What is HP, PSI or GPM?
HP stands for horsepower.
PSI for pounds per square inch.
GPM for gallons per minute

What's most important: HP, PSI or GPM?
The HP of a pressure washer is divided up to produce both the pressure at which the water is released (PSI) and the number of gallons that are released (GPM). For example, a 2 HP motor can produce 2.1 GPM at 1600 PSI or it can produce 3.0 GPM at 1100 PSI. Cleaning power is a function of both volume and pressure.

Do I want a gas or electric pressure washer?
Gasoline engines are best when you need a portable unit. Since electric motors are quiet and emit no exhaust, they are ideal for indoor use.

What's the difference between belt drive and direct drive?
Direct drive means that the pump is connected directly to that source, while a belt drive unit transfers energy from the power source to the pump along an intermediate belt.

Should I buy a hot water or cold water pressure washer?
It always depends on what you are cleaning and how fast your want to get the job done. Hot water can decrease cleaning time and help detergents and chemical cleaners work better.

What safety features should I look for?

A safety relief valve on hot water units
Automatic shut-off switch
Float tank/anti-siphon device
Trigger gun
Thermostat

Should I buy a portable or stationary unit?
A portable unit is convenient, especially if you have multiple areas to clean. If your stationary unit is permanently installed, service and repairs can be more expensive since the technician will need to travel to you location.

What other equipment will I need to make my pressure washer efficient?
Different brushes, nozzles, wands or chemicals can help meet the demands of your specific cleaning job. Hose reels can also increase safety and extend the life of the hose.

For vehicle washing, you may want to install a water softener depending on water conditions.

How will I need to maintain my pressure washer?
Your dealer can walk you through maintenance for the pressure washer you are considering. Make sure you purchase a machine for which parts are readily available.

Is there a difference in pressure washer brands?
You should always make sure to select a brand that is easily serviced. U.S. manufacturers make for more accessible parts delivery and better maintenance. The manufacturer and dealer's experience may also reflect what kind of service you can expect down the road.
