Make your patio, siding, car, boat, or RV squeaky clean — without the expense of a pressure washer. Mpact patented technology pulsates water 40 times per second, without any moving parts. Even better, it uses up to 40% less water than a traditional wand! The wand makes it easier to access hard-to-reach spots, while the head pivots to direct water at the perfect angle. Great for gutters too!
