The two types of motors to power electric pressure washers are induction and universal motors.
The gist of the reason for this is induction motors are much larger/heavier and more expensive for the power it provides compared to universal motors. However, they are also more rugged, quieter and will have a longer lifespan.
In this guide you will learn the pros and cons of induction vs universal motors in pressure washers and we’ll show you what an induction and universal motor looks like by taking a look inside my Lavor Eagle and AR Blue Clean electric pressure cleaners.
- Low water pressure
- Water leaking issues
- Engine/motor turning off while in use
- And much more…
But first let me ask you a question:
You ever helped a neighbour fix something?
Be careful because once you do – and word gets around – you’ll be the go-to-fixit-guy-or-gal for everyone and everything.
Trust me, I know. All my neighbours now know me as the power equipment and pressure washer troubleshooting and tune-up guy.
Here’s what happens when you’re the neighbourhood fixer:
4 pm last Saturday I’m in the shed changing pressure washer water pump oil, and over the fence my neighbour says:
“Hey, James, come fix my pressure washer and I’ll give you a beer.”
5 minutes later (beer in hand) he tells me he bought a used pressure washer with water pressure problems…
…It was an electric and started-up fine but when in-use pulsed out water to start, then after 10 seconds fell to low pressure.
My pressure washer troubleshooting experience told me it was air in the pump causing the problem. We switched off the electric motor but kept the water running through the pump. After holding the trigger to keep the water running through the machine we managed to clear the air from the pump and lines. My neighbour turned the machine on again and it worked. Full pressure, no pulsing.
Why you’ll love this beginner’s guide:
Nothing is worse than a pressure washer that starts up but won’t pressure wash properly. You get excited hearing it roar to speed but then it doesn’t properly clean your surface.
That’s why we put together this in-depth power washer troubleshooting guide for you… So you can fix the problem from your garage – even with zero experience and minimal tools.
A nice-to-have to prevent squeaking and rust.
This couldn’t be further from the truth.
Lubrication is as important to mechanical engineering design as screws, welding, bearings, gears, clutches, brakes, couplings, flywheels, shafts and axles.
In my university Mechanical Engineering Design textbook, lubrication has its own chapter – taking up 6% of the 958-page Seventh Edition. It comes after rolling-contact bearings and before gears.
How big do you think the lubrication industry is?
It’s huge. The global market for lubricants was more than $55 billion USD in 2015. And it’s growing…
…With this amount of consumer spending, massive lubricant and grease company marketing spending follows. The marketing competition is fierce and gives you mixed messages, is confusing and creates too many choices of lubricating grease.
Let’s dive right in to find out.
We have already released the best pressure washer services in the 5 most populated areas of the 35 highest population states.
And we have heard from many people (from Florida to Texas to Oregon) that those recommendations have helped get quality pressure washing jobs completed without fuss or hassle.
So after many many MANY hours of research we are ready to give you a bunch more recommendations for pressure washing companies.
You know: time is money.
- If you plan on pressure cleaning an entire truck fleet…
- Or an entire parking lot…
- Or an entire commercial shopping mall building…
- Or 8 residential driveways…
In. A. Single. Day.
Then you need to invest in a big rig that can quickly clean large surface areas. You need a powerful pump capable of up to 8 GPM. You need hot water, longer hoses, water tank, spare fuel… And you need it all to go from one job to the next day-in-day-out (without fuss).
You need mobile pressure washing equipment. You need the best pressure washer trailer setup to do more power washing in less time – earning you more money per day.
Sound about right?
- The wrong way involves a powerful gas pressure washer, 0-degree blast nozzle tip attached and a 3,000 PSI water jet stream wrecking havoc on your engine components.
- The right way involves any gas or electric pressure washer, a 40-degree spraying nozzle tip attached, lance held 3 feet from the engine, and a safe water spray 2x garden hose pressure efficiently cleaning the engine.
Pressure washing your car engine can be safe, for sure, but should you even bother?
The pressure the pump can deliver is important only to knocking dirt and grime loose from the surface. PSI doesn’t tell us anything about its ability to carry the debris away from surface before it sticks again. For that, we need to look at the flow rate in gallons per minute (GPM).
More experienced power washer users will know about cleaning units (CUs), which is GPM x PSI. A 2,000 PSI machine with 2 GPM has 4,000 CUs. Combining PSI and GPM into one number gives a better idea of total cleaning power/ability.
