Hi i am looking at buying a pressure washer to clean my deck and to clean my house i found a 2600psi for $299 and a 3000psi for $399 both have a Honda motor. I was planing on using it to clean a couple other houses and decks is it better to get the bigger one or should i stick with the 2600psi?
Answer
The cleaning power is roughly proportional to the PSI rating multiplied by the GPM. While the higher pressure might not be necessary for the tasks you are considering, the added cleaning power means you'll get the job done faster with the more expensive unit. Keep in mind that you can always add distance to reduce pressure (back away from the surface), but you can't add pressure that the unit doesn't produce.
I have tried to use an old 1500 psi unit that I already had to clean a concrete driveway, but just purchased the 3000 psi machine from a home store, and the difference is amazing. My evaluation was that the extra $100 above the 2600 psi unit was well worth the hours saved. And the Honda engine gets very good reviews from most of what I've read.
I would suggest also getting the surface cleaning attachment, particularly for your wood deck. It's not really powerful enough for a really dirty concrete drive, but would surmise that it is sufficient for the wood (you don't want that high of pressure for the wood). For cleaning concrete surfaces, I highly recommend the Turbo nozzle; it takes the 0 deg pattern and spins it in a 15-25 deg (or so) pattern so that you get the dislodging pressure of the 0 degree, but in a pattern size that allows efficient cleaning.

what is the best psi to effectively remove grime and stains from all surfaces with a pressure washer?
i need to buy a pressure washer to start a small after-school business to earn some extra cash. i will need a gas pressure washer with enough power to clean driveways, walkways, fences, stone, brick, oil stains from garages, ext. what is the minimum PSI i need to be able to do these jobs effectively?
Answer
The more pressure you can get, the better. But also watch water volume too. The cleaning power of a pressure washer can be found by multiply pressure (psi) by water volume (GPM). Some manufacturers offer a lot of pressure with very little volume.
That said, 3000 psi is a good all around pressure. You can always lower the pressure by the type of nozzle that you use.
Hope this helps.
