The downside to using pressure washers is that they tend to cause damage to surfaces that are too delicate. In addition, the high pressure of the water spray can cause damage to surfaces you don't intend for it to reach, such as brick or stone surfaces.
1) Pressure Washers use less Water
If anything, using a hose might only provide moisture to help mold grow along your driveway and other surfaces. In contrast, power washers get rid of mold quickly, consuming less water overall.
When selecting a pressure washer, it's important to know which nozzle is used for different tasks and surfaces. Pressure washers often come with color-coded interchangeable nozzles or an all-in-one adjustable nozzle. Both types of nozzles allow you to change the angle of the water spray depending on the task.
A standard vertical shaft power washer comes with a 100-hour life expectancy, whereas a standard horizontal shaft pressure washer comes with 400 hours of life expectancy.
It is not a good idea to let your pump run without pulling the trigger because water will stay inside the pump and cause pump cavitation. There are several options for timers. You may decide to go with an auto shutdown, complete shutdown, or smart timer.
Give Your Pressure Washer a Break
Cooling down your pressure washer properly will require a complete shut-off. Leaving them idle isn't enough because the machine will still hold water inside the pump. As this water heats up, it will melt the seals on the pump.
Heavy-duty tasks like stripping paint or removing graffiti require 2,800 psi or higher and a gpm of 3 to 4 (8,400+ ECUs). Commercial-grade pressure washers, intended for regular use and built and powered accordingly, start at 3,100 psi.
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.
The pressure used in this technique is typically much more substantial than what can be done with soft washing, making it the perfect choice for homes covered in tough stains or paint. The downside to using pressure washers is that they tend to cause damage to surfaces that are too delicate.
Axial cam pumps are direct drive, meaning they spin at the same speed as the engine. They will wear down faster than a triplex pump, but provide a great deal of pressure and performance. Triplex plunger pumps are the highest quality pressure washer pumps, offering longer life and better performance.
Using a bucket to supply water to a Pressure Washer is also simple to achieve and can be done by using a suction hose; placing one end of the hose in the bucket of water and the other end connected to your Pressure Washer. Fill up your bucket with water.
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.
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.
Electric pressure washers are lighter, more nimble, and far quieter than their gas counterparts. And like all electric and battery-operated tools, they start instantly and are significantly better for the environment because they don't produce any emissions.
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.
What brand of washing machine is most reliable? Whirlpool, LG, and Samsung are the most reliable brands of washers. Yale Appliance found that less than 7% of the sales of these units required servicing. J.D. Power also ranks Samsung and LG as the highest-ranking manufacturers in customer satisfaction.
Ease of Use
Gas pressure washers are more powerful and easier to use for heavy-duty cleaning. You won't have to worry about tripping over a power cord as you work, but gas pressure washers are loud and produce harmful emissions, so they should only be used outdoors.

So, can you power wash in the rain? In short, yes. While there are safety precautions you must take, power washing in a light to medium rain can speed up and enhance the power washing process.
When using a portable pressure washer, there is no need for any more than 100 feet of hose. With proper set up of the portable machine, you can easily get 200 feet of coverage because you are using two different hoses collectively. You could easily add an additional 50 foot spare hose for larger projects.
A typical 13 HP Honda portable power washing unit uses about a gallon an hour; your cost estimate per hour would be around $4.25 to account for inflation over time. The larger 20 HP power washers would use just slightly more fuel and your estimate should be about $5.00 per hour for that size machine.
