It was a little tricky getting it started the first time...follow the exact instructions, don't try taking any shortcuts. It does an okay job, we have a large patio and it's covered with tile and it probably took me an hour instead of 15 minutes w/my old gas one but here's the huge difference. I can start this one by myself, I don't have to go buy gas for it and it does the job....it'll just take you longer.
It does a good job for a lower price pressure washer. Used it to pressure wash before painting as well as pressure washing a blacktop driveway before seal coating it. Seems to be pretty well built but the 25ft hose is a little shorter than I would have liked. I bought a 25ft extension hose the solve that issue though. Can't say how long it will last but so far so good.
