Raincovo Foam Cannon Wide Mouth for Pressure Washer, Snow Pro

Why it's worth it

The Raincovo pairs a smaller 1.1mm orifice with a wide-mouth bottle and tool-free nozzle swaps. It squeezes more foam out of a modest electric pressure washer than most cannons in its class, and it costs a fraction of what the MTM does.

Most cannons are tuned for gas washers pushing 2.0 GPM or more. The Raincovo isn't. Its 1.1mm orifice is tighter than the 1.25mm standard, which builds more foam density out of less water — exactly the problem electric pressure washer owners keep running into. If your machine sits below 1,500 PSI, this is the smarter buy.

The nozzle unscrews by hand, which is a bigger deal than it sounds. Fixed-pin designs on cheap cannons mean a clogged orifice is a dead cannon. Here you back the nozzle out, rinse it, and put it back. Owners also swap orifice sizes to match their washer — a few report moving up to a wider orifice on a strong machine and getting even better results.

What we like

• +Most cannons are tuned for gas washers pushing 2.0 GPM or more
• +The nozzle unscrews by hand, which is a bigger deal than it sounds
• +The bottle is see-through with measurement gradations molded in, so you can mix a consistent ratio without guessing
• +Value is the real argument

What to know

• –The cap and bottle connection is the weak point, and it's not a rare complaint
• –It's also a newer name without the long track record MTM Hydro or Chemical Guys have, so there's less accumulated evidence about…
