Best Pressure Washer for Foam Cannon Detailing – Buyer’s Guide
Looking for the best pressure washer to use with your foam cannon? Not all machines will give you that thick, clinging foam you see in pro detail videos. Let’s break down the numbers and the top picks.
In this guide, we cover the ideal PSI and GPM ratings, electric vs gas options, and the exact models that deliver rich foam and safe cleaning power for car detailing.
What PSI and GPM Are Best for Foam Cannons?
The sweet spot for car detailing foam cannons:
- PSI: 1,300–2,000 is ideal (don’t go over 2,500 PSI for car paint)
- GPM: At least 1.4 GPM is recommended for thick foam
- Electric: Quieter, more convenient for home use
- Gas: More power, but often overkill for car detailing
Pairing your machine with a true high-foaming soap like The Super Soaper will dramatically improve your results regardless of machine.
