The Raincovo Foam Cannon Kit with Short Gun and Dual-Connector Lance is a foam cannon kit sold by Raincovo on Amazon under ASIN B0DRVRRGXJ. The model number on the listing is FMGW6. Everything on this page is read off that listing — the specification table, the bullets and the photographs are Raincovo's own, and the comparisons are against the rest of Raincovo's range rather than against a marketing claim.

Specification

Straight from the Amazon listing's own attribute table. Fields the seller has clearly filled in wrong — a "hose length" of one inch on a brass fitting — are dropped rather than reprinted.

What Raincovo says it does

These are the manufacturer's own claims, quoted from the listing.

Pro-level Setup: Pressure washer soap attachment combines a foam cannon (thick, paint-safe suds), dual-connector lance (simultaneous soaping/rinsing), and short gun (precision control) for professional-grade home cleaning. Five nozzle tips with holder for versatile applications.

Unique Design

Dual connector lance makes it very easy to accomplish car detail. The valve slides smoothly to achieve two modes, not leak. Just foam and rinse with one hand and use a wash mitt with the other, all done in one step. A whole new dimension to your washing!

Foam Performance

Foam cannon isn't just limited to car washing, it excels at cleaning windows and tackling grime on various outdoor surfaces. Upgraded stainless steel filter prevents clogging for consistent foam flow. Replace with 1.1 mm orifice nozzle (included), it will produce more foam when the working pressure is below 1500psi.

Grime Eraser

Clear foam cannon has a really cool look. No more guessing how much soap inside and when it's empty. 1L bottle is large enough to cover thick foam on entire car's surface, which remove dirt, grime, and other contaminants. Don't have to scrub and risk scratching or damaging the paint.

Lightweight / Maneuverable

Short pressure washer gun is more flexible compared to the long wand, which reaches tight spaces effortlessly. It's ideal for thorough cleaning wheels to remove dirt and stubborn stains. It's much easier to handle and store. Compatible with M22-14mm pressure washer hose. For hoses with M22-15mm or 3/8" quick connect, an additional adapter is required.

Note

This product is designed exclusively for pressure washer hoses and cannot be used with garden hoses, water hoses, or faucets.

How it compares with Raincovo's other foam cannons

With 4.0★ from 111 ratings, 1 of Raincovo's 7 foam cannons with at least twenty ratings score higher: Snow Clear Foam Cannon.

How it connects

It fits with a 1/4-inch quick-connect plug — the same size as the colour-coded nozzle tips that come with most pressure washers. If your gun or wand takes those tips, the cannon clicks straight on in their place.

If your gun ends in a threaded M22 fitting instead (common on electric washers), you need an M22-to-1/4-inch adapter between the two: M22 14mm to 1/4" Quick Connect Fittings.

The listing also names M22 14mm compatibility, so a gun with a 14 mm M22 thread can take it directly.

It needs a pressure washer. The listing says in so many words that it does not work on a garden hose or a tap: foam cannons rely on the pressure-washer's flow to pull soap through the orifice.

Raincovo's listings do not name the pressure washer brands they fit — Ryobi, Sun Joe, Greenworks and the rest are not mentioned. What decides fit is the connector on your gun, wand or pump. The Raincovo Foam Cannon Parts, Bottles and Orifices guide goes through it.
