam.

In my opinion, it’s by far the best snow foam on the market. It has incredible cleaning power, though its foam leaves a lot to be desired.

Bilt Hamber Auto Foam is one of the cheaper snow foams too.

Unfortunately, it doesn’t look to be available in the US.

If you’re a US citizen and are looking for a good snow foam, Chemical Guys HoneyDew Foam is frequently recommended among the detailing community.

You should also research how-to apply snow foam properly. If you’re using the incorrect settings and dilution ratios, no matter how good the product is, if you’re doing it wrong, you’ll get poor results.
