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.

I'm looking for a good quality pressure washer for cleaning cars. It needs to be able to draw from a water tank without assistance, and it needs to be reliable. About $200 is my budget, but I'd like to keep it as cheap as possible while still keeping quality.


Answer
For $200 you are not going to get any kind of quality pressure washer.
You need a washer which operates at 1800 PSI or higher pressure output to perform effectively. They start at around $350 - $400 dollars. I do not know of any commercially available pressure washers which will draw from an unpressurized tank - they all are designed to operate from a pressurized hose delivering 3-5 GPM @ 20+ PSI.
