Verdict: Choose a foam gun if you wash from a garden hose and own no pressure washer. Choose a foam cannon if you already own a pressure washer with M22 14mm or 1/4 inch fittings and want a bottle you can see into.
On a Saturday wash day, thick suds make the job feel lighter, and the foam cannon vs foam gun question comes down to what feeds it: a garden hose or a pressure washer. Both spray foam, but they connect differently, control foam differently, and suit different driveways. This comparison covers the differences, then one example of each from the listings we reviewed.

Raincovo Foam Cannon for Pressure Washer with Stainless Steel Filter
A clear foam cannon for pressure washers with a stainless steel filter, an adjustable nozzle and a 1L bottle.

Read the full review
The Raincovo example is a pressure washer foam cannon: a 1L clear bottle, a stainless steel filter, an adjustable nozzle that rotates to any angle, and M22 14mm or 1/4 inch quick connect fittings, with an additional 1.1 mm orifice nozzle for working pressure below 1500psi. Its size is 10 x 6 x 3 inches.
Pros
- 1L clear bottle shows how much soap is left
- M22 14mm and 1/4 inch quick connect fit most pressure washers
- Stainless steel filter resists corrosion and acid and alkali
- Additional 1.1 mm orifice nozzle for working pressure below 1500psi
Cons
- Needs a pressure washer, unlike a garden hose gun
- Weight is not stated
- Warranty is not stated
- Needs rinsing after each use and indoor storage
Chemical Guys TORQ Foam Blaster 6 Garden Hose Foam Gun
A garden hose foam gun with an adjustable foam ratio dial that sprays thick suds with no pressure washer.
Who it's for: owners who wash cars, wheels, glass and trim from a garden hose and own no pressure washer.
Who should skip it: anyone who wants a pressure washer cannon with a bottle and fittings the listing states.
Read the full review
The TORQ example plays the foam gun side: it attaches to a standard garden hose and needs no pressure washer, with a foam ratio dial that runs from light rinse to thick suds. Its size is 9.09 x 5.51 x 5.39 inches and it weighs 1.35 pounds. Note the naming split: the title calls it a cannon while the bullets call it a foam gun and a foam wash gun; this article follows the bullets and the hose fitting, since a cannon in this comparison needs a pressure washer.
Pros
- Works with a standard garden hose, no pressure washer needed
- Adjustable foam ratio dial from light rinse to thick suds
- Thick suds encapsulate dirt and grime for cars, wheels, glass and trim
- Connects with no additional tools or machines stated
Cons
- Bottle size is not stated
- Pressure washer compatibility is not stated
- Warranty is not stated
- No filter or nozzle detail is stated

Foam cannon vs foam gun side by side
| Factor | Foam gun (TORQ Foam Blaster 6) | Foam cannon (Raincovo) | Stated by |
|---|---|---|---|
| Water source | Standard garden hose, no pressure washer | Pressure washer with M22 14mm or 1/4 inch quick connect | Both listings |
| Foam control | Adjustable foam ratio dial | Regulator knob, adjustable nozzle, additional 1.1 mm orifice nozzle | Both listings |
| Bottle | Not stated | 1L clear bottle | Cannon listing |

| Washes | Cars, wheels, glass and trim | Cars, patio furniture and other items | Both listings |
Figures are manufacturer stated for the two example models, collected 25 October 2026.
Water source: garden hose or pressure washer
Water source is the line between the two sides. A foam gun runs off a standard garden hose with no pressure washer, so it suits a driveway where the hose is the only water feed. A foam cannon needs a pressure washer, so it suits a property that already stores one with matching fittings. The Raincovo cannon example lists M22 14mm or 1/4 inch quick connect fittings, while the TORQ gun example lists a standard garden hose connection and states that no pressure washer is required. See pressure washer versus power washer for the machine side of the choice.
That difference also decides setup. The gun example connects with no additional tools or machines stated, while the cannon example connects to a pressure washer and needs its fittings to match. If your fittings do not match, check before ordering.
Foam control: dial, knob or nozzle
Both examples let the user change foam thickness, but the controls differ. The TORQ gun example uses a foam ratio dial that runs from light rinse to thick suds. The Raincovo cannon example uses a regulator knob for foam thickness plus an adjustable nozzle that rotates to any angle and controls spray pattern, with an additional 1.1 mm orifice nozzle that produces more foam when the working pressure is below 1500psi. Neither listing states a pressure figure for the gun side, so the two sides cannot be compared on pressure, and this article does not call either side stronger on that measure.
What each one can wash
Use overlaps more than water source does. The TORQ gun example lists cars, wheels, glass and trim, with thick suds that encapsulate dirt and grime. The Raincovo cannon example lists cars and patio furniture among other items, with a 1L bottle the listing states is large enough to cover thick foam on an entire car’s surface. A gun suits a car wash from the hose; a cannon suits a car wash plus patio furniture and other items from a pressure washer, provided the fittings match.
Handling and size
Size and upkeep separate the examples further. The TORQ gun example measures 9.09 x 5.51 x 5.39 inches and weighs 1.35 pounds, while the Raincovo cannon example measures 10 x 6 x 3 inches with its weight not stated. The cannon example adds a clear bottle, so the soap level stays visible, plus a wide mouth for pouring soap and water without spilling. Its listing also gives a care rule the gun listing does not: rinse it thoroughly with clean water after each use, and store it indoors away from sunlight. See pressure washer types when matching a cannon to a machine.
The two examples
Matching It to Your Property
- A garden hose gun fits a driveway wash area where the only water source is a standard garden hose.
- A pressure washer cannon fits a property that already stores a pressure washer with M22 14mm or 1/4 inch fittings.
- A clear 1L bottle suits washing a whole car in one fill, since the cannon listing states the bottle covers thick foam on an entire car’s surface.
- Store the cannon indoors away from sunlight after rinsing, since its listing gives that care instruction.
The Acre Score explained
The Acre Score weighs performance, build, value, safety and warranty. Neither example states a safety feature or a warranty term, so both score 0 on those two measures, and the ranking rests on performance, build and value from stated specs. The cannon example leads on stated detail: fittings, filter, bottle and orifice are all listed. The gun example follows closely on a simpler promise it states clearly: foam from a garden hose with no pressure washer. How we pick explains the weights.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Raincovo Foam Cannon | 9.6 | 29 | 21 | 20 | n/a | 0 |
| TORQ Foam Blaster 6 | 9.6 | 28 | 20 | 21 | n/a | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
Never point the spray at people, animals or yourself: the stream can cut skin. Run gas pressure washers outdoors only, far from doors, windows and vents, because engine exhaust carries carbon monoxide. Start with the widest nozzle and keep electric units on a GFCI outlet. Refuel only with the engine off and cool. See CPSC carbon monoxide guidance. Read our Safety Disclaimer.
FAQ: mowing large lots
Do I need a pressure washer for a foam gun?
No. The TORQ gun example works with a standard garden hose and states that no pressure washer is required. The Raincovo cannon example is the one that needs a pressure washer.
Which fittings does the foam cannon example use?
M22 14mm or 1/4 inch quick connect fittings, with an additional 1.1 mm orifice nozzle for working pressure below 1500psi.
Can I see how much soap is left?
With the Raincovo cannon example, yes: its bottle is clear, so the soap level stays visible. The TORQ gun example states no bottle detail, so its soap level is not stated.
How do I look after a foam cannon?
The Raincovo listing states the rule: rinse it thoroughly with clean water after each use, and store it indoors away from sunlight. The TORQ gun listing states no care rule.
