McKillans Foam Cannon for Pressure Washer — Wide-Mouth Snow Foam Lance, Adjustable Foam & Brass Connectors

McKillans Foam Cannon (wide mouth) is a pressure-washer soap lance that produces dense, adjustable snow foam for gentler, more effective vehicle washes.

This foam cannon pairs with most electric or gas pressure washers to create thick, clingy foam that loosens dirt and adds lubricity during rinsing and mitt washing. Its wide-mouth bottle simplifies mixing and filling, and the brass and stainless connectors are built to resist pressure and leaks. The unit offers an adjustable spray angle and foam thickness control so you can tailor output for vehicles, wheels, or exterior surfaces.

How does the wide mouth improve mixing and handling?

The larger bottle opening makes pouring concentrated soaps and adding water faster and neater, reducing spills and mess. The broader base also gives the bottle a more stable stance while you set the cannon down, preventing tip-overs during a job.

• Wide mouth allows easier soap dilution and measuring.
• Translucent bottle shows remaining solution at a glance.
• Stable, wider base reduces the chance of falling over.

What controls let me change foam thickness and spray pattern?

A top-mounted control knob adjusts the foam output from light coverage to dense snow foam, and the nozzle angle is adjustable to widen or narrow the fan. These two settings let you switch quickly between pre-soaking the whole vehicle and targeting stubborn grime on wheels or lower panels.

• Knob for precise foam volume control.
• Adjustable nozzle angle to alter spray width.
• Works across flow rates from small electric units to larger gas washers.

Are the fittings and bottle durable enough for regular use?

The foam cannon uses brass and copper fittings rather than lower-grade plated metals, improving longevity under pressure. The bottle is molded from strong translucent plastic so you can inspect chemical levels and avoid unexpected runouts during a wash.

• Solid brass connectors resist wear and pressure-related leaks.
• Stainless quick-connect design for reliable attachment and release.
• Thick, translucent plastic bottle for strength and visibility.

What cleaning results can I expect compared to a standard spray?

Dense foam clings to paint and dissolves surface grime, helping to lift dirt before contact washing and reducing the chance of creating swirls. While foam alone doesn’t replace mechanical action, it makes rinsing and mitt washing safer and more effective by lubricating the surface.

• Clingy foam loosens road film and light contaminants.
• Extra lubrication reduces friction during contact washing.
• Better coverage speeds pre-wash and decreases repeated passes.

If you frequently pre-soak vehicles, clean heavily soiled wheels, or prefer a spill-free filling experience, this foam cannon is designed to improve wash speed and reduce paint contact wear. A one-year residential warranty provides added confidence for at-home use.

• Includes 1/4" stainless quick connector compatible with common pressure washer fittings.
• Recommended for use with diluted car shampoo or dedicated snow-foam solutions.
• Avoid using highly corrosive chemicals to preserve seals and fittings.
