For my needs, this handy little power washer performed very well. The battery life is good, considering how much water it had to pump, and once dead, the second 'included' battery was more than enough for me to power wash my entire house and fencing. The pressure is adequate for these tasks, but if you're looking to really dig deep and stripe the surface of a deck for example, this probably won't suit your needs. But for house siding, fencing, and drive way cleaning, this not only works well, but I love the fact that I can reach places in my backyard that my garden hose can't. I used a cooler with wheels filled with water to tote around my yard, and voila! Job nicely done!
