MTM Hydro PF22.2 Foam Cannon vs Adam's Polishes Adam's Standard Foam Cannon
Which should you buy? Our verdict on both, pulled from our full The Best Foam Cannons: 4 Compared (and One to Skip) comparison.
The MTM Hydro PF22.2 is the safe default: a brass-bodied cannon with independent foam and fan control that is built for pressure washers with a quick-connect. Adam's Standard gets you most of the way there for less, while the Sun Joe suits budget buyers with the right washer and the Foam Blaster 6 is a hose gun to skip if you own a cannon-ready washer.

Buy itThe enthusiast default: a brass-bodied cannon with independent foam and fan control that just works across almost any washer.
- Brass body and stainless quick-connect resist cross-threading and leaks that plague all-plastic necks
- Separate dials for foam density and spray fan give real control instead of one compromise knob
- Owners report thick foam across a wide range of pressure washers
- Costs noticeably more than budget cannons
- Foam output is only as good as the soap and dwell time you pair it with
Adam's Polishes Adam's Standard Foam Cannon
Buy itA well-built brass-fitting cannon that delivers thick, even foam for less than the premium picks.
- Brass fittings and a 1/4" adapter included for pressure washers with a quick-connect attachment
- Adjustable nozzle swings from a jet to a wide fan, and the air/soap dial controls suds
- Reliable thick foam that owners find easy to dial in for a safe pre-wash rinse
- Nozzle and knobs are plastic, so hand-tighten carefully to avoid stripping
- Needs a washer with at least 1.3 GPM and about 870 PSI, per Adam's page
