The most critical piece of equipment for any pressure washing business is the pressure washer. You'll want to choose a model that is at least 4 gallons per minute or more, as this will allow you to handle various cleaning tasks quickly and efficiently.
Most commercial hot water pressure washers can be used for any cleaning situation with the application determining the nozzles and chemicals used. 90% of the successful commercial operators use a flow volume of 4 gpm or more. Below 4 gpm there is not enough water volume to clean efficiently.
You'll need a power washer that provides a force of 3,000 PSI or more. The higher the pressure, the better and faster is the cleaning. If you want to use a lower pressure on certain surfaces, you can always attach a larger spray tip to it.
Commercial-grade pressure washers start at 3100 PSI and can have GPM ratings as high as 4. These durable machines make light work of many large-scale cleaning jobs, including cleaning decks and driveways, washing two-story homes, removing graffiti, and stripping paint.
A commercial medium-duty pressure washer will have between 2,600 and 3,100 PSI and will use 2.5 gallons of water per minute. If you're using this machine for 30 minutes, you'll need to ensure you have around 75 gallons of water in the tank.
Medium Duty 2000-2800 PSI
This classification ranges from as low as 2,000 PSI to as high as 2,800 PSI. You can use a medium-duty pressure washer for almost any surface. They're great for cleaning concrete, brick, and wood.
Concrete and asphalt require more cleaning power. You'll want to use the turbo nozzle on the 1600 PSI for hard-to-clean driveways, sidewalks, and patios as well as brick paving. For wood decks and painted surfaces, switch to the gentler 40-degree nozzle.
Concrete cleaning calls for powerful pressure washers featuring high pressure levels of 3000 PSI. However, if you will be using the power cleaner to maintain a range of surfaces in addition to concrete, choose one with adjustable pressure levels and set it to about 3000 PSI when you need to clean concrete.
Generally, contractors or professional cleaners will find that they prefer a higher GPM machine over PSI since they use cleaning solutions to loosen grime instead of relying fully on PSI, their job primarily becomes one of rinsing the dirt away. The higher the GPM the faster it will be to clean large surfaces.
Yes, you can increase the GPM on a pressure washer safely by following these steps: Choose the correct nozzle for the job. Adjust the pressure regulator to the correct setting. Do not exceed the machine's maximum PSI rating.
The main difference is that power washing uses highly pressurized steam to do the cleaning while pressure washing just uses unheated tap water, without the help of a heating element.
For most cars, a psi between 1200 and 2200 is recommended. This range provides enough cleaning power to remove dirt and grime without damaging the car's paint or delicate surfaces. Yes, you can use soap with a pressure washer.
The 3000 psi machine can put out 5 gpm while the 4000 psi machine has to be cut back to 3.5 to 4gpm in flow. The 3000 psi machine has 14.4 (lb) of impact force which relates to 10 to 20% faster cleaning than the 4000 psi while using a similar amount of horsepower and fuel.
The RYOBI 1800 PSI 1.2 GPM Electric Pressure Washer is the perfect powerful yet portable option to get the job done. This pressure washer is ideal for light duty applications like cleaning small driveways, sidewalks, decks, windows, patio furniture, campers, bikes, boats, and many other recreational applications.
Normal psi for a home pipe system is between 30 and 80 psi. While you don't want the psi to be too low, it violates code to be above 80. Instead, you should aim for a psi that's between 60 and 70.
Whether you're shopping for a gas or electric pressure washer, pay attention to the nozzle (or nozzles), hose, and (in the case of an electric model) power cord. We discuss nozzles below. As for hoses and power cords, the longer they are, the more mobility you have. Ideally, each should measure at least 30 feet.
A medium-duty pressure washer is strong enough to blast greasy, grimy stains from residential areas. Homeowners can safely clean sidewalks, concrete driveways, decking, and siding with a 2,000 to 3,000 PSI washer.
There's no doubt that electric pressure washers from 1,300 to 2,300 psi can wash a concrete driveway, but it'll take longer. If you have a large driveway with lots of stains, you'll want more power to do the job faster.
Our recommendation ranges from as low as 3,000 PSI to as high as 4,000 PSI.
Yes, if it's concrete. Concrete driveways (and walkways) can readily withstand a powerful cleaning without etching. Generally, a finer nozzle will be more effective at spot-cleaning grease stains. For mold or mildew, use lower pressure and coat the surface in suds first.
Often more affordable than higher strength concrete, 2,500 PSI can be useful for driveways and walkways. However, some may choose a stronger concrete, like 3,000 PSI, to avoid excessive cracking. A good use for this concrete is a walkway on the side of a home that doesn't receive excessive traffic.
The higher the PSI the more durable your concrete will be and will thus be resilient to cracking. The average residential project uses a minimum of 2,500 to 3,000 PSI; however if you're concerned about cracking then we recommend talking to your concrete contractor about stronger products on the market.
