Grade: A -
Water pressure/square inch: 1,800
Cleaning power: Black spots begone! Against the turbo nozzle, said to boost PSI to 2,050, those patches on the patio never stood a chance.
What's to like: Comes with the turbo nozzle plus a fan-style one good for spraying detergent and cleaning wide surfaces.
What's not to like: Unlike other models, this cleaner makes no design-conscious effort to conceal the detergent tanks.
Bottom line: This powerful fun machine leaves you feeling like the superhero of clean.
CORRECTION: This story originally ran in the April 2007 issue of Money Magazine and rated five power washers. The Karcher model is not included in this online version because the model tested is no longer being made.
