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.
