I've tried several pressure washers over the years, some were expensive models and some low-end models. The heart of an effective pressure washer is it's pump, so do your research there. If you can, try several models before choosing one to buy. I bought a GENERAC pressure washer 8 years ago and use it regularly for washing everything. Cars, tractors, houses, driveway, decks, you name it. It has a 5.5 hp Briggs Vanguard engine and a Comet 2.9 gpm 2000psi pump. Yes, be careful with the high pressure!
