[This review was collected as part of a promotion.] I bought the GWP3001 when I discovered that the choices for renting were either a 125lb gasoline powered one that I couldn't get into my car or a wimpy 1800psi one that would have taken days to clean the concrete. Renting the gas-powered one for 3 days would have cost more than buying this tool. Besides, I love tools. I'm very happy with the performance of this one. It took only a little over an hour to do the first job. The photo is from when I had to move the machine because I was making a mess. That's my hint: don't aim the sprayer towards the washer machine, no matter how far away you parked it. That muck splashes a long distance. Anyway, as you can see, it works very well. I'm very happy with it. I've only had it 4 days, so I can't speak to durability over time, but for now, it's great. The only (extremely minor) annoyance is that the wand holder doesn't hold the wand very securely, so I added a Velcro strap to keep it in place while I'm moving the machine. This is NOT a reason to avoid this tool.

[This review was collected as part of a promotion.] Just bought the GPW2100-it is not listed for a review. Must be a new model. Used it to power wash eaves and garage doors. Must not have had correct soap because it didn't remove the black spots from eaves. It did seem to be easy to use.
