Has anyone had any experiences with the
larger electric power washers? I had a
small 3.5 HP gas unit, which was pretty
adequate for my home and deck cleaning
chores. Now that it is history, I am
toying with one of the 1800-2000 psi
electric units, but I am a little afraid
they will not perform. Any first hand
experiences would be appreciated.
I had a Systema (sp?) brand. More or less the same as the bigger
electric unit made by Karcher.
Worked ok for general cleaning, although slowly. Didn't last very
long, they are cheaply made. Now have 6hp gas unit. Much faster and
If you're going to do big jobs like decks or siding or driveways,
don't waste your time with the electrics unless you have *way* more
time than money.
The power source, gas or electric has no bearing on how well the unit
will perform. What is relevant is the power available and the quality of
the unit. A 6hp electric (real, not inflated consumer numbers) will be
just as powerful as a 6hp gas, presuming comparable pumps and quality.
As a point of reference, all the various food processing, meat packing,
etc. plants use electric powered pressure washers daily for cleaning and
sanitizing. The difference is that those are industrial grade units.
What is relevant is the power available and the quality of
6hp electric is not standard, 7.5hp would be the next standard size up. It
would require 22 amps at 230 volts per NEC. Just the motor alone would cost
about the same or more as the whole gas power washer unit.
It was an example, not an exact number. Yes, a "real" electric pressure
washer requires "real" power to operate. Yes a "real" electric pressure
washer is an industrial grade unit and not cheap. That electric motor
will of course outlast several gas engines or more.

Electric motor ratings get fudged as well. They often rate them based on running
them with the maximum voltage they are rated to withstand intermittantly. Most
"3 hp" spa pumps are really about 1.75 HP under normal operation.
No trickier than buying the right receptacle and plug. The 5HP washer
I have comes with a 35 foot cord so it is fairly portable anyway.
I installed receptacles at both ends of the garage so I can use it in
the driveway and back on the pool deck. That is pretty much the only
place I use a pressure washer anyway.
LOL! I guess, theoretically, one could make an extension cord almost any
desired length. In a previous home we had a gas dryer, but the area was
also supplied with 220 VAC for an electric dryer. I put together an
extension cord of about 25 feet to reach a commercial flash freeing unit
that sat on our enclosed utility porch. I would have had an additional
outlet installed, but we only planned to stay there a couple of years.
Worked fine for the duration. All you need is the appropriate plug,
socket, and 8 guage wire in the high voltage cable. Most of the big box
stores carry these parts. I used the twist lock connectors to prevent
I had a Karcher electric, works well but lasted about 14 months with not
much use. Wash my car about 7 times and the driveway and thats all she got
before it came apart. Its junk with too much plastic on critical components
and will leak in no time.
This was replaced with another Kracher gas with a Honda engine, more metal
parts and better components but at 2-3X the cost of the electric.
Both electric and gas did a good job with the electric being slower.
Now have 6hp gas unit. Much faster and
