Hand washing a vehicle, particularly a larger one like a pickup truck or an SUV, can take a lot of time and work. A foam cannon can simplify the process. When you hand wash your vehicle using a bucket and wash mitt, you can run out of suds. Foam cannons provide a continuous stream of foam, and you don't have to stop and refill a bucket to finish the job. 

Foam cannons also emit more soap that is thicker than what's dispersed through a wash mitt, so you don't have to scrub as hard to remove dirt and grime. Foam cannons, which are attached to a pressure washer, are a great item to add to your car washing arsenal because they are effective, easy to use, and provide the results you need in a shorter amount of time.

Our Methodology

I took several factors into consideration when choosing the best foam cannons. First, I made sure to choose products that are durable and designed to last. While I didn't have the opportunity to hand test all of the products in this list, I consulted consumer reviews and feedback to see how these units perform in real-world conditions. Some are made of higher quality materials and are more apt to last longer, so they made the list. I also checked the size of the bottles and how user-friendly each product was. Some have ergonomic qualities that make them easier to use. Those with adjustable spray patterns and other features also ranked higher. In addition, I made sure to choose foam cannons in a variety of price points to suit a wide range of budgets. For more information on our methodology, go here.

Best Foam Cannon Reviews & Recommendations

Specs

  • Brand: McKillians
  • Size:1 liter

Pros

  • Affordable
  • Ergonomically designed
  • Adjustable solution dispersal

Cons

  • Not as durable as some rival brands
  • May wear down in the neck area

We chose McKillans Snow Foam Cannon for a variety of reasons, least of which is the affordable pricing. The one-liter bottle is ergonomically shaped and the quarter-inch fitting will adapt to most pressure washer wands. There are adjustable valves which control the dilution ratio of soap and water as well as the spray pattern. The brass fittings that allow the cannon to adapt to a pressure washer wand are of high quality that will withstand lots of use. The ability to adjust the soap-water dilution allows you to target extra-dirty areas, wherein you can also adjust the spray pattern for maximum efficiency. A drawback of this product is that it may not necessarily withstand prolonged use. The translucency of the bottle weakens it, and it may end up tearing at the base of the neck.

Specs

  • Brand:Blisstime
  • Size:1 liter
  • Pressure washer requirements: 2 GPM and over 1000 psi

Pros

  • Affordable
  • Reference marks for measurements
  • Adaptable to most pressure washers
  • Adjustable valves

Cons

  • Not as high-quality as some competitive products

Washing your car doesn’t have to cost you extra each month, especially with the foam cannon package from Blisstime. Included with the foam cannon is a wash mitt you’ll find handy when it comes to spreading all those soapy suds around. We appreciated that the bottle included reference marks for measuring out the soap to water dilution ratio. The quarter-inch fitting on this foam cannon adapts to most pressure washer wands and the brass composition allows for durability and longevity. Adjustable valves control the amount of soap distributed as well as the direction of the spray pattern. The biggest problem we see with this product is that although it’s affordable, the quality may not be similar to higher-priced alternatives.

Specs

  • Brand:Chemical Guys
  • Size:32 ounces

Pros

  • Pressure washer not required
  • Good pouring accuracy
  • Spray nozzle included

Cons

  • Lacks adjustability

It could be said that there are more people who own a garden hose than a pressure washer. For this reason, we chose the Chemical Guys Foam Blaster Wash Gun as an alternative to pressure washer-specific foam cannons. The wide neck allows for increased pouring accuracy and the bottle still holds about a liter of liquid. What the Foam Blaster Wash Gun lacks is adjustability. Sure, you can move the nozzle of the foam gun itself to direct the spray, but you won’t be able to adjust the dilution ratio on the fly. At the same time, the adaptability of the product itself makes it an easy solution for anyone with a dirty car, house, motorcycle, RV, lawn furniture, etc.

Specs

  • Brand: MTM Hydro
  • Size:N/A
  • Pressure washer requirements: 1.8 to 5.3 GPM and 1,100 to 5,000 psi

Pros

  • Easy to grip
  • Sprays up to 20 feet
  • Easy to use
  • Adjustable nozzles

Cons

  • Instructions aren’t the best
  • May leak over time
  • Bottle can easily tip over

The MTM Hydro foam cannon sprays foam up to 20 feet either vertically or horizontally onto your vehicle, RV, boat, house, sidewalk, etc. It features adjustable fan blades and an easy-to-grip bottle. You can increase or decrease the foam output using the knob on top. The device requires 1,000 psi or higher to operate and includes 1.1 mm and 1.25 mm orifices. However, the instructions are not very good, and there have been some complaints that the quick-connect piece may not seal properly and can leak. Also, the bottle is not very wide and can easily tip over. The adjustment knob turns too easily and doesn't lock into place.
Easiest To Operate
Dusichin Foam Cannon

Specs

  • Brand:Dusichin
  • Size:1 liter
  • Pressure washer requirements: 1.2 GPM and over 1000 psi

Pros

  • High-quality components
  • Adjustable nozzle
  • Easy to operate
  • Doesn’t require a lot of soap

Cons

  • Top heavy
  • Can be a hassle to affix to a power washer

This foam cannon has high-quality brass connectors and a one-quarter-inch quick disconnect fitting. The bottle is 33 ounces, and the spray nozzle is adjustable. The top knob controls the foam thickness, and you can use this blaster for cars, motorcycles, windows, driveways, and more. It works with pressure washers with 1.2 GPM and over 1,000 psi. Unfortunately, the nozzle is pretty hefty, and the entire bottle with the nozzle attached is top-heavy. It can also be a bit awkward and clumsy to attach to a power washer.

Specs

  • Brand:Twinkle Star
  • Size:N/A
  • Pressure washer requirements: 2 GPM and over 1000 psi

Pros

  • Five adjustable nozzles included
  • Heavy-duty brass core
  • Doesn’t require a lot of soap
  • Easy to fill

Cons

  • Heavy and can be fatiguing to use
  • May leak from the top
  • No measurement levels

The Twinkle Star foam cannon comes with five nozzle tips and a one-quarter-inch quick-disconnect fitting. Its core is made of heavy-duty brass to prevent leaks. The nozzle can be adjusted to produce a wide to narrow spray pattern, and a knob on top controls the foam thickness. Pressure washers must have 2.0 GPM and over 1,000 psi for it to operate properly. However, it's a little heavy, which may fatigue your hands while you're using it. And while it's sturdy, it has a tendency to leak from the top. Also, the fittings are not the best quality, and the bottle doesn't have measurement levels.

Specs

  • Brand:Tool Daily
  • Size:1 liter
  • Pressure washer requirements: 1000 to 3000 psi

Pros

  • Five nozzle tips included
  • Adjustable knob
  • Dispenses a thick foam
  • Well-made

Cons

  • Not compatible with all pressure washers
  • Knob may require frequent adjusting

The Tool Daily Foam Cannon is great for cleaning cars, motorcycles, trucks, SUVs, roofs, driveways, windows, and more. The one-liter cannon has a quarter-inch quick connector and includes five nozzle tips: 0 degrees, 15 degrees, 25 degrees, 40 degrees, and 65 degrees. Simply connect the device to a pressure washer gun or wand after filling it with soap and warm water, then adjust the knob based on the amount of foam you want to dispense. Overall, it's simple to set up and easy to operate. Unfortunately, it doesn't work with all pressure washers, such as some models made by Craftsman. There have also been some complaints that the knob to control the spray pattern doesn’t stay in position very well, and you may have to adjust it frequently.
Best Warranty
TriNova Foam Cannon

Specs

  • Brand:TriNova
  • Size:N/A
  • Pressure washer requirements: 1.4 to 5.3 GPM and 800 to 3200 psi

Pros

  • Extra-wide neck
  • Nozzle fits most equipment
  • Produces a thick foam
  • Easy to use

Cons

  • Nozzle may require frequent adjustments while operating
  • No measurement levels
  • Top heavy when empty

The TriNova Foam Cannon works with a pressure washer and requires a quarter-inch female quick connect. After filling the bottle with soap, attach it to the pressure washer, adjust the knob, and commence the cleaning process. The product has an extra-wide neck that's designed not to crack, and the nozzle adapter connector fits most equipment. Users report that it produces a thick foam, and it's easy to pour soap from a container into the wide-mouth opening without making a mess. The company also backs up its product with a 100 percent satisfaction warranty and will replace the product or refund the purchase if you're not happy with its performance. One downside is that you may have to adjust the nozzle after each use, and it only sprays foam vertically. The bottle also doesn't have any measurement marks, so you don't know how many ounces are being used.

Our Verdict

Our pick for the best foam cannon is the McKillans Snow Foam Cannon due to its affordability and capability. For a more budget-friendly option, consider the Blisstime Foam Cannon with Wash Mitt. Simply add a wash mitt with the foaming action of a foam cannon, and you’re on your way to having a cleaner vehicle. 

Things to Consider Before Buying a Foam Cannon

Pressure Washer Requirements

There are two specifications you’ll want to pay attention to when buying a foam cannon. The first is the rate of water flow through the cannon itself. Many can handle upwards of two gallons per minute (GPM). This characteristic will be listed alongside the pressure (in pounds per square inch, or psi). Foam cannons typically require between 1,000 and 3,000 psi. Pressure washers of light to medium duty have a pressure of anywhere from 1,400 to 2,500 psi, so make sure you check your power washer specifications and align them with the specifications of the foam cannon you choose.  

Bottle Size and Shape

Many manufacturers differentiate themselves based on the shape of the foam cannon they sell. Most bottles will have a capacity of around one liter or 32 to 33 ounces, but it’s the shape of the bottle itself that you’ll want to pay attention to. Most foam cannons resemble a scuba tank. A short, broad neck sits atop wide shoulders that drop straight down the length of the cannon. However, some manufacturers add an ergonomic twist which makes it easier to hold the cannon as you loosen and tighten it.  

Quick-Release or Quick-Detach

You won’t necessarily have to worry about searching for a quick-release foam cannon because most products on the market include this as a standard feature. However, you will want to make sure the platform you are working with accepts the quarter-inch fitting found on most foam cannons. There are ways of adapting your platform to the quarter-inch fitting, but it’s better to be aware of this concern before you purchase a product. Quick-release fittings are desirable because it allows you to store the pressure washer without the foam cannon attached, and you can also easily switch between spraying foam and rinsing the vehicle.

Adjustable Dilution Ratio and Spray Pattern

Just like with a pressure washer, sometimes you’ll want to adjust the water spray pattern to more easily direct water towards a specific area of concern. Being able to do the same with a foam cannon allows you to target hard-to-reach areas that require special attention. The ability to adjust the dilution ratio of your foam cannon is another great feature. That way you can go heavy on the areas that need more attention — think wheel wells and front grilles — while staying lighter across the paint and windows, for example. 

Foam Cannon Pricing

Many foam cannons cost around $20. They are often made of plastic and include a brass core nozzle with quarter-inch fittings that are easy to connect and disconnect from a pressure washer. You may find some with accessories, but you typically have to pay a little more for extras such as interchangeable nozzles, wash mitts, and soap. These units can cost upwards of $60. The most expensive foam cannons can cost between $75 and $100 and are designed for professional purposes. They feature the highest-quality materials, are designed to last, and feature controls that allow users to efficiently adjust them to suit specific purposes.

FAQs 

You’ve got questions. The Drive has answers.

Q: Do you need a pressure washer for a foam cannon?

A. Some require a pressure washer, but there are those that only require a regular garden hose. It’ll depend on which model you go for.

Q: Is a foam cannon better than a foam gun?

A: A foam cannon connects to a pressure washer, while a foam gun works with a standard water hose. The latter typically doesn’t produce as thick a foam, but it will still loosen dirt from the surface of the vehicle. If you don’t have a pressure washer, a foam gun is a great alternative.

Q: Should I rinse my vehicle before using a foam cannon?

A: Rinsing first can remove surface contaminants such as dirt and brake dust. This will help the foam do its job to further clean your vehicle.
