Power Washing concrete driveway, sidewalk, patio and porch

The larger end of the spectrum, for homeowners in my humble opinion anyway, we find the butt kicking entry-level professional sized pressure washers. Professionals need machines that are extremely easy to set up, take a no nonsense approach to power washing, that get the job done quick, fast, and in a hurry.The most important thing to remember, when comparing lesser-powered pressure washers to more powerful machines, we need to understand what and how GPM effects the way a pressure washer works. GPM is simply the measure of how many Gallons of water per minute a pressure washer pumps through the high-pressure nozzle on the end of the cleaning wand. The more water pumped through the nozzle at a given pressure, the more cleaning power, or cleaning units a power washer will have, and the harder it will be to control.Imagine for a moment, getting behind the wheel of a small gas sipping compact car. Start the engine, put the car in gear and put the gas pedal to the floor. What happens, it takes off no excitement, no smoking the tires or any white-knuckle experience. Conversely, jump behind the wheel of a 600hp Viper, fire that puppy up, put her into gear foot on the floor and enjoy the drive, if you dare. Now I know there are some of us that will enjoy the experience, still others of us might just soil their under pants.
