Completely ignoring the advice here to go bigger, I went out and got the smallest electric pressure washer I could find--just didn't want to invest over $100 in it. And I'm still thrilled. Used carefully, the washer gets grime out of the non-skid that even a brush doesn't get, and I'm not washing soap or detergent into the bay. And even the small one saves time and effort. Lazy? Absolutely. But I think, good lazy.
