Taking note of the power source was easy, as they're either 120 volts, a 20-volt battery, or gas-powered. We weighed each pressure washer on one of our scales, with hoses and attachments included. We then subtracted this static water flow rate reading from the 'powered on' reading.
For our water flow rate reading, we took note of the rate prior to using the pressure washer itself-to account for leaks. Because of this, our testing parameters included data points that are useful for a wide range of power-washing jobs.įor our objective numbers-driven parameters (who doesn't love those?), we tested maximum water pressure with a psi gauge, water flow rate with a water flow meter, and noise level with a decibel meter. While the vast majority of our testing consists of strictly automotive products, we know that pressure washers can do far more. To help you choose which pressure washer is right for washing your car, we put nine of them through some serious Gear Team testing. For car, boat, and RV cleaning, a smaller, less powerful-and less expensive-pressure washer is plenty of tool for the job. Tough household tasks, like stripping the varnish off a deck, will require a more powerful pressure washer than those listed here, and you wouldn't want to use one of those on your vehicle, anyway. A good rule of thumb is to decide which jobs you want your pressure washer to accomplish before buying one. However, there are a few things to keep in mind before you go power-washing your ride. It's a nice tool to have anyway, with plenty of satisfying cleaning options around the house. There are multiple ways to clean your car, but one of the fastest and most efficient options is bringing out the old pressure washer. With apologies to the Masters, washing your own vehicle is also a tradition unlike any other.
