simpleflat LBlack14 It's more about gallons per minute than PSI. Consumer grade electric pressure washer GPM are about half of gas models. And about 10x less than commercial gas powered machines. They work, but it takes much longer to complete the job with moderate PSI and low flow rate. Additionally, they are often hooked up to low flow spigots with small diameter hoses. Same reason why a pancake air compressor from Harbor Fraught has no trouble running a brad nailer but won't run a paint sprayer for more than a few seconds. I guess it's not a big deal when you're retired and have unlimited time to clean the driveway or deck railings.
Typhoon simpleflat Yup…. I’d wash the house every year with my gas powered Karxher 2500 psi. Don’t know the GPM. Not going out to look either. The kid who does my outside Christmas lights also does power washing. We had him do the house…. So I know what you mean. Took him a fraction of the time.
Sneakylong I have a Greenworks 2000 psi. It's fine for what I need it for. Cleaning the mold and mildew off the pool cage, the pool deck, vinyl fences, front entrance vestibule etc.. Have had people with more powerful ones and they'd rip my pool screens.
