The first Cam wall mount electric powered pressure washer packs quite a lot of features. This professional pressure washer from Cam Spray is driven by a 20-amp motor and a water delivery system that’s able to exert a 1450 PSI at 2.0 GPM, making the total cleaning power of this unit around 2900. Even though it’s not the strongest wall mount pressure washer out there, it will tackle dirt head-on.
I admire the sealed, water-proof design of the electric motor. You can be sure there won’t be any short-circuit problem from water particles getting into the motor.
Although the name says ‘cold water pressure washer,’ this unit and its 50-foot hose can handle hot water up to 160 degrees Fahrenheit. I think the motor is noisy; not enough to wake the neighbors though, but you’ll hear it whining until you start splashing the water.
It has an industrial motor with thermal overload protection.
The pressure washer makes provision for a safe and secure place to hang the gun, hose, and wand.
Well-built with ceramic plungers and stainless steel valve.
Has a low-pressure chemical injection technology for mixing concentrated liquid detergents.
The next Cam wall mount electric powered pressure washer falls short of the first. I consider this model more of an entry-level professional pressure washer as it is driven by a 15-amp, 1.5 HP motor, and the water delivery system can generate just 1000 PSI at 2.0 GPM, which brings the total cleaning power of the unit to 2000. Not the strongest and definitely not the weakest, but it’ll handle dirt that has sat for a week or two on any surface.
Like the previous model, it comes with a sealed, water-proof electric motor. The sound of the running motor is lower than the previous one, which is to be expected from a smaller and less-powerful motor.
The electric motor in the pressure washer is completely sealed.
Good thermal dissipation keeps the product from overheating.
Similar to the previous two, this model is designed to deliver industrial-grade performances. Right off the bat, you will notice the simplistic yet modern design of the unit. It is equipped with a low-pressure chemical injection for the application of concentrated liquid detergents which is activated by using the soap tip. It comes with a 0°, 15°, 25°, and 40° Q-meg tips and trigger gun.
The power of this highest pressure electric pressure washer comes from its 2 HP, 120 Volt/20 Amps single phase motor which exerts a whopping 1450 PSI at 2 GPM bringing the cleaning power to 1900. You also get a 50-foot long steel-braided pressure hose that will help you reach every corner of the surface you want to clean.
Frame features an industrial coating and grommets to hold nozzles.
Not much to differentiate this model from the previous one other than the extra GPM. This unit has a 2 HP motor that draws a current of 20 Amps to exert a pressure of 1500 PSI at 2.2 GPM bringing the total cleaning power to 3,300.
I know you don’t expect to scrape paint with a value like that, but everything else is fair game.
This pressure washer is made to work multiple hours without breaking.
Draws 20 Amps.
Has an auto start/stop feature.
Applicable for light-duty assignment and is fairly difficult to assemble the tool. The blade has a few adjusting positions making it not work effectively.
My personal favorite. The first thing you’ll notice about this model is the robust yet modern design. The unit is enclosed inside a stainless-steel frame that offers protects from moisture. The frame also doubles as a storage for the 50-foot hose. It offers two hooks to hand the hose and trigger gun on. Then there are grommets for storage of your Q-Meg nozzles and dual chemical valve which gives the freedom of choosing between two different chemical concentrations at the turn of a knob.
It’s powered by a 5 HP, triple-phase motor that draws a current of 15 Amps. What you get is 2000 PSI at 4 GPM which brings the total cleaning power to 8,000.
Powered by a 5 HP motor.
Produces less sound than expected for a big motor.
Fully covered unit with grommets for Q-Meg nozzles.
Easily switch between chemicals with a knob.
The different types of blades meant for various types of materials are hard to discern due to the absence of part number codes.
As far as durability and reliability goes, you want a unit that’s protected from moisture particles bouncing off of whatever surface you may be cleaning and one that has thermal protection so the motor doesn’t burn out from extended use.
The hose should be long enough to maneuver around without jerking the unit mounted on the wall and also rust-proof with sturdy wand and trigger.
A common mistake that people new to pressure washer make is choosing a model simply based on the high numbers such units are rated. Believe me, getting the unit with the most power for your budget is totally fine, but there is more to this than meets the eye.
The cleaning power of a pressure washer can be measured by using several methods. You could use the motor/engine horsepower (HP), Amps, and Watt rating, or you could use the three or two most important numbers not related to these engine ratings. You should look out for the output in gallons per minute(GPM), pounds per square inch(PSI), and the combination of both GPM and PSI, cleaning power (CP) which you can get by multiplying PSI with GPM.
Cleaning power varies from a few thousand to tens of thousands. What it really means is that you’ll be able to get rid of a ten-year-old stain on your driveway if the pressure washer has a larger CP rating, but if the washer lacks proper pressure adjustment module, you’ll likely destroy fragile surfaces using the same pressure setting.
So, if you do not need hardcore stain remover, you might want to consider something in the middle or lower range.
Design and features
The design and features of the pressure washer matter a lot. If the manufacturer decides to build the unit with durable, heavy-duty elements, then they’ll most likely support all of that with a sturdy frame which is pretty handy especially in a wall mount pressure washer. This frame serves as a support for holding the motor, protecting the engine, and for storing Q-Meg nozzles.
With any of the pressure washer above, you can easily clean fences, vinyl siding, walls, garbage cans, driveway or garage floor, and lawn furniture. If you’re dealing with a substance or stain that isn’t water-soluble, these pressure washers let you combine detergent or chemicals with no hassle.
One advantage electric pressure washers have over gas power pressure washer ones is the fact that you can use them in an enclosed space without worrying about emissions or fumes.
