Why it's worth it

Greenworks built this cannon for its own electric pressure washers, and the fit is the point. It's rated to 3,700 PSI and 3.0 GPM with a 1-liter bottle, and owners report a metal connector that holds up better than the throwaway cannons bundled with washers.

Electric pressure washers outsell gas units in driveways, and they're the reason so many people conclude foam cannons are overhyped. Most electrics deliver 1.2 to 1.6 GPM. Feed that into a cannon tuned for a gas machine and you get soapy water. This one is built around the output range of the Greenworks electric lineup, so the pairing is at least matched from the start.

The connector is the quiet upgrade here. Owners who moved from the flimsy plastic cannon included with their washer to this one describe the all-metal quick-release as the most noticeable difference — it seats fast and doesn't shear off after a few uses. That's a boring improvement that saves you buying twice.

From our review of 8 snow foam cannons, by Ben Carter, Tech Editor

What we like

  • +Electric pressure washers outsell gas units in driveways, and they're the reason so many people conclude foam cannons are…
  • +The connector is the quiet upgrade here
  • +The 1-liter bottle covers a single car without a mid-wash refill, and the wide mouth makes filling straightforward

What to know

  • –It's meant for Greenworks washers, and compatibility with other brands is inconsistent enough that we wouldn't recommend buying…
  • –The more serious complaint is the bottle-to-collar joint
