Pressure Washers

When choosing a new pressure washer you will be faced with many decisions. It's easy to become intimidated by all the different terms and specifications, however this article will help you understand the basic facts needed in order to make a wise business decision.

You will need to purchase a pressure washer that will have the right capabilities for the type of work you plan on doing. If your equipment is too powerful you can damage what you are cleaning which may result in costly repairs or litigation. If your equipment is too small, it will take you longer to do certain jobs and you will lose money.

Types of Pressure Washers

Gasoline Powered

Common Terms You Should Know

PSI - Stands for Pounds per Square Inch. This is the pressure rating of the machine.  

GPM - Stands for Gallons per Minute, which is the flow rate of the pressure washer.

CU - Stands for Cleaning Units, which is PSI multiplied by GSM

Think of the PSI rating as the pressure washers ability to scrub dirt off a surface. The GPM is the rate at which the machine can rinse away that dirt. Contractor grade pressure washers are usually between 3000 - 5000 PSI and 3.5 - 4 GPM.

Hot and Cold Water
Most jobs can be done with a cold water portable machine with the right chemicals. If you are tackling jobs with heavy grease or need to strip surfaces then you will need a hot water machine. Hot water machines are worthwhile because they will save you time when it comes to cleaning any type of surface. Cold water machines can be upgraded to hot water by purchasing an accessory called a Hot Box.  

Electric Powered
The advantages of electric pressure washers are they don't require much maintenance, are quiet, and can be used for odd jobs indoors that you might not be able to access with a gas powered machine. They also can be used for smaller jobs such as detailing cars or deck cleaning.

Portables and Skid Units

Trailer Mounted Pressure WasherYou can operate a pressure washing business with a portable machine, however your customers might not be as impressed compared to a trailer mounted machine. Portables are helpful when trying to get wash areas that you can't reach with your trailer mounted machine or skid unit. The skid unit is a stationary machine designed to be installed on a trailer.

Trailer mounted units are beneficial because you can carry a large water tank. This will allow you to do jobs such as new construction cleanup in areas that might not have access to water. For large water tanks you may need to make sure you have brakes installed on the trailer so you don't burn up the brakes on your vehicle. Water weighs 8 pounds per gallon so a 200 gallon tank along with the weight of your equipment can be taxing on your vehicle.
