What Is a Foam Cannon?

A foam cannon, or a pressure foam cannon, is a piece of equipment used to extend the capabilities of a pressure washer. Foam cannons are compatible with both gas pressure washers and electric pressure washers and can stand the PSI rating of most pressure washers. A foam cannon needs a minimal PSI rating to produce rich suds using a detergent or a soap. Using foam cannons can minimize scratching and keep the car paint in a healthy condition.

Benefits of Using a Foam Cannon

Benefits of Using a Foam CannonBenefits of using a foam cannon include saving time, money and detergents, eco-friendliness, functionality, and multi-purpose utility.

1. Saving Time

Setting up a foam cannon to a pressure washer and cleaning the surface takes up to 5 minutes. By attaching a foam cannon to a pressure washer that is set on the highest setting, suds can be produced instantaneously.

2. Resourcefulness

Using foam cannons saves water, detergents, and it is safe for the environment. Foam cannons use a small amount of soap and minimum amount of water to produce thick suds, which makes it easier to dispose of dirty water in places that don’t have proper drainage.

3. Functionality and Multi-Purpose Utility

Foam cannons can be used with pressure washers for cleaning cars, RVs, motorcycles, heavy-duty machinery, grills, driveways, and parkways. Foam cannons can be used for cleaning both smaller and larger surfaces, as long as it is used with a pressure washer set to the right PSI setting.

How Do Foam Cannons Work?

When connected to pressure washers, foam cannons use pressure washers’ GPM and PSI ratings to create a lot of suds, grouping them into thick and dense foam. Foam cannons are designed as attachments for pressure washer wands and usually having ¼ inch connectors. When using foam cannons with residential and commercial pressure washers, connector gauges should be used.

1. The Intake

The foam cannon intake is a part of the foam cannon that lets all the pressurized water into the cannon itself. The intake is a small coupler with a ¼ inch opening. The intake needs to click directly to the pressure washer wand or it can be connected to the pressure washer hose directly. The foam cannon intake should be fully operational and it shouldn’t leak, otherwise, the pressure will drop significantly, making the foam cannon dysfunctional.

2. The Flow Adjustments

Foam Cannon Reviews

Different dials can be found in the middle of the foam cannon, right above the container. Most commonly, a foam cannon has two different control settings – soap and flow adjustments.

  • Soap adjustment is a little valve used to control the amount of the top-rated foam cannon soap that goes through. By leaving the soap adjust valve open, only water can pass through it while leaving it in the opposite position will allow for a large amount of soap to go through and produce suds.
  • Flow adjustment is a cylindrical cover that can be dialed clockwise and counter-wise and it is located next to the output. Turning the flow adjustment changes the direction and flow of the output coming from a foam cannon to a straight line when the pressure washer is set on the highest pressure, or a wider line when it is set to a lower setting.

3. The Container

The container is the biggest part of the foam cannon made of plastic and equipped with a threaded screw head. If the pressure washer soap bottle doesn’t fit snugly onto the cannon, either the pressure coming from the pressure washer will drop or the soap will stop coming out, while the threaded screw head prevents safety threats. Most foam cannons have 33-oz to 1-liter containers that come with tubes that suck the soap solution.

4. The Output

Foam cannon output sprays out all the foam and thick suds out. Foam canon output is wider than the output of a pressure washer wand. The flow controller is located near the output and it prevents accidental changes in the pressure washer setting.

Foam Cannon Car Wash vs. Foam Gun vs. Hand Wash

Foam cannon car wash, foam gun, and hand wash differ in power capabilities, practicality, and budget.

1. Power Capabilities

Foam Cannon vs. Foam Gun vs. Hand Wash

The power that should be used to foam up and wash a car depends on two main factors – the pressure exerted to get foam density and chemicals used in the process.

Hand wash requires elbow grease and more time to wash a car. Almost any type of soap and detergent can be used for car hand washing, under the condition that it is not hazardous for the skin or the paint.

A foam gun is powered with the pressure that a garden hose can deliver, which is around 80 PSI. The type of chemicals that can be used with foam guns is narrow since dense foam is needed for car washing.

Foam cannons utilize the PSI of a pressure washer, with the lower threshold average of 800 PSI, providing the strongest power delivery compared to hand washing and foam guns. When used with the right detergent, foam cannons and pressurized water can make the thickest suds and the densest foam that emulsifies all the dirt and grime from the car surface.

2. Practicality

The biggest advantage of hand washing is that it doesn’t require any electricity, yet it takes a lot of time and it is not efficient with dirt deposits such as soap guns or foam cannons.

Soap guns don’t need electricity to operate, but need an operating hose that is easy to set up. The reach of a soap gun is higher than with hand washing, but it depends on the water pressure and the hose’s length.

Soap cannons provide better reach than hand washing and soap guns do. The reach of a foam cannon is adjustable on the spot by turning the valves, as well as adjusting different spray patterns and spraying directions, which provides greater precision.

3. Budget

Only water and detergent are needed for hand car washing, however, this way, a lot of soap is wasted. Soap guns are affordable but have reach limitations and aren’t efficient with stubborn stains. Foam cannons use the least water and detergent while still providing rich lather and lots of foam, which makes them affordable.

Foam Cannon Buying Guide

Foam Cannon Buying GuideWhen buying foam cannons, factors such as connector materials, container specifications, soap intake dial, and stream shape and spray pattern should be considered, all of which are listed below.

1. Connector Materials

Connectors and valves are the most important inner pieces of foam cannons. Connectors and valves regulate the foam cannon’s pressure, soap intake, precision, and reach. Brass connectors are most resilient and can withstand high PSI and GPM ratings and are durable and high-performing.

Some foam cannons have plastic parts that can warp under high temperatures, while synthetic materials can withstand the temperature but can’t regulate the water pressure properly.

2. The Container Specs

Foam cannon containers have different specifications – size, shape, transparency, and thread.

2.1. Bottle size

Most foam cannon bottles have 33fl oz 1-liter volume, which is the amount needed for washing a regular-sized car once or twice. Some foam cannon soap bottles can be used for storing leftover soaps and other washing solutions, which is indicated on the bottle.

2.2. Bottle shape

The shape of the foam cannon bottle determines how easy it is to hold it and connect it to the pressure washer. Most bottles have cylindrical containers that narrow down to the spot where they connect to the foam cannon. Bottles with dents located down the middle can be used with high-pressure foam cannons and pressure washers since dents provide a better grasp.

2.3. Bottle transparency

A foam cannon container should be transparent because of the practicality – so it can be seen how much of the washing solution is left inside. A transparent foam cannon bottle increases the resourcefulness of a foam cannon and allows experimentation with different foam cannon settings.

2.4. Bottle thread

Some foam cannons are threaded while others have a lock system similar to a buckle. A bottle thread is a more secure option and it is easier to put on and take off. If the thread does not slide in entirely, the foam cannon will start pushing the foam out to the side, which is a signal that the thread should be re-adjusted.

3. Soap Intake Dial

Foam cannons with accessible soap intake dials allow choosing the amount of suds made. The soap intake dial provides control over the amount of soap that is converted to foam, the thickness of the foam, and the suds density.  A soap intake dial enables cutting of the soap intake from the bottle and switching to using just water, which makes it highly versatile.

4. Stream Shape and Spray Pattern

The spray pattern adjustment on the foam cannon allows focusing the stream or covering larger areas. The spray pattern – the intake and spray pattern, allows adapting the foam cannon to different cleaning tasks.

How to Use a Foam Cannon?

How to Use a Foam Cannon

Steps on how to use a regular foam cannon are listed below:

  1. A pressure washer should be properly maintained and cleaned.
  2. The bottle should be detached and filled with 15 to 17 oz of warm water and 2 oz of soap and swirled for several seconds. The bottle shouldn’t be overfilled with soap, otherwise, that will affect the pressure negatively.
  3. The bottle should be attached to the foam cannon and the quick-release nozzle should be used for attaching the foam cannon to the pressure washer wand.
  4. The quick-connect male connector of the foam cannon should be connected to the female connector of the pressure washer.
  5. The pressure washer should be turned on.
  6. The dial form intake dial of the foam cannon should be set to the right setting and the foam should be sprayed across the surface in generous amounts.
  7. After 5 minutes, the soap intake should be cut off and the surface should be rinsed with water.

FAQ About Foam Cannons

1. Do foam cannons work?

Yes, foam cannons work and are capable of removing layers of dirt off cars and other surfaces without damaging them.

2. How much psi for foam cannon?

Foam cannons need at least 800 PSI to operate normally. The maximum pressure foam cannons can take depends on the model, although most foam cannons can withstand the pressure of any standard pressure washer.

3. How to clean foam cannon?

To clean a foam cannon, clean the thread of the bottle after each use, clean the brass on the outside using a non-invasive cleaner, and dry the foam cannon before storing it to prevent calcium deposits from forming inside, which can reduce the maximum amount of foam the foam cannon can deliver.

4. Do foam cannons work with any soap?

Yes, foam cannons work with almost any soap or detergent, except for dish soap, although there are specifically-formulated foam cannon soaps that produce more foam.

5. Will a foam cannon fit onto my garden hose?

Although some foam cannons can fit onto a garden hose, most foam cannons operate best when connected to pressure washers.
