I know this was covered a while back but I can't locate the thread.

Which is more important when buying a power washer? PSI or GPM? I am looking for something to clean the house and drive.

One at CostCo is 3100psi and 2.4gpm with a EA190V Subaru commercial duty engine for $299. Good or no?

Good enough. Even better a month ago when it was $220 @ Sams

If you are using it for residential use it should be fine and remember use pump flush and run the fuel out when you are done using it. The reason typically you will not use it much and fuel sitting in a carb for a few months can damage the internal parts. Pump flush keeps the pump lubricated and helps reduce calcium build up in the pump. They sell that at home centers.

TTI which owns roybi has reconditioned units at their store called direct tools at the tanger outlet mall.
Sometimes you can find a reconditioned unit at Lowes or Home Depot for a good price.

Here is alittle info
Pressure Washer Specs- PSI and GPM
The PSI of your pressure washer matters more than you think. On the low end are pressure washers with a 1,000-2,000 PSI. These washers are good for most typical residential jobs. The next level up are power washers with a PSI of 2100-2900. These can be used for heavier residential purposes, or lighter commercial uses. For professional grade models, power washers with 3000 – 3900 PSI will get most professional jobs done. For tougher jobs, a pressure washer with 4000 PSI may be needed. For industrial purposes, pressure washers with a PSI of 5000 or above are typically used.
PSI isn’t the only rating to look for when deciding on a pressure washer. The Gallons Per Minute rating, or GPM, is also important. The higher the GPM, the faster the pressure washer will work. Two pressure washers may have the same PSI, but the one with a higher GPM will get the job done faster. This can save you time, as well as gas or electricity.
The relationship between PSI and GPM is demonstrated through a measurement called Cleaning Units, or CU. This number is found by multiplying the PSI and GPM. A washer with 3000 PSI and a 3 GPM will have a CU of 9,000. A washer with 3,500 PSI and a 2 GPM will only have a CU of 7,000. So the pressure washer with the lower PSI will actually get the job done faster than the pressure washer with a higher PSI.
This is not to say that PSI isn’t an important factor to look at when deciding on the right pressure washer for your needs. It is important, however, to look at all the specs before making your final decision.

Any pressure washer that costs less than $500 is not even suitable for light duty home use.

Damn. That's a hard and fast rule or are you just a pressure washer snob?

DV all you want, it is a true and accurate statement.

The pump or the cam will fail before 100 hours of use.

Then it will be thrown away.

I bought two in the price range you are looking at.

Even had a Honda engine on one-junk.


Maybe if you maintain it like an F1 car and follow all specs religiously, you'll get 200 hours out of it.

Let find a link to the one I have now...

2.4gpm
It's all about the pump, 4gpm is the
optimum goal.

100 hours of use will probably outlast me

I do get a lot of them in my repair centers that come from Lowes and Regional home centers.
99.9% the pump gets a build up of calcium from sitting and when the person cranks it they force it instead of using a pump flush and damage the pump. They also run the engine without the water hooked to the pump.
Is it the best pressure washer? No, it is a residential unit.
For the guy using it here to clean a house, sit it up a few months use it to clean a boat, and then maybe even wash a car once in a blue moon they are ok.
Again use pump flush when you store it and drain the fuel tank if you sit it up.

If I put 200 hours on a pressure washer I only paid $250 for then that's a good deal to me.

This is what you need to focus on. If it doesn't put out any pressure, it's not gonna clean. If it doesn't put out any water, it's not gonna clean

What are you pressure washing for that long? That's an insane amount of hours? My dad has a decent dewalt pressure washer that we both use and I bet combined we've both put 25 hours of use on it in 4 years. That's 2 houses, a boat we use it probably 4 times a year on, and other random stuff. I mean I feel like if a pressure washer lasted 10 years I'd probably have 50-75 hours on it, and I'd be happy with that life span.
