Pressure Washer PSI Question
Posted on 9/5/24 at 1:17 pm
Posted on 9/5/24 at 1:17 pm
Been a long time since I posted but this place has never let me down. Apologies if something similar has been posted recently.
In the market for a pressure washer for residential - mostly just brick, concrete (sidewalks and driveway).
I have a 1700 PSI GreenWorks one that does the trick but takes a while.
Looking to get a larger machine and just curious if ~3100 PSI is too much for what I'm doing? Only concern is that it'll damage the concrete or something
Been looking at the SIMPSON 3,100 PSI 2.3 GPM Gas Megashot MS61217 Residential Pressure Washer
Recommendations for others around ~2700-3100 PSI that won't break the bank are welcome.
TIA

I have a Ryobi 3100 PSI/2.3 GPM that does fine for the driveway and such.
It has a Honda engine on it, scored it from the curb last year. They're around $399 new.

Engine is more important than the shell imo. Can't go wrong with Briggs & Stratton or Honda.

PSI is only one factor in the pressure washer equation. PW efficiency is measured by "cleaning units" (CU, which is PSI x GPM.
In general, for washing purposes (especially concrete/bricks) you want the highest GPM you're willing to pay for. Thats whats going to wash away the grime. Pressure is for blasting away things (similar to sandblasting). I wouldnt want to go above 3000psi for concrete/bricks or you'll be blasting away the aggregate.

Appreciate it! Hadn't considered GPM in the equation. Knew it was a good idea to ask folks who know what they're doing before I just started blasting away.

Yup, when I saw mine on the curb I thought "damn it's a Ryobi". When I saw it was a Honda engine I pulled over and grabbed it. $20 carb and it runs like new.

I'll probably end up going with that one as well. Only $70 more than the Simpson one and has a Honda engine.
Read some reviews and it looks like at least at one point Simpsons used Honda engines as well but may have switched to CRX.
Now if only I could get lucky enough to find one on the curb as well
Appreciate the help!
ETA: Actually looks like you CAN get a Honda engine on Simpson, just gotta pay more. Ryobi looks like the move.

Looking at one as well. Mainly for hardie board and driveway. Like the idea of an electric but curious if gas would work better. I know Honda motors are the best but which brand is better?

Facebook marketplace, you may find a commercial one for the price of a new Home Depot residential washer.

I bought an electric but returned it right away.Just wasn't powerful enough for what I wanted. Have a Simpson 3100psi with Honda engine. Night and day difference.

Soft wash first with 30 second cleaner or Mold Armor. Gas pressure washers are usually best for concrete and removing paint.

I would focus more on the GPM than the PSI. The PSI is above 3,000 which is plenty. But you want to move as much water as you can allow. Test your water pressure at the house and calculate your GPM at the source. Then you’ll know what will work best for you. I have a STIHL commercial pressure washer but I have to be careful because it pushes out water faster than my house can send it any time we are using too many appliances on the inside, and it will actually cause the engine to enter safe mode and flood
Point being the more water you can move the better, PSI isn’t as important as most think. But be careful your unit doesn’t move more water than you can supply. Because you’ll have wasted money and may not ever get the full use from the machine
Oh and my opinion is the Simpson model you’re looking at is a quality machine. Not the best GPM but still good enough for DIY. Honda engines are the best, but Kohler engines are very good too.

This 100%
I have learned that I have been doing it wrong for years trying to pressure wash siding, wood fence, etc. It actually does more harm than good becaus it will open up the seal on the material and lead to rapid deterioration from water exposure

Pump is more important than the engine. Maintenance and proper storage is more important than both. I've got an old 2500 psi Karcher with a little AR pump and a 3hp Tecumseh engine, still runs great and got to be close to 30 years old.
