3. Only run engine when water is connected to pump
4. Don't let engine idle too long while system is pressurized
5. Allow water to drain out of unit when done using, maybe put some pump treatment fluid in there when in storage.
I also like to hang up my PW hose to drain it of water after each use. You can hang it from the garage door track mounts and it'll drain quickly.
Oh and change that oil after the first 5 hours of use!
I don't see any reason why a PW can't last as long as a lawn mower, but it does require more diligence and an understanding of what you shouldn't do to the pump.

I also squirt Briggs and Stratton "pump saver" into the pump after each use. Make sure the pressure washer is stored inside during winter if you live in an area that gets down to freezing temps. Also, change the oil in the pump. They usually take 30 weight oil or 75w90 gear oil depending on the pump.
My parents bought an Excell pressure washer in 1998 with a Briggs Quantum 6hp engine and cheap pump. It got used every year to wash the siding on the house and for the cars. My dad did the maintenance outlined above on it, and I just replaced the original pump last year. The engine ran great so I just put a new pump on for 90 bucks off Amazon.
