Best Budget Foam Cannons Under $50
Foam cannons don’t have to break the bank. While premium models can cost $80–$100+, there are several budget-friendly foam cannons under $50 that still deliver thick foam and safer washes. In this guide, we’ll review the best affordable foam cannons, what to look for, and how to get pro-level results on a budget.
Quick Takeaways
- Yes, budget foam cannons work: Many sub-$50 models produce plenty of foam.

- Match PSI/GPM: Ensure your pressure washer delivers 1,200+ PSI and 1.2+ GPM.
- Foam density matters: The right soap makes more difference than the cannon itself.
- Pro tip: Upgrade later if you wash often—budget cannons are great starters.

- Brass fittings: Last longer and resist leaks compared to plastic.
- Adjustable spray: Ability to control foam width and thickness.
- Wide-mouth bottle: Easier to fill and less likely to tip over.
