Best Foam Cannons to Soak Away the Dirt

Best Foam Cannons to Soak Away the Dirt

All car owners want their vehicle to look shiny and squeaky clean, ideally without too much hassle. Car washes are great, but the overall cost can add up over time. Why not treat yourself to a professional-grade car cleaning tool to be used whenever you wish in the privacy of your own home? Well, toss away that antiquated soap bucket; foam cannons are your ticket to success.

Foam cannons are a simple attachment to your average pressure washer. They spray thick loads of foam that can tackle the nastiest dirt and grime materials on your vehicle, but do it gently enough to keep from harming your paint job in the process. It sure beats the old fashioned soap/garden hose combo, that’s for sure!

In this article, we are going to focus on the best foam cannons out there on the market today. First, we’re going to showcase the bare minimum of what you should know about foam cannons before making an informed purchase. After that, we’ll get straight into the product reviews (because that’s what you’re here for, right?) Finally, we’ll cap off the article with an extended buyer’s guide that will enrich your understanding of foam cannons and the various complexities behind them.

Are you ready? Let’s dive into this bad boy so you can get closer to spraying down your car in no time flat!

Factors to Consider for Foam Cannons

Here are a couple of quick and easy points of consideration to make before purchasing a high-quality foam cannon for your auto needs. If you are wanting more information on foam cannons, please be sure to look at our extended buyer’s guide at the tail-end of our product reviews for a more in-depth look on the ins and outs of these types of products.

How You Will Use It

One of the first things you should determine before purchasing a foam cannon is the type of one you need to buy. Most foam cannons connect with either gas or electric pressure washers. Some, however, are manufactured to connect to your average backyard garden hose. We don’t recommend such things, however, since garden hoses can not expend as much raw power and force, making them far less efficient at car cleaning than a pressure washer and causing you to waste more time in the process of getting an even clean. Long story short: invest in a pressure washer if you intend to purchase a quality foam cannon!

Your Pressure Washer Stats

If you do go the pressure washer route with a foam cannon, it’s also important to know the nitty-gritty of your very own pressure washer. Be sure the foam cannon you purchase falls into the proper PSI/GPM range; otherwise, you might waste money on foam cannon that doesn’t match up with the specs of your pressure washer.

What Material It’s Made Of

In a lot of areas of life, the adage of “you get what you pay for” remains true. Foam cannons are no exception to this rule. Be sure to look for foam cannon options that are made of high-quality materials such as tough plastics that won’t degrade over time. Be sure that the connector and fitting materials are of high quality as well. Brass is the standard nowadays when it comes to these sorts of things, as it is a tough and reliable material and is prized for its resilience to corrosion and generally is not prone to rust unlike a lot of other metals.

Foam Quantity

Ideally, you’re going to want to go for a foam cannon that holds quite a bit of liquid, at or above 30 ounces. This will allow you to clean your vehicle for longer periods without having to constantly stop to refill the foam cannon. You can see how this can improve one’s efficiency as a whole. Don’t spend any more time washing your car than you have to!

Now that you know what to look for, let’s explore the best foam cannons on the market.

Top 10 Best Foam Cannons 2024

1. Best Overall Pick: MATCC Adjustable Foam Cannon

MATCC Adjustable Foam Cannon

Why we like it: This foam cannon has a lot of range in its foam output due to its high-quality foam lance mechanism.

Editor’s Rating:


  • Minimum/Maximum Pressure: 1000 PSI – 3000 PSI
  • Flow Rate: 2.0 GPM
  • Fill Capacity: 33oz


This is a great quality foam cannon that is inexpensive while also providing a lot of value in the process. Coming with a sizable 33-ounce bottle, you’re not going to be running back and forth trying to fill this bad boy up. This is great for impatient car owners that want to get in, clean their car, and go on about their day with zero hassle in between.

In terms of construction, this foam cannon is solidly built. It not only has brass connectors, allowing for a tightness that is conducive to strong levels of pressure, but it also has a body made out of durable brass as well. This product will certainly take a beating!

The big addition to this foam cannon is it has an adjustable foam lance. This allows the cannon a greater level of foam control concentration, which is useful for touch-ups and larger dirt-laden sections of your vehicle. The spray nozzle itself is also adjustable, making it easy to alter how wide or narrow you want your spraying pattern to be, overall.


This is one of the best low-cost entries to foam cannons. While its opaque design leaves something to be desired in terms of seeing how much soapy liquid you have stored in it, you really can’t argue with its price point as well as its highly adjustable nature. With this foam cannon, you simply cannot go wrong.


  • Adjustable water regulator
  • 33-ounce storage
  • Adjustable spray nozzle
  • One year warranty


  • The opaque design makes seeing the level of soap very difficult

2. Best for Home and Professional Use: Dusichin SFL-001 Adjustable Foam Cannon

Dusichin SFL-001 Adjustable Foam Cannon

Why we like it: This foam cannon is highly affordable and designed with both the professional as well as the layman in mind.

Editor’s Rating:


  • Minimum/Maximum Pressure: 1000 PSI – 3,000 PSI
  • Flow Rate: 2-5.3 GPM
  • Fill Capacity: 33oz


One look at this foam cannon and you can easily discern that it screams quality. This product is marketed for both home and professional use, bringing the best of both worlds into one package.

This foam cannon comes complete with high-grade brass connector parts that merge the cannon with a pressure washer. The brass connectors are a fantastic addition as they create a snug fit between the foam cannon and the pressure washer, ensuring maximum pressure is possible every step of the way.

Another great addition to this product is the sizable 33-ounce bottle attached to the foam cannon. This is more than enough to last many uses before it needs additional fillup of car soap. The Dusichin also comes with an adjustable lance which helps with changing up the soap/water mix for small little touch-ups that don’t require a lot of cleaning solution.


Much like the previous product the only real downside we could find with this foam cannon is its opaque design. This obviously can inhibit viewing just how much soapy fluid you have left, making ascertaining whether or not you need to fill up the foam cannon a bit more challenging than other models. However, as it stands, this is a fantastic product and a highly affordable option for the individual that wants to enter into the wide world of foam cannons without breaking the bank.


  • 33-ounce bottle
  • Foam thickness control knob
  • Brass connectors for maximum tightness
  • Incredible price
  • Marketed for both professionals and home-use


  • The opaque design makes it hard to see how much soap you have remaining

3. Most Nozzle Variety: Tool Daily Foam Cannon

Tool Daily Foam Cannon

Why we like it: This incredible foam cannon set comes with a variety of colored nozzle types that alter spraying angles.

Editor’s Rating:


  • Minimum/Maximum Pressure: 1000 PSI – 3000 PSI
  • Flow Rate: 2.0 to 5.3 GPM
  • Fill Capacity: 33oz


This powerful 33oz foam cannon comes with five different nozzle tips that can help you to get the best spray for your car. In fact, these nozzles justify the purchase of the product before we even get into the other great features of this foam cannon.

First things first, the nozzles themselves are each distinct in terms of color, making it very easy to know what you’re searching for right before a hardcore car cleaning session. Each one sprays at a different angle, giving you a lot of options in terms of how you can attack a dirty vehicle with ease and precision. Feel like changing your mind mid-spray? You’re in luck; each nozzle has a quick disconnect design, making impromptu nozzle changes quick and painless.

Another great feature of this product is that it is universally compatible with all commercially available pressure washers, and without needing any kind of special tools or fasteners. You’re always going to get a leak-free fit with this product.

To round out an already stellar foam cannon, this product also comes with a see-through design, which is fantastic for ascertaining just how much soapy product you have left during a washing session.


The only real negative thing we noticed with this product is that the foam production could maybe be a bit thicker, but as it stands it still produces more than enough to get the job done. When you consider all of the versatility that comes with the included color-coded nozzles and the universality of its design, you really can’t complain.


  • Five different colored nozzles for adjustable spray angles
  • Durable plastic design
  • See-through container design
  • Has a water regulator knob


  • The foam production could be thicker

4. MTM Hydro Professional Foam Cannon

MTM Hydro Professional Foam Cannon

Why we like it: This high-grade foam cannon is made for powerful pressure washers and can accommodate water pressure up to 5,000 PSI.

Editor’s Rating:


  • Minimum/Maximum Pressure: 1100 PSI – 5000 PSI
  • Flow Rate: 1.8 – 5.3 GPM
  • Fill Capacity: 32oz


This is THE foam cannon for spraying the thickest layers of foam you could ever dream of. If you’ve got a large vehicle and don’t want to spend a lot of time cleaning it, buying the MTM Hydro is a must!

Probably one of the most eye-popping features of the MTM Hydro is the fact that it can be used with pressures up to 5000 PSI. This is an incredible amount of pressure that will be able to blast away the nastiest of dirt, stains, and possibly anything else we can’t think of at this time! This product has an excellent flow rate as well, varying from 1.8 to 5.3 GPM, giving the user a level of control over the amount of sudsy water used at any given time.

The adjustable fan system in the nozzle can be finely tuned for extremely wide jets of foam. This makes it adept at large-scale cleaning jobs for bigger trucks and SUVs. It gives you the power and agency to fully coat a vehicle, then scale it down a bit for finer details. The versatility of this model of foam cannon cannot be understated.


Nothing’s perfect, not even this beast of a foam cannon. For starters, it’s a bit more expensive than most models on this list, making it a bad choice for an intro-level sud-slinger. On top of that, it’s a good idea to own a high-level power washer before even purchasing this product, as it requires at least 1,100 PSI to even be utilized decently, but more is recommended, especially for a beastly foam cannon such as this, otherwise you’re just not doing it justice.


  • High-powered foam cannon
  • Can go up to 5000 PSI
  • Adjustable fan for wider foam jets
  • Great for large vehicles


  • Requires a fairly powerful pressure washer to get the full effect
  • Pricey

5. Best Budget Pick: Fasmov Car Wash Adjustable Foam Cannon

Fasmov Car Wash Adjustable Foam Cannon

Why we like it: It seems boring on the outside, but this no-frills foam cannon more than gets the job done for a low price.

Editor’s Rating:


  • Minimum/Maximum Pressure: 1000 PSI – 2,320 PSI
  • Flow Rate: 2.0 to 5.3 GPM
  • Fill Capacity: 33oz


On the outside, this foam cannon seems really bare. In fact, amazingly enough, there’s zero indication that Fasmov even makes this product in the first place, as there’s no logo on the bottle itself! Don’t let the bareness of this foam cannon fool you, though, it does the job with the bare minimum.

As far as a connector for your pressure washer goes, it comes with a standard brass connector, ensuring a certain level of tightness for decent water pressure. The package is rounded out with a foam thickness knob, Again, nothing fancy but still very solid.

As far as the total amount of fluid, this thing holds 1L total, which is more than enough for several car wash sessions easily. On top of that, the bottle has a see-through design, so it is very easy to see the remainder of the cleaning solution you have left. There’s definitely no guesswork involved with this bad boy!


The biggest downside we found with the Fasmov foam cannon was that it doesn’t have as high of a maximum PSI as other models on this list, so if you’re looking for something that can crank out the highest water pressure possible, look elsewhere. However, if you’re willing to get your feet wet with an introductory foam cannon model, this might be a great place to start.


  • Affordable
  • Sturdy plastic build
  • No-frills design
  • Adjustable spray nozzle
  • See-through design


  • The maximum pressure is lower than other models

6. Best Premium Pick: TriNova Foam Cannon

TriNova Foam Cannon

Why we like it: TriNova is a brand known for giving consumers the premium option when it comes to foam cannons, and this product is certainly no exception.

Editor’s Rating:


  • Minimum/Maximum Pressure: 800 PSI – 3,200 PSI
  • Flow Rate: 1.4 to 5.3 GPM
  • Fill Capacity: 33oz


This foam cannon comes with all of the regular structural attachments and settings. A tough and durable brass connector keeps water pressure in check while the adjustable nozzle allows you to change foam density in the blink of an eye.

The real crowning achievement of this foam cannon is the absolutely tough and hardy design it is crafted with. Not only is this constructed out of high-grade plastic, but it also comes with an extra-wide neck attachment which is rarely seen in foam cannon designs. This is a game-changer, in a sense, because it forces the foam cannon to disperse total pressure outwards, keeping this weak area from breaking under pressure, which can happen with some models. This ultimately makes the TriNova foam cannon the ultimate buy for someone looking for an option with longevity.


Unfortunately, the wider and tougher neck design comes with a price. The TriNova foam cannon requires you to own a pressure washer that is at least in the 1000 PSI range to start with. Another issue is that this product doesn’t come with its own connector out of the box, so you’re going to have to make that purchase separately. This definitely isn’t a “one-stop-shop” sort of product.

However, if you already have a pressure washer of that caliber, or your wallet can handle purchasing one, this is easily the best premium option on this list. Its durability will last you for many years to come without fail.


  • Durable construction
  • Can work with lower water pressure than other models
  • Adjustable flow rate


  • Doesn't come with connectors
  • Requires at least a 1000 PSI pressure washer

7. Best Beginner’s Package: Chemical Guys Foam Cannon and Soap Kit

Chemical Guys Foam Cannon and Soap Kit

Why we like it: This stunning foam cannon package comes with three different kinds of car soap for a variety unlike any other.

Editor’s Rating:


  • Minimum/Maximum Pressure: 800 PSI – 3,500 PSI
  • Flow Rate: 1.4 to 5.3 GPM
  • Fill Capacity: 32oz


The Chemical Guys are a well-known brand in the realm of car care. They are definitely one of the most popular brands out there and their reputation is impeccable. Their TORQ series foam cannon is no joke and takes a worthy spot on our list of the very best foam cannons on the market today.

Let’s discuss the foam cannon portion of this grab bag first, though. This bad boy comes with strong brass connectors on top of a high-quality plastic bottle enclosure that doesn’t wear down over time from harsh UV rays, which can cause cracks to appear on plastic products over time.

One of the most interesting design qualities of this product, however, is its (patent pending) Threadlock System. This is, essentially, a sleeve that is designed to keep brass threads from tearing up external plastic soap bottles over a long period of time while also providing a tight, effective seal. This not only keeps degradation over a long period of use to a minimum but also serves its purpose in producing the absolute best foam production that money can buy.

The TORQ foam cannon also comes with an air-injection system that helps to conjure up thicker suds via the Chemical Guys’ unique mechanism. This system, in fact, is able to create tons of frothy soap on as little as 800 PSI, making it an ideal choice for lower-powered pressure washer devices.

The awe-inspiring power of this package doesn’t stop there, though. On top of the high-quality foam cannon, this kit also comes with two different car soaps to sample as well as a bottle of glossy cleaner for that extra shine.


The most obvious downside we could find is the 32oz capacity, which is one ounce lower than all of the other foam cannons on this list. It’s not too big of a deal, but it’s a noticeable change. Overall, this is a killer package, and if you’ve got the cash to spare, it’s an excellent introduction to the world of foam cannons.


  • Incredible soon-to-be patented Threadlock System
  • It’s a great foam cannon starter kit
  • Tough, UV-resistant bottle construction
  • Air-injection tech makes for a very powerful spray


  • 32oz instead of 33oz
  • Expensive

8. Most Durable Pick: SudMagic Foam Cannon

SudMagic Foam Cannon

Why we like it: This foam cannon has an extremely tough threaded design and hardcore stainless steel interior that will keep it usable practically forever.

Editor’s Rating:


  • Minimum/Maximum Pressure: 1000 PSI – 3200 PSI
  • Flow Rate: 2.0 – 5.3 GPM
  • Fill Capacity: 33oz


Made out of professional-grade HDPE plastic, this bottle is made tough! On top of that, the threads of the bottle itself are made out of brass, which ultimately means it won’t wear down much like plastic-threaded bottles have a tendency to do, especially when left out exposed to the sun’s harsh rays.

When you include all of that on top of a stainless steel filter design, which keeps this foam cannon practically from ever rotting away due to rust and harsh corrosion from humid environments, this is quite literally a Frankenstein’s monster of all the foam cannons on this list.


The only real problem we found with this product is that it’s not to be used with heavy-duty pressure washers that go beyond 3000 PSI. However, it won’t work well on pressure washers under 1000 PSI, so keep that in mind prior to purchasing. All in all, this is a solidly-made product that can practically last you forever due to its incredibly durable design. While it’s not the cheapest option on this list, it’s longevity potential is certainly worth the extra dollars.


  • Brass-constructed threads
  • Stainless steel filter keeps rust at bay
  • Tough brass connectors
  • Can work with both gas as well as electric pressure washers
  • Lifetime Warranty


  • A bit more expensive than other models on this list
  • Needs at least a 1000 PSI pressure washer to work properly

9. Most Accessories: Scuddles Foam Cannon

Scuddles Foam Cannon

Why we like it: This impressive package deal comes with a lot of fantastic accessories to get you cleaning your car efficiently in no time.

Editor’s Rating:


  • Minimum/Maximum Pressure: 1000 PSI – 3000 PSI
  • Flow Rate: 2.0 GPM
  • Fill Capacity: 34oz


This impressive foam cannon starter kit comes with a massive amount of accessories to give you pretty much everything you need to start up high-octane weekend car wash madness. This package comes with a high-quality foam cannon complete with five different nozzles that can be utilized for many different cleaning situations. Everything from a zero degree nozzle for the toughest of dirt stains all the way to a 65-degree nozzle for lightly spraying a wide layer of detergent over your car.

The foam cannon itself comes with all of the usual features. Durable brass fittings and a huge 34oz plastic bottle made of durable plastic. The extra-large bottle is great for those lazy day wash sessions where you just absolutely have to get every inch of your car as clean as possible.

To even out the kit, it also comes with three microfiber towels for fast wipedowns, a fairly large foam sponge, and an attachable gun that can connect to your pressure washer hose that allows for greater control over the foam cannon itself.


Based on our findings, the Scuddles foam cannon’s fittings can sometimes not tighten properly, which can cause water to spray out from the fitting section. This obviously is a fairly strong negative and affects its score. However, that being said, the company offers a full refund on the product if you aren’t satisfied at all.


  • Comes with an incredible amount of accessories
  • Large 34oz bottle
  • Made in the USA
  • Full refund if not satisfied


  • The connective fitting could use some work

10. Best Basic Pick: Blisstime Foam Cannon

Blisstime Foam Cannon

Why we like it: The Blisstime foam cannon is a simple, affordable piece of equipment that comes with a great microfiber pad for a deeper clean.

Editor’s Rating:


  • Minimum/Maximum Pressure: 1000 PSI – 3000 PSI
  • Flow Rate: 2.0 GPM
  • Fill Capacity: 33oz


This foam cannon is similar to many of the others on this list. It’s made from tough, durable plastics and comes complete with brass connectors. This means you’ll get a tight fit for the maximum pressure output needed to wash your vehicle with ease.

In some cases, opaque bottle design on foam cannons can make seeing just where your soap/water levels are at a bit of a hassle at times. Even stellar products like the MATCC Adjustable Foam Cannon can suffer from this problem. This is not the case with the Blisstime foam cannon. In fact, not only does it have a wonderful see-through design, but it also comes complete with various measure marks on the bottle, which are great to have for accurate dilution of car soaps.

To round out the package, this foam cannon comes with its own microfiber towel to touch up harder to clean spots during the cleaning process, which we found a very nice touch.


We noticed that sometimes this product didn’t connect properly with the pressure washer, causing a certain amount of leaking in the process, so your mileage may vary depending on your particular pressure washer. Also, due to this connection issue, it can potentially break easily as well.

With the price taken into consideration, this is a safe purchase for someone who is a bit hesitant to see if they even desire a foam cannon in the first place. But with the quality control issues in place, we had to place it very last on this list.


  • See-through bottle design
  • Microfiber cleaner included
  • Brass connectors
  • Measure marks on the bottle for diluting purposes
  • Inexpensive


  • Quality issues

Complete Guide to Buying the Best Foam Cannon

Here are some more in-depth points that expand a bit more on what we originally covered in our brief buyer’s guide earlier in the article. If you’re still a bit fuzzy on some aspects of owning a foam cannon, we think this section will help inform your purchase tremendously.

Perks of Owning a Foam Cannon

We’ve talked quite a bit about the kinds of foam cannons worth purchasing, but you might be asking why owning one is a good thing in the first place? Here are a few key reasons to sink your teeth into.

They Are More Environmentally Friendly

Foam cannons get their water source directly from a pressure washer (usually) and then mixes said water in a bottle with some form of soapy admixture. This whole process drastically cuts down on water loss, which is not only good for the environment but also good for your water bill as well! Comparatively speaking, the old-fashioned approach with soap and a rag will have you dumping out excess unused water, which is a big waste of resources in the long run.

They Keep You From Wasting Time

We all know the old-school way of washing a car… in fact, you probably had to do it for your folks as a kid at some point! It’s not fun and takes a lot of elbow grease to wash off all of the grease and grime that accumulates on all vehicles over time. A foam cannon can help reduce the overall time you spend on washing your car tremendously. Not only that, but it’s also way more efficient since it can hit all of those hard to reach areas that are generally difficult if not outright impossible to clean with the standard soap and a rag sort of setup.

They Are Convenient

When you’re finished washing your vehicle, all you have to do as far as cleanup is store your pressure washer wherever you keep it with the foam cannon already attached to it, ideally with the soapy concentrate already in the bottle ready for next time’s usage. Simple, fast, and efficient.

They Keep You From Ruining Your Paint Job

Foam cannons absolutely coat your entire car with gloriously thick layers of foam and fast. This is not only a great thing in terms of saving time, but it also means that you won’t mess up your car’s paint job trying to scrub and scrape off all vestiges of dirt on the car’s exterior. Foam cannons are adept at removing all forms of dirt on your vehicle’s exterior smoothly.

They Are Multi-Purpose

Foam cannons are best known for washing vehicles, but did you know they can be used for many other areas of life as well? You can use a foam cannon to blast your decks, porches, gutters, dirty outdoor furnishings, driveways and much more. Foam cannons can even clean RVs and boats effectively as well.

Foam Cannons and Foam Guns: What Gives?

This article has been specifically focused on foam cannons, but we’re also aware that sometimes people will confuse these with foam guns as well, so we’re here to set the record straight on this small bit of confusion.

A foam cannon will usually work with a pressure washer. However, foam guns always work in tandem with a regular hose system.

Foam cannons give a higher volume of foam than a foam gun can manage, giving them an edge when it comes to automobile cleaning equipment. Some individuals, however, either don’t want to invest in a pressure washer or are hesitant to use one thinking that it might scratch up their car’s paint job. In this case, we would definitely think a foam gun might be a better choice.

How to Use a Foam Cannon

Foam cannons are easy as well as fun to use. Here’s a small primer on the matter.

  1. Unscrew the foam cannon’s container and fill it up with a decent mix of car soap and water. Be sure to check your car soap’s instructions for the proper levels of soap/water if you’re not certain.
  2. Give your car a decent once over with your pressure washer or garden hose to remove the most visible sources of dirt prior to the foaming process.
  3. Once this is finished, go ahead and attach the foam cannon to the pressure washer.
  4. Proceed to spray thick layers of foam all over your vehicle. Let it sit for a few minutes before proceeding to step 5.
  5. Rinse your vehicle off thoroughly after most of the soap suds drop from the vehicle.
  6. Slough off any large amounts of water off your vehicle, and allow it to dry. This keeps water spots from manifesting on the surface of your vehicle.

For the visual learners reading this article, here’s a fantastic and in-depth video on how to best use a foam cannon.

Helpful Foam Cannon Tips

  • Be sure to let the foam sit on your car for a good couple of minutes before rinsing it off. At least ten minutes is a good metric to start with, but it really depends on just how filthy your car is.
  • Make sure you use your foam cannon in a dry, sunny area, preferably on a day that isn’t very humid. A nice, moderately warm period in the sun will dry your vehicle off faster than spraying it down in a shady garage area.
  • Don’t leave any foam on the vehicle whatsoever. This is terrible for paint jobs and can leave nasty spots all over your vehicle that are difficult to remove when they dry.
  • Make sure the soap and water ratio is accurate depending on the brand of car soap you’re using. This is important because it makes sure that you can get the maximum dirt-cleansing power out of your blend.


Are Foam Cannons Brand-Specific When It Comes to the Soap Used in It?

No, foam cannons are designed to be versatile with all brands of car foaming soap. Be aware that some brands of car soap may be more diluted than others, but for the most part that has nothing to do with your particular model of foam cannon.

Do I Need to Invest in a Professional-Grade Foam Cannon?

If you are a freelance detailer, then we would strongly encourage purchasing a professional-grade foam cannon for a few reasons. For one, you’re going to want to invest in a proper piece of equipment that is durable and isn’t going to wear down fast over a long period of time. If you desire such durability, look towards purchasing a foam cannon with brass fittings, as they are the standard when it comes to durability in these sorts of items. Something that has adjustable output settings for foam would also be desirable for someone looking for a professional-grade foam cannon.

If you’re just an average Joe looking to clean your car with relative ease, however, then you certainly don’t need to worry about going full professional-grade quality with your foam cannon purchase. Most folks don’t wash their car daily, and because of that, you won’t have to worry about most well-made foam cannon products breaking down from overuse any time soon. This doesn’t mean you should skimp on overall quality, but it also means that you don’t absolutely have to buy the most expensive foam cannon model either.

Are Foam Cannons Worth Purchasing?

Well, we’d have to give a resounding “yes” to this one. While it’s true that a foam cannon isn’t necessary to wash one’s vehicle, the benefits of owning one outweigh the negatives of not owning one in the first place.

Probably the biggest thing you have to bite as a consumer is that most foam cannons require you to own a pressure washer already. Pressure washers can be expensive and not everyone can afford such a piece of equipment nor do they have room for such a thing. However, we definitely think that owning both a pressure washer and a foam cannon are great additions to your car care arsenal.

Will Most Foam Cannons Fit on My Garden Hose?

It really depends on the model, but most foam cannons are not designed with garden hose use in mind. Some foam cannons have adaption kits that allow them to be retrofitted to a backyard garden hose, but it’s certainly not the standard.

Can I Use My Foam Cannon for Other Things Besides Washing My Car?

Absolutely! As we said earlier in this buyer’s guide, a foam cannon can be used to clean dirty driveways, patio areas, outdoor furniture, and much more. If it can be sprayed off with your basic backyard garden hose, it can also benefit from the foam cannon treatment.

The Best Foam Cannons Make Car-Cleaning Simple

We hope these product reviews have been helpful in determining the best choice for you and your vehicle cleaning needs. Foam cannons aren’t really a necessity when it comes to cleaning your car, but they can sure help expedite the process. After all, who wants to use up more of their precious time on the weekend dedicated to… more work? Don’t do that to yourself, especially if you’re a real car enthusiast and you want your ride to look as great as it possibly can.

If you didn’t see a product on our list that really stood out for you, or if you’re still a bit on the fence about the exact kind of purchase you need to make, please take another look at our short buyer’s guide as well as our more in-depth extended buyer’s guide for a closer look at all the details you’ll need to make an informed purchase for a quality foam cannon.
