THICK FOAM. EVERY ANGLE OF EVERY VEHICLE.A 360° spray angle means you can operate this cannon in any orientation — pointed up at the roof, sideways under the rocker, straight down at the lower body, even fully inverted under a wheel arch — without losing foam density, pressure, or prime. Combined with a thick, slow-falling foam profile that clings to vertical panels for full dwell time, this cannon delivers maximum surfactant contact across every panel in a single pass. The way pre-wash foam was supposed to work. NO SPILLS. SHAKE IT. TILT IT. INVERT IT.Conventional foam cannons start dribbling product the moment you tilt them past 45° — soap on your hose, soap on your driveway, soap running down your arm. This cannon's internal check-valve seals the reservoir the instant you release the trigger. Hold it sideways. Flip it upside down. Set it on its side on the workbench. The foam stays in the bottle until you ask for it. NICKEL-PLATED BRASS. HERE'S WHY THAT MATTERS.Bare copper oxidizes. Surfactants, alkaline soaps, and hard water all convert exposed copper into verdigris over time — the green patina you've seen on old plumbing — and once it forms, it can shed into whatever passes through. That's a known property of the material, and it's why we didn't build this cannon around it.The internals here are machined from solid brass and electroplated in nickel: the same corrosion-resistant finish used in marine hardware, professional plumbing, and electrical contacts. The brass core gives strength and thermal stability; the nickel plating gives a hard, chemically inert surface that won't oxidize, won't shed, and won't tint your foam. FAN OR JET. ONE TWIST OF THE NOZZLE.A single twist switches between a wide 70° fan for full-panel coverage and a focused jet for heavy soiling, lower body, and wheel wells. No swapping nozzles, no separate attachments, no fittings to lose in the garage. One cannon. Two patterns. Selected on the fly. 1L CAPACITY. WIDE MOUTH. WIDE BASE.A full liter of capacity covers a full vehicle wash with no mid-wash refills, even at heavy foam settings. The wide mouth fills without a funnel — pour LATHER straight from the bottle. The wide base sits flat on a tailgate, workbench, or driveway and stays put. Engineered for how you actually use it, not how it looks on the shelf. 1/4" QUICK CONNECT. FITS MOST HOME PRESSURE WASHERS.The standard 1/4" quick-connect fitting snaps onto most consumer pressure washers, including common units from Karcher, Ryobi, Sun Joe, Greenworks, and AR Blue Clean. Rated for pressure washers up to 4000 PSI. Detail Labs isn't affiliated with or endorsed by any of those manufacturers — check your unit's pressure and flow ratings and fitting size before connecting. PRESSURIZED EQUIPMENT. TREAT IT LIKE IT.This is a pressure tool, not a spray bottle. Never exceed the 4000 PSI rating. Wear eye protection. Never point it at a person or animal — pressurized spray can cause serious injection injuries that don't look serious at first. Inspect the fittings, seals, and quick-connect before every use, release pressure before disconnecting, and use it only with a dedicated automotive foaming shampoo — never solvents, acids, bleach, or corrosives. Rinse and drain after every use, and store it empty and protected from freezing. Frequently asked questions Will it fit my pressure washer? The standard 1/4" quick-connect fits most consumer pressure washers up to 4000 PSI, including common Karcher, Ryobi, Sun Joe, Greenworks, and AR Blue Clean units. Confirm your unit's fitting size and pressure rating first — configurations vary and modified units aren't covered. What soap should I use in it? A dedicated foaming shampoo like LATHER. Pour it straight into the wide-mouth reservoir — no funnel needed. Never run solvents, acids, bleach, or corrosive chemicals through it. Does it spill if I tilt it? No — 360° pickup and an internal check-valve mean you can tilt or fully invert it without dribbling product. Guides & how-tos Foam Cannon vs Foam Gun: What's the Difference?
