1. Power Washing vs Pressure Washing: What’s The Difference?

Pressure washers are machine’s that uses high-pressure water to disperse water to remove organic growth such as grime, dust, mold, and other debris loose. A power washer does the same thing, but it also uses heat to help it obtain more effective results in some cases.

2. When to Pressure Wash vs. Power Washing

A pressure washer is often recommended for large surfaces that require heavy-duty cleaning power. Pressure washers are generally not used indoors, but they work great for cleaning driveways, walkways, patios and pavers in Vancouver Washington . Operators of pressure washers and power washers should be very careful when using power washers because the added heat can damage some surfaces. It is not often that the use of a heated power washing unit is necessary on residential jobs. Grease stains in driveways for example can be removed with industrial strength degreasers.

3. Different Pressure Washer Sizes

Pressure washers can be purchased in many different levels of efficiency ranging from light duty to industrial or commercial grade. These are the important things to remember when looking at the different levels of pressure washers:

  • Light duty: These washers generally produce water pressure that is below 2,000 PSI. These units could possibly be electric as well as gas powered. They are a great choice for small needs, such as cleaning off a patio or deck.
  • Medium duty: You may want to select this type of washer if you need to wash something that’s more difficult to clean. Such as your home’s siding, fencing, or driveway. A medium-duty washer usually has a water pressure at a general range between 2,000 and 2,800 PSI.
  • Heavy duty: This might be the right choice if you’re cleaning heavily soiled concrete. Heavy-duty washers can reach pressure levels up to 3,300 PSI.
  • Professional Duty: Unless you are starting a pressure washing business than it is likely that this type of power will not be necessary. Maintenance on these types of pressure washers will be higher. Also, the general knowledge required to operate this type of unit is significantly higher. The gallons per minute and pressure put out by these types of pressure washers is usually above 3,300 psi and 8 gpm.

However, if you have to tackle particularly grimy projects, you may want to invest in professional-grade cleaning solutions.
