8 Benefits of Using a Foam Cannon vs. Hand Washing

When it comes to washing your car, there are a few different ways that you can go about it. You can either hand wash it or use a foam cannon. While both methods will clean your car, there are a few benefits that come with using a foam cannon instead of hand washing. Here are 8benefits of using a foam cannon vs. hand washing:

You’ll Save Time

One of the biggest benefits of using a foam cannon is that it will save you time. For example, when you hand wash your car, you must spend a lot of time scrubbing it to ensure that all dirt and grime are removed. With a foam cannon, you can spray the foam on and let it do its job.

You’ll Use Less Water

Another benefit of using a foam cannon is that you’ll use less water. For example, when you hand wash your car, you have to use a lot of water to ensure that all dirt and grime are removed. You use less water with a foam cannon; you use less water because the foam does most of the work.

Easier lubrication for removing dirt

The foam from the cannon will act as a lubricant to help remove dirt from your car. It is especially helpful if your car has a lot of dirt and grime build-up.

You Can Reach Hard Reach Areas

Another benefit of using a foam cannon is reaching hard-to-reach areas. For example, you can only reach so far when you hand wash your car. You can spray the foam into hard-to-reach areas with a foam cannon and get your car cleaner.

Reduced risk of scratching paintwork

When using a foam cannon, you don’t have to worry about scratching your paintwork. The foam from the cannon will act as a buffer between your car and the wash mitt, reducing the risk of scratching.

Creates a slick surface to easily wash the dirt away

The slick surface created by the foam helps to easily wash dirt and grime away without scrubbing. That is one of the reasons why foam cannons are so popular among car wash professionals.

Foam cannons help to preserve your car’s paint

By not having to scrub your car’s paint, you can help to preserve it. That is especially important if you have a newer car with fresh paint.

It’s More Fun

Washing your car with a foam cannon is just more fun. It’s a great way to relax and have fun while cleaning your car. Plus, it’s a great way to show off your car to your friends.

So, a few benefits of using a foam cannon vs. hand washing exist.

Types of Foam Cannon

Foam cannons have two simple types –

  1. Adjustable
  2. Non-adjustable. 

The adjustable ones let you decide the thickness of the foam and the spray pattern. All the cannons mentioned above have this feature.

Non-adjustable ones do not let you control those things, which is a drawback for those cannons.

And it’s certainly better to choose the adjustable foam cannons.

How to Choose the Best Foam Cannon for your needs

Foam cannons are not the most complicated piece of tool. On the contrary, they’re pretty straightforward, and it’s all about the foam it produces. But then again, if it were that simple, you wouldn’t be reading this guide on foam cannon reviews.

You need to remember quite a few things to find your perfect foam cannon. Here it goes –


One of the crucial considerations. A poor connector will make you suffer – it will let the water pressure escape and leak and break after a while. That’s why choosing a cannon with a suitable connector is crucial.

All the cannons suggested above have connectors made of brass, which is the ideal material for connectors. They ensure a firm connection, last long, and avoid any corrosion. DO NOT even think about the cannons with plastic connectors.

Also, care about the configuration of the connector. For example, does it support ¼” quick connect?


You want your cannon to let you decide how the foam should look. I mean the thickness of the foam and the spraying pattern as well. You often need to switch between the more thick and less thick foam.

For instance, more dirty places like your wheel wells may require more foam, whereas less foam will do in places the paintwork. Deciding the thickness of the foam for a particular area helps you use your Soap more efficiently. There’s usually a simple knob that lets you determine the thickness by a simple twist.

Along with the dilution of the Soap, the ability to adjust the spraying pattern helps too. A fan spray will do fine in some places, like the body. However, you want a jet spray to clean that area better, utilizing the water pressure in some areas. Make sure your cannon allows you to do that with an adjustable nozzle.

Versatility & Pressure Washer Requirement

The foam cannons we are talking about are primarily for a car wash. But their usage possibilities do not end there. These cannons can be used for other tasks, like cleaning windows or driveways. So if you find a cannon that takes care of those tasks, that’s a great bonus for you.

And before you buy a foam cannon, make sure its minimum requirements match the specification of your pressure washer (PSI & GPM). Otherwise, it won’t be able to perform to its full potential.

The Bottle

When it comes to the foam cannon bottles, there are three things you need to look for – 


 You’ll be working with your cannon outside, where it is expected to have long exposure to sunlight. And the bottle has to withstand tremendous water pressure at the same time. Thus, cannons need to be sturdy.

You can judge by the thickness and feel of the plastic when it’s in your hand. But when it’s not, you have to rely on foam cannon reviews by the other users. So check out the foam and what other users say about the durability of the plastic of that model.

If you’re still unsure, I can assure you that the models I’ve mentioned above have well-built bottles built to last.


You don’t want to stop and refill multiple times during a wash; that’d be annoying. That’s why pick a bottle with enough cleaning fluid holding capacity to get you through a session quickly.

All the models mentioned above have a holding capacity of 1 liter or more which will be more than enough.


 It’s better to see how much cleaning fluid is left rather than guessing. A transparent bottle will help with that.

10 Best Foam Cannon Reviews

Here are my top picks for foam cannons! I have reviewed each of these below. I had to create this article because there are so many options! I have used them all, and I have known friends who are also manufacturers.

The goal is to provide honest reviews, comparisons, and recommendations to find the best foam cannon for your needs. I also include direct links to Amazon to see what others say about the products.

Dusichin Foam Cannon – Best Foam Cannon Under $20

Last update on 2024-06-30 / Affiliate links / Images from Amazon Product Advertising API

The Dusichin Foam Cannon is our number 1 pick for the list of best foam cannons. The reason is that it does what many expensive soap cannons can’t do, yet it’s very competitively priced.

Do not let it fool you by the price; it offers much better performance than what it costs.

It’s a heavy-duty soap cannon with a capacity of 33 oz (1 liter), which can fit enough solution to cover at least five cars with foam. The ¼” quick disconnect adapter lets you connect and disconnect frequently.

The connectors are high-quality brass for longevity and a firm connection with the pressure washer.

You’re in the driver’s seat with the Dusichin Foam Cannon in hand. You get to control how thick you want the foam layer to be. There’s a soap mixture knob that lets you choose whether it will be more water & fewer foam bubbles or less water & more foam bubbles.

Not only that, but the adjustable spray nozzle also lets you pick the pattern you want: water column pattern or fan pattern. All the control is in your hand when you have the Dusichin Foam Cannon.

This cannon requires your pressure washer to have over 1000 PSI pressure and 1.2 GPM; keep that in mind.


  • It allows for a wide range of customizations.
  • Quick disconnect adapter.
  • Durable.
  • Competitively priced, fantastic value for money.


  • Tend not to pull Soap in a few cases.

Twinkle Star Foam Cannon

Last update on 2024-07-07 / Affiliate links / Images from Amazon Product Advertising API

The twinkle star foam cannon is identical to the Dusichin foam cannon: inexpensive yet great.

The twinkle star cannon has a capacity of 33 oz too. You can say this is the standard capacity of most foam cannons. You get the ¼” quick-disconnect adapter to connect and disconnect easily.

The connectors again are made of brass for a firm connection. The bottle is made of high-quality see-through PA that will not break soon.

However, this model has a few positive changes. It offers you more adjustability than the Dusichin model. It comes with an additional five nozzle tips that allow you to spray at 0°, 15°, 25°, 40°, and Soap-degree patterns.

It makes this cannon suitable for versatile uses. You can foam wash other things, too, with this cannon.

The soap mixture knob lets you decide the thickness of the foam you want. The cannon can disperse thick foam up to 20 feet after getting the pressure washer’s correct water pressure.

That said, a pressure washer with 1000 PSI pressure and 2.5 GPM is needed for this cannon to perform best.


  • Five adjustable nozzle tips.
  • Versatile usage possibilities.
  • Value for money.


  • The male connector sometimes seems to have challenges connecting with the Pressure Washer.

TriNova Foam Cannon – Best For Under $40

Last update on 2024-06-30 / Affiliate links / Images from Amazon Product Advertising API

TriNova’s foam cannon is my third pick for the best foam cannon for pressure washers.

The manufacturer claims their foam cannon is more premium than other cheap cannons, and I can’t entirely agree with them. Admittedly, their foam cannon cost a little more than cheaper cannons, but I think it’s worth it.

When we talk about premium products, it’s always the small things that are well taken care of in them. Those little details create a difference in user experience.

Take the TriNova cannon, for example. Do you hate when your cannon keeps tipping over with the slightest unconscious push or a gentle breeze? I do.

Barely any other manufacturer took such a little thing into concern, but TriNova took it seriously. As a result, they’ve redesigned their cannon and made them more comprehensive in the base – problem solved. A minor fix but a more significant relief for the user is what premium products are all about.

Not only the base, but they’ve included a wide neck too. A common problem with foam cannons is a broken neck because the most pressure is applied. That issue is addressed in the TriNova foam cannon with a broader and firmer neck.

Not only that, but this cannon also works excellent with any psi pressure washer. Other cannons require pressure washers with a minimum mentioned psi to work correctly, but this one does not. And it’s pretty easy to use as well.

The premiums are felt on the bottle too. However, it’s made of excellent materials, so feels sturdy and promises not to break any soon.


  • Broader base & neck.
  • It is made out of premium material all over.
  • It’s suitable for washers of any PSI.


  • It costs little more than generic foam cannons.

MATCC Adjustable Foam Cannon

Another value-for-money product on my list is the MATCC adjustable foam cannon. Again quite a similar product to the first two cannons that I recommended – inexpensive and does what it’s supposed to do.

This one is a 1-liter cannon that does not need to be filled fully to do your sedan or SUV. The ¼ quick connection is there for convenience. However, you want to check your machine before purchasing because not every garden hose fits.

The connectors are made of high-quality brass that makes for rustproofing and durability. The bottle seemed pretty well-made too. Well, not the best it feels, but neither the worst.

The adjustable soap mixing knob is in its position to let you decide the thickness of the foam by controlling the ratio of water & Soap. The adjustable nozzle lets you choose the spray pattern: cylindrical or fan. Just the standard stuff you expect in a foam cannon, nothing groundbreaking.

This cannon will be a good fit for other deep cleaning tasks too. For example, you might wash your motorbike, floor, windows, roof, driveway, and whatnot. Note that this cannon requires a washer with 2.0 GPM & 1000 PSI pressure to work correctly.


  • High-quality brass.
  • Suitable for all sorts of deep cleaning.
  • It offers you the adjustability you expect.


  • The bottle tends to tip over, a little imbalanced.

Tool Daily Foam Cannon

Last update on 2024-07-17 / Affiliate links / Images from Amazon Product Advertising API

The Tool Daily’s foam cannon offers what we all desire – premiums at a low cost. I’m not sure how this brand does it, but their cannon does feel more premium than I expected for its price. Oh, by the way, the cannon costs similar to as much as most other ‘inexpensive’ cannons.

Except for the bottle, all other things on this cannon are brass, and it feels great. The plastic of the bottle felt sturdy too. As far as build quality is concerned, this foam cannon from ‘tool daily’ certainly punches above its weight.

And that is probably the reason why this cannon can withstand 4000 psi with ease. Washing with this cannon when you have a high-power electric or gas pressure washer isn’t a problem thus. Instead, the capability of withstanding high pressure will make it easy to wash with this cannon.

It is a 1L soap cannon that comes in a see-through bottle. The standard ¼ quick connect plug is present there.

Another surprising thing about this cannon is the five extra nozzles within the package. The nozzle pack includes 0° (red), 15°(yellow), 25°(green), 40°(white), and 65° (black) nozzles. The 65° one is brass, while the others are stainless steel. The extra nozzle pack is as high-quality as the cannon.

This wide range of nozzles makes this cannon versatile. You can either have a strong jet spray from that 0° nozzle for stubborn dirt, a wide fan spray from the 65° nozzle, or anything in between with the other nozzles. It makes for various uses of the cannon.


  • Premiums in the budget.
  • Five extra nozzles make it suitable for various uses.
  • High-quality brass.


  • The nozzles tend to wear out upon being used in hard water

Chemical Guys Professional Foam Cannon

Last update on 2024-06-30 / Affiliate links / Images from Amazon Product Advertising API

If you have some extra cash to spill and want something great in return, I can recommend the TORQ EQP 313 professional-grade foam cannon.

This product costs way more than most other mainstream soap cannons, but there’s a reason why so many people have bought it and overwhelmed it with positive reviews. This cannon is considered one of the best foam cannons for electric pressure washers.

This bad boy features the industry-first thread lock insulation system, which is a very own piece of tech from Chemical Guys. This mechanism helps prevent the bottle from wear and tear, a common problem for mainstream soap cannons.

Not only that, but this tech also helps create the perfect airtight seal between the TORQ body and the soap canister. Thus, a great blend of air pressure, Soap, and high-pressure water is maintained to produce the richest foam.

It features an advanced air injection system that ensures an adequate oxygen supply to create the thickest foam. And, with all the tech in place, this cannon produces the thickest and richest foam.

The overall package is made from the finest material that you could expect in a soap cannon. The corrosion-resistant brass is there to last till eternity. The UV-resistant bottle ensures that the neck won’t crack no matter how long you keep it under the sun.

And the cannon is forgiving when it comes to your pressure washer, as it works with pressure washers of any PSIs.


  • Innovative tech in place.
  • Made out of the finest material.
  • It produces the thickest foam.


  • Expensive.

Fasmov Foam Cannon

Last update on 2024-07-07 / Affiliate links / Images from Amazon Product Advertising API

After an expensive suggestion, here’s another value king for you. The Fasmov foam cannon has overwhelmed its users with its performance against their expectations from such an affordable cannon.

I’ve recommended quite a few similar products priced in the budget range but work great, yet I couldn’t avoid Fasmov’s cannon. This cannon is terrific at producing a crazy volume of foam from a limited amount of Soap.

It looks like just another affordable soap cannon out there and has the standard features like the 1/4″ Quick Disconnect Adapter, Brass-connectors, 1-liter container bottle, and so forth.

The freedom to control the suction of cleaning fluid stays there. And you can still adjust the spray angle by adjusting the nozzle.

This build quality is on par, not bad nor excellent. Built out of decent plastic, it will serve you for a fair amount of time.

Overwhelmed users of this cannon claim that it performs like a 50$ cannon in terms of volume and foam thickness, and I think I agree with them.


  • It produces a lot of foam for a minimum amount of Soap.
  • It features all the standards.
  • Inexpensive yet works terrific.


  • Build quality is not the best I’ve seen.

McKillans Professional Grade Foam Cannon

Last update on 2024-06-30 / Affiliate links / Images from Amazon Product Advertising API

If you want to spend something between the price of a premium cannon and a budget cannon, you’re in for a treat. The McKillans foam cannon is excellent for people with a low GPM pressure washer.

Just like Fasmov’s foam cannon, it produces foam that you expect from a more expensive cannon. But the better news is that the quality issue has been taken care of very well in this unit from McKillans.

If I want to categorize it with similar cannons, this will fall in place with the TriNova’s cannon. Both the cannons work quite similarly as well.

It’s a semi-premium foam cannon with performance and builds quality close to a premium model. This standard foam cannon has all the standard features you’d expect.

However, this cannon separates itself from the build quality it offers for the money. This cannon is expected to last years, made out of thick and translucent solid plastic. The high-quality brass easily withstands high water pressure.


  • It works great with pressure washers of low GPM.
  • It produces nice & thick foam.
  • Better-built for the money.


  • The bottle thread tends to leak air sometimes.

Chemical Guys Torq Foam Wash Gun

Last update on 2024-07-18 / Affiliate links / Images from Amazon Product Advertising API

No pressure washer? No problem, when you have the ACC 326 Torq foam wash gun in hand. When you don’t own a pressure washer but still want to give your car a foam bath, this is what you need, a foam wash gun.

This gun works with any standard garden hose. However, do not expect such a powerful jet spray as a pressure washer provides. But that doesn’t matter that much anyway.

All that matters is covering your car with a thick layer of foam, and the ACC 326 foam wash gun gets that job done nicely. Next, you must connect your hose with the gun and pull the trigger to start foaming.

The gun can hold 32 ounces of cleaning liquid at once. Chemical Guys do not compromise on build quality since they’re known as a premium brand, and the 326 is no different, made of translucent solid plastic.

You can still control the concentration of the foam with the knob to match the degree of dirtiness of your car.


  • Works without a pressure washer.
  • It helps to prevent swirl marks with lubrication.
  • Good build quality.


  • It does not produce as thick foam as a cannon that works with a pressure washer.

Blisstime Snow Foam Cannon

Last update on 2024-06-30 / Affiliate links / Images from Amazon Product Advertising API

Last but not least, the Blisstime Snow Foam Cannon sum up the list of best foam cannon. It is another inexpensive standard cannon that is great at doing its job.

It has got the standard 1-liter cleaning fluid holding capacity. The bottle is made of suitable quality plastic, and it feels sturdy. However, it’s not the most well-built bottle, so do not put it through too much stress.

The connectors are made of high-quality shiny brass, though. It felt premium and looked terrific.

The adjustability features are there. You can also control the foam’s concentration and the spraying pattern. The cannon burst out of thick and delicate foam.

The standout thing is that it includes a microfiber car wash mitt as a gift. It is a great bonus and saves you some bucks – a tremendous complimentary gift to serve its original purpose in the best manner: cleaning your car.


  • It produces thick and delicate foam.
  • It comes with a car wash mitt.
  • Inexpensive.


  • It does not produce thick suds when pressure washer recommendations are not met.

Foam Gun vs. Foam Cannon - Which is better?

It depends. A foam cannon is the better option when you have a pressure washer. However, when you don’t have one, you have no other choice but to get the job done with a foam gun.

Foam guns and foam cannons are designed for the same purpose. But a foam cannon requires a pressure washer to operate. In contrast, a foam gun works with a simple garden hose.

But foam guns do not produce as thicker foam as a foam cannon. It’s because foam cannons are backed by excellent water pressure from the pressure washer. But foam guns only get the standard water pressure from the hose.

So foam cannons are the best choice when you have a pressure washer. A foam gun will do the job when you don’t have one, just not as well as a cannon. 

You’ll need more time to cover your vehicle with foam, and that won’t be as thick and nice as a foam cannon would do.

Best Foam Gun Garden Hose Foamer Attachment

If you don’t have a pressure washer, this foam gun will give you a decent thick foam layer before washing your car. It’s similar to a foam cannon, except instead of as much water pressure, you’ll need less.

How to use a foam cannon properly?

Foam cannons are pretty straightforward tools to use. That’s why you clean your car with a foam cannon – 

Step 1: Do a pre-wash or rinse

Doing a pre-water wash helps you eliminate any looser, heavier, and more abrasive grime, debris, and dirt. Otherwise, these little bits can scratch or whirl your car’s paint during hand or cloth wash.

When you do a pre-wash, the ideal practice is to start from the top and work your way down. It will ensure you do not re-introduce dirt to a place you’ve already cleaned.

Step 2: Put Soap into your cannon

Put a few ounces of your favorite car wash soap into the cannon and fill the rest with water. Mix the solution well. Make sure you tighten the bottle properly; otherwise, there will be air leaks, and it won’t work correctly.

Step 3: Connect the Cannon with the Pressure Washer

After that, connect your cannon with your pressure washer wand or lance. Make sure the connections are firm; otherwise, it’ll leak.

Step 4: Adjust your cannon and start spraying

Adjust the soap mixing knob to determine the dilution of the Soap. When you want more foam and less water, twist the knob clockwise, and do the opposite for the other case.

Tip: When foaming areas with more stubborn dirt, apply thick foam.

Also, adjust the spray pattern of the cannon. If you want more reach, keep the nozzle at a more vertical angle, reducing the foam’s spread area. Keep the nozzle at a more horizontal angle when you want the foam to spread more.

After making the adjustments, pull the trigger, and start foaming. Again, start from the top and work your way down. 

Step 5: Rinse it off

After you’re done with foaming, give it a moment to emulsify any dirt. Then you can rinse it off with your pressure washer. Again start watering from the top to work your way down.

Step 6: Dry your car

When you’re done, dry your car off to remove all the water and apply your favorite wax to bring the shine to your car.

Top 5 Foam Cannon Tips And Tricks

Tip 1: Use The Right Pressure Washer

Your foam cannon will only be as good as the pressure washer you use. So if you want thick foam that clings to your car and gets it clean, you need a pressure washer to deliver those results.

A gas pressure washer will typically offer more PSI and GPM than an electric one, which means it will do a better job at Foam Cannon.

On the other hand, electric pressure washers are often quieter, smaller, and easier to move around.

So ultimately, the best foam cannon is the one that works with the pressure washer you have.

Tip 2: Use The Right Soap

Not all car soaps are created equal. To get thick, clinging foam from your foam cannon, you need to use a specifically designed soap. A good car soap will have a high foaming action and be thick enough to cling to your car.

Moreover, it is important to use a car soap that is pH balanced, which is important because using a soap that is too alkaline or too acidic can strip away waxes and protective coatings from your car. On the other hand, a pH-balanced soap will be gentle on your paint and help preserve the life of your waxes and coatings.

Tip 3: Dilute With Warm Water

Warm water will help thin out the soap and make it easier for your foam cannon to create thick, clinging foam. Add a few gallons of warm water to your pressure washer tank and mix the soap according to the manufacturer’s instructions.
Do not use hot water as this can damage the seals on your pressure washer pump.

Tip 4: Rinse Your Car Before You Start Foaming

It is important to rinse your car before you start foaming it to remove any loose dirt and debris that could potentially scratch your paint.

Moreover, rinsing your car before you foam will help to ensure that the foam clings to the dirt and grime on your car and not to the paint itself.

Rinse your car with a pressure washer using just water before you start foaming.

Tip 5: Maintain Your Foam Cannon

Like all tools, your foam cannon will require some maintenance from time to time. Be sure to clean your foam cannon after each use.

Rinse it with water and then store it in a cool, dry place. Besides, follow the maintenance tips below.

Maintaining your foam cannon

Though Foam Cannons are simple tools, they still need some maintenance to function correctly. Here’s what you need to do to maintain your foam cannon – 

  1. Detach the sprayer from the bottle. 
  2. Put some warm water into the bottle, shake it slightly to clean the inside, and remove any leftovers.
  3. Take any cleaner, even a glass cleaner. Spray some on the outside of the bottle and wipe with a towel.
  4. Spray some on the foam cannon sprayer, and let it sit for a bit.
  5. Wipe that off with the towel, attach the sprayer to your bottle, and you’re suitable for your next car wash.

3 Best Pressure Washers to Attach Your Foam Cannon

Wrap Up - Best Foam Cannon Reviews

If you’ve been with me till now, I believe you’ll have no problem picking the perfect foam cannon for your needs. As I said, foam cannons are not the most complicated tool to decide between options, so don’t stress out much.

The best overall cannon would be the TriNova Foam CannonThis model is highly functional, looks premium, has got innovative touches like a wider neck and base, and does not cost a hundred dollars.

The other cannons are great too, but for me, this cannon stands at the sweet point of not too cheap, neither too expensive, just pure functionality and premiums at a moderate price.

Oh, and, no matter whatever cannon you purchase, remember to have fun with the foam.

Frequently Asked Questions

I often get asked these questions. So let’s settle this once and for all.

Does GPM matter when using a foam cannon?

Yes, it matters. A foam cannon will perform to the fullest when its’ required pressure washer GPM is met. If it’s not fully met, it’ll still function but not to its’ fullest potential.

Will a foam cannon fit onto my garden hose?

No, it won’t be functional anymore.

Can I use regular Soap in a foam cannon?

It is not recommended. Liquid car wash soaps have a specific dilution ratio for this task and are the better fit here. That’s why you should not put a bucket car washing type of Soap in a cannon.

Do you put water in a foam cannon?

You do. There’ll be a mix of Soap and water to create a cleaning solution.

Can you use a foam cannon without a pressure washer?


Can you put bleach in a foam cannon?

Not recommended and not necessary either.

How much PSI do you need for a foam cannon?

It depends on the specific cannon. It will mention the required pressure. A pressure washer with 800-1000 psi will primarily help.

Do All Foam Cannons Work With All Pressure Washers?

It is a common misconception that you need a powerful pressure washer to use a foam cannon. It is not the case! A foam cannon will still work even if you use a less powerful pressure washer. The main thing that you need to pay attention to is the nozzle size.

Make sure that the nozzle size on your pressure washer matches the nozzle size on the foam cannon. Other than that, it’s just a matter of setting the appropriate amount of water flow and soap concentration.

What Soap do you use in a foam cannon?

Any of your favorite liquid car wash soap can work. However, if you want to know which Soap is the best for foam cannons, we have this article together for you.

Can I use a different car wash soap brand than the foam cannon I purchased?

Absolutely. You can do that.

My foam cannon only works when I hold it upside down. What’s wrong?

Maybe your pressure washer isn’t supplying enough pressure. Try another washer to see if it’s the fault of the cannon or the pressure washer.

The foam cannon moves around a lot when connected to the pressure washer. What’s wrong?

Try keeping it disconnected after use.
