120v ones suck.
That's why I went to a 240v 56c frame Baldor motor on a general pump.
Even my 240v electric pressure washer is no match for the gas powered one.
My gasoline one does about 2.3gpm at 2,200psi. That's actual measured, yes I aquired a gauge that can measure that pressure. Measuring volume is easy.
When the manufacturer of the cheap ones says "1.5 gpm" and "2,000psi" you do get both. Just not at the same time.
You get what you pay for.
Doing a driveway and wooden deck you absolutely want the raw power of the biggest gasoline powered one in your budget.
Trying to wash a driveway or deck with an anemic underpowered 120v unit would be madening.
If I was going to wash a drive way I would fire up both my gas and electric and use both spray guns at the same time.
