Foam Cannon

Foam Cannon — Thick Foam, Zero Hassle

Transform your wash routine with the Otto Guys Foam Cannon — engineered to deliver rich, clinging foam that lifts dirt safely and makes every wash faster, easier, and more satisfying.

Built with a wide‑mouth 1‑litre (33 oz) bottle, brass hardware and stainless steel 1/4" quick‑disconnect fitting, this cannon pairs perfectly with any pressure washer to create a true foam‑party experience.

Why You’ll Love It

• Ultra‑Thick Foam: Produces dense, shaving‑cream‑like suds that cling to paint and help lift dirt without scratching.
• Wide‑Mouth Bottle: Easy to fill, easy to clean, and stable when mixing your solution.
• Premium Build: Durable plastic bottle + brass nozzle for long‑lasting performance.
• Fully Adjustable: Control both foam output and spray pattern to dial in the perfect wash.
• Quick‑Disconnect Ready: stainless steel 1/4" quick disconnect makes swapping attachments effortless.

How to Use

1. Fill the bottle with 600 ml of warm water (warm water boosts suds).
2. Add 60 ml of your favourite shampoo — we recommend Otto Guys Pure Wash for maximum foam.
3. Attach the bottle, swirl gently to mix, and connect to your pressure washer.
4. Adjust the top dial and spray pattern to your liking, then enjoy the foam show.

Care Instructions

After washing, run clean water through the cannon to flush out soap and keep internals performing at their best.
