Gas or electric makes no difference... it's the Pressure and GPM. A 2000 psi @ 1.6 gpm gas powered washer will do exactly the same work that a 2000 psi @ 1.6 gpm electric will do.
Here's a decent article https://www.goodway.com/hvac-blog/2011/03/flow-rate-is-key-when-choosing-a-pressure-washer/ |
It’s Newton’s second law. The force that dislodges the dirt from your driveway is equal to the mass (amount of water) times the change in velocity. Velocity is determined by the psi behind the water jet. So yes, more mass at the same psi = more forces against the dirt.
