If we want our cars to look good, we have to keep them clean. We all know it of course, but sometimes we just don’t want to acknowledge it. After all, as much as we love our cars, do we really want to be out there day after day with buckets and sponges and rags?
No, of course we don’t – so thank God someone invented the foam cannon. This amazing product makes deep cleaning the outside of your car a breeze. Not only does it make the whole job faster and easier – it can often have far better cleaning powers than you and bucket or a plain garden hose could possibly achieve.
Naturally, such a useful and popular device has a number of manufacturers, all putting out models with different advantages – so we’re here to help you pick the best foam cannon on the market.
The Best Foam Cannon
This product brings two very important features to the table that makes it easy to recommend. First off it has brass connectors, which means it is easy to achieve a tight connection to your pressure washer. This is great because you don’t want to waste any of the awesome water pressure – it is the pressure after all that really helps a foam cannon to do its job.
Secondly you get a great 33 ounce bottle to contain your liquid foam pre mix. That should be an ample amount to easily clean a normal sized vehicle several times over before you need a refill.
One complaint would be that the bottle itself is quite opaque. That can make it hard to easily monitor the amount of foam liquid mix you actually have left. Aside from that though it’s hard to fault this item – especially given it’s very competitive price.

This is another quality spray that won’t break the bank – though it does come in a tad more expensive than the model we discussed above.Brass connectors, another excellent 33 ounce sized bottle and all round solid construction again make this quite a similar product overall. However it differs in having a greater range of adjustability in its foam lance core – i.e. the amount and concentration of spray of pressurized foam it produces.
This gives this model a degree of flexibility to tackle a number of additional jobs around the home – not just cleaning your car! It can be used for window cleaning, getting driveways back to their best – the cleaning applications are endless.
Once again the opaque nature of the bottle construction is a bit of a pain – but at this price you’ll be able to live with it.

The first thing that most people notice about this offering from Chemical Brothers is that it comes as a set. That is certainly worth taking note off because if there is one company who know what they are doing with auto cleaning products it is the excellent Chemical Brothers.
So if you go for this set you get two bottles of high – foaming cleaner solution plus a high gloss shampoo. You can use them in conjunction or individually, they all do a great job – and one of them even has a great citrus smell if you want your car to be sparkling clean & smell like a giant lemon!
You also get a premium Foam Cannon in this kit that has a great brass connectors, a big (and see through!) plastic mix bottle and a unique design that incorporates a cutting edge air injection system for super powerful spray and outstanding formula mixing. This kit isn’t cheap, that’s true – but it really is a premium product that is well worth the investment.

This is the kind of product that simply does exactly what it is supposed to do. There are no shiny extras or bolted on features – this is a well made, sturdy cannon that will give plenty of top quality use over a prolonged period.
This is certainly a product that the manufacturer is happy to allow to stand more on what it can do than on what it promises to do. It doesn’t even have a logo on it! Instead, this product comes equipped with excellent quality brass connectors that don’t lose pressure, a nice big bottle to hold plenty of foam mix and an easily adjustable spray nozzle for accurate mixing and superb foam spray.
This is a quiet little product with no thrills – but don’t let that put you off picking up what is actually a really well made tool that will do a great job.

If you live in an area where your vehicle gets especially dusty or muddy then you should certainly consider this model of cannon. By coming with the pressure washer trigger built in, DUSICHIN have created a product with strong connectors and a comfortable, ergonomic handle.
In practice, that means that this cannon can handle water pressure of up to 3,000 psi. Combine that with the ergonomic handle and you have a product that is a delight to use for longer periods. That means that this product can generate incredibly powerful water and foam jets that can cut through serious grime like dust and mud with no problems at all – and you can easily and comfortably hold it for long periods.
So if you’re looking for a powerful model to handle the dirtiest jobs with ease, this could well be the model for you.

This well made cannon comes with everything you need to clean your car quickly and easily.
The brass connectors hold water pressure well so you’re not wasting any – this cuts down on time and also water use, since all the water is spraying on the car and not onto your driveway! The connected bottle is a generous 33 ounces and it is translucent – that makes it easy to keep an eye on the amount of foam mix you have left during the clean.
It’s a really well put together, sturdy piece of kit too that should last a while. And – AND! – you get a free cleaning cloth. What’s not to like?
Translucent Bottle (33 Ounce)
Free Wash Mitt
- Weight1.35 Pounds
This is a premium item constructed to exacting standards – but then you should expect nothing less from a company like TriNova.
This cannon is built with functionality and durability built in. Functionality – the brass connector is a top quality and designed to keep all the water pressure exactly where you need it – inside the cannon. The nozzle is easy to adjust so you can change the foam mix and density easily on the fly.
Durability wise this item is made with lovely think plastic that is going to last a while. It has also been designed with an extra wide neck attachment – something of a unique feature. This area can be a weak point on some models due to the high-pressure build up pushing against this relatively small and weak area. Not a problem with this model, that wide neck is designed to spread the pressure out and prolong the product lifespan. It’s not the cheapest model out there, but as a long-term investment it certainly makes sense.

Best Foam Cannon Buying Guide & FAQ
That is our pick of the best foam cannons on the market – and I think you’ll agree that is a pretty good selection.
But how to choose the best model for you – and once you have got your very own cannon, how to use it to its best advantage?
Foam Gun vs Foam Cannon – What’s the Difference?
You may have heard some people talking Foam Guns, and of course, we’re here talking about Foam Cannons – so you may well be asking yourself just what is the difference?
Well, for one thing, the biggest clue is in the name – we’re talking about a gun versus a Cannon!
The essential difference is that a Foam Gun plugs into your hose. So it’s a simpler machine to use, no doubt about that. However, it also means that:
- Its effectiveness is limited by the water pressure coming out of your hose, which can often be poor, to say the least.
- It actually uses more water than a cannon, because more low-pressure water is required to do the same job as less water that has a higher pressure.
- It just doesn’t work that well in all honesty. The foam that the gun makes is usually a pretty weak sheet that runs off quickly without doing much cleaning at all.
On the other hand, a Foam Cannon has to work in conjunction with a pressure washer. This naturally makes it that much more complicated than the simple gun. You need a pressure washer for one thing, and you also need the kind of high-quality brass connectors that can attach it to the pressure washer properly (don’t worry, all the models we selected above have high-quality connectors at standard).
This extra effort does, however, bring some serious benefits, such as:
- High-Pressure water combines with foam to provide an outstanding clean. Seriously, if you want your car to look like it has been professionally cleaned and detailed, then a foam cannon is key to getting that premium finish – and getting it faster than by hand.
- It uses less water by being more efficient with what it is using. This could be an important consideration if you live in an area (or a building like an apartment complex) that has water use restrictions.
- It’s a very efficient way to clean your car. Look, we love our cars, and sometimes it’s great to be out in the sunshine with a bucket of suds and cool beer and take your time cleaning out every grill and carefully wiping down the windshield and getting everything looking great. Other times it’s cold, the game starts in an hour, you’re tired and the car is filthy. In those instances, a foam cannon and a good quality pressure washer can really be your best friends!
Tips When Using a Foam Cannon
This is a good start because for once we’ll be beginning with something you don’t have to do! That’s a nice change of pace, right?
The first thing you can do is forget about bothering with a pre-wash – which flies in the face of a lot of car washing guides.
The thing is though you have a secret weapon that they don’t – a foam cannon. The point of a prewash is to remove any hard specks of dirt and debris. These little bits can get caught in your sponge or cloth whilst hand washing and can scratch or whirl the paintwork.
The beauty of a cannon, however, is that you are essentially washing “hands off.” So you don’t have to worry about a pre-wash, just get on with cleaning. This is really one of the main reasons why these products can be such time savers.
What else do you need to do to get the most of these products? Well, you should.
Wait for sunshine – You wouldn’t wash your car with buckets in the rain, so don’t bother with your cannon either. This may seem straightforward, but we’ve seen enough people out there in the rain it’s worth pointing out!
It’s all about the foam – You have bought this product to take advantage of the best way to spray foam – so make sure you are doing just that! All these tools come with adjustable nozzles to help you regulate the amount of water that is mixing with the foam product. You want a nice stream that produces a thick foam that easily clings to the outside of the vehicle. Watch the Statue of Liberty scene from Ghostbusters 2 to get a good idea of what we’re talking about here.
Clean off – what goes on, must come off! Either disconnect the cannon from your pressure washer or move the adjuster nozzle so that no foam mixture is going into the water stream. Work the water jet from the top of the car and work toward the bottom. Don’t do it the other way round, or you’ll just blast dirt up onto the car from the ground.
Finish off – You should now have a nice clean car. Leave it as it is, or dry it off and apply your usual wax (highly recommended).
Things to Consider Before Choosing your Foam Cannon
So what factors should you bear in mind when picking out your cannon? Well, to our mind these are some of the most important ones:
Connectors – This is actually one of the most important considerations. A poor connector will both a) let water pressure escape, rendering the tool-less efficient, and b) break easily. All the models we selected come with brass connectors that are the best on the market – run a mile from any tool that comes with a plastic connector!
Versatility – it’s handy if it can be used for other purposes like cleaning concrete driveways or patios. But at the end of the day, these tools are not very expensive (around $20 is the average) and they are designed for cars.
Transparent Bottle – A pet peeve of mine (you may have noticed in the product guide!) but transparent bottles are a little easier to use. You can just easily see how much foam mix is left, instead of trying to guess.
Solid Build – It’s worth noting that these items are going to have a relatively tough life. For example, the water pressure they have to handle is pretty exacting, so you want a tool that is well made and built to last. The connector is one of the weak points on these tools so again by selecting models that come with brass connectors, you know that if you choose one from this list it is a durable model built to last.
Capacity – You don’t want to be stopping to refill the foam mix bottle every 5 minutes! With some models you are, because the bottle they come equipped with is simply too small to function properly. We’ve stopped you having to worry about that by only choosing tools with nice, big 30 Ounce or bigger bottles. That should give you plenty of foam mix to easily clean a large car or truck in one go.
Good luck with whatever model you go for and remember to have fun in the foam!
