Sun Joe Foam Cannon for Electric Pressure Washers 34 oz — 1/4" Quick Connector, Adjustable Spray & Detergent Dial

The Sun Joe SPX-FC34-MXT is a 34-ounce foam cannon attachment that turns most electric pressure washers into a thick snow-foam applicator for faster, touch-free cleaning.

If you want to load soap onto cars, trucks, boats, siding, or outdoor equipment with a dense, clingy foam layer, this foam cannon gives you precise control over spray pattern and detergent mix. It fits most pressure washers up to 3000 PSI and pairs especially well with Sun Joe detergents. Lightweight and easy to fill, it streamlines pre-wash and detail routines without swapping tools or complicated setup.

How does this foam cannon improve vehicle and surface cleaning?

The cannon aerates detergent into a viscous foam that clings to surfaces, helping to loosen dirt and road grime before rinsing. That reduces scrubbing time and minimizes the risk of swirl marks compared with aggressive hand scrubbing. Foam coverage also makes it easier to spot missed areas.

• Creates a thick, clingy lather that breaks down dirt and grease.
• Even coverage speeds up pre-wash and reduces manual abrasion.
• Adjustable soap dial lets you match foam strength to task and detergent.

What pressure washers and detergents work with the SPX-FC34-MXT?

The SPX-FC34-MXT connects via a 1/4" quick-disconnect fitting and is compatible with most pressure washers rated up to 3000 PSI. It’s optimized for Sun Joe snow foams and pressure-washer soaps, but it functions with many mainstream cleaners—just follow detergent dilution guidelines.

• 1/4" quick connector for fast attachment to common pressure washer wands.
• Works with washers up to 3000 PSI; check your machine’s outlet and fittings.
• Marked fluid ounce and milliliter measurements for precise mixing.

How do you adjust spray pattern and foam thickness?

Tune the spray from a pinpoint jet to a wide fan by turning the nozzle head; this changes coverage and cleaning force. A detergent dial on top controls the soap-to-water ratio—turn toward (+) for more foam and toward (–) for less. The included quick-connect nozzle tips offer different spray angles for specific tasks.

• Adjustable nozzle: jet to fan spray for targeted or broad coverage.
• Detergent dial: precise control over foam concentration.
• Five quick-connect tips (0°, 15°, 25°, 40°, soap) for varied cleaning needs.

What are the size, weight, and build details I should know?

The foam cannon holds 34 fluid ounces—large enough for multiple vehicle passes but compact to remain portable. It’s lightweight at roughly one pound so it won’t tire your wrist during use. Clear measurement markings on the bottle make mixing repeatable and accurate.

• 34 fl oz capacity with ounce and milliliter markings for exact mixes.
• Lightweight construction (~1 lb) for easy handling and transport.
• Durable housing and quick-connect hardware designed for regular outdoor use.
