Pressure Washing: Dissecting the Essential Acronyms
We all know that water is the universal solvent – one of the reasons why cleaning cannot be done without water. But when cleaning gets tough, extra “push” is needed. Pressure washer upgrades the cleaning power of water by pushing the water to make its burst and flow stronger. Pressure washers invaded the market not just because of its function, but also because its efficiency: it can save you water up to 80%!
However, to fully enjoy the conveniece brought by pressure washers, you must be familiarized with looking at its specs – promise this is a no brainer, not too technical.
PSI is Pressure per Square Inch. This gauges the pressure washer whether it is light to heavy duty. Below 2000 psi means a light duty pressure washer that is ideally for home use such as cleaning a car, backyard and patio furnitures.
A medium duty has a psi ranging from 2000 to 2600. This is intended for outdoor use but not for construction areas. This type of pressure washer usually found in parking spaces, driveways, decks and side walks.
For construction sites, ofcourse, needs heavy duty pressure washers with more than 2600 psi. For intense cleaning in an industrial setting, super duper heavy duty pressure washer called water blaster is needed, which has 7000 – 50000 psi.
Another acronym is GPM or Gallons Per Minute. This measures the water flow. So, less gpm consumes less water. But to fully judge a pressure washer’s cleaning performance, CU (Cleaning Units) must be obtained by multiplying GPM by PSI.
In choosing your pressure washer, PSI, GPM and CU are the acronyms to look twice.
