Best Pressure Washers for Foam Cannons
Want maximum foam from your cannon? Here are the best pressure washers to pair with your foam cannon setup.
The pressure washer you use with your foam cannon makes a huge difference in how much foam you get and how evenly it’s applied. Too weak, and you’ll get watery foam. Too strong, and you risk damaging your paint or blowing seals in your cannon. This guide will break down what to look for in a pressure washer and recommend some of the best options.
What Makes a Pressure Washer Good for Foam Cannons?
- ✅ PSI (Pressure): At least 1,200 PSI is recommended for good foam output.
- ✅ GPM (Flow Rate): Aim for 1.7–2.0 GPM for optimal performance.
- ✅ Electric vs Gas: Electric is quieter and easier for detailing. Gas has more power but is overkill for most.
- ✅ Quick-Connect Fittings: Makes setup and takedown fast.
