The short version: three of the most-recommended foam cannons in detailing, and the argument between them comes down to how much you'll pay for the last 10% of foam. MTM Hydro PF22.2 is the foam champion — the thickest blanket and the best build, at the highest price. MJJC Foam Cannon S is the value sweet spot the reviews point most buyers toward — nearly MTM foam for meaningfully less. Chemical Guys TORQ Foam Blaster 6 is the familiar big-brand name, easy to buy but out-foamed by the MJJC for similar money. Same quick-connect fitment, three different value propositions.
This is the head-to-head. For the wider field including budget champions, see our best foam cannon ranking, and the foam cannon hub covers how to dial any of them in.
MTM vs MJJC vs TORQ at a Glance
MJJC Foam Cannon S
Best for most enthusiasts — premium foam without the top price
How We Compare Them
We rank on the crowd, not a stopwatch. For each cannon we weigh the aggregated Amazon rating, how many owners stand behind it, and the recurring themes in their reviews — foam thickness and cling, build quality and longevity, adjustability, and fitment. When thousands of owners converge on the same verdict ("this one foams thickest," "this one's the best value"), that consensus is what drives the ranking. Prices shift over time; the standings reflect what owners consistently report.
Foam Thickness: MTM Leads, MJJC Shadows It
This is the headline criterion, and the review consensus is clear: MTM Hydro PF22.2 makes the thickest, most consistent foam of the three. Detailers describe the closest thing to a shaving-cream blanket that clings to vertical panels long enough to dwell properly — it's the cannon people upgrade to. But here's the twist the reviews keep surfacing: the MJJC Foam Cannon S is right on its bumper. Owners who've run both report the MJJC produces foam that's genuinely close — thick, clinging, satisfying — for around $30 less. The Chemical Guys TORQ Foam Blaster 6 makes good foam too, but it's the one owners most often describe as "fine" rather than "wow," landing it third on pure foam quality.
Build and Longevity: Two Tanks and a Trooper
Build quality tracks price here, mostly. The MTM Hydro PF22.2 is the premium object of the group — metal-quality fittings, a solid feel, and the fine adjustment that reviewers single out as the best of the three. The MJJC punches above its price on durability; owners consistently note it's built to last and doesn't feel like a corner-cut version of the MTM. The TORQ is well-made and backed by the biggest brand-service network of the three, which some buyers value — but on raw materials and adjustment feel, the reviews place it a step behind the other two.
Value: The MJJC's Home Turf
Foam-per-dollar is where the ranking flips. The MJJC Foam Cannon S is the cannon the reviews reward hardest, because it delivers roughly 90% of the MTM's foam and build for meaningfully less money — the classic enthusiast value play. The MTM only makes financial sense if that last slice of foam quality genuinely matters to you; it's a premium you pay for a marginal gain most owners can't see. The TORQ sits in an awkward spot: priced close to the MJJC but out-foamed by it, so its case rests on brand familiarity and availability rather than value. If you're optimising cost-to-foam, the MJJC is the apex of this particular run.
The Verdict: Which Cannon for You
All three will blanket your car — the choice is about where you want to spend.
- Pick the MJJC Foam Cannon S if you want the smart-money buy: near-premium foam, durable build, standard fitment, and a mid-tier price the reviews back over both rivals. It's our overall pick of the three for most enthusiasts.
- Pick the MTM Hydro PF22.2 if foam thickness is the whole point and you want the best of the field, price aside. It's the durability-and-foam champion for serious detailers — the cannon you buy once and keep.
- Pick the Chemical Guys TORQ Foam Blaster 6 if you'd rather buy a familiar, widely-stocked brand and value easy availability and support over squeezing out maximum foam-per-dollar.
Whichever you choose, the cannon is only one leg of the tripod — pair it with a proper high-foam soap and enough pressure washer flow, or none of them will foam to their potential.
