Washing your car on a hot summer day can be taxing or relaxing, depending on your perspective. But swapping out your bucket of suds for a foam cannon or foam gun can make it both easier and more fun. If you’re not an intense, perfectionist detailer and just want the job done quickly, it’ll also help speed up the process.

Foam cannons and guns combine powered or unpowered water pressure with soap to quickly create a thick coat of sudsy foam, and the impact of the blasting helps loosen and remove dirt and debris without the manual scrubbing as a traditional soaping process. The foam is also thicker, and more evenly dispersed, than what you can apply with a regular washing mitt. This generally produces a cleaner car with less effort, which in concert with post-washing products can help prolong the life of your car’s finish.

But not all Foam cannons and foam guns are the same, and which one you choose depends on the additional equipment you have at home and your workspace. Foam cannons usually attach to pressure washers, whereas the foam gun connects directly to a standard garden hose. Foam cannons typically require a 2 GPM (gallons per minute) flow rate, a minimum force of 1,000 PSI (pounds per square inch) and a maximum PSI of 3,000 to work properly.

For our list of the best foam cannons, we’ve included a broad selection of both cannons and foam guns based on the most widely available examples on the market from known and trusted brands. These products were reviewed on material durability, ease of use, cleaning performance, liquid capacity and cost.

With its friendly price tag, the one-liter Scuddles Foam Cannon definitely provides the best bang for the buck on the market. The difference from similar products is in the materials and the accessories. With brass fittings and other high-quality parts, this cannon should last through many a power wash. The Scuddles comes with five spray nozzles of varying degrees to meet every cleaning challenge, and it offers an array of spray settings. That said, some users do report a bit of leakage at the nozzle over time, and this cannon isn’t compatible with all pressure washers, so check fitment before purchase. A large foam sponge and microfiber washcloths are also included.

An easy-to-use gun for the first-time foamer, SwiftJet’s Car Wash Foam Gun Sprayer blends air and soap with water from your garden hose to create a thick coating foam solution. The canister holds up to one liter of soap, and there are six varying spray options whereas most competitors offer five or fewer. These range from full foam for extra dirty vehicles to a minimal setting that’s mostly water for final rinsing. The ratios are controlled by a helpful dial. Brass components and a PVC bottle make for durable hardware, but some users have reported that the foam nozzle can blow off if not properly installed. The SwiftJet also comes with a microfiber wash mitt, for when the gun just can’t get the grime off without a helping hand.

If you’re washing a dual-axle,  crew-cab, long-bed Ford Super Duty, you might need a little more soap than you’d use on a Toyota MR2, and for that the Adam’s Premium Foam Gun is a natural. With a soap canister capacity of 35 ounces, it’s one of the largest-capacity guns on the market, so if you have no pressure washer and have big jobs ahead, it’s a good option. Extra soap means a longer duration of foaming and having to refill three-quarters of the way through the job. There are four foam blend settings and a setting which widens the sprayer for better coverage. Stainless steel fittings should also mean long service life.

Since it costs just $45, the Chemical Guys Torq Foam Blaster 6 is a real bargain. Chemical Guys has a long reputation for making quality washing products at competitive prices and this is no exception. With up to 32 ounces of capacity, it’s big enough for fairly large and tough jobs but is still meant to attach to an ordinary garden hose. Its friendly price does mean some tradeoffs, however. There’s a precision spray handle with an adjustable foam dial, although it doesn’t have as many settings as some other competitors and produces thinner, weaker foam dispersion than some pricier guns. The materials are also a little cheaper, and some users report leaks at the nozzle over time. At the price, however, it’s hard not to be satisfied, and the Torq Foam Blaster 6 is the top seller on Amazon’s Car Washing Nozzles & Hose Attachments list.

At less than $20, this tiny foam cannon bottle is a bargain for folks who already have a pressure washer with a quarter-inch connector, a 2 GPM flow rate and 1,000 PSI of pressure. At that price it’s hard to go wrong, but the Foseal does not include a high-pressure water gun or the adapter needed to attach it to the cannon. Once it is connected, there’s a simple knob on top that controls the foam dispersion. It isn’t the most precise setup but most users acclimate to it pretty quickly. Customers also widely praise the Foseal product for its high-quality, brass construction. The company has clearly prioritized construction rather than extras, so if you already have the extras, this is a great deal.

The Chemical Guys’ Torq Snubby Easy Trigger Foam Cannon Attachment is actually only part of a cannon, but it offers very fine washing control and professional-grade capability when coupled with a foam canister and a pressure washer. Only the grip and cannon actuator are included here, but the Snubby also comes with the various adapters required to connect to separate foam cannon canisters and different types of pressure washers. The grip is light, but when coupled with the other parts needed to make it work it can be a little heavy, though it keeps the foam canister very close to your hand for precise control. Built to last, the Snubby is a heavy-duty product that can handle a max force of 5,000 PSI and a flow rate of 10.5 GPM, which is comparable to more expensive professional products.
