Using one with lower power will require much more work to clean the concrete surface. In addition, it's important to use the correct spray tip. I suspect that the ratings of pressure washers are often as optimistic and misleading as those used for vacuum cleaners, but the price is quite typical of an electric pressure washer for homeowners. You may be able to clean concrete to a certain extent, but at such a low PSI you won't get the full power of a commercial pressure washer system.
So which PSI pressure washer do I need? As mentioned before, we recommend using a pressure washer that has a capacity of at least 3,000 to 4,000 PSI. Whether you're cleaning the sidewalk on your property or a garage floor, you can quickly solve the toughest problems with the right pressure washing system. Damage caused by a pressure washer to concrete surfaces is usually due to excessive water pressure or the use of an incorrect nozzle. There's no denying that pressure washing concrete is the fastest and most effective method for keeping surfaces clean. With more than four decades of experience in this industry, we have earned a reputation for consistently producing durable, reliable, effective and efficient pressure washers that will help you boost your cleaning process.
There's no question that electric pressure washers between 1300 and 2300 psi can wash a concrete inlet, but they will take longer. Pressure washers are highly technical tools, and while they're easy to set up, each pressure washer is different and has its own specifications. A pressure washer with a high GPM level and a high PSI pressure will provide the best cleaning power, providing a large volume of water at a strong pressure to quickly and effectively clean large surfaces and difficult stains. Once you've connected the garden hose from the faucet to the pressure washer, don't rush too fast to turn on the pressure washer.
