How will you be using the pressure washer? Do you intend to clean your car, truck, garage floor, sidewalk, patio furniture, pool side, driveway or house with it? Determining the exact parameters of usage will help in finding the right sized tool for your needs. This is an excellent way to get started in picking the right pressure washer. At least you won’t overspend on something that will never be fully utilized nor under spend on something that you will eventually outgrow.
Once you have highlighted all the applications you plan for your pressure washer it is time to decide whether you will look at commercial grade or industrial grade washers. Commercial grade washers are cheap and reliable but not blessed with heavy pressure or cleaning prowess. On the other hand Industrial washers are effective, high in efficiency and have lots of power but they cost a lot. Plus industrial washers are huge with large compressors, tanks and require a specialized storage space.
Do you need lots of power or are you looking for something that you can carry around the house? Some people want a pressure washer solely for their backyard and home exterior. Others want it to be portable so that they can clean their cars, trucks, furniture and carry it with them to camping trips and the outdoors. The more power a pressure washer has the bulkier and heavier it is. On the other hand the lighter and portable a pressure washer is, the less power and pressure it generates.
Pressure washers operate using a simple mechanism. The pump draws water from a sump or tank by sourcing power from a motor or engine and then increases the pressure of water to the hose or outlet. Now you have to decide on many things here such as whether to go for electric or gas power, the design of the wand and hose as well as the spray pattern you need. Also, consider the necessity of interchangeable nozzles. Having this possibility helps in future to multitask.
This is the most important consideration to make. However, you can only make this decision after deciding the power, portability, usage and application. Pressure washers are rated with PSI and GPM numbers. Each variable measures a specific ability of the washer. PSI measures the pressure of water delivered by the washer and helps determining the power output. On the other hand GPM measures the total volume of water delivered by the washer. It tells you how fast a washer can clean and how effective it is in removing debris.


washer criticSize, power or technology alone does not make a pressure washer stand out. Ultimately it boils down to one simple fact – what are your needs? Do you only plan to wash car interiors? Maybe handle your entire pool area and patio furniture? Do you prefer eco-friendly washers or energy efficient washers? These are a just a few questions you have to answer. There are many other things to take into consideration but finding out why you need a pressure washer is paramount among them. Different homeowners have varying needs and hence will rate different pressure washers as per personal experience. Reviews on Amazon and other sites usually aren’t the best way to select a pressure washer since someone else cannot determine your exact requirements.

Types of Pressure Washers Reviewed on PressureWasherCritics.com

Pressure washers can be classified on the basis of the temperature of water or by the motor it uses. Accordingly there are cold water, hot water, electric and gas powered pressure washers.

Gas Pressure WashersElectric Pressure WashersHot WaterCold Water

Gas Pressure Washers

Gas power are portable pressure washers that operate out in the open with greater pressure and increased flow rates for industrial applications. Unfortunately, they can only be used outdoors since the motor produces carbon monoxide, toxic even in the slightest concentrations.

  • Best For – Industrial applications, regular use, heavy duty application.
  • Pros – High power, portability, adjustable pressure and volume of flow.
  • Cons – Expensive, costly to maintain, noisy and requires fuel to operate.

Electric Pressure Washers

Electric pressure washers are limited in the total power output and can be used both indoors as well as outdoors. These are usually less noisy and have sufficient power for most commercial uses although industrial application may not be its forte.

  • Best For – Light usage that requires both indoor and outdoor application.
  • Pros – Efficient, less noisy, easier to maintain and less moving parts.
  • Cons – Expensive, limited by the length of cord, usually bulky in design and non-portable, needs safety precautions as electricity and water do not go well together.

Hot Water Pressure Washers

Hot water pressure washers use a boiler or heater to increase the temperature of water mixed with soap solution before venting it out at a high pressure and volume. This requires a larger engine or motor as it will operate a heating element as well as the pump. They are expensive in comparison with cold water washers but require less soap solution.

  • Best For – Washing patio, home exteriors and heavy duty use.
  • Pros – High powered, greater efficiency with less expense.
  • Cons – Expensive, additional heating component increases cost of repairs and needs caution when handling because of high temperatures.

Cold Water Pressure Washers

These are the cheapest of all pressure washers and they can run on a small electric motor. Usually they need less maintenance because of fewer parts and last longer. Also they are inexpensive with replacement parts usually costing less. However, they need more soap solution and develop lower pressure with a reduced GPM rating.

  • Best For – Washing car interiors, furniture and light applications.
  • Pros – Inexpensive, less maintenance, run on electric motors and usually portable.
  • Cons – Less efficient than hot water pressure washers, need a lot of soap solution and have smaller tanks.
