PSI is good but GPM is what does the work. I also wash my cars.Ĭouple notes: If you dont want extra accessories, then a gas will be the best way to get it done because the GPM is usually higher as well as the PSI. I use mine to do all the stuff you mentioned. A lot of folks calling for gas in here they aren't wrong, but you can make a modest electric unit work. I should have skipped the hose reel model and gotten the 4000 instead, but otherwise a big fan. It's done most everything I can need it for. I have a 2030psi SunJoe SPX40001 I've been using for a few years now. Better yet, if you have easy access to non-ethanol gas, always use that in small engines. That will use up the gas in the carburetor so if it sits for a while, you don't have to worry about things getting clogged up with ethanol gasoline. As you are getting ready to finish up, turn off the fuel and let the engine die out. The nice thing though about most modern small engines is you have a fuel shutoff. Of course they are louder and you have a small engine to worry with. The higher flow rate along with higher pressures from gas powered pressure washers will do a significantly better job. Electric tends to be well below 2gpm while gas usually starts right around 2.3.

The important number though isn't PSI but gallons per minute. I've only used it so far to wash my vehicles and see what it could do to clean my deck, and it worked great.Įlectric is great if you want to wash your car or clean off some patio furniture, but if you need something to clean concrete, you want something that has more power. I just got a Ryobi gas powered pressure washer that does 2.5 gpm at 2900 psi. If you want something that is powerful enough to clean concrete and decks, then gas powered is the way to go.
