I was using a 1500 psi pressure washer and thought this would be a big improvement, but I was pretty disappointed in the pressure. It is definitely more than the 1500psi, maybe 2000psi or something like that, but for sure not 2x's+ the pressure of the 1500psi. I borrowed a gas pressure washer that was 3000 psi and it would be able to take the paint off of your house, this one barely cleans my sidewalk, have to go super slow and hold very close for it to clean the concrete. The different tips are a nice feature, but there is no description or instructions for them, just trial and error, plus there is no place to store them on the machine either. OK for the price. The instructions are a description of the parts, no help at all for anything. No instructions on how to use the soap dispenser either. Easy enough to use, but pretty heavy. There are wheels, but is heavy if you have to lift it up.
