They sometimes sell power washers at Costco. I have seen both the electric and the gas types available there. Gas ones can dial up more PSI than the electric models and don't require a power outlet. They also cost more. Though the electric models are probably strong enough to cut into your siding. Sometimes less is more. You can probably rent a power washer at HD. In my experience the high pressure hoses on these things don't last very long, if you don't need one for future use you might pay less in rental than what you would pay on a hose replacement on a unit that you own.
