Surprisingly, more powerful than the 1500 psi models that are out there, while still using basically the same GPM. Very pleased with the transporting ability.
I bought this a month ago, and I wanted to see how it is before I leave a review. This is a great power washer. I washed off my back concrete patio. I hadn't washed it off in a few years, so it had some deep down black mildew, and green mildew stains on it. It took it up at about 2" strips at a time with the 15 degree tip. I proceeded to power wash the back of the house, and gutters as well. The pump ran all afternoon no problem. A few days later I did the driveway, and sidewalk with 15" surface cleaner. That went a lot faster. I still had to go back over with a tip to get some of the deep down stains again. I think if I do this every year or two, I should be able to get away with the surface cleaner scrubber alone. We'll see. I proceeded to wash the front of the house also. The pump ran like a champ all afternoon again. It's great when you release the handle it take a few seconds to top off the pressure, and then the motor shuts off. A few days after this I did the underside of both of our cars with the 16" undercarriage, and water broom. I was really excited to see this attachment was invented. After all winter of grim, and salt, etc getting on there. This attachment worked great. Another great addition that came with the undercarriage attachment was 2 1 foot extensions which came in handy doing the driveway, and sidewalk because I didn't have to bend over as much. I know that seems trival, but trust me when you are out there for a while it really saves your back. I was originally looking at a slightly cheaper power washer, but I'm really glad I got this bigger one instead.
