AstroAI Foam Cannon, Wide Neck, 1L Bottle

Works really well and makes thick foam that covers the car evenly. The material feels sturdy and well made, and the bottle holds a good amount of soap.

What the seller says

  • Built for Pressure Washers, Not Garden Hoses: This foam cannon is designed for pressure washer systems rated 1000–3000 PSI and features a 1/4" quick connect fitting for fast setup with most compatible wands. An easy upgrade for car wash sprayer accessories. Please check your connector size before purchase; NOT compatible with any garden hoses, faucets.
  • Thick Foam Lifts Dirt Before You Scrub: Cover your vehicle in deep-cleansing foam that loosens tough grime, dust, and mud from paint, wheel wells, and tight crevices. This cleaning tool gets the job done without directly rubbing on your automobile's finish. Ditch the manual scrubbing, save time, and keep your car's paint intact.
  • Adjustable Foam Output and 360° Spray Output: Fine-tune your clean with the top foam control knob and rotating nozzle. Turn the knob towards "-" to increase the detergent in the mixture for thicker foam. Then, rotate the sprayer nozzle to control the spray direction for doors, hoods, bumpers, windows, wheels, sidings, and more. Control your cleaning modes with a light snow foam to a thick lather.
  • 1L Wide-Mouth Bottle with Durable Brass and Metal Parts: This large 1L bottle holds plenty of soap solution for full vehicle coverage, while the wide opening reduces spilling while filling and mixing cleaner. The brass valve and sturdy metal fittings add durability for repeated weekend washes. For better results, use high-quality foaming soap and avoid wax-based formulas that may clog the internal
  • Versatile Cleaning for Cars and Home Surfaces: It's more than a car wash tool; this pressure washer foam cannon works great for motorcycles, bikes, trucks, and outdoor surfaces like driveways, patios, siding, windows, and floors. After each wash, rinse with clean water, dry, and store in a cool, ventilated place to help prevent soap buildup, corrosion, and clogging before your next detailing job.
